android-hidden-secret_how-to-find-out-who-sniffs-out-your-android-mobile-andrid-hidden-codes

Maybe little know about this embedded Android mobile smart phone features but there is a few mobile code cheats that can help you find out a little bit about your phone security, that's pretty handy for anyone who really wants to know whether mobile phone is being sniffed / tapped on Android software level and can give you an idea on how much your smart phone data is protected or are you being a target of someone's secret surveillance, of course this info is just on Android firmware embedded features level and if your mobile is somehow hacked or trojanned the information that can show could be not adequate, but still it is a good info to know. I'm sure you'll be surprised how much embedded Android features are there for the controllers (Google staff) 🙂
 


 

1. Information about telephone, battery status and statistics about telephone use


*#*#4636#*#* 

To get information about battery, usage statistics and device.
 

2. Are Smart Phone Voice / SMS Transfers on?

*#21#

This combination of numbers and symbols allows you to understand where your mobile is Transferring Calls, SMS-es or other messages. If you type this code and click call the phone screen should show any numbers to which any data is being transferred, if your phone is okay and not tapped you will get a message the phone call transfers and sms transfer is disabled. Always keep in mind that there is a danger for your info / data or even billings to be tapped already as Android is non-free software, so even if that code returns no transfers you're still insecure at the hands of Google's mercy.


3. Where are calls and SMS-es transffered in case if Voice / SMS Transfers are on?
 

*#62#

This codes shows where are your input Calls and SMS-es are being transferred once someone is calling you and he is unable to reach you. At best case the inbound calls will be redirected as voice mail format to voice mail box of the number of your mobile operator.


4. Deactivate all kind of Phone Voice / SMS Transfers (Redirects) for security
 

##002#

By inputting above code you can deactivate all kind of redirects, which were prior configured at your mobile phone. The code is universal one and should work not only in Android but across all smart phones including IPhones. It is a recommended one especially if you're planning to travel in foreign country or region due to the roaming phone expenses.
 

5. Get IMEI (International Mobile Equipment Identifier) phone info

*#06#

Above code provides information about the ID number of the mobile phone th so called IMEI (International Mobile Equipment Identifier). Using the email a mobile phone that has been recently stolen can be easily found, because the device is emitting its IMEI number to the mobile phone operator, nomatter what kind of SIM Card is inserted in the phone.

 

6. How to protect yourself from criminals and spies?


You can use alternative Messanger  Chat / Voice Clients such as: Telegram, Wickr, Signal or Alternatively run your own Jabber server and use it to securily communicate with your friends and relatives


Do not install an unknown source program to mobile phone, abstain from charging the phone on airports and suspicious free "charging" points, abtain from using any free wifi networks whose owner you don't know personally. Beware while browsing as there are websites that could infect you with javascript viruses and terrible phone malware stuff, to be safe make sure you have some kind of Antivirus software installed on the phone just in case.
Be vigilant!

 

7. Bigger list of Codes working across some of Android versions providing various phone stats and info (not working on all mobiles but might be working on yours)

howto-find-out-who-sniffs-out-about-your-Android-android_secret_codes_for_your_android_mobile_phone

Here is a list also with a useful codes for some of Android version releases (this will not work on IPhones)

ArchAngels day 8 of November, the day of All Angels and Archangels – Who are the ArchAngels and why we should venerate them?

Wednesday, November 8th, 2017

Archangel_Michael_A_Warrior-Angel-protector-of-all-Christians

Today on 8th of November, the Bulgarian Orthodox Church is celebrating the day of Arch Angels (Primary Angels) who stay always near God Almigthy the Creator of this world.

Accroding to Christianity, there are seven main angels called (Arch Angels),  each of the Archangels has its own specific ission, one is a messanger of secrets that has to be revealed to man, other is a healer of infirmities.

The names of the Seven main Arch Angels in Eastern Orthodox Christian faith are:

Archangel_Michael_Holy_Orthodox-christian-icon

 

  •     Michael in the Hebrew language means "Who is like God?" or "Who is equal to God?" Michael has been depicted from earliest Christian times as a commander, who holds in his right hand a spear with which he attacks Lucifer/Satan, and in his left hand a green palm branch. At the top of the spear there is a linen ribbon with a red cross. The Archangel Michael is especially considered to be the Guardian of the Orthodox Faith and a fighter against heresies.

     

    Holy-Archangel-Gabriel_orthodox-icon
     

 

  •     Gabriel means "God is my strength" or "Might of God." He is the herald of the mysteries of God, especially the Incarnation of God and all other mysteries related to it. He is depicted as follows: In his right hand, he holds a lantern with a lighted taper inside, and in his left hand, a mirror of green jasper. The mirror signifies the wisdom of God as a hidden mystery.

     

    Holy-Archangel-Raphael-orthodox-icon
     

  •     Raphael means "It is God who heals" or "God Heals" (Tobit 3:17, 12:15). Raphael is depicted leading Tobit (who is carrying a fish caught in the Tigris) with his right hand, and holding a physician's alabaster jar in his left hand.

     

    Archangel-Uriel-orthodox-icon
     

  •     Uriel means "God is my light," or "Light of God" (II Esdras 4:1, 5:20). He is depicted holding a sword against the Persians in his right hand, and a flame in his left.

     

    Archangel_Selathiel_Herodion-of-Patras_1840_Russia
     

  •     Sealtiel means "Intercessor of God." He is depicted with his face and eyes lowered, holding his hands on his bosom in prayer.
    Archangel-Jegudiel-holy-orthodox-icon

     
  •     Jegudiel means "Glorifier of God." He is depicted bearing a golden wreath in his right hand and a triple-thonged whip in his left hand.
    Archangel-Barachiel-the-archangels-the-peace-blessed-by-God
  •     Barachiel means "Blessed by God." He is depicted holding a white rose in his hand against his breast.

     

    holy-Archangel-Jerahmeel
     

  •     Jerahmeel means "God's exaltation." He is venerated as an inspirer and awakener of exalted thoughts that raise a person toward God (II Esdras 4:36). As an eighth, he is sometimes included as archangel.

 

The accent of todays feast (Synaxis of the Holy Archangel Michael and the other Budiness Powers) is Archangel Michael, so I find it worthy to say few words more about Archangel Michael.

Archangel Michael is "the keeper of the souls and a fighter against evil in the world".

That is the reason why Archangel Michael is often depicted with a firy spear at hand piercing the devil.
In the Eastern Orthodox Christian faith there is no other God servent guardian angel with so many duties.

Archangel Michael is:

1. Chiefman of the Heavenly (Bodiless) Powers

2. A fighter against the spirits of wickedness (spirits of evil)

3. A Protector of Christians from the devil

4. A Chief Leader of Christ's armies against the pagans and heresies

5. A Keeper of All Christian Souls

6. The Archangel that is present on mens deathbed and divides the soul from the body
 

Archangel_Michael_piercing-the-devil

The dividing of the soul on a men deadbed is perhaps one of the most important of Archangel Michael's missions it does stop our earthly way and collects the soul. Just before this according to our Orthodox Christian faith, each one of us Christians is given by God during Baptism with a personal guardian angel, who keeps him from perils, troubles and sorrows.

Each-Christian-has-A-Guardian_Angel

The Guardian Angel each Christian receives during baptism

But man has to be cautious, the guardian angel does cries watching at us when we live careless sinful life, he is not enforced to keep for us eternally if we wish to live a life without faith or God, then he leaves us crying for our fallen state.

The more sinful life a man leads in this life, the more clean his soul is being collected by Archangel Michael.
The food we put on table Archangels day is a feastful one, it is a tradition here in Bulgarian to eat Lamb meat the so called (Kurban) and a special breads are prepared, the so called Rangel's Bread, there are 2 types actually (Bogovica and Rangelovo bludo).
A boiled wheat is also a common meal on the table, beans and of course red wide.

The meaning of 8 of Novembers feast is to celebrate the Congregation Integrity of all Angel ranks (just like in Army we Christians believe that Angels and they all work together for the same goal the salvation of each man's soul)

Archangel-Michael-collecting-soul-of-a-dead-man

Because of Archangel Michael being so famous to divide the soul from the body of the dying, perhaps it is not a coincidence why few days before 8th of November on the previous Saturday the Church calendar marks A Memorial day for all those who died (The so called Zadushnica feast), the meaning of which is that people give out food and goods for the remembrance of the souls of their departed beloveds, praying with hope for the deceased people begging God to have mercy over their souls. Because of this unwritten connection between the men deadbed and Archangel michael often in people's tradition ArchAngel Michael is seen to be an Angel of Death and historically has been highly venerated all across the Christiandome.

It used to be an old people believe that if one smiles on his death hour this means ArchAngel Michael has granted him to heaven and as a prize has given him a Golden Apple (in spiritual sense).

Synaxis-Assembly-of-All-The-Holy-Heavenly-Powers-Archangel-Michael

Let the Holy Archangels; Michael, Gabriel, Raphael, Uriel Selathiel, Jegudiel, Barachiel, Jarahmeel along with all angels and bodily powers pray for us so we find ways to become better people and clean up from our numerous sins by repentance.
Amen

Email Linux alternative text console clients to Thunderbird, fetchmail, Mutt, fetchmail + Alpine how to

Saturday, November 4th, 2017

linux-email-alternatives-for-text-console-email-fetching-gathering-alternative-to-thunderbird-and-evolution-howto

As a GNU / Linux user you might end up searching for the best email client to satisfy your needs, for those who used so far Outlook Express on M$ Windows first switch to GNU / Linux the most likely one to choose is either Mozilla Thunderbird or GNOME's Evolution default Mail Clientbut what more text / console programs are there that will allow you to easily check email via POP3 and IMAP on Linux?

 

1. Install Fetchmail and use to collect and copy your emails from remote server to your local machine
 

 SSL enabled POP3, APOP, IMAP mail gatherer/forwarder
 fetchmail is a free, full-featured, robust, and well-documented remote mail
 retrieval and forwarding utility intended to be used over on-demand TCP/IP
 links (such as SLIP or PPP connections).  It retrieves mail from remote mail
 servers and forwards it to your local (client) machine's delivery system, so
 it can then be read by normal mail user agents such as mutt, elm, pine,
 (x)emacs/gnus, or mailx.  The fetchmailconf package includes an interactive
 GUI configurator suitable for end-users.

To install it, issue:
 

apt-get install –yes fetchmail procmail


To configure fetchmail to gather your mail from your POP3 / IMAP mailbox, create below
.fetchmailrc configuratoin and modify according to your account

 

# vim .fetchmailrc

 

#### .fetchmailrc
 set daemon 600
 set logfile fetchmail.log

 poll the_mail_server_hostname proto POP3

  user "Remote_Username" pass "PASSWORD=" is "local_username" preconnect "date >> fetchmail.log"
 #ssl
  fetchall
  #no keep
  no rewrite
  mda "/usr/bin/procmail -f %F -d %T";


Here is also few words on each of the .fetchmailrc config options

set daemon 600 The fetchmail binary with run in the background in daemon mod and fetch mail from the server every 600 seconds or 10 minutes.

set logfile fetchmail.log This will set the directory and file name of the fetchmail user log file. Eveytime fetchmail recieves an email, checks the pop3 server or errors out you will find an entry here.

poll the_isp_mail_server proto POP3 This line tells fetchmail what mail server to contact, in theis case "the_isp_mail_server" and to use the "POP3" protocol.

user "remote_user_name" pass "PASSWORD" is "local_username" preconnect "date >> fetchmail.log The user directive tells fetchmail what the name of the user on the remote mail server is for example "remote_user_name". The pass directive is simply the password you will use for the remote user on the mail server. The "is" directive is optional. It tells fetchmail to deliver mail to a diferent user name if the user on the remote mail server and the local machine are different. For example, I may be using the name "joe.doe" on the mail server, but my local user name is "jdoe". I would use a line like user "joe.doe" pass "PASSWORD" is "jdoe". The preconnect command simply adds the current time and date to the fetchmail log file every time fetchmail checks for new mail.

ssl The "ssl" directive tells fetchmail to use encryption when connecting to the pop3 mail server. Fetchmail will use port 995 instead of port 110 for un-encypted mail communication. In order to use ssl the remote mail server must be able to use ssl. Comment out this directive if you do _not_ use pop3s.

fetchall Fetchall just means to fetch all of the mail on the mail server no matter what the "read" flag is. It is possibly to read mail through many different processes. If you use another mail client from another location, for example you could have read you mail and kept it ont he server, but marked it with the "read" flag. At this point if you did _not_ use the "fetchall" flag then only mail marked as new would be downloaded.

no keep Once the mail is downloded from the mail server fetchmail is to tell the server to remove it from the server. You may choose to comment this option out if you want to leave all mail on the server.

no rewrite Do not rewrite headers. When fetchmail recieves the mail you do not want any of the headers mangled in any way. This directive tells fetchmail to leave the headers alone.

mda "/usr/bin/procmail -f %F -d %T"; The mda is your "mail delivery agent. Procmail is the program that fetchmail will hand the mail off to once it is downloaded. The argument "-f %F" logs who the mail if from and "-d %T" turns on explicit delivery mode, delivery will be to the local user recipient.

For configuring multiple mailboxes email to be gathered to local machine through fetchmail add to above configuration, some more config similar to this:

 poll mail.example.com protocol pop3:
       username "admin" password "your-plain-text-password" is "username" here;
       username "what-ever-user-name" password "Just-another-pass#" is "foreman" here;

  poll mail.example.org protocol pop3 with option sslproto '':
       user "whatever-user1" password "its-my-pass" mda "/usr/bin/procmail -d %T":   user "whatever-user1" password "its-my-pass" mda "/usr/bin/procmail -d %T

 


Because as you can see fetchmail keeps password in plaintext it is a best security practice to set some good file permissions on .fetchmailrc just to make sure some other local user on the same Linux / Unix machine will not be able to read your plaintext password, to do so issue below command.
 

chmod 600 ~/.fetchmailrc

 

For the purpose of logging as we have it into the config you will also need to create new blank file fetchmail.log
 

touch fetchmail.log


Once fetchmail all your emails you can use mail command to view your messages or further configure alpine or mutt to read the downloaded messages.

 

2. Use Alpine text based email client to check your downloaded email with fetchmail
 

Alpine is Text-based email client, friendly for novices but powerful
 Alpine is an upgrade of the well-known PINE email client.  Its name derives
 from the use of the Apache License and its ties to PINE.

In other words what Alpine is it is a rewritten and improved version of the good old PINE Unix email client (for those who remember it).

To give alpine a try on Debian / Ubuntu install it with:

 

apt-get install –yes alpine pilot

 

Mutt-text-console-linux-email-client

 


3. Use MuTT advanced and much more colorful text email client to view your emailbox

mutt-text-email-client-logo-dog

 Mutt is a sophisticated text-based Mail User Agent. Some highlights:
 .
  * MIME support (including RFC1522 encoding/decoding of 8-bit message
    headers and UTF-8 support).
  * PGP/MIME support (RFC 2015).
  * Advanced IMAP client supporting SSL encryption and SASL authentication.
  * POP3 support.
  * ESMTP support.
  * Message threading (both strict and non-strict).
  * Keybindings are configurable, default keybindings are much like ELM;
    Mush and PINE-like ones are provided as examples.
  * Handles MMDF, MH and Maildir in addition to regular mbox format.
  * Messages may be (indefinitely) postponed.
  * Colour support.
  * Highly configurable through easy but powerful rc file.

 

To install MuTT:

 

linux:~# apt-get install –yes mutt

Configuring mutt if you don't have priorly set-up with fetchmail to collect your remote e-mails, you might want to try out .mutt's email fetch features to do so you will need a .muttrc configuration like that:
 

# Automatically log in to this mailbox at startup
set spoolfile="imaps://User_Name:Your-Secret-Password@mail.example.com/"
# Define the = shortcut, and the entry point for the folder browser (c?)
set folder="imaps://mail.example.com/"
set record="=Sent"
set postponed="=Drafts"

You might also omit placing the password inside .muttrc configuration as storing the password in plaintext might be a big security hole if someone is able to read it at certain point, but the downside of that is you'll be asked by mutt to fill in your email password on every login which at a point becomes pretty annoying.
 

If you face problems with inability of mutt to connect to remote mail server due to TLS problems, you can also try to play with below configurations:
 

# activate TLS if available on the server
 set ssl_starttls=yes
 # always use SSL when connecting to a server
 set ssl_force_tls=yes
 # Don't wait to enter mailbox manually
 unset imap_passive        
 # Automatically poll subscribed mailboxes for new mail (new in 1.5.11)
 set imap_check_subscribed
 # Reduce polling frequency to a sane level
 set mail_check=60
 # And poll the current mailbox more often (not needed with IDLE in post 1.5.11)
 set timeout=10
 # keep a cache of headers for faster loading (1.5.9+?)
 set header_cache=~/.hcache
 # Display download progress every 5K
 set net_inc=5
 

 

Once you have the emails downloaded with fetchmail for your mailbox mutt should be showing your email stuff like in below screenshot
 

linux:~$ mutt

 

 

Mutt-text-console-linux-email-client

Of course a very handy thing to have is w3m-img text browser that displays images as it might be able to open your pictures attached to email if you're on a physical console tty.

I'll be curious to hear, if you know of better and easier solutions to check mail in console, so if you know such please drop a comment explaining how you check your mail text.

Why don’t you use Window Maker GNU Step to improve your computer interaction performance

Monday, October 30th, 2017

Why-dont-you-use-Window-Maker-graphical-environment-for-your-GNU_Linux-FreeBSD-desktop

If you're pissed off too already of GNOME 3 Unity / GNOME 3 Flashback and KDE Plasma  as I am you perhaps are looking for something more light weigth but you're not okay with default Debian Cinnanom GUI environment or you don't feel confortable for system administration jobs and programming with XFCE then perhaps you would like to give a try to something more old school but build with good design in Mind.

Those who are fans of the evil genius Steve Jobs (as Richard Stallman use to call him), definitely Remember NeXT company and the revolutionary Graphic Environment they tried to develop NeXT Step then you'll be happy to hear about GNUStep  which historically was called AfterStep and is a Free Software remake of NextStep graphical environment for Free and Open Source operating systems (FOSS) such as GNU / Linux and FreeBSD / OpenBSD / NetBSD etc.

Amanda_the_panda_mascot_of_window_maker-graphical-environment-system

Amanda the Panda is the mascot of Window Maker. She was designed by Agnieszka Czajkowska.

The good thing about Window Maker and the complete bunch of desktop environment GNUStep is it much lighter and less complex than the more and more becoming bloated modern Free Software graphical environments, it definitely easifies the way the user interacts with basic browsing with Firefox / Opera, terminal code writting or command system administration and basic chat functionalities such as with Gajim or Pidgin and basic email writting operatins be it with some text email client such as Mutt or with Thunderbird. Its great also to reduce the overall load the Operating System puts on your brain so you can have more time to invest in more useful stuff like programming.

windows-maker-increase-performance-of-work-with-your-computer-howto-wmaker-screenshot

After all simplicity in Operating System is a key for an increased productivity with your computer.
Besides that stability of Window Maker is much better when compared to GNOME and GNOME 2 fork MATE graphical environment which nowadays in my opinion is becoming even more buggy than it used to be some years ago.

Below is how Window Makers site describes Window Maker:

"Window Maker is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment. In every way possible, it reproduces the elegant look and feel of the NEXTSTEP user interface. It is fast, feature rich, easy to configure, and easy to use. It is also free software, with contributions being made by programmers from around the world.

Window Maker has a stable user interface since many years and comes with a powerful GUI configuration editor called WPrefs, which removes the need to edit text-based config files by hand. It supports running dockapps which make everyday tasks such as monitoring system performance and battery usage, mounting devices or connecting to the internet very easy. Please see the features section for more specifics on what Window Maker can do, and how it compares with other popular window managers."

Window Maker is bundled with a number of useful applications which gives ability to put Dock applets easily for easily intearcive desktop update of current Weather Report, Monitoring Network Traffic, TV Player (video4linux), laptop battery info dock, CD player and Volume control management app, text editor, pdf viewer, integrated Mail application, Calculator, RSS Reader, GNUStep games and much useful things to customize from the desktop resembling many of the basic features any other graphical environment such as GNOME / KDE Provides.

The User Interface (UI) of Window Maker is highly configurable with an integrated WMaker tool called

WPrefs

Why-dont-you-use-Wmaker-for-better-desktop-performance-Windowmaker_colour_preferences

All generated settings from WPrefs (Window Maker Prefernces) GUI tool are to be stored in a plaintext file:
 

~/GNUstep/Defaults/WMRootMenu

All Wmaker configurations are stored inside ~/GNUstep/ (Your user home GNUStep), so if you're to become its user sooner or later you will have to get acquired to it.

Wmaker is very minimalist and the performance is killing so Window Maker is perhaps the number one choice Graphical Environment to use on Old Computers with Linux and BSD.

Well yes it is true Window Maker is not a spoon for every mouth, those who want to have more confortable desktop environment better look out at other options as Window Maker is Unix / Linux graphical environment that fits better hackers, computer developers and system administrators.

Anyhow if you have some old family member that has to use an old computer architecture and the person is only to use mainly just browser to check email, youtube and basic surfing then Wmaker will be a great choice as it will consume little CPU and Memory much less than the heavy and computer resources sucking GNOME and KDE.

I've historically used Wmaker also with its teminal emulator rxvt (VT102 terminal emulator for the X Windows System) which is a kinda of improved version of xterm (the default terminal program bundled with Xorg server), but for those who are already used to Gnome Terminal nice tabs perhaps that would be not the terminal of choice.

rxvt was build to match well the look and feel of AfterStep and consequently Wmaker, its scrollbar was aiming to very much resemble NeXTStep style scrollbar

Most "custom" shortcuts are used to launch specific applications. To add your own keyboard shortcut for an application, go to the "Applications Menu Definition" panel in the Preferences app.  Select the application item in the menu for which you want to create a shortcut, then use the "capture" button to capture the keystrokes you want to assign to that item.  In the screenshot, I've assigned Mod1 + W to open Firefox.

Above  screenshot shows how to map the Run Application keyboard bind to behave like GNOME Run application ALT + F2

Customizing background of Window Maker

Because WMaker is so simple made and targetting more of a developer audience for use it doesn't have a special graphical interaface to set a Background if you like so, but instead you need to use a wmsetbg command to do so:
 

wmsetbg -s -u filename.jpg

 

WMSetBG command stands for WindowMaker Set Background


If you're too lazy to install and start configuring wmaker, there is a Window Maker LiveCD, you can run Window Maker through LiveCD in Virtual Machine such as VirtualBox to get feeling what you're about to get if you install and start using Wmaker on your Computer.

Well at first with Window Maker you might feel confused and quickly irritating missing the already established way to work with your computer, but that's just for a starter sooner you will realize, that for using a limited number of applications for work wmaker, makes you much more efficient. Moreover using your computer with Wmaker can rewire your brain circuits to think a little bit different.

Once you switched to Window Maker you will likely want to have a graphical option to connect to Wireless Networks especially if you're using Wmaker on a notebook it is convenient to not always manually do scan for networks with

commad and use wpasupplicant command to connect instead you can just install wicd and stop default Gnome Network Manager (called Network Manager), you can do so by running as root:
 

service network-manager stop
apt-get install wicd wicd-gtk
service wicd start

What is this directory /run/user/1000 on Debian and Fedora GNU / Linux?

Monday, October 23rd, 2017

what-is-this-folder-directory-run-user-1000-in-debian-debianfedoraubuntu-linux

So what are these /run/user/1000, /run/user/0, /run/user109, /run/user/1000 showing in my df -h I'm I hacked or what?

root@noah:~# df -h|grep -i tmpfs
tmpfs 201M 22M 179M 11% /run
tmpfs 1001M 0 1001M 0% /dev/shm
tmpfs 5,0M 4,0K 5,0M 1% /run/lock
tmpfs 1001M 0 1001M 0% /sys/fs/cgroup
tmpfs 201M 0 201M 0% /run/user/0
tmpfs 201M 36K 201M 1% /run/user/1000
tmpfs 201M 16K 201M 1% /run/user/109

 

/run/user/$uid is created by pam_systemd and used for storing files used by running processes for that
user. These might be things such as your keyring daemon, pulseaudio, etc.

Prior to systemd, these applications typically stored their files in /tmp. They couldn't use a location in
/home/$user as home directories are often mounted over network filesystems, and these files should not be
shared among hosts. /tmp was the only location specified by the FHS which is local, and writable by all
users.

However storing all these files in /tmp is problematic as /tmp is writable by everyone, and while you can
change the ownership & mode on the files being created, it's more difficult to work with.

However storing all these files in /tmp is problematic as /tmp is writable by everyone, and while you can
change the ownership & mode on the files being created, it's more difficult to work with.

So systemd came along and created /run/user/$uid.
This directory is local to the system and only
accessible by the target user. So applications looking to store their files locally no longer have to
worry about access control.

It also keeps things nice and organized. When a user logs out, and no active sessions remain, pam_systemd will wipe the /run/user/$uid directory out. With various files scattered around /tmp, you couldn't dothis.

Should mention that it is called $XDG_RUNTIME_DIR, documented at 8 standards.freedesktop.org/basedir-spec/basedir-spec-latest.h‌​tml.

What if: I have started a "background" computation process with nohup, and it saves its intermediate results/data in a temp file. Can I count on it not being wiped while the process is running, or it will be wiped, and the process started with nohup will loose its data? 

It's unlikely to be wiped, but /run/user is a tmpfs filesystem in debian, ubuntu and fedora, so it'll be limited.

What if the pidfile is a service running under root.
Should it's PID go under /var/run or /var/run/user/0 ?

If since there is no active sessions will it be removed? 

This directory contains system information data describing the system since it was booted.
Files under this directory must be cleared (removed or truncated as appropriate) at the beginning of the boot process.

The purposes of this directory were once served by /var/run. In general, programs may continue to use /var/run to fulfill the requirements set out for /run for the purposes of backwards
compatibility.

Programs which have migrated to use /run should cease their usage of /var/runexcept as noted in the section on /var/run.

Programs may have a subdirectory of /run; this is encouraged for programs that use more than one run-time file.

Users may also have a subdirectory of /run, although care must be taken to appropriately limit access rights to prevent unauthorized use of /run itself and other subdirectories.

In the case of the /run/user directory, is used by the different user services, like dconf, pulse,systemd, etc. that needs a place for their lock files and sockets. There are as many directories as
different users UID's are logged in the system.

Play Midis on Linux / Make Linux MIDI Ready for the Future – Enable embedded MIDI music to play in a Browser, Play MIDIs with VLC and howto enjoy Midis in Text Console

Play Midis on Linux or Make Linux MIDI Ready for the Future – Enable embedded MIDI music to play in a Browser, Play MIDIs with VLC and howto enjoy Midis in Text Console HOWTO

 

Playing MIDI has been quite a lot of fun historically,

if you grow up in the days when personal computers were still young and the Sound Blaster was a luxury, before the raise of Mp3 music format, you have certainly enjoyed the beeping of PC Speaker and later on during 386 and 486 / 586 computers the enjoyment of playing tracked music such as S3M and MOD,

in that good days playing MIDI music was the only alternative for PC maniacs who doesn't own a CD Drive (which itself) was another luxury and even thouse who had a CD ROM device, were mainly playing music in CD audio format (.CDA).
Anyhow MIDI was a cheap and a CPU unintensive way to listen to equivalent of favourite popular Audio Songs and for those who still remember many of the songs were recreated in MIDI format, just with a number of synthesized instruments without any voice (as MIDI is usually).

The same was true also for the good old days of raise of Mobile Phones, when polyphonic was a standard as CPU power was low MIDI was a perfect substitute for the CPU heavy Encoded MP3s / OGG and other formats that required a modern for that time Intel CPU running in 50+ Mhz usually 100 / 166Mhz was perfect for the days to play Mp3 but still even on that PCs we listened to Midi songs.

Therefore if you're one of those people like me who still enjoy to play some Midi Music in the year 2017 and feel a bit like Back into the Future movie and a Free Software fan and user, especially if you're a novice GNU  / Linux Free Software user, you will be unpleasently surprised that most today's default Linux distributions doesn't have an easy way to play Midi music format out of the box right after install.

Hence below article aims to give you an understanding on

How you can play Midi Music on GNU / Linux Operating System

First, lets Prepare to load necessery Linux kernel modules to make sure MIDI can be played by soundcard:

In /etc/modules make sure you have the following list of modules loaded:
 

linux-desktop:~# cat /etc/modules
3c59x
snd-emu10k1
snd-pcm-oss
snd-mixer-oss
snd-seq-oss

!Note the modules are working as of time of writting and in time can change to some other modules, depending on how the development of ALSA (Advanced Linux Sound Architecture) goes, and if the developers decide to rename the upmentioned modules

If you just have added the modules to /etc/modules with vim / nano to reload modules into the Linux kernel run:

 

linux-desktop:~# modprobe -a


Secondly, Installing a whole bunch of MIDI music related program tools can be achieved in Debian by installing the multimedia-midi package, e.g.:

 

linux-desktop:~# apt-get install –yes multimedia-midi

 

1. Playing Midi in Graphical environment with a double click using VLC


How to make MIDI easy listanable in Linux graphical environment like GNOME / KDE / XFCE desktop ?

 

If you want to make Midi music execution sa easy as  just clicking on the .MIDI file format on Linux you can do that with a midi extension available for VLC (Video Lan Client) Universal Multi Platform Media Player player

To install it on Debian Ubuntu GNU / Linux
 

# apt-get install –yes vlc-plugin-fluidsynth

 

Необходимо е да се изтеглят 6754 B архиви.
След тази операция ще бъде използвано 35,8 kB допълнително дисково пространство.

Processing triggers for libvlc-bin:amd64 (2.2.6-1~deb9u1) …


Besides making your MIDI play on the GUI environment easy as a a point and click VLC will also be able to play MIDIs on GNU / Linux from your favourite browser (nomatter Firefox / Chrome or Opera), even though the player would play in a new PopUP Window it is easy to select once MIDI file from a random website for example – here is a directory listing of Webserver with Doom II Soundtrack in MIDI format , click over any file from list and Choose option for VLC to always remember that MIDI files has to be opened with VLC player.
 


2. Enable Firefox / IceWeasel browser to Support Website embedded MIDI files

 

 

So VLC could make you listen the downloadable MIDIs from Web pages but,
 

What if you have stumbled on an old website which was configured with very OLD HTML Code to play some nice music (or even different MIDI songs) for each part of the website (for each webpage) and you want to have the Websites created with embedded MIDIs to automatically play on Linux oncce you visit the site?


Sadly default support in Browser for MIDI across all GNU / Linux, I've used so far never worked out of the box, not that still anyone is developing modern websites with MIDIs, but still for the sake of backward compitability and for sake of interactivity it is worthy to enable embedded MIDI support in Linux

But with a couple of tunings as usual GNU / Linux can do almost everything, so here is how to enable embedded browser support for Midi on Linux (That should work with minor modifications not only on Debian / Ubuntu / ArchLinux but also on Fedoras, CentOS etc.
If you try it on any of this distributions, please drop a short comment and tell me in few lines how you made embedded midi worked on that distros.

 

apt-get install –yes timidity mozplugger

Next do restart firefox

Sometimes in order to work you might need to delete /home/[YOUR_USERNAME]/.mozilla/pluginreg.dat and restart firefox again, e.g. make a backup and give it a try:

 

cp -rpf /home/hipo/.mozilla/pluginreg.dat /home/hipo/.mozilla/pluginreg.dat.bak
rm -f /home/hipo/.mozilla/pluginreg.dat

 

Another good tip as talking for embedding MIDI support is to embed XPDF to render PDF pages inside the Browser, by default this is done by GNOME's Evince PDF reader but as it is sometimes buggy and might crash it is generally a good idea to switch to xpdf instead, if for some reason PDF is not directly displaying in browser or suddenly stopped working after some distro uipgrade, you might want to do below as well:
 

apt-get install xpdf

vim /etc/mozpluggerrc

Fin d and Comment out the line starting with:

It should look like this afterwards:

 Repeat Swallow ….
 

text/x-pdf: pdf: PDF file
#      repeat swallow(documentShell) fill: acroread -geometry +9000+9000 +useFrontEndProgram "$file"
        repeat noisy swallow(Xpdf) fill: xpdf -g +9000+9000 "$file"
        repeat noisy swallow(gv) fill: gv –safer –quiet –antialias -geometry +9000+9000 "$file"


 

3. Play Midi music in Linux text console / terminal


There is a console tool that historically has been like the Linux standard for playing midis over the years as I remember, its called timidity

 


To install timidity on .Deb based Linux:
 

linux-desktop:~$ su root
Password:
linux-desktop:~# apt-get install –yes timidity

Необходимо е да се изтеглят 0 B/580 kB архиви.
След тази операция ще бъде използвано 0 B допълнително дисково пространство.
(Reading database … 382981 files and directories currently installed.)

Setting up timidity (2.13.2-40.5) …
Processing triggers for menu (2.1.47+b1) …

 

To test your new MIDI Synthesizer tool and make the enjoyment full you can download Doom 2 extracted MIDI Soundtrack from here
 

Once you have downloaded above Metal MIDI DOOM old school arcade soundtrack and untarred it into your home directory be it ~/doom-midis

A remark to make here is timidity is quite CPU intensive, but on modern Dual and Quad-Core PC Notebooks, the CPU load is not of a big concern.

To test and play with timidity:
 

linux-desktop~$ timidity ~/mp3/midis/*


timidity-playing-doom-midi-bunny-song-on-debian-stretch-gnome-terminal-screenshot
 

hipo@jericho:~/mp3/midis$ aplaymidi -l
 Port    Client name                      Port name
 14:0    Midi Through                     Midi Through Port-0
128:0    TiMidity                         TiMidity port 0
128:1    TiMidity                         TiMidity port 1
128:2    TiMidity                         TiMidity port 2
128:3    TiMidity                         TiMidity port 3

 


We have also the playmidi  (simple midi text console terminal player), which historically was working quite decent and I use it to in the past on my RedHat 6.0 and RedHat 7.0 to listen to my .MID format files but unfortunately as of time of writting something is wrong with it, so when I try to play MIDIs with it instead of timidity I get this erro:

 

$ playmidi *.mid
Playmidi 2.4 Copyright (C) 1994-1997 Nathan I. Laredo, AWE32 by Takashi Iwai
This is free software with ABSOLUTELY NO WARRANTY.
For details please see the file COPYING.
open /dev/sequencer: No such file or directory

Even though I tried hard to resolve that error by loading various midi related MIDI modules and following a lot of the suggestions online on how to  make /dev/sequencer work again it was all no luck.
 

Some people back in the distant year 2005, reported the problem was solved by simply loading snd-seq

But as of time of writting:

 

# modprobe snd-seq

 

Some people said in archlinux's Forum

/dev/sequencer sequencer: No such file or directory

 

is solved by loading snd-seq-oss kernel module, but on my Debian Linux 9.1 Stretch, this ain't work as well :

 

root@jericho:/home/hipo/mp3/midis# modprobe snd-seq-oss
modprobe: FATAL: Module snd-seq-oss not found in directory /lib/modules/4.9.0-3-amd64
root@jericho:/home/hipo/mp3/midis# uname -a;
Linux jericho 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux


Another invention of mine was to try to also link /dev/snd/seq to /dev/sequencer but this produced no positive result either:

 

# ln -sf /dev/snd/seq /dev/sequencer
# ls -al /dev/sequencer
lrwxrwxrwx 1 root root 12 окт  4 16:48 /dev/sequencer -> /dev/snd/seq


Note that after lining in that way I got following error with my attempt to play MIDIs with playmidi

# playmidi *.mid
Playmidi 2.4 Copyright (C) 1994-1997 Nathan I. Laredo, AWE32 by Takashi Iwai

For details please see the file COPYING.
there is no soundcard


Anyhow on some other Linux distributions (especially with Older Kernel versions), some of the above 3 suggested Fix might work perfectly fine so if you have some time give it a try please and drop me  a comment on how it went, you will help the GNU / Linux community out there that way.

Well never mind the bollocks, so

Now back to where I started timidity even though it will play fine it will not give any indication on the lenght of the midi song (precious information such as how much time is left until the end is over).

Hence if you prefer a player that gives you an indicator on how much is left towards the end length of each of the played MIDI file you can give a try to wildmidi:

 

linux-desktop:~$ apt-cache show wildmidi|grep -i description -A 2

Description-en: software MIDI player
 Minimal MIDI player implementation based on the wildmidi library that
 can either dump to WAV or playback over ALSA. It is intended to

If yet not installed install it after becoming admin user:

 

linux-desktop:~$ su root
Password:

linux-desktop:~# apt-get install –yes wildmidi


wildmidi is much less CPU intensive (it uses gstreamer to play (Gstreamer – open source multimedia framework)

And next give it a try by running:

 

linux-desktop:~$ wildmidi ~/mp3/midis/*

 

wildmidi-midi-lenght-status-text-console-player-for-linux-ubuntu-debian-fedora-suse

 

 

4. Editting MIDI files with Free Software and Proprietary MIDI Editor Programs

 


If you want a professional software that can play Midi in a fuzzy interactive GUI way and have some extra possibilities to edit MIDIs and other format give a try to Muse Sequencer:
 

 

linux-desktop:~$ sudo apt-get install –yes muse

The following NEW packages will be installed:

5. Some examples for Text editing and MIDI Conversion to CSV and ABC file formats There is pretty much more

For the MIDI Extremists who or people that create MIDIs and want to learn how a MIDI is made (the content of it etc.), I suggest you take a look at these 3 command line MIDI editing / conversion tools
 

  • midi2abc – A little tool to create MIDI formats to ABC format
  • midi2csv – Conver tour Favourite MIDI files to CSV for educational purposes so see what Channels, Tracks and Time Intervals is a MIDI song mad
  • midicopy – Copy selected, track, channel, time interval of MIDI file to another MIDI file3

 

Well, that's all folks now enjoy your MIDIs and don't forget to donate, as I'm jobless at the moment and the only profit I make is just a few bucks out of advertisement on this blog.

Disable graphical boot GRUB on Linux or how to boot Linux in true text mode

Saturday, September 30th, 2017

Is it possible to disable the graphical boot screen in Linux?

I have always loved to see the exact services that are loaded in Linux, during its boot.

I use Linux for 17 years already and I'm really used to see the status of Loaded services in Linux kernel boot from /etc/init.d/

Unfortunately since some time in all major Linux distributions for Desktop use  – the eb based, e.g. Debian, Ubuntu and RPM package system based – Fedora, OpenSUSE  Linux etc. that comes with GRUB2 boot loader pre-installed are configured by default to either show a static picture, or because of the faster boot times with the new systemd that replaced the old System V  to just show a blackscreen for a while during the actual processes being initialized quietly in the background.

Besides that if the Linux is to be installed on some Bare Metal Servers it is pretty much useless to have the Grub2 graphical boot enabled, so especially on Linux Servers Disabling Graphical Boot in GRUB is absolutely mandatory as on a servers debugging the boot process is an often task for the sysadmin.


Thanksfully for the curious people like me that want to see Boot loading statuses in order to see whether some service is improperly booted or there are some kind of warnings on boot, it is possible to:

DISABLE / TURN OFF GRAPHICAL BOOT IN LINUX


The way to disable graphical boot across both .deb and rpm – package based distributions is identical.

 

To disable graphical boot (enable text mode service status boot) mode in GRUB:


Become superuser (root) or use sudo (su wrapper) to edit /etc/default/grub 

 

vim /etc/default/grub

 

Find the line reading like:

 

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

 

quiet keyword tells GRUB to show little information about the boot process, while
splash option instructs GRUB2 to load the pre-configured Boot Picture showing up during the 5 seconds wait time in Grub Menu Screen, that requires us to choose the Kernel version or Advanced Options (Recovery, or other Kernel version to boot).

Change the value for GRUB_CMDLINE_LINUX_DEFAULT to be simply text, e.g.:

 

GRUB_CMDLINE_LINUX_DEFAULT="text"

 

Then to make GRUB loader reload the new configuration set run:

 

server:~# update-grub

 

Note that update-grub configuration reload command might be on a different location across various Linux distributions and generally it is a good practice to check with which command where exactly it is located and give a fullpath to the command, for example on Debian Linux, to give fullpath location.

 

# /usr/sbin/update-grub

Generating grub configuration file …
Found linux image: /boot/vmlinuz-4.9.0-3-amd64
Found initrd image: /boot/initrd.img-4.9.0-3-amd64
done

Well now restart PC / Server and enjoy, the text mode GRUB2 loader and the verbosity added to the boot process 😉

Transfer Contacts Nokia to Iphone 3GS, 5, 6, 7 mobile phone for free without using paid application using Nokia PC Suit VCF file export and Email or with Gmail / iCloud Contacts Synchronization

Sunday, September 24th, 2017

how-to-transfer-phone-contacts-from-old-nokia-symbian-phone-to-apple-iphone-ios-mobile

If you wonder how to transfer an old Nokia Mobile Contacts (with the already obsolete and unsupported "dumb" OS as well as the newer phones with Symbian – now abandoned mobile OS) and you need to transfer your contacts to iPhone (with iOS) easily, you can do that by backing up your Phone Contacts to a Windows 7,8, 10 PC and using the PC to transfer to Contacts to iPhone, either by email, through Google Mail Synchronization, (With Apple's iCloud) in case if you're using it, by importing to Outlook Express all the contacts once exported from Nokia Phone to PC and using iTunes to import to iPhone, or for the hardcore command line geeks to even use (WAB.EXE – Windows Address Book) command in conjunction with Apple iTunes to do the import.

Below described steps should be working on almost all Nokia mobile phones, such as Nokia 9300i, Nokia E, N, X and Nokia 6000, 7000, 8000 series as well, copying contacts from your Nokia to your iPhone Smart Phone works well across iPhone 3GS,4S,5, 6 and iPhone 7.

1. Backup Nokia Phone Contacts to Windows PC with Nokia PC Suite

Before proceeding with Nokia Contacts transfer to iPhone, make sure you create backup, just in case if something gets wrong, though this is not too likely it is always a good idea to take preventive measures, just to make sure your contacts doesn't disappear.

To backup your phone Contacts to ordinary PC with Windows, this is done via the good old Nokia PC Suite (Download it from here)

a. Install Nokia PC Suite run it and

b. connect your Nokia mobile phone with an USB Cable
, from the main menu choose Adress Book Icon, this is a small blue book icon in the Nokia PC Suite just like in the screenshot below:

c. A new window Nokia Communication Center will open Listing All Nokia phone existing contacts.

d. Go to the Windows PC to which you have just connected the Nokia Phone device and create somewhere lets say on Desktop (A new Windows folder called Nokia Contacts or whatever you like it to be called, we'll use this folder to transfer Nokia contacts there.

e.  Go back to Nokia Communication Center application, select a single contact (lets say the first one) and press CTRL + A to select all Nokia phone contacts

f. After selecting drag and drop selected contacts to just created Windows folder (Nokia Contacts)

That would output on your Windows PC under the folder all your Phone contacts in separete vCard format files (.VCF).

Now as we have all the Nokia Phone contacts stored each in a separate .VCF file in order to make the files easily importable, it is a very good idea to merge / combine all .VCF vCard files into a single .VCF vCard file.

So How to Merge All produced .VCF extension files into a single .VCF file?

Open Windows Command Prompt (Windows button + R) and type in (cmd.exe)

C:\Users\default>cd Desktop/"Nokkia Contacts"
C:Users\default> cp *.VCF ALL-Contacts.CVF

….

2. Import the Single .VCF Contacts file to Iphone by simply mailing it as attachment

The simplest way to import the just created above ALL-Contacts.VCF file is to simply mail it to yourself as an attachment, that works pretty well if your contacts list is not too big lets say 500-1000 contats, for really large contact lists, the Antivirus Software configured on mail servers might block the attachment, but in most cases just mailing the Single Merged .VCF file from the multiple .VCFs should be the best and easiest way to import Nokia Contacts without using a third party paid applications.

To import via email:

a. Send yourself email with the All-Contacts.VCF as attachment
b. Check your email with iPhone
c. Click on the attachment, once clicked iPhone will prompt you to import the CSV / .VCF Contacts, import them and you're done 🙂

3. Perhaps the easiest way (in case if you have a Gmail account) is to just import all just exported .VCF files into gmail, once all the contacts are now into Gmail, you can use iTunes to synchronize Gmail contacts to your iPhone.

http://www.leawo.com/knowledge/wp-content/uploads/2013/07/import-contacts-to-google-gmail

– Note that this method is a bad practise from security point of view as all your contacts will stay Synchronized into Gmail, well you have the option to delete them of course but still Google will have idea of which your contacts is, but anyways if you do it that way, once you have Phone contacts imported into Gmail:

port-contacts-to-google-email-gmail-screenshot-2how-to-import-contacts-to-google-email-gmail-screenshot-2

a) Launch iTunes on Win PC connect iPhone to the PC with USB data cable.

b) Select iPhone from iTunes under “Devices”, that is on the entry on the left sidebar of iTunes that will show the Summary page.

b) 5 Click "Info" tab on the right, and click "Sync Contacts with" checkbox,
– select "Google Contacts" from the drop-down menu
– click "Apply" or "Sync" button on the bottom-right corner of iTunes

4. Import .VCF files directly into ICloud (if you're using iCloud) I hope you don't as this completely compromises your security and stores data on separate servers somewhere in a Clustered storage

import-vcard-to-icloud-screenshot

a. To import VCF to iPhone 5/4S/4/3GS via iCloud,  make sure the "Contacts" option of the iCloud on your iPhone is turned on by checking in:

Settings -> iCloud -> turn “Contacts” on.
 

b. Go to www.icloud.com in a browser, log into your iCloud account with respetive Apple ID and password.
c. Click “Setting” button on the left corner and choose “Import vCard”
e To check the import is successful frm vCard files to iPhone, so go to your iPhone Address Book to check the contacts.

sync-icloud-with-iphone-contacts-howto-screenshot


Finally assuming that iCloud is enabled from within iPhone settings, make sure to turn off / turn on contacts synchronization to speed up the contacts transferred form iCloud to iPhone.

For the lazy ones who don't want to bother and just want to pay some cash and have the import painess, there is also paid softwares such as copytrans that can help you transfer contacts
 

Hope this helped someone out there,
For the rest Enjoy !

Finding top access IPs in Webserver or how to delay connects from Bots (Web Spiders) to your site to prevent connect Denial of Service

Friday, September 15th, 2017

analyze-log-files-most-visited-ips-and-find-and-stopwebsite-hammering-bot-spiders-neo-tux

If you're a sysadmin who has to deal with cracker attemps for DoS (Denial of Service) on single or multiple servers (clustered CDN or standalone) Apache Webservers, nomatter whether working for some web hosting company or just running your private run home brew web server its very useful thing to inspect Web Server log file (in Apache HTTPD case that's access.log).

Sometimes Web Server overloads and the follow up Danial of Service (DoS) affect is not caused by evil crackers (mistkenly often called hackers but by some data indexing Crawler Search Engine bots who are badly configured to aggressively crawl websites and hence causing high webserver loads flooding your servers with bad 404 or 400, 500 or other requests, just to give you an example of such obstructive bots.

1. Dealing with bad Search Indexer Bots (Spiders) with robots.txt

Just as I mentioned hackers word above I feel obliged to expose the badful lies the press and media spreading for years misconcepting in people's mind the word cracker (computer intruder) with a hacker, if you're one of those who mistakenly call security intruders hackers I recommend you read Dr. Richard Stallman's article On Hacking to get the proper understanding that hacker is an cheerful attitude of mind and spirit and a hacker could be anyone who has this kind of curious and playful mind out there. Very often hackers are computer professional, though many times they're skillful programmers, a hacker is tending to do things in a very undstandard and weird ways to make fun out of life but definitelely follow the rule of do no harm to the neighbor.

Well after the short lirical distraction above, let me continue;

Here is a short list of Search Index Crawler bots with very aggressive behaviour towards websites:

 

# mass download bots / mirroring utilities
1. webzip
2. webmirror
3. webcopy
4. netants
5. getright
6. wget
7. webcapture
8. libwww-perl
9. megaindex.ru
10. megaindex.com
11. Teleport / TeleportPro
12. Zeus
….

Note that some of the listed crawler bots are actually a mirroring clients tools (wget) etc., they're also included in the list of server hammering bots because often  websites are attempted to be mirrored by people who want to mirror content for the sake of good but perhaps these days more often mirror (duplicate) your content for the sake of stealing, this is called in Web language Content Stealing in SEO language.


I've found a very comprehensive list of Bad Bots to block on Mike's tech blog his website provided example of bad robots.txt file is mirrored as plain text file here

Below is the list of Bad Crawler Spiders taken from his site:

Crawl-delay: 20
# Begin Exclusion From Directories from robots.txt
Disallow: /cgi-bin/

Veryimportant variable among the ones passed by above robots.txt is
 

Crawl-Delay: 20

 


You might want to tune that variable a Crawl-Delay of 20 instructs all IP connects from any Web Spiders that are respecting robots.txt variables to delay crawling with 20 seconds between each and every connect client request, that is really useful for the Webserver as less connects means less CPU and Memory usage and less degraded performance put by aggressive bots crawling your site like crazy, requesting resources 10 times per second or so …

As you can conclude by the naming of some of the bots having them disabled would prevent your domain/s clients from Email harvesting Spiders and other not desired activities.


 

2. Listing IP addresses Hits / How many connects per IPs used to determine problematic server overloading a huge number of IPs connects

After saying few words about SE bots and I think it it is fair to also  mention here a number of commands, that helps the sysadmin to inspect Apache's access.log files.
Inspecting the log files regularly is really useful as the number of malicious Spider Bots and the Cracker users tends to be
raising with time, so having a good way to track the IPs that are stoning at your webserver and later prohibiting them softly to crawl either via robots.txt (not all of the Bots would respect that) or .htaccess file or as a last resort directly form firewall is really useful to know.
 

– Below command Generate a list of IPs showing how many times of the IPs connected the webserver (bear in mind that commands are designed log fields order as given by most GNU / Linux distribution + Apache default logging configuration;

 

webhosting-server:~# cd /var/log/apache2 webhosting-server:/var/log/apache2# cat access.log| awk '{print $1}' | sort | uniq -c |sort -n


Below command provides statistics info based on whole access.log file records, sometimes you will need to have analyzed just a chunk of the webserver log, lets say last 12000 IP connects, here is how:
 

webhosting-server:~# cd /var/log/apache2 webhosting-server:/var/log/apache2# tail -n 12000 access.log| awk '{print $1}' | sort | uniq -c |sort -n


You can combine above basic bash shell parser commands with the watch command to have a top like refresh statistics every few updated refreshing IP statistics of most active customers on your websites.

Here is an example:

 

webhosting-server:~# watch "cat access.log| awk '{print $1}' | sort | uniq -c |sort -n";

 


Once you have the top connect IPs if you have a some IP connecting with lets say 8000-10000 thousand times in a really short interval of time 20-30 minues or so. Hence it is a good idea to investigate further where is this IP originating from and if it is some malicious Denial of Service, filter it out either in Firewall (with iptables rules) or ask your ISP or webhosting to do you a favour and drop all the incoming traffic from that IP.

Here is how to investigate a bit more about a server stoner IP;
Lets assume that you found IP: 176.9.50.244 to be having too many connects to your webserver:
 

webhosting-server:~# grep -i 176.9.50.244 /var/log/apache2/access.log|tail -n 1
176.9.50.244 – – [12/Sep/2017:07:42:13 +0300] "GET / HTTP/1.1" 403 371 "-" "Mozilla/5.0 (compatible; MegaIndex.ru/2.0; +http://megaindex.com/crawler)"

 

webhosting-server:~# host 176.9.50.244
244.50.9.176.in-addr.arpa domain name pointer static.244.50.9.176.clients.your-server.de.

 

webhosting-server:~# whois 176.9.50.244|less

 

The outout you will get would be something like:

% This is the RIPE Database query service.

3. Generate list of directories and files that are most called by clients
 

webhosting-server:~# cd /var/log/apache2; webhosting-server:/var/log/apache2# awk '{print $7}' access.log|cut -d? -f1|sort|uniq -c|sort -nk1|tail -n10

( take in consideration that this info is provided only on current records from /var/log/apache2/ and is short term for long term statistics you have to merge all existing gzipped /var/log/apache2/access.log.*.gz )

To merge all the old gzipped files into one single file and later use above shown command to analyize run:

 

cd /var/log/apache2/
cp -rpf *access.log*.gz apache-gzipped/
cd apache-gzipped
for i in $(ls -1 *access*.log.*.gz); do gzip -d $i; done
rm -f *.log.gz;
for i in $(ls -1 *|grep -v access_log_complete); do cat $i >> access_log_complete; done


Though the accent of above article is Apache Webserver log analyzing, the given command examples can easily be recrafted to work properly on other Web Servers LigHTTPD, Nginx etc.

Above commands are about to put a higher load to your server during execution, so on busy servers it is a better idea, to first go and synchronize the access.log files to another less loaded servers in most small and midsized companies this is being done by a periodic synchronization of the logs to the log server used usually only to store log various files and later used to do various analysis our run analyse software such as Awstats, Webalizer, Piwik, Go Access etc.

Worthy to mention one great text console must have Apache tool that should be mentioned to analyze in real time for the lazy ones to type so much is Apache-top but those script will be not installed on most webhosting servers and VPS-es, so if you don't happen to own a self-hosted dedicated server / have webhosting company etc. – (have root admin access on server), but have an ordinary server account you can use above commands to get an overall picture of abusive webserver IPs.

Things to install on newly installed GNU / Linux (My favourite must have Linux text and GUI programs missing in fresh Linux installs)

Thursday, September 7th, 2017

must-have-packages-to-install-on-a-freshly-brand-new-linux-installed-on-desktop-computer-gnu-linux-logo

On every next computer I use as a Desktop or Laptop, I install with Debian GNU / Linux I install the following bunch of extra packages in order to turn the computer into a powerful Multimedia, User, Sys Admin army knife tools, A Programmer desktop and Hacker / Penetration Testing security auditting station.

The packages names might vary less or more across various Debian releases and should be similar or the same in Ubuntu / Linux Mint and the rest of Deb based distribtuions.

Also some of the package names might given in the article might change from time of writting this article just like some  already changed in time from a release to release, nomatter that the general list is a collection of packages I have enjoyed for the last 8 years. And I believe anyone who is new to GNU / Linux and  or even some experienced free software users in need of  full featured computer system for remote system administration purposes or general software development and even small entertainment such as Movie Watching or Playing some unsophisticated basic games to kill some time might benefit from the list of programs collected from my experience as a Free Software GNU / Linux users over the last 12 years or so.

So here we go as you might know, once you have a Debian GNU / Linux, first thing to do is to add some extra repositories in /etc/apt/sources.list

For example my debian 9 Stretch sources.list looks like this:

cp -rpf /etc/apt/sources.list /etc/apt/sources.list-bak

vim /etc/apt/sources.list

And delete / substitute everything within with something as following:

deb http://deb.debian.org/debian stretch main non-free
deb-src http://deb.debian.org/debian stretch main

deb http://deb.debian.org/debian stretch-updates main
deb-src http://deb.debian.org/debian stretch-updates main

deb http://security.debian.org/ stretch/updates main
deb-src http://security.debian.org/ stretch/updates main

deb http://security.debian.org/debian-security stretch/updates main contrib
deb-src http://security.debian.org/debian-security stretch/updates main contrib

deb http://download.virtualbox.org/virtualbox/debian stretch contrib

If you're using an older Debian release for example debian 7 or 8, the sources.list codename stretch word should be changed to wheezy for legacy debian 7 or jessie for debian 8, do it respectively for any future or older Deb releases.

Then proceed and update all current installed packages to their latest release with:
