kvm_virtualization-logo-redhat-8.3-install-howto-with-kickstart

If you don't have tried it yet Redhat and CentOS and other RPM based Linux operationg systems that use anaconda installer is generating a kickstart file after being installed under /root/{anaconda-ks.cfg,initial-setup- ks.cfg,original-ks.cfg} immediately after the OS installation completes. Using this Kickstart file template you can automate installation of Redhat installation with exactly the same configuration as many times as you like by directly loading your /root/original-ks.cfg file in RHEL installer.

Here is the official description of Kickstart files from Redhat:

"The Red Hat Enterprise Linux installation process automatically writes a Kickstart file that contains the settings for the installed system. This file is always saved as /root/anaconda-ks.cfg. You may use this file to repeat the installation with identical settings, or modify copies to specify settings for other systems."


Kickstart files contain answers to all questions normally asked by the text / graphical installation program, such as what time zone you want the system to use, how the drives should be partitioned, or which packages should be installed. Providing a prepared Kickstart file when the installation begins therefore allows you to perform the installation automatically, without need for any intervention from the user. This is especially useful when deploying Redhat based distro (RHEL / CentOS / Fedora …) on a large number of systems at once and in general pretty useful if you're into the field of so called "DevOps" system administration and you need to provision a certain set of OS to a multitude of physical servers or create or recreate easily virtual machines with a certain set of configuration.
 

1. Create /vmprivate storage directory where Virtual machines will reside

First step on the Hypervisor host which will hold the future created virtual machines is to create location where it will be created:

[root@redhat ~]#  lvcreate –size 140G –name vmprivate vg00
[root@redhat ~]#  mkfs.ext4 -j -b 4096 /dev/mapper/vg00-vmprivate
[root@redhat ~]# mount /dev/mapper/vg00-vmprivate /vmprivate

To view what is the situation with Logical Volumes and  VG group names:

[root@redhat ~]# vgdisplay -v|grep -i vmprivate -A7 -B7
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  – currently set to     8192
  Block device           253:0

 

  — Logical volume —
  LV Path                /dev/vg00/vmprivate
  LV Name                vmprivate
  VG Name                vg00
  LV UUID                VVUgsf-FXq2-TsMJ-QPLw-7lGb-Dq5m-3J9XJJ
  LV Write Access        read/write
  LV Creation host, time lpgblu01f.ffm.de.int.atosorigin.com, 2021-01-20 17:26:11 +0100
  LV Status              available
  # open                 1
  LV Size                150.00 GiB


Note that you'll need to have the size physically available on a SAS / SSD Hard Drive physically connected to Hypervisor Host.

To make the changes Virtual Machines storage location directory permanently mounted add to /etc/fstab

/dev/mapper/vg00-vmprivate  /vmprivate              ext4    defaults,nodev,nosuid 1 2

[root@redhat ~]# echo '/dev/mapper/vg00-vmprivate  /vmprivate              ext4    defaults,nodev,nosuid 1 2' >> /etc/fstab

 

2. Second we need to install the following set of RPM packages on the Hypervisor Hardware host

[root@redhat ~]# yum install qemu-kvm qemu-img libvirt virt-install libvirt-client virt-manager libguestfs-tools virt-install virt-top -y

3. Enable libvirtd on the host

[root@redhat ~]#  lsmod | grep -i kvm
[root@redhat ~]#  systemctl enable libvirtd

4. Configure network bridging br0 interface on Hypervisor


In /etc/sysconfig/network-scripts/ifcfg-eth0 you need to include:

NM_CONTROLED=NO

Next use nmcli redhat configurator to create the bridge (you can use ip command instead) but since the tool is the redhat way to do it lets do it their way ..

[root@redhat ~]# nmcli connection delete eno3
[root@redhat ~]# nmcli connection add type bridge autoconnect yes con-name br0 ifname br0
[root@redhat ~]# nmcli connection modify br0 ipv4.addresses 10.80.51.16/26 ipv4.method manual
[root@redhat ~]# nmcli connection modify br0 ipv4.gateway 10.80.51.1
[root@redhat ~]# nmcli connection modify br0 ipv4.dns 172.20.88.2
[root@redhat ~]# nmcli connection add type bridge-slave autoconnect yes con-name eno3 ifname eno3 master br0
[root@redhat ~]# nmcli connection up br0

5. Prepare a working kickstart.cfg file for VM


Below is a sample kickstart file I've used to build a working fully functional Virtual Machine with Red Hat Enterprise Linux 8.3 (Ootpa) .

# Disable kdump

%end

Important note to make here is the MD5 set root password string in (rootpw) line this string can be generated with openssl or mkpasswd commands :

Method 1: use openssl cmd to generate (md5, sha256, sha512) encrypted pass string

[root@redhat ~]# openssl passwd -6 -salt xyz test
$6$xyz$rjarwc/BNZWcH6B31aAXWo1942.i7rCX5AT/oxALL5gCznYVGKh6nycQVZiHDVbnbu0BsQyPfBgqYveKcCgOE0

Note: passing -1 will generate an MD5 password, -5 a SHA256 encryption and -6 SHA512 encrypted string (logically recommended for better security)

Method 2: (md5, sha256, sha512)

[root@redhat ~]# mkpasswd –method=SHA-512 –stdin

The option –method accepts md5, sha-256 and sha-512
Theoretically there is also a kickstart file generator web interface on Redhat's site here however I never used it myself but instead use above kickstart.cfg
 

6. Install the new VM with virt-install cmd


Roll the new preconfigured VM based on above ks template file use some kind of one liner command line  like below:
 

[root@redhat ~]# virt-install -n RHEL8_3-VirtualMachine –description "CentOS 8.3 Virtual Machine" –os-type=Linux –os-variant=rhel8.3 –ram=8192 –vcpus=8 –location=/vmprivate/rhel-server-8.3-x86_64-dvd.iso –disk path=/vmprivate/RHEL8_3-VirtualMachine.img,bus=virtio,size=70 –graphics none –initrd-inject=/root/kickstart.cfg –extra-args "console=ttyS0 ks=file:/kickstart.cfg"

7. Use a tiny shell script to automate VM creation


For some clarity and better automation in case you plan to repeat VM creation you can prepare a tiny bash shell script:
 

#!/bin/sh
KS_FILE='kickstart.cfg';
VM_NAME='RHEL8_3-VirtualMachine';
VM_DESCR='CentOS 8.3 Virtual Machine';
RAM='8192';
CPUS='8';
# size is in Gigabytes
VM_IMG_SIZE='140';
ISO_LOCATION='/vmprivate/rhel-server-8.3-x86_64-dvd.iso';
VM_IMG_FILE_LOC='/vmprivate/RHEL8_3-VirtualMachine.img';

virt-install -n "$VMNAME" –description "$VM_DESCR" –os-type=Linux –os-variant=rhel8.3 –ram=8192 –vcpus=8 –location="$ISO_LOCATION" –disk path=$VM_IMG_FILE,bus=virtio,size=$IMG_VM_SIZE –graphics none –initrd-inject=/root/$KS_FILE –extra-args "console=ttyS0 ks=file:/$KS_FILE"


A copy of virt-install.sh script can be downloaded here

Wait for the installation to finish it should be visualized and if all installation is smooth you should get a login prompt use the password generated with openssl tool and test to login, then disconnect from the machine by pressing CTRL + ] and try to login via TTY with

[root@redhat ~]# virst list –all
 Id   Name        State
—————————
 2    
RHEL8_3-VirtualMachine   running

[root@redhat ~]#  virsh console RHEL8_3-VirtualMachine


redhat8-login-prompt

One last thing I recommend you check the official documentation on Kickstart2 from CentOS official website

In case if you later need to destroy the VM and the respective created Image file you can do it with:
 

[root@redhat ~]#  virsh destroy RHEL8_3-VirtualMachine
[root@redhat ~]#  virsh undefine RHEL8_3-VirtualMachine

Don't forget to celebreate the success and give this nice article a credit by sharing this nice tutorial with a friend or by placing a link to it from your blog 🙂

Linux: Howto Disable logging for all VirtualHosts on Apache and NGINX Webservers one liner

Wednesday, July 1st, 2020

disable-apache-nginx-logging-for-all-virtualhosts
Did you happen to administer Apache Webservers or NGINX webservers whose logs start to grow so rapidly that are flooding the disk too quickly?
Well this happens sometimes and it also happens that sometimes you just want to stop logging especially, to offload disk writting.

There is an easy way to disable logging for requests and errors (access_log and error_log usually residing under /var/log/httpd or /var/log/nginx ) for  all configured Virtual Domains with a short one liner, here is how.

Before you start  Create backup of /etc/apache2/sites-enabled / or /etc/nginx to be able to revert back to original config.

# cp -rpf /etc/apache2/sites-enabled/ ~/

# cp -rpf /etc/nginx/ ~/


1. Disable Logging for All  Virtual Domains configured for Apache Webserver

First lets print what the command will do to make sure we don't mess something

# find /home/hipo/sites-enabled/* -exec echo sed -i 's/#*[Cc]ustom[Ll]og/#CustomLog/g' {} \;


You will get some output like

find /home/hipo//sites-enabled/* -exec echo sed -i 's/#*[Cc]ustom[Ll]og/#CustomLog/g' {} \;

find /etc/apache2/sites-enabled/* -exec sed -i 's/#*[Cc]ustom[Ll]og/#CustomLog/g' {} \;
find /etc/apache2/sites-enabled/* -exec sed -i 's/#*[Ee]rror[Ll]og/#ErrorLog/g' {} \;

2. Disable Logging for All configured Virtual Domains for NGINX Webserver
 

find /etc/nginx/sites-enabled/* -exec sed -i 's/#*access_log/#access_log/g' {} \;
find /etc/nginx/sites-enabled/* -exec sed -i 's/#*error_log/#error_log/g' {} \;

f course above substituations that will comment out with '#' occurances from file configs of only default set access_log and error_log / access.log, error.log 
for machines where there is no certain convention on file naming and there are multiple domains in custom produced named log files this won't work.

This one liner was inspired from a friend's daily Martin Petrov. Martin blogged initially about this nice tip for those reading Cyrillic check out mpetrov.net, so. Thanks Marto ! 🙂

IBM TSM dsmc console client use for listing configured backups, checking set scheduled backups and backup and restore operations howto

Friday, March 6th, 2020

tsm-ibm-logo_tivoli-dsmc-console-client-listing-backups-create-backups-and-restore-on-linux-unix-windows

Creating a simple home based backup solution with some shell scripting and rsync is a common use. However as a sysadmin in a middle sized or large corporations most companies use some professional backup service such as IBM Tivoli Storage Manager TSM – recently IBM changed the name of the product to IBM Spectrum.

IBM TSM  is a data protection platform that gives enterprises a single point of control and administration for backup and recovery that is used for Privare Clouds backup and other high end solutions where data criticality is top.
Usually in large companies TSM backup handling is managed by a separate team or teams as managing a large TSM infrastructure is quite a complex task, however my experience as a sysadmin show me that even if you don't have too much of indepth into tsm it is very useful to know how to manage at least basic Incremental backup operations such as view what is set to be backupped, set-up a new directory structure for backup, check the backup schedule configured, check what files are included and which excluded from the backup store etc. 

TSM has multi OS support ans you can use it on most streamline Operating systems Windows / Mac OS X and Linux in this specific article I'll be talking concretely about backing up data with tsm on Linux, tivoli can be theoretically brought up even on FreeBSD machines via the Linuxemu BSD module and the 64-Bit Tivoli Storage Manager RPMs.
Therefore in this small article I'll try to give few useful operations for the novice admin that stumbles on tsm backupped server that needs some small maintenance.
 

1. Starting up the dsmc command line client

 

Nomatter the operating system on which you run it to run the client run:

# dsmc

 

tsm-check-backup-schedule-set-time

Note that usually dsmc should run as superuser so if you try to run it via a normal non-root user you will get an error message like:

 

[ user@linux ~]$ dsmc
ANS1398E Initialization functions cannot open one of the Tivoli Storage Manager logs or a related file: /var/tsm/dsmerror.log. errno = 13, Permission denied

 

Tivoli SM has an extensive help so to get the use basics, type help
 

tsm> help
1.0 New for IBM Tivoli Storage Manager Version 6.4
2.0 Using commands
  2.1 Start and end a client command session
    2.1.1 Process commands in batch mode
    2.1.2 Process commands in interactive mode
  2.2 Enter client command names, options, and parameters
    2.2.1 Command name
    2.2.2 Options
    2.2.3 Parameters
    2.2.4 File specification syntax
  2.3 Wildcard characters
  2.4 Client commands reference
  2.5 Archive
  2.6 Archive FastBack

Enter 'q' to exit help, 't' to display the table of contents,
press enter or 'd' to scroll down, 'u' to scroll up or
enter a help topic section number, message number, option name,
command name, or command and subcommand:    

 

2. Listing files listed for backups

 

A note to make here is as in most corporate products tsm supports command aliases so any command supported described in the help like query, could be
abbreviated with its first letters only, e.g. query filespace tsm cmd can be abbreviated as

tsm> q fi

Commands can be run non-interactive mode also so if you want the output of q fi you can straight use:

tsm> dsmc q fi

 

tsm-check-included-excluded-files-q-file-if-backupped-list-backup-set-directories

This shows the directories and files that are set for backup creation with Tivoli.

 

3. Getting included and excluded backup set files

 

It is useful to know what are the exact excluded files from tsm set backup this is done with query inclexcl

tsm-check-excluded-included-files

 

4. Querying for backup schedule time

Tivoli as every other backup solution is creating its set to backup files in a certain time slot periods. 
To find out what is the time slot for backup creation use;

tsm> q sched
Schedule Name: WEEKLY_ITSERV
      Description: ITSERV weekly incremental backup
   Schedule Style: Classic
           Action: Incremental
          Options: 
          Objects: 
         Priority: 5
   Next Execution: 180 Hours and 35 Minutes
         Duration: 15 Minutes
           Period: 1 Week  
      Day of Week: Wednesday
            Month:
     Day of Month:
    Week of Month:
           Expire: Never  

 

tsm-query-partitions-backupeed-or-not

 

5. Check which files have been backed up

If you want to make sure backups are really created it is a good to check, which files from the selected backup files have already
a working backup copy.

This is done with query backup like so:

tsm> q ba /home/*

 

tsm-dsmc-query-user-home-for-backups

If you want to query all the current files and directories backed up under a directory and all its subdirectories you need to add the -subdir=yes option as below:

 

tsm> q ba /home/hipo/projects/* -subdir=yes
   
Size      Backup Date        Mgmt Class A/I File
   —-      ———–        ———- — —-

 11,013  24-04-2012 00:22:56    STANDARD    A  /home/hipo/projects/hsm42upg/md5check  

 

  • To make tsm, backup some directories on Linux / AIX other unices:

 

tsm> incr /  /usr  /usr/local  /home /lib

 

  • For tsm to backup some standard netware drives, use:

 

tsm> incr NDS:  USR:  SYS:  APPS:  

 

  • To backup C:\ D:\ E:\ F:\ if TSM is running on Windows

 

tsm> incr C:  D:  E: F:  -incrbydate 

 

  • To back up entire disk volumes irrespective of whether files have changed since the last backup, use the selective command with a wildcard and -subdir=yes as below:

 

tsm> sel /*  /usr/*   /home/*  -su=yes   ** Unix/Linux

 

7. Backup selected files from a backup location

 

It is intuitive to think you can just add some wildcard characters to select what you want
to backup from a selected location but this is not so, if you try something like below
you will get an err.

 

tsm> incr /home/hipo/projects/*/* -su=yes      
ANS1071E Invalid domain name entered: '/home/hipo/projects/*/*'


The proper way to select a certain folder / file for backup is with:

 

tsm> sel /home/hipo/projects/*/* -su=yes

 

8. Restoring tsm data from backup

 

To restore the config httpd.conf to custom directory use:

 

tsm> rest /etc/httpd/conf/httpd.conf  /home/hipo/restore/

 

N!B! that in order for above to work you need to have the '/' trailing slash at the end.

If you want to restore a file under a different name:

 

tsm> rest /etc/ntpd.conf  /home/hipo/restore/

 

9. Restoring a whole backupped partition

 

tsm> rest /home/*  /tmp/restore/ -su=yes

 

This is using the Tivoli 'Restoring multiple files and directories', and the files to restore '*'
are kept till the one that was recovered (saying this in case if you accidently cancel the restore)

 

10. Restoring files with back date 

 

By default the restore function will restore the latest available backupped file, if you need
to recover a specific file, you need the '-inactive' '-pick' options.
The 'pick' interface is interactive so once listed you can select the exact file from the date
you want to restore.

General restore command syntax is:
 

tsm> restore [source-file] [destination-file]

 


tsm> rest /home/hipo/projects/*  /tmp/restore/ -su=yes  -inactive -pick

To navigate in pick interface you can select individual files to restore via the number seen leftside.
To scroll up / down use 'U' and 'D' as described in the legenda.

 

11. Restoring your data to another machine

 

In certain circumstances, it may be necessary to restore some, or all, of your data onto a machine other than the original from which it was backed up.

In ideal case the machine platform should be identical to that of the original machine. Where this is not possible or practical please note that restores are only possible for partition types that the operating system supports. Thus a restore of an NTFS partition to a Windows 9x machine with just FAT support may succeed but the file permissions will be lost.
TSM does not work fine with cross-platform backup / restore, so better do not try cross-platform restores.
 Trying to restore files onto a Windows machine that have previously been backed up with a non-Windows one. TSM created backups on Windows sent by other OS platforms can cause  backups to become inaccessible from the host system.

To restore your data to another machine you will need the TSM software installed on the target machine. Entries in Tivoli configuration files dsm.sys and/or dsm.opt need to be edited if the node that you are restoring from does not reside on the same server. Please see our help page section on TSM configuration files for their locations for your operating system. 

To access files from another machine you should then start the TSM client as below:

 

# dsmc -virtualnodename=RESTORE.MACHINE      


You will then be prompted for the TSM password for this machine.

 

You will probably want to restore to a different destination to the original files to prevent overwriting files on the local machine, as below:

 

  • Restore of D:\ Drive to D:\Restore ** Windows 

 

tsm> rest D:\*   D:\RESTORE\    -su=yes 
 

 

  • Restore user /home/* to /scratch on ** Mac, Unix/Linux

 

tsm> rest /home/* /scratch/     -su=yes  
 

 

  • Restoring Tivoli data on old netware

 

tsm> rest SOURCE-SERVER\USR:*  USR:restore/   -su=yes  ** Netware

 

12. Adding more directories for incremental backup / Check whether TSM backup was done correctly?

The easiest way is to check the produced dschmed.log if everything is okay there should be records in the log that Tivoli backup was scheduled in a some hours time
succesfully.
A normally produced backup scheduled in log should look something like:

 

14-03-2020 23:03:04 — SCHEDULEREC STATUS BEGIN
14-03-2020 23:03:04 Total number of objects inspected:   91,497

in case of errors you should check dsmerror.log
 

Conclusion


In this article I've briefly evaluated some basics of IBM Commercial Tivoli Storage Manager (TSM) to be able to  list backups, check backup schedules and how to the files set to be
excluded from a backup location and most importantly how to check that data backed up data is in a good shape and accessible.
It was explained how backups can be restored on a local and remote machine as well as how to  append new files to be set for backup on next incremental scheduled backup.
It was shown how the pick interactive cli interface could be used to restore files at a certain data back in time as well as how full partitions can be restored and how some
certain file could be retrieved from the TSM data copy.

A quick and easy way to install Social Network on Linux/BSD System with Elgg

Monday, March 14th, 2011

elgg-blue-logo
I'm experimenting this days with Elgg – An Open Source Free Software GPLed Social Network which enables users to quickly create Communities.

Elgg is really easy to install and all it requires is a Linux/BSD or Windows system with PHP, MySQL and Apache installed.

Elgg is provided with dozens of nice plugins which for a short time enables individual to create fully operational Social Network like facebook.

Many people nowdays use facebook without realizing how bad facebook is how it breaks their privacy.
Facebook is actually a spy network, it stores data and pictures, likings and user behaviour of million of users around the world.
This needs to be stopped somehow, maybe if people start using the free software networks like elgg to build a mini-community which has profound interests in a certain spheres of work, life and amusement.
The evil empire of facebook will slowly start to loose it's position and the small projects networks based on Elgg and the other Free Software Social Networks which are currently available will start to rise up.
I'm currently really a novice into Elgg but I'm more convinced that the guys who develop it and contribute to it in terms of handy plugins have done really a great job.

It's ultra easy even for non professional middle level user to setup himself an Elgg install.
The installation procedure is not much harder than a simple wordpress blog or joomla based website install.
The installation of elgg takes no more than 10 to 20 minutes, the plugin installation and setup time further could take few days but in the end you have a full featured Social Network! This is really amazing.
The installation of new plugins in elgg is also fool proof / easy all you have to do to equip a newly installed elgg with plugins is to go to it's root directory and look for the mod directory. The new plugins which needs to be installed, could be directly downloaded and saved via links, elinks, lynx or even wget to the elgg installation directory.

Most of the elgg plugins comes in a form of zip files so after being installed simply executing:

server:/home/elgg/mysocialnetwork/mod# unzip walltowall.zip
....

The above cmd will for example unzip the WallToWall elgg plugin and the plugin will be further ready to be enabled via the administrator user set upped during your elgg installation.

The configurations of elgg are being accomplished via:

Administration -> Tool Administration

I should I'm still experimenting with Elgg social, until this very moment I've installed the following elgg plugins:

zaudio

One very handy feature I truly enjoy about Elgg is that it gives every user an own blog which or in other words when somebody registers in Elgg, he automatically gets a personal blog! How cool this is Yeash 😉
The Elgg photo upload plugin is also another interesting story. The photo plugin is a way better from my first impressions than facebook's buggy upload client.
Elgg also uses heavily jquery for it's various operations and the user experience feels very interactive.

Of course as with all free software things are not perfect some of the elgg plugins or (mods) as they are called are not working.
For example I couldn't make by so far the weather plugin which is supposed to report the weather.

Maybe some tweakening of the not working plugins will easily make them working. What is really important is that the Elgg basis system looks and seems to work really good and enpowers the user with a social network alternatives to the ugly facebook.

In order to experiment with Elgg and I've established a small social network targetting at University College and School Students called MockATeacher – mockateacher.com>/i>. The idea behind is to help students in their report writting by providing them with a place where they can meet other students and share files.

Some other aspects I've planned for MockATeacher is to build a small community of people who would like to share about idiot teachers, teacher stupid sayings as well as to mock the idiotic type of education that we and our children are up to in this age.
Just to close up, if you're looking for some time to spend in experimenting in an enjoyable way you definitely need to install elgg and play with it 😉

DOOM 1, DOOM 2, DOOM 3 game wad files for download / Playing Doom on Debian Linux via FreeDoom open source doom engine

Thursday, March 24th, 2011

Doom 2 game screenshot

Every now and then as an ex-gamer I do remember the good glorious times of the DooM oldschool 3d shooter game.

As a Linux user I do have the option to play Doom 1 and Doom 2 straight using the GPLed version of the game called FreeDoom

FreeDoom comes with a custom wad file called freedoom.wad which is a considerably good remake of the doom game, but still I don't find so funny and bringing memories as the original game.

Thus in order to experience the original doom game play, levels and sound on my Linux, I need to use the original doom wad files

The DooM original wad files are already an abandonware and nowdays it's a bit hard to be found. Still the wad files for the games are available for download on some major torrent trackers like piratebay but it takes time to find them therefore I decided to publicly share the Doom 1, Doom 2 and Doom 3 wad files to be easier for me to later put and play them on Linux and BSD operating systems, on the other hand I do think this files might be useful for many other oldschool DooM fans out there.

Here are the files for download:

1. Download doom 1, doom 2 and doom 3 wad files + extra of plutonia wad and tnt wad rar archive

2. Download Doom1.wad file
3. Download Doom2.wad file
4. Download Doom3.wad file

(Note that this is not original Doom3.wad – For free, its custom doom wad for prboom engine!!!)
5. Download Doom Plutonia.wad
6. Download Doom Tnt.wad

On my Debian Linux with the freedoom package in order to play the Doom1 or Doom2 wad files it's necessary to download and place the doom1.wad or doom2.wad files into the directory /usr/share/games/doom

It's important that the WAD files names does not contain capital letters (e.g. the files need to be placed with file names doom1.wad and doom2.wad)

The FreeDoom port package in Debian Lenny and Squeeze is available to be installed easily through apt like so:

debian:~# apt-get install prboom freedoom

To start up the doom2 game, issue the command:

debian:~# prboom

prboom also allows you to select a custom .wad file you want to play, for a custom wad file you can invoke the command:

debian:~# prboom -file yourwadfilename


UPDATE: A bonus you might seriously Enjoy, if you happen to be DooM 2 game fan / addict is an Awesome MIDIS Soundtrack by Bobby Prince you can download it song by song in midi format here or if you prefer download the whole doom 2 Bobby Prince midi songs archive
Enjoy the nice oldschool game 😉

How to Remove / Add SuSE Linux start service command

Thursday, July 2nd, 2015

opensuse-remove-add-new-service-geeko-suse-linux-mini-logo
If you happen to administer SUSE LINUX Enterprise Server 9 (x86_64) and you need to add or remove already existing /etc/init.d script or custom created Apache / Tomcat .. etc. service and you're already familiar with Fedora's / RHEL chkconfig, then the good news chkconfig is also available on SuSE and you can use in same way chkconfig to start / stop / enable / disable boot time services.

To list all available boot time init.d services use:
 

suse-linux:/etc # chkconfig –list

To then stop the service:
 

suse-linux:/etc # chkconfig gtiweb off


If you prefer to do it the SuSE way and learn a bit more on SuSE boot time process check out:

 

suse-linux:/etc # man insserv


Removing already existing SuSE start-up script from init.d start up with insserv is done with:

suse-linux:/etc # cd /etc/init.d/
suse-linux:etc/init.d # insserv -r gtiweb
insserv: script ipmi.hp: service ipmidrv already provided!
insserv: script boot.multipath.2008-10-29: service boot.multipath already provided!


To install a new custom written and placed into /etc/inti.d/ on SuSE's server boot time with insserv:

 

suse-linux:/etc/init.d/ # insserv your_custom_script_name

How to add (.srt , .sub) subtitles to .flv flash movie video on Linux

Friday, April 15th, 2011

how-to-add-srt-subtitles-to-flv-flash-movie-video-on-linux
If you're on Linux the questions like, how can I convert between video and audio formats, how to do photo editing etc. etc. have always been a taugh question as with it's diversity Linux often allows too many ways to do the same things.

In the spirit of questioning I have been recently curious, how can a subtitles be added to a flash video (.flv) video?

After some research online I've come up with the below suggested solution which uses mplayer to do the flash inclusion of the subtitles file.

mplayer your_flash_movie.flv -fs -subfont-text-scale 3

While including the subtitles to the .flv file, it's best to close up all the active browsers and if running something else on the desktop close it up.
Note that above's mplayer example for (.srt and .sub) subtitle files example is only appropriate for a .flv movie files which already has a third party published subtitle files.

What is interesting is that often if you want to make custom subtitles to let's say a video downloaded from Youtube on Linux the mplayer way pointed above will be useless. Why?

Well the Linux programs that allows a user to add custom subtitles to a movie does not support the flv (flash video) file format.

My idea on how to create custom subtitles and embed them into a flv movie file is very simple and it goes like this:

1. Convert the .flv file format to let's say .avi or .mpeg
2. Use gnome-subitles or subtitleeditor to create the subtitles for the .avi or .mpeg file
3. Convert back the .avi/.mpeg file with included subtitles to .flv (flash video format)

This methodology is really long and time consuming, but pitily as far as my understanding goes it's the only way to do that on your Linux until now.

To make the conversations between .flv and .avi format you will need to use the ffmpeg – (FFMpeg command line tool video converter), here is how:

– Convert .flv to .avi

debian:~# /usr/bin/ffmpeg -i input_flvfilename.flv output_avifilename.avi

– Convert .avi file to .flv

debian:~# /usr/bin/ffmpeg -y -i /path/to/your/avi/input_avifilename.avi -acodec mp3 -ar 22050 -f flv
/path/to/your/flv/output_flvfilename.flv

The required overall tools which you will have to have installed on your Debian or Ubuntu Linux are:

1. ffmpeg
2. gnome-subtitles
3. subtitleeditor
4. mplayer

You will also have to spend some time to get to know gnome-subtitles or subtitleeditor, but it won't be that long until you get the idea on how to use them.

Make custom installed Mozilla Firefox restore tab sessions on Debian GNU / Linux

How to make custom installed Firefox restore tabs on browser close up - firefox restore website windows sessions

As my blog readers might, know I'm running Debian Squeeze on my notebook as a Desktop OS. Until some time I used to be a big fan of Epiphany but lately I started not using Epiphany so much because of its too frequent crashes while browsing a website that contains Flash. The problem of course is not in Epiphany itself but in the flash but still, as this is really disturbing if someone works, I nowdays use only Firefox. I tried for a while to use IceWeasel, but IceWeasel (Firefox) version is too old:

hipo@noah:~$ iceweasel –version
Mozilla Iceweasel 3.5.17, Copyright (c) 1998 – 2011 mozilla.org

Thus I use a custom download binary release from Firefox's website the one distributed as of time of writing post in archive firefox-16.0.2.tar.bz2

One of main advantages of installing the custom binary from Firefox, website is it auto updates and I'm always running the latest Release on myLinux Desktop, something IceWeasel still doesn't.

My current firefox version is:

hipo@noah:/opt/firefox$ /opt/firefox/firefox –version
Mozilla Firefox 16.0.2

All works fine with it, except two little things;

  • One is Firefox development team compiled the Browser to still use OSS and not the newer and used almost by all programs ALSA (Advanced Linux Sound Architecture) – something that is unfortunately irreversalble
     
  • Secondly  (which is the reason to write this) Firefox Linux version – doesn't by default Restore closed browser open tab websites! – e.g. session restore in those Firefox version is not working.

In Windows Firefox usually asks, while closing the whole browser, if the user wants to Save Browser Session, on the Linux version this is not default behavior, maybe developers have to answer why?

I was not sure if this would work but I went googling about a plugin to make Firefox Restore Sessions and tried installing first query matched FF plugin Session Manager

I was a bit sceptical that this would work

and actually just intalling the plugin didn't changed Firefox to save websites open in tabs on a close. After however I configured the plugin from FF menus:

Tools -> Session Manager -> Session Manager Options Tab restoration in Firefox worked

In below screnshot from Session Manager Options you can see my exact selected settings


Well that's all, finally I can remember what I had my browser before PC shutdown 🙂

Disabling PHP system(); and exec(); functions to raise up Apache security on Debian GNU / Linux

Wednesday, July 18th, 2012

Disabling PHP system(); and exec(); functions to raise up Apache security on Debian Gnu / Linux

At security critical hosts running Apache + PHP based sites it is recommended functions like:

system();
exec();shell_exec();.....

to be disabled. The reason is to mainly harden against script kiddies who might exploit your site/s and upload some shitty SK tool like PHP WebShell, PHP Shell and the probably thousands of “hacker” variations that exist nowdays.

In latest Debian stable Squeeze, suhosinadvanced protection module for php5 is being installed and enabled in Apache (by default).
Simply disabling a number of functions using suhosin, could prevent multiple of future headaches and hours of pondering on who 0wn3d your server ….

Disabling the basic PHP system(); and other similar functions which allows shell spawn is not always possible, since some websites or CMS platforms depends on them for proper runnig, anyways whether it is possible disabling ’em is a must.
There are two ways to disable system(); functions; One is through using /etc/php5/apache2/conf.d/suhosin.ini and 2nd by adding a list of functions that has to be disabled directly in Website Virtualhost file or in apache2.conf (/etc/apache2/apache2.conf;
For people hosting multiple virtualhost websites on the same server using the custom domain Virtualhost method is probably better, since on a global scale the functions could be enabled if some of the websites hosted on the server requires exec(); to work OK. In any case using /etc/php5/apache2/conf.d/suhosin.ini to disable system(); functions in PHP is less messy …

1. Disabling PHP system(); fuctions through /etc/apache2/apache2.conf and custom site Vhosts

Place somewhere (I prefer near the end of config);;;


php_admin_flag safe_mode on
php_admin_value disable_functions "system, exec, shell_exec, passthru , ini_alter, dl, pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen, escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version, apache_getenv, apache_note,apache_setenv,virtual"

Disabling it for custom virtualhost is done by simply adding above Apache directvies (before the closing tag in /etc/apache2/sites-enabled/custom-vhost.com

2. Disabling PHP system();, exec(); shell spawn with suhosin.ini

In /etc/php5/apache2/conf.d/suhosin.ini add;;

suhosin.executor.func.blacklist =system, exec, shell_exec, passthru, ini_alter, dl,
pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen,
escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version,
apache_getenv, apache_note,apache_setenv,virtual

To do it directly via shell issue;;;

server: conf.d/# cd /etc/php5/apache2/conf.d/
server: conf.d# echo 'suhosin.executor.func.blacklist =system, exec, shell_exec, passthru, ini_alter, dl,' >> suhosin.ini
server: conf.d# echo 'pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen,' >> suhosin.ini
server: conf.d# echo escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version,' >> suhosin.ini
server: conf.d# echo 'apache_getenv, apache_note,apache_setenv,virtual' >> suhosin.ini

Then to re-load the memory loaded Apache libphp library an Apache restart is necessary;

server: conf.d# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .
server: conf.d#

Tadam, this should be quite a good security against annoying automated script attacks. Cheers 😉

Three Ways to Reduce Addiction to Mobile Phone ( GSM ) use

Wednesday, June 27th, 2012

Mobile Phone Caricature Reduce Mobile Addiction / 3 ways to reduce mobile phone addiction / Use your Mobile less

1.: Don't use a ring tone or use a short landline phone ringtone on incoming calls

In the past, we all had a local stand line phones, most of the landline phones rung using a very specific ring sound which was almost identical on all phones around the world. This ringing tone used was following some telephone standards. The result was everyone could distinguish a ringing phone in a room or closed space and tell for sure, this sound is generated by a phone. Nowdays with the boom of cellular phone ringtones, there is almost noone who uses a standard old-fashioned telephone ringtone as a ring melody.

The consequence of this is in our minds we start loosing the boundary between whether communicating on the phone or communicating without it.
In younger people this boundary between phone line and a physical communication is more evident than in adults (as youngsters has grown in society where mobile was used everywhere). The implication of this is more and more people are starting to perceive mobile communication as so natural as the person to person communication. Spending big part of the day talking over the phone mostly senseless things, not being consciously aware that this is done due to a heavy phone addiction and repeating behaviour trait stored sub-consciously.

Today everyone chooses a custom mobile phone ringtone melody (popular or impopular) song and sets it up to be a standard incoming call signal. As you can guess there are consequences on the mind, as the ringtone set is heard ten times or more a day during each and every phone call. The result is just like with alcoholics or drug addicts, the more you take from a certain "good" the more attached you become to it. Hence the more we listen to a certain song chunk daily on incoming calls, the sub-conscious becomes dependent on hearing this sound at least a number of times daily. If a day passes without no-one calling us and we don't hear the ringtone indicating a call the sub-conscious stored dependency starts popping up and we could start feeling lonely and we feel like calling someone (and we often do). Obviously this is dependency and even if someone might argue me this is a severe addiction which as every other addiction could be very dangerous and hard to fight.

As I prior said due to the fact that the phone use dependency is built in our minds starting with the phone ring melody, we can reduce this dependency by switching off the phone ringtone completely or at least changing it to a unique beep which is not likely to be heard or seen somewhere in your surrounding environment.

By setting the ringtone to some popular song we see on (TV, Radio or Internet on daily basis) this might become a trigger for us to associate hearing this sound with talking on the phone and hence make you increase the time you spend on the phone ,,, so be careful ,,,,

2.:: Stop Mobile Beeps and sounds on menu navigation

All new mobiles sold on the market are configured to have buzzling sounds on events and various beeps on keypad lock / unlock and menu navigation.
This sounds are there mostly to make you more alert and concentrated on using your mobile and often as a consequence whether one uses his mobile his awareness is comletely taken by the phone screen (you're totally "absorbed" by the phone use).
Besides designed to alert you the Managers and CEO's who decided to have a heavy beep sounds on mobiles made it having probably something else on mind? The beeps on keypad navigation makes the user emotionally and sub-consciously attached to the Cell Phone. The idea here is like in popular music streamed on radios and TVs and mostly everywhere …. The more you listen to a song, the higher the mind trait it leaves in you, so later when one hears a music pattern or a whole song, which he / she listened already thousands of times this brings back "good" old memories. It is very simple actually our minds are constructed in a way that the mor certain "information" is heard / saw / smell the bigger the mind influence this leaves on us. Back to the mobile sounds, the more you use the mobile phone with turned on sounds, the more addicted and mind stucked the beep and melodies during use of the cell phone becomes in the mind. For example many people take a look at their mobile automatically (without being consciously aware) and do the activity of (unlock) and (lock) the phone screen not knowing they do it automatic. More or less we all do such an auto-mated learned behaviour because of the subconscious dependency that is built in our minds. Whether we lock and unlock the mobile phone almost robotically, we do it because our sub-conscious mind plays a trick on us and "force" us to do a previous learned activity (association in our mind with the unlock / lock beep sound).

3.::: Use your mobile in different ways

Any modern mobile is quite advanced in functionality and there is more than one way to initiate a phone call. E.g. the mobile has a shortcut buttons assigned to do quick phone calls, quickly evoke SMS menu etc.
Learn them and occasionally use the shortcut buttons instead of the menu navigation. Our minds like changing patterns and doing things different.

Even if you have no chance to do a things via a certain menu, you can always change the position of the phone screen to different distance to eyesight 🙂 You can for example type on the keypad following the menu steps by watching from left or right eye periphery or you can use the menus with your phone screen turned backwards 🙂 If you're used to type on the keypad or touch screen with right hand try doing it with the left hand 🙂

This will take time but the fun worths it. Plus the most valuable thing in using the mobile in different ways each time is there is no specific inflicting pattern associated in your mind and hence the depepdency set in your sub-conscious mind on phone use is lesser.
Actually there are too many various "hacks" one could come up with on how to use mobile as differently as possible. It is up to your imagination. Though using the mobile "each-time-different" can be sometimes more time-consuming it surely makes your phone use amusing.
