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

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
This is free software with ABSOLUTELY NO WARRANTY.
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/*

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:
  muse

Below is short description what Muse can do for you:

 

MusE is a MIDI/audio sequencer with recording and editing capabilities.
 Some Highlights:
 

  * Standard midifile (smf) import-/export.
  * Organizes songs in tracks and parts which you can arrange with
    the part editor.
  * MIDI editors: pianoroll, drum, list, controller.
  * Score editor with high quality postscript printer output.
  * Realtime: editing while playing.
  * Unlimited number of open editors.
  * Unlimited undo/redo.
  * Realtime and step-recording.
  * Multiple MIDI devices.
  * Unlimited number of tracks.
  * Sync to external devices: MTC/MMC, Midi Clock, Master/Slave.
  * Audio tracks, LADSPA host for master effects.
  * Multithreaded.
  * Uses raw MIDI devices.
  * XML project file.
  * Project file contains complete app state (session data).
  * Application spanning Cut/Paste Drag/Drop.

 

linux-desktop~:$ muse

muse-advanced-midi-editor-free-software-for-linux

 

Below is another non-free program that you might, try if MusE doesn't fit your needs (is not rich enough for editting capabilities is bitwig (though I don't recommend since it is not free software)

bitwig – Bitwig Studio is a multi-platform music-creation system for production, performance and DJing, with a focus on flexible editing tools and a super-fast workflow.

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.

Graphic tool to get Hardware Information on Linux / How to view Hardware Information easy in Linux

Tuesday, October 3rd, 2017

 

 

howto-get-graphically-system-hardware-info-linux-gui-program-for-hardware-recognition-linu

 

IS THERE A GRAPHIC ( GUI ) TOOL TO VIEW HARDWARE INFORMATION ON LINUX?

 


If you are a console maniac like myself, perhaps you never think that you might need anything graphical besides to view hardware information on Linux, but as we're growing older sometimes it becomes much less easier to just use a graphical tool that can show us all the information we need regarding a Notebook / Desktop PC with Linux or even Server machine with enabled Graphical Environment with a brand new installed GNU / Linux whatever version (I hope you don't own server with running Xorg / Gnome / Mate / Xfce etc. as that's pretty much a waste of hardware resource and opens a dozen of other security risks for the server running services ).

 

 

 There are at least 2 ways to quickly check hardware on both PC WorkStation or Server, the easiest and quickest for PC / Notebook Linux users if you have installed GTK libraries or Gnome Desktop Environment is with;
 

LSHW-GTK


LSHW-GTK is simply a GTK frontend over the command line tool for hardware information gathering LSHW
 

HardiInfo

 

HardInfo – is a small application that displays information about your hardware and operating system. Currently it knows about PCI, ISA PnP, USB, IDE, SCSI, Serial and parallel port devices.


1. Howto Install LSHW-GTK / HardInfo on Debian / Ubuntu / Mint GNU / Linux to easy view hardware information


To install both of them on Debian / Ubuntu GNU / Linux, run:
 

apt-get install –yes lshw lshw-gtk hardinfo

 

2. Howto install LSHW-GTK on Fedora, CentOS and OpenSuSE Linux to view easy hardware information

On RedHat RPM based Linux distributions, the package to install is called lshw-gui

Install with yum RPM package manager:
 

yum install –yes lshw lshw-gui  hardinfo


3. Run lshw-gtk / hardinfo

Again, find them and run from GUI environment menus or run manually like in below example:

$ lshw-gtk


graphic-program-to-view-computer-hardware-on-linux-lshw-gtk-on-debian-linux-screenshot-view-hardware-easy-linux1

 

$ hardinfo


hardinfo-a-gui-program-to-view-computer-hardware-info-on-linux-and-freebsd

As you see hardinfo is really interactive and it gives you pretty much all the information, you might need, the only information that was missing at my case and I guess, that would happen to others is information about the SSD Hard Disk, which   180GB

HardInfo is really amazing program as it even includes various common Benchmark Tests and comparison with other Computers:

hardinfo-get-hardware-information-easily-on-linux-and-freebsd-benchmark-info-screenshot-debian-stretch

True that the tests, are pretty simple but still could be useful.

Now run it either from GNOME / Cinnamon (The default graphical environment of Debian Linux) or PLASMA (The new name for the second most popular Linux Graphical Environment – KDE desktop environment)

 

$ lshw


Here is few more screenshots from hardware info reported from my ThinkPad T410 Laptop Running Debian 9 Stretch at the moment.

 

MotherBoard -> BIOS Information

(thatnks God this old but gold Thinkpad T420 business notebook does not run UEFI substitute for BIOS 🙂

CPU Information (with all the supported CPU capabilities (extensions)

By the way another Way to GUI View your Computer is to just generate HTML from lshw command line tool (as it supports export to HTML), here is how:

 

$ lshw -html > ~/hardware-specs.html


Then just open it with Browser, for example I like GNOME Epiphany browser, so I'll read HTML with it:

 

$ epiphany ~/hardware-specs.html


graphical-software-to-view-hardware-on-linux-lshw-command-to-generate-html-and-view-it-graphically-in-browser-on-home-pc-or-server


The great thing about generating HTML report for hardware is that on Staging / Production / Development servers which you inherited from some other administrator who for some reason (laziness 🙂 ) didn't left necessery documentation, you can easily map the machine hardware and even if it is a group of machines, you can automate report generation for all of them write a short script that parses the data on each of the HTML reports and finally creates a merged document with main important information about hardware of a cluster of computers etc.

If you still want to stick to console run the console version of lshw or use dmidecode or lshw:

 

$ lshw

hipo@jericho:~$ lshw

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:

apt-get update && apt-get upgrade

If you're running on a very old Debian GNU / Linux release , you might encounter errors from above cmds, if that's your case just follow the online guides and update to a newer still supported Deb release.

Once all this is done assuming you have connected to the internet via LAN network or if on a laptop via Wireless, here are some useful stuff to install especially if you're planning to use your computer effectively in both console and graphics environment.

 

1. Install some basic packages necessery if you're planning to be using compilers on the freshly installed GNU / linux

The most notable package here is build-essential it provides the following collection of C / C++ programs on Deb package based distributions Debian / Ubuntu / Mint etc.
 

  1. libc6-dev – C standard library.
  2. gcc – C compiler.
  3. g++ – C++ compiler.
  4. make – GNU make utility to maintain groups of programs.

There are probably a lot of more handy packages that other Free Software users like to install to make the GNU / Linux desktop notebook even more entertaining and fulfillful for daily work. If you can think of other useful packages not mentioned here you tend to use on a daily basis no matter where Debian based or other distro, please share that would help me too to learn a new thing and I'll be greateful.

Enjoy !

Linux: /var/log/wtmp – No such file or directory quick fix and why it might be missing on a server

Thursday, May 4th, 2017

fix-var-log-wtmp-btmp-no-such-file-or-directory-linux_last_command-howto-quick-fix

If you have to occasionally log  into some client old inherited (not installed by you) Linux servers on and just out of curiosity and for security sake dediced do a quick security (last user login) evaluation, e.g. issued the
last command just to find out you get the error:

last: /var/log/wtmp: No such file or directory

Perhaps this file was removed by the operator to prevent logging last info.

Then this might be a sure indicator that some malicious script kiddie (hax0r) activity has been run over the server or the ex-system administrator if fired recently decided to wipe out all his login tracks among with installing some other nasty rootkit or backdoor.

Under some circumstances the error might be caused also by badly written end user rotate script bugs (like shell or perl script) bugs or by a buggy deployment of Linux OS virtual machine.
The last: /var/log/wtmp: No such file or directory error is likely to happen on Ubuntu / Debian / Redhat / CentOS Linux distributions running on a Cloud PaaS service such as Amazon EC2, some of the Cloud services vendors do choose to explicitly remove /var/log/wtmp for the reason that many of end customers are using their Linux VM servers (Xen Virtualization / OpenVZ / LXC – Linux Containers) etc. irresponsibly and hence become a victim of script kiddie attacks and the failed logins attempts logged in /var/log/wtmp grow to many gigabytes.

Even some Linux distributions or system administrators of Linux server login hosts that has to keep tens of thousands of  login records monthly or are concentrating on simplicity and on an attempt to reduce size has purposefully deleted the last login entry file /var/log/wtmp file to save space.

But anyways if you happen to be missing this file always bear in mind that you might have been a victim of intrusion and you better run chkrootkit and rkhunter

Run below commands to fix the missing /var/log/wtmp

touch /var/log/wtmp
chmod 0664 /var/log/wtmp
chown root:utmp /var/log/wtmp

On some Linux distributions such as Ubuntu and Fedora you might also want to create /var/log/btmp (which is used to log failed login attempts to server)

touch /var/log/btmp
chmod 0664 /var/log/btmp
chown root:utmp /var/log/btmp

Once the files are created the last command will start logging server in logins and logouts as it is supposed to be again, e.g.:
 

linux:~# last -15
root pts/0 192.168.0.15 Fri May 5 16:41 still logged in


This article was inspired by a prior article found on root.bg the site is in Bulgarian so unfortunately you might not be able to read it, but as a content and concept it is pretty similar to pc-freak.net, actually the site author Nikolay Nikolov (known in Internet Relay Chat IRC under the pseudonym Joni-B, happened to be an old friend from youth geek IT years 🙂

Show directory structure bash script on Linux howto – See hierarchical directory tree structure one liner shell script

Friday, February 24th, 2017

show-directory-structure-see-hierarchical-directory-tree-structure-on-linux-with-tree-command-and-with-bash-shell-scripts

If you have Sys Adminned Linux or *Nix OS like, whether for some shell scripting purpose or just for sake of keeping a backup you should have definitely come
into some need to list a tree of a directories content in a hierarchical order.

The most obvious way to do that on Linux is by simply using:

1.  "tree" command (not installed by default on most Linux distributions so in order to have it on Deb / Debian based Linux do:
 

# apt-get install –yes tree


On Fedora / CentOS Redhat Linux (RHEL) etc. install with:

# yum –yes install tree

 

By the way for those that needs tree on FreeBSD / BSD UNIX, tree is also available on that platform you can install it with:
 

pkg_add -vr tree


Then simply check man tree to get idea on how to use it, the easiest way to use the command tree once package is installed is to run tree inside directory of choice, i.e.

 

$ cd /somedir
$ tree -a

To get a list of only directories with tree use:
 

$ tree -d /

If you have a colorful terminal and you like colors for readability the -C option is quite handy

 

$ tree -C /

 

tree-command-linux-hierarchical-structure-directory-tree
 

To list the directory tree with permissions included use tree cmd like so:

 

$ tree -L 2 -p /usr

/usr/
├── [drwxr-xr-x]  bin
│   ├── [-rwxr-xr-x]  [
│   ├── [lrwxrwxrwx]  2to3 -> 2to3-2.6

│   ├── [-rwxr-xr-x]  ab
│   ├── [-rwxr-xr-x]  ac

│   ├── [-rwxr-xr-x]  aclocal-1.11
│   ├── [-rwxr-xr-x]  acpi


Another truly handy option of tree is to list the directory structure index with included file sizes information

 

$ tree -L 2 -sh /bin

To list a directory tree of a search pattern, lets say all files with .conf extensions use:
 

$ tree -P *.conf

/etc/ocamlfind.conf [error opening dir]

 

 

tree -I option does exclude all petterns you don't want tree to list

Here are few other tree useful options:

  • tree -u /path/to/file – displays the users owning the files
  • tree -g /path/to/file – display the groups owning the files
  • tree -a /path/to/file – display the hidden files/folders
  • tree -d /path/to/file – display only the directories in the hierarchy


However there might be some cases where you have to support a Linux server or you just have to write a script for a non-root user and you might not have the permissins to install the tree command to make your life confortable. If that's the case then you can still use a couple of command line tools and tricks (assuming you have permissions) to list a log a directory / files and subdirectories tree structure in a hierarchical tree like command order

2. Print a list of all sub-directories and files within a directory tree

To print all directories within any path of choise on a server use
 

$ find /path/ -type d -print

 

To print all files within a root filesystem hierarchically with find command

Another way to do it in a more beautiful output is by using find in conjunction with awk
 

$ find . -type d -print 2>/dev/null|awk '!/\.$/ {for (i=1;i<NF;i++){d=length($i);if ( d < 5  && i != 1 )d=5;printf("%"d"s","|")}print "—"$NF}'  FS='/'

3. Get a list of the directories on filesystem structure with one-liner ls + sed script
 

$ ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//–/g' -e 's/^/ /' -e 's/-/|/'

 |—–debian
 |—deb-packages
 |—–IP-Country-2.28
 |——-bin
 |——-blib
 |———arch
 |———–auto

….
 

4. Print all files within root filesystem and issue any command on each of the files
 

ls -R1 / |    while read l; do case $l in *:) d=${l%:};; "") d=;; *) echo "$d/$l";; esac; done


Above command just prints all the found files with full-path if you want to check the file size or file type you just check echo command with any command you need to execute on each of the listed file

5. Get a list hierarchical directory Linux tree with bash shell scripts: Assuming that the server where you need to have a list of the directory filesystem structure in a tree fashion has bash you could use this little script called tree.sh to do the job or for a full filesystem hierarchical tree like directory structure use fulltree.sh

use-remote-dns-on-mozilla-firefox-howto-windows-linux-logo.svg

If you're using Mozilla Firefox browser to browse the Web with Traffic Tunneling via SSH Tunnel to your own Linux server like I do in order to prevent yourself traffic to be sniffed from your Work corporate computer (as most of the corporations such as IBM / Hewlett Packard / Concentrix etc. are forcing all employee PC traffic to be  to be transported via default set Windows Corporate Proxy active for all browsers.

Then you will certainly also want to prevent the DNS requests to be not logged somewhere in your Corporate IT department thus the question arises:

How to force DNS requests to be made through the Proxy server (SSH host)?

Nomatter where you're using Firefox browser with advanced proxying plugin such as FoxyProxy FF add-on or the default Proxy FF features the DNS lookups might end up in Corporate set DNS servers often forced for the computer / notebook and impossible to be changed to a custom ones as many of the Corporation internal Sharepoints and domains are only visible from their internal networks.

Thanksfully in newer versions there is an easy way to do it directly from Visual menus via:

Tools -> Options -> Advanced -> Network -> Settings

You will get a screen like below:
 

firefox-use-proxy-remote-dns-howto-screenshot

Just tick the Remote DNS and that will force Firefox to query remote Proxy server proxy DNS

 

If you happen to be running older Firefox which doesn't have the Remote DNS tick you can also try to set the setting manually:

 

  1. In firefox type this in your address bar:

    about:config

  2. Click I'll be careful I  promise.

  3. In the filter textbox, type: proxy

  4. Find the preference name called *network.proxy.socks_remote_dns*. Double click it to set it to true.

Check linux install date / How do I find out how long a Linux server OS was installed?

Wednesday, March 30th, 2016

linux-check-install-date-howto-commands-on-debian-and-fedora-tux_the_linux_penguin_by_hello

To find out the Linux install date, there is no one single solution according to the Linux distribution type and version, there are some common ways to get the Linux OS install age.
Perhaps the most popular way to get the OS installation date and time is to check out when the root filesystem ( / ) was created, this can be done with tune2fs command

 

server:~# tune2fs -l /dev/sda1 | grep 'Filesystem created:'
Filesystem created:       Thu Sep  6 21:44:22 2012

 

server:~# ls -alct /|tail -1|awk '{print $6, $7, $8}'
sep 6 2012

 

root home directory is created at install time
 

 

server:~# ls -alct /root

 

root@server:~# ls -lAhF /etc/hostname
-rw-r–r– 1 root root 8 sep  6  2012 /etc/hostname

 

For Debian / Ubuntu and other deb based distributions the /var/log/installer directory is being created during OS install, so on Debian the best way to check the Linux OS creation date is with:
 

root@server:~# ls -ld /var/log/installer
drwxr-xr-x 3 root root 4096 sep  6  2012 /var/log/installer/
root@server:~# ls -ld /lost+found
drwx—— 2 root root 16384 sep  6  2012 /lost+found/

 

On Red Hat / Fedora / CentOS, redhat based Linuces , you can use:

 

rpm -qi basesystem | grep "Install Date"

 

basesystem is the package containing basic Linux binaries many of which should not change, however in some cases if there are some security updates package might change so it is also good to check the root filesystem creation time and compare whether these two match.

chmod all directories permissions only and omit files (recursively) on Linux howto

Friday, March 11th, 2016

execute-write-read-of-user-group-and-others-on-linux-unix-bsd-explanationary-picture

If you mistakenly chmod-ed all files within directory full of multiple other subdirectories and files and you want to revert back and set a certain file permissions (read, wite execute) privileges only to all directories:
 

find /path/to/base/dir -type d -exec chmod 755 {} +


If there are too many files or directories you need to change mod use
 

chmod 755 $(find /path/to/base/dir -type d) chmod 644 $(find /path/to/base/dir -type f)

Above willl run evaluate $() all files searched and print them and pass them to chmod so if you have too many files / directories to change it will drastically reduce execution time.

An alternative and perhaps a better way to do it for those who don't remember by heart the chmod permission (numbers), use something like:
 

chmod -R u+rwX,go+rX,go-w /path

Below is arguments meaning:

    -R = recursively;
    u+rwX = Users can read, write and execute;
    go+rX = group and others can read and execute;
    go-w = group and others can't write

If like piping, a less efficient but still working way to change all directory permissions only is with:
 

find /path/to/base/dir -type d -print0 | xargs -0 chmod 755
find /path/to/base/dir -type f -print0 | xargs -0 chmod 644


For those who wish to automate and often do change permissions of only files or only directories it might be also nice to look at (chmod_dir_files-recursive.sh) shell script

Mount remote Linux SSHFS Filesystem harddisk on Windows Explorer SWISH SSHFS file mounter and a short evaluation on what is available to copy files to SSHFS from Windows PC

Monday, February 22nd, 2016

swish-mount-and-copy-files-from-windows-to-linux-via-sshfs-mount

I'm forced to use Windows on my workbook and I found it really irritating, that I can't easily share files in a DropBox, Google Drive, MS OneDrive, Amazon Storage or other cloud-storage free remote service. etc.
I don't want to use DropBox like non self-hosted Data storage because I want to keep my data private and therefore the only and best option for me was to make possible share my Linux harddisk storage
dir remotely to the Windows notebook.

I didn't wanted to setup some complex environment such as Samba Share Server (which used to be often a common option to share file from Linux server to Windows), neither wanted to bother with  installing FTP service and bother with FTP clients, or configuring some other complex stuff such as WebDav – which BTW is an accepted and heavily used solution across corporate clients to access read / write files on a remote Linux servers.
Hence, I made a quick research what else besides could be used to easily share files and data from Windows PC / notebook to a home brew or professional hosting Linux server.

It turned out, there are few of softwares that gives a similar possibility for a home lan small network Linux / Windows hybrid network users such, here is few of the many:

  • SyncThingSyncthing is an open-source file synchronization client/server application, written in Go, implementing its own, equally free Block Exchange Protocol. The source code's content-management repository is hosted on GitHub

     

     

     

     

     

    syncthing-logo

  • OwnCloud – ownCloud provides universal access to your files via the web, your computer or your mobile devices

     

     

     

     

     

    owncloud-logo

  • Seafile – Seafile is a file hosting software system. Files are stored on a central server and can be synchronized with personal computers and mobile devices via the Seafile client. Files can also be accessed via the server's web interface


seafile-client-in-browser

I've checked all of them and give a quick try of Syncthing which is really easy to start, just download the binary launch it and configure it under https://Localhost:8385 URL from a browser on the Linux server.
Syncthing seemed to be nice and easy to configure solution to be able to Sync files between Server A (Windows) and Server B(Linux) and guess many would enjoy it, if you want to give it a try you can follow this short install syncthing article.
However what I didsliked in both SyncThing and OwnCloud and Seafile and all of the other Sync file solutions was, they only supported synchronization via web and didn't seemed to have a Windows Explorer integration and did required
the server to run more services, posing another security hole in the system as such third party softwares are not easily to update and maintain.

Because of that finally after rethinking about some other ways to copy files to a locally mounted Sync directory from the Linux server, I've decided to give SSHFS a try. Mounting SSHFS between two Linux / UNIX hosts is
quite easy task with SSHFS tool

In Windows however the only way I know to transfer files to Linux via SSHFS was with WinSCP client and other SCP clients as well as the experimental:

As well as few others such as ExpandDrive, Netdrive, Dokan SSHFS (mirrored for download here)
I should say that I first decided to try copying few dozen of Gigabyte movies, text, books etc. using WinSCP direct connection, but after getting a couple of timeouts I was tired of WinSCP and decided to look for better way to copy to remote Linux SSHFS.
However the best solution I found after a bit of extensive turned to be:

SWISH – Easy SFTP for Windows

Swish is very straight forward to configure compared to all of them you download the .exe which as of time of writting is at version 0.8.0 install on the PC and right in My Computer you will get a New Device called Swish next to your local and remote drives C:/ D:/ , USBs etc.

swish-new-device-to-appear-in-my-computer-to-mount-sshfs

As you see in below screenshot two new non-standard buttons will Appear in Windows Explorer that lets you configure SWISH

windows-mount-sshfs-swish-add-sftp-connection-button-screenshot

Next and final step before you have the SSHFS remote Linux filesystem visible on Windows Xp / 7 / 8 / 10 is to fill in remote Linux hostname address (or even better fill in IP to get rid of possible DNS issues), UserName (UserID) and Direcory to mount.

swish-new-fill-in-dialog-to-make-new-linux-sshfs-mount-directory-possible-on-windows

Then you will see the SSHFS moutned:

swish-sshfs-mounted-on-windows

You will be asked to accept the SSH host-key as it used to be unknown so far

swish-mount-sshfs-partition-on-windows-from-remote-linux-accept-key

That's it now you will see straight into Windows Explorer the remote Linux SSHFS mounted:

remote-sshfs-linux-filesystem-mounted-in-windows-explorer-with-swish

Once setupped a Swish connection to copy files directly to it you can use the Send to Embedded Windows dialog, as in below screenshot

swish-send-to-files-windows-screenshot

The only 3 problem with SWISH are:

1. It doesn't support Save password, so on every Windows PC reboot when you want to connect to remote Linux SSHFS, you will have to retype remote login user pass.
Fron security stand point this is not such a bad thing, but it is a bit irritating to everytime type the password without an option to save permanently.
The good thing here is you can use Launch Key Agent
as visible in above screenshot and set in Putty Key Agent your remote host SSH key so the passwordless login will work without any authentication at
all however, this might open a security hole if your Win PC gets infected by virus, which might delete something on remote mounted SSHFS filesystem so I personally prefer to retype password on every boot.

2. it is a bit slow so if you're planning to Transfer large amounts of Data as hundreds of megabytes, expect a very slow transfer rate, even in a Local  10Mbit Network to transfer 20 – 30 GB of data, it took me about 2-3 hours or so.
SWISH is not actively supported and it doesn't have new release since 20th of June 2013, but for the general work I need it is just perfect, as I don't tent to be Synchronizing Dozens of Gigabytes all the time between my notebook PC and the Linux server.

3. If you don't use the established mounted connection for a while or your computer goes to sleep mode after recovering your connection to remote Linux HDD if opened in Windows File Explorer will probably be dead and you will have to re-enable it.

For Mac OS X users who want to mount / attach remote directory from a Linux partitions should look in fuguA Mac OS X SFTP, SCP and SSH Frontend

I'll be glad to hear from people on other good ways to achieve same results as with SWISH but have a better copy speed while using SSHFS.
