How to install Google Chrome web browser on Debian 7 Wheezy Linux

Wednesday, September 4th, 2013

How to install Google Chrome web browser on Debian Gnu Linux Chrome and tux logo
Just installed Debian 7 Linux and wondered how to install Google Chrome Browser on Debian Wheezy. It took me a while until I figure it out, as direct download from Google after searching for Chrome Linux had library requirements which are missing from Debian 7 Wheezy repositories.
Here is how;

1. Add  Wheezy Backports and Google's Chrome Repository to /etc/apt/sources.list

echo 'deb http://ftp.debian.org/debian/ wheezy-backports main contrib non-free' >> /etc/apt/sources.list
echo 'deb http://dl.google.com/linux/chrome/deb/ stable main' >> /etc/apt/sources.list

2. Install Google Chrome with apt-get

Here you have few options install Google Chrome Beta (whether you prefer you're an innovator), install unstable – if you prefer latest functionality and don't count on stability or install stable version.

a) Install Google Chrome Beta

apt-get install --yes google-chrome-beta

b) Install Google Chrome Unstable

apt-get install --yes google-chrome-unstable

c) Install Google Stable

apt-get install --yes google-chrome-stable

I personally prefer always to keep stable so prefer to install google-chrome-stable.

Only reason I need Google-Chrome is for testing how websites looks with it. Otherwise I don't recommend this browser to anyone who cares for his security. Obviously as Chrome is product of Google it is almost certainly it keeps complete surveillance on what you do on the net.

That's all happy web development with Chrome on Debian 🙂
 

Debian Linux: Installing and monitoring servers with Icanga (Nagios fork soft)

Monday, June 3rd, 2013

icinga-monitoring-processes-and-servers-linux-logo

There is plenty of software for monitoring how server performs and whether servers are correctly up and running. There is probably no Debian Linux admin who didn't already worked or at least tried Nagios and Mointor to monitor and notify whether server is unreachable or how server services operate. Nagios and Munin are play well together to prevent possible upcoming problems with Web / Db / E-mail services or get notify whether they are completely inaccessible. One similar "next-generation" and less known software is Icanga.
The reason, why to use Icinga  instead of Nagios is  more features a list of what does Icinga supports more than Nagios is on its site here
I recently heard of it and decided to try it myself. To try Icanga I followed Icanga's install tutorial on Wiki.Icanga.Org here
In Debian Wheezy, Icinga is already part of official repositories so installing it like in Squeeze and Lenny does not require use of external Debian BackPorts repositories.

1. Install Icinga pre-requirement packages

debian:# apt-get --yes install php5 php5-cli php-pear php5-xmlrpc php5-xsl php5-gd php5-ldap php5-mysql

2. Install Icanga-web package

debian:~# apt-get --yes install icinga-web

Here you will be prompted a number of times to answer few dialog questions important for security, as well as fill in MySQL server root user / password as well as SQL password that will icinga_web mySQL user use.

3. Enable Apache mod_rewrite
 

 

debian:~# a2enmod rewrite
debian:~# /etc/init.d/apache2 restart


4. Icinga documentation files

Some key hints on Enabling some more nice Icinga features are mentioned in Icinga README files, check out, all docs files included with Icinga separate packs are into:
 

debian:~# ls -ld *icinga*/
drwxr-xr-x 3 root root 4096 Jun  3 10:48 icinga-common/
drwxr-xr-x 3 root root 4096 Jun  3 10:48 icinga-core/
drwxr-xr-x 3 root root 4096 Jun  3 10:48 icinga-idoutils/
drwxr-xr-x 2 root root 4096 Jun  3 10:48 icinga-web/

debian:~# less /usr/share/doc/icinga-web/README.Debian debian:~# less /usr/share/doc/icinga-idoutils/README.Debian

5. Configuring Icinga

Icinga configurations are separated in two directories:

debian:~# ls -ld *icinga*

drwxr-xr-x 4 root root 4096 Jun  3 10:50 icinga
drwxr-xr-x 3 root root 4096 Jun  3 11:07 icinga-web

>

etc/icinga/ – (contains configurations files for on exact icinga backend server behavior)

 

/etc/icinga-web – (contains all kind of Icinga Apache configurations)
Main configuration worthy to look in after install is /etc/icinga/icinga.cfg.

6. Accessing newly installed Icinga via web

To access just installed Icinga, open in browser URL – htp://localhost/icinga-web

icinga web login screen in browser debian gnu linux

logged in inside Icinga / Icinga web view and control frontend

 

7. Monitoring host services with Icinga (NRPE)

As fork of Nagios. Icinga has similar modular architecture and uses number of external plugins to Monitor external host services list of existing plugins is on Icinga's wiki here.
Just like Nagios Icinga supports NRPE protocol (Nagios Remote Plugin Executor). To setup NRPE, nrpe plugin from nagios is used (nagios-nrpe-server). 

To install NRPE on any of the nodes to be tracked;
debian: ~# apt-get install –yes nagios-nrpe-server

 Then to configure NRPE edit /etc/nagios/nrpe_local.cfg


 

Once NRPE is supported in Icinga, you can install on Windows or Linux hosts NRPE clients like in Nagios to report on server processes state and easily monitor if server disk space / load or service is in critical state.

How to install / update Wine windows emulator 1.4 on Debian Squeeze Linux

Monday, April 29th, 2013

wine linux ms windows emulator logo with microsoft windows
Debian Squeeze
Linux depending on RC release comes with a Version of WINE Windows emulator 0.9.8 or wine 1.0.1-3.1. This wine version is very out of date already and many of the new win software working well with newer wine releases doesn't work. We all know the down-side of Debian stable releases you always stay a bit outdated.

Thanksfully there is an easy way to upgrade to newer wine version and hence have more Windows software properly running on Squeeze. To do so you need to add custom following wine custom deb repository:

deb http://main.mepis-deb.org/mepiscr/repo/ mepis85cr main

i.e.

debian:~# echo 'deb http://main.mepis-deb.org/mepiscr/repo/ mepis85cr main' >> /etc/apt/sources.list

Then update wine with apt-get:

debian:~# apt-get update
....
debian:~# apt-get --yes install wine ....
The following NEW packages will be installed:
fonts-droid ttf-droid ttf-umefont ttf-unfonts-core wine-gecko
The following packages will be upgraded: wine
1 upgraded, 5 newly installed, 10 to remove and 86 not upgraded.
Need to get 135 MB of archives.

debian:~# dpkg -l |grep -i wine

rc libwine 1.0.1-3.1 Windows API implementation – library
ii playonlinux 3.7.6-1 front-end for Wine
ii wine 1.4-1mcr8.5+1 Windows Compatibility Layer (Binary Emulator and Library)
rc wine-bin 1.0.1-3.1 Windows API implementation – binary loader
ii wine-gecko 1.4.0-1mcr85+2 Microsoft Windows
Compatibility Layer (Web Browser)

That's all enjoy 🙂

Install latest WINE – Win Emulator unstable version on Debian stable Linux

Saturday, April 27th, 2013

wine emulator logo install wine on Debian GNU / Linux

Installing latest stable version of wine is only possible and safe via deb repository on 32 bit Debian archtecture.

Whether not sure about your Debian architecture run:

linux:~# dpkg --add-architecture i386 To install latest unstable version of wine which though unstable is often much useful to its stable predecessors add wine-unstable repository linux:~# wget -q -O- http://www.tataranovich.com/tataranovich.asc | apt-key add -

Finally install / update (whether installed) with:
 

linux:~# apt-get update
linux:~# apt-get --yes install wine-unstable:i386

Enjoy ! 🙂

How to set repository to install binary packages on amd64 FreeBSD 9.1

Friday, January 11th, 2013

Though, it is always good idea to build from source for better performance of Apache + MySQL + PHP, its not worthy the time on installing minor things like; trafshow, tcpdump or deco (MC – midnight commander like native freebsd BSD program).

If you're on a 64 bit version of FreeBSD ( amd64) 9.1 and you try to install a binary package with;

freebsd# pkg_add -vr vim

Ending up with an error;

Error: Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9.1-release/Latest/vim.tbz: File unavailable (e.g., file not found, no access)
pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9.1-release/Latest/vim.tbz' by URL
pkg_add: 1 package addition(s) failed

The error is caused by lack of special packages-9.1-release directory existing on FreeBSD.org servers. I've realized this after doing a quick manual check opening ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64. The existing URL containing working fbsd 9.1 binaries is:

ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/
h

You will have to set a repository for FreeBSD 9.1 amd64 packages manually with cmd:
freebsd# echo $SHELL
/bin/csh
freebsd# setenv PACKAGESITE ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/

If you're on bash shell use export instead:

freebsd# export PACKAGESITE="ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/"

To make ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/ as a permanent binary repository:

echo 'setenv PACKAGESITE ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/' >> /root/.cshrc

or

echo 'export PACKAGESITE="ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-9-current/Latest/"' >> /root/.bashrc

Now, pkg_add as much as you like 😉

Finding nearest package software repository in Debian GNU / Linux

finding debian Ubuntu package repository icon

I’m about to chage the good old computeres until this very moment this blog and few other website were running on. Right now, I’m installing the brand new machine Lenovo ThinkCentre Edge great and hopefully powerful enough machine to take care for the periodic occuring high traffic loads which break up webserver or SQL server. Well anyways, I just installed latest Debian GNU / Linux on this brand new piece of iron. During install I couldn’t connect the PC to network so Debian install was unable to determine, the nearest Debian package repository, hence after completing install and anually configuring Debian network . Because during install the system had no connection with the Internet, no proper package repository definitions were present in /etc/apt/sources.list, hence I had to find the nearest package software repository. Normally one can check in Debian official WorldWide Mirror sites full address list and determine by some rationalization with ping or / and a manual package download which repo is quickest. There is thanksfully a better automated way one can determine the closest deb Debian / Ubuntu located repository with netselect-apt.

Here is apt-cache description:

debian:~# apt-cache search netselect-apt
netselect-apt - speed tester for choosing a fast Debian mirror

Using the tool is trivial, just install, run it and it does all 4 u 🙂

1. Install netselect-apt

debian:~# apt-get install --yes netselect-apt

2. Run it

debian:~# netselect-apt
....
130/debian/); keeping only under first name.
netselect: 2 (2 active) nameserver request(s)...

Duplicate address 200.236.31.3 (http://debian.c3sl.ufpr.br/debian/, http://ftp.br.debian.org/debian/); keeping only under first name.
netselect: 1 (1 active) nameserver request(s)...
Running netselect to choose 1 out of 383 addresses.
.............................................
The fastest server seems to be:
http://debian.telecoms.bg/debian/

Writing sources.list.
sources.list exists, moving to sources.list.1346964774
Done.

As you can see from output, the tool finds the quickest download deb repository and generate /etc/apt/sources.list file in current directory, where it is run in, in this exact case it creates it in root user home dir – e.g. in /root/ directory. Once the repo address is found you can copy paste it with some text editor to /etc/apt/sources.list or move it over /etc/apt/sources.list;

debian:~# cp -rpf /etc/apt/sources.list /etc/apt/sources.list.$(date +%d_%m_%Y|sed -e 's/^ *//')
debian:~# mv /root/sources.list /etc/apt/sources.list

Just in case as I always make first copy of original sources.list, this is not necessery but IMHO a generally good sysadmin habit 🙂

Besides netselect-apt, which automatically choose between all available list of software repo servers, there is also netselect tool. netselect does basically the same the only difference is one has to manually pass by as arguments deb package repositories and the tool then does tests and returns which is the overall quickest deb download source.

netselect is definitely useful if you have started few own mirror of repositories and want to determine which is the best among them.

Here is how netselect is used:

# netselect -vv ftp.fceia.unr.edu.ar ftp.kulnet.kuleuven.ac.be \
ftp.cdrom.com ftp.debian.org ftp.de.debian.org
ftp.fceia.unr.edu.ar 2792 ms 23 hops 100% ok ( 1/ 1) [ 9213]
ftp.kulnet.kuleuven.ac.be 9999 ms 30 hops 0% ok
ftp.cdrom.com 94 ms 8 hops 100% ok (10/10) [ 169]
ftp.debian.org 46 ms 15 hops 100% ok (10/10) [ 115]
ftp.de.debian.org 9999 ms 30 hops 0% ok

According to above output, the “best reachable” (quickest) repository is the one to which are the least miliseconds – ftp.debian.org

Installing XMMS on Debian Squeeze from a Package / Installing XMMS on Debian – the debian way

Tuesday, July 17th, 2012

installing xmms on debian squeeze linux playing free software song green skin screenshot

I use Debian Linux for my desktop for quite some time; Even though there are plenty of MP3 / CD players around in Debian, I’m used to the good old XMMS, hence I often prefer to use XMMS to play my music instead of newer players like RhythmBox or audacious.
Actually audacious is not bad substitute for XMMS and is by default part of Debian but to me it seems more buggy and tends to crash during playing some music formats more than xmms ….

As most people might know, XMMS is no longer supported in almost all modern Linux distributions, so anyone using Debian, Ubuntu or other deb derivative Linux would have to normally compile it from source.
Compiling from source is time consuming and I think often it doesn’t pay back the effort. Thanksfully, though not officially supported by Debian crew XMMS still can be installed using a deb xmms prebuilt package repository kindly provided by a hacker fellow knuta.

Using the pre-build deb packages, installing xmms on new Debian installs comes to:

debian:~# echo 'deb http://www.pvv.ntnu.no/~knuta/xmms/squeeze ./' >> /etc/apt/sources.list
debian:~# echo 'deb-src http://www.pvv.ntnu.no/~knuta/xmms/squeeze ./' >> /etc/apt/sources.list
debian:~# apt-get update && apt-get -y install xmms

There are also deb xmms built for Ubuntu, so Ubuntu users could install xmms using repositories:

deb http://www.pvv.ntnu.no/~knuta/xmms/karmic ./
deb-src http://www.pvv.ntnu.no/~knuta/xmms/karmic ./
That’s all now xmms is ready to use. Enjoy 🙂

Am I missing some important program?

How to add repository manually from command line in Ubuntu Linux

Sunday, January 8th, 2012

I'm on a way trying to install Free Mega Games Pack and I'm facing troubles in following the instructions to add a the latest development wine version described on http://www.winehq.org/download/ubuntu
The guys from WineHQ has to update the wine install instructions, since the instructions are targetting older versions of Ubuntu which are not compatible with newer Ubuntus which comes natively with Unity
In order to complete the step in adding the WineHQ Ubuntu PPA development repository my only way was to add it using command line.
Here is how:

root@ubuntu:~# apt-add-repository ppa:ubuntu-wine/ppa
You are about to add the following PPA to your system:
Latest official WineHQ releases
Welcome to the Wine Team PPA. Here you can get the latest available Wine betas for every supported version of Ubuntu. This PPA is managed by Scott Ritchie, and is a replacement for the WineHQ budgetdedicated.com repository used for Jaunty and earlier.
More info: https://launchpad.net/~ubuntu-wine/+archive/ppa
Press [ENTER] to continue or ctrl-c to cancel adding it
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.bvo21sFWKG --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80/ --recv 883E8688397576B6C509DF495A9A06AEF9CB8DB0
gpg: requesting key F9CB8DB0 from hkp server keyserver.ubuntu.com
gpg: key F9CB8DB0: public key "Launchpad PPA for Ubuntu Wine Team" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)

Similarly adding a PPA repository on Debian is also possible by using a little shell script add-apt-repository.sh . add-apt-repository.sh simulates what ubuntu's apt-add-repositry python script does.

It is educative to mention PPA stands for (Personal package Archive) and the difference between normal repository and PPA is mainly in the fact that PPA repositories makes a package distributed by the repository like the native Ubuntu packages issued by Canonical.
Once for example a new version of a file is placed in PPA deb package repository, the newer package will be automatically installed to the system using it.
