Nagios installation and configuration in SUSE Linux

Welcome to Linux Screw! If you're new here, you may want to subscribe our RSS feed.

nagios logoAs we know Nagios is extremely popular open source network monitoring system. It watches hosts across the local area network (LAN) and/or across the Internet, services that you can specify, alerting you when things go bad. The following step-by-step guide written by Novel people (actually by Rainer Brunold) for sure would help if you plan to deploy Nagios monitoring system with Novel SUSE Linux. At least it helped me :)

I don't want to write here a full documentation about Nagios, I prefer to give you a basic installation guide so you can set it up very easy and play with it yourself. The installation guide will show you how to install Nagios as well as some interesting extensions and how they integrate into each other. During this installation you will make many modifications to the installation that will help to understand how it works, how you can integrate systems and different services. I will also provide some articles about monitoring special services where I describe what they do and what configuration changes are needed. All together should give you a very good overview and documentation on how you can enhance the Nagios installation yourself.

The rest of the article is here. Respect to the author!

Run Photoshop with Ubuntu (or any other Linux)

photoshop logoAdobe Photoshop (or simply Photoshop), is a graphics editor developed and published by Adobe Systems. Currently it’s market leader for commercial bitmap and image manipulation, and is the flagship product of Adobe Systems. Unfortunately it’s available for M$ Windows and Apple OS X users only. Thanks to heaven (and Wine’s developers of course) there is Wine allowing to execute M$ Windows applications (from simple executables to M$ Office and Adobe Photoshop) in Linux. The following instructions will help you to run Photoshop with you favorite Linux like Ubuntu Feisty / Gutsy, Fedora, Debian or OpenSUSE (actually it’s no matter what distribution you use).

1. Install wine (in Ubuntu just execute sudo aptitude install wine, Fedora users may run sudo yum install wine).

2. Configure "Wine Is Not an Emulator":

$ winecfg

When ~/.wine directory is created configuration tool will start and you can set up a virtual desktop with the graphics tabs.

3. Install Photoshop cs2

First of all mount your Photoshop installation CD with the option -o unhide. This will prevent problems with hidden files during the installation.

$ sudo mount -t iso9660 -o unhide /dev/cdrom /media/cdrom0

Then proceed with installation (rather trivial procedure)

$ cd /media/cdrom0
$ wine setup

photoshop cs2 wineAfter this Photoshop setup should start without any errors. Just complete it like you're in M$ Windows (predatory OS definitely). In case the installation is finished and wasn't crashed you can start desired image editor.

4. Run Photoshop

$ cd /home/tom/.wine/drive_c/Program\ Files/Adobe/Adobe\ Photoshop\ CS2
~/.wine/drive_c/Program Files/Adobe/Adobe Photoshop CS2$ wine photoshop.exe

This would show several errors like these ones:

err:shell:HCR_GetFolderAttributes HCR_GetFolderAttributes should be called for simple PIDL’s only!
err:shell:HCR_GetFolderAttributes HCR_GetFolderAttributes should be called for simple PIDL’s only!

There is alternative solution - USE GIMP! As for me, I prefer alternative solution. ;)

Convert WMV into AVI with Ubuntu

mplayer logoActually this tip is applicable to any Linux distribution mencoder can be run at (like Ubuntu, Debian, Fedora, Suse and even Slackware :) )

MEncoder is a free command line video decoding, encoding and filtering tool released under the GNU General Public License. It is a close sibling to MPlayer and can convert all the formats that MPlayer understands into a variety of compressed and uncompressed formats using different codecs

Here is the fastest way to perform wmv to avi conversion:

  1. Ubuntu:
  2. sudo apt-get install mencoder
    mencoder infile.wmv -ofps 23.976 -ovc lavc -oac copy -o outfile.avi

  3. Fedora:
  4. sudo yum install mencoder
    mencoder infile.wmv -ofps 23.976 -ovc lavc -oac copy -o outfile.avi

Get changelog information from RPM and DEB package

Here is a nice Linux tip: to get change information of some RPM package it’s enough to execute the following command rpm -q --changelog package for example rpm -q --changelog openssh will output something like:


* Fri Mar 03 2006 Tomas Mraz - 4.3p2-4
- allow access if audit is not compiled in kernel (#183243)

* Sat Feb 25 2006 Tomas Mraz - 4.3p2-3
- enable the subprocess in chroot to send messages to system log
- sshd should prevent login if audit call fails

* Wed Feb 22 2006 Tomas Mraz - 4.3p2-2
- print error from scp if not remote (patch by Bjorn Augustsson #178923)

* Sat Oct 30 1999 Damien Miller
- Back to old binary names

* Fri Oct 29 1999 Damien Miller
- Use autoconf
- New binary names

* Thu Oct 28 1999 Damien Miller
- Initial RPMification, based on Jan "Yenya" Kasprzak’s spec.

To look through whole output it would be useful to use more or less commands:
rpm -q --changelog /path/to/package.rpm | less

Similar command is available also in Debian: dpkg-parsechangelog. It reads and parses the changelog of an unpacked Debian source tree and outputs the information in it to standard output in a machine-readable form.

Web server cluster with SUSE Linux Enterprise Server 10

Spreading a workload across multiple processors, coupled with various software recovery techniques, provides a highly available environment and enhances overall RAS (Reliability, Availability, and Serviceability) of the environment. Benefits include faster recovery from unplanned outages, as well as minimal effects of planned outages on the end user.To get the most out of this article, you should be familiar with Linux and basic networking, and you should have Apache servers already configured. Our examples are based on standard SUSE Linux Enterprise Server 10 (SLES10) installations, but savvy users of other distributions should be able to adapt the methods shown here.
