Install Yum on RHEL4
In my company they purchased some software from Autodesk that comes on Redhat Enterprise 4, i needed to install some packages on the system for the use of some internal applications, instead of installing packages and all the dependencies, i though using automatic installer like yum would be better, below is the steps to have yum installed on your RHEL4 machine :
1. Install rhel4
2. Download Yum rpm package
wget http://gd.tuwien.ac.at/opsys/linux/yum/2.0/yum-2.0.5-1.noarch.rpm
3. Install the package
rpm -Uvh yum-2.0.5-1.noarch.rpm4. Edit repositories location
nano /etc/yum.conf
Change the baseurl in [base] to
http://mirror.centos.org/centos/4/os/$basearch/
Change the baseurl in [updates] to
http://mirror.centos.org/centos/4/updates/$basearch/
5- Install the full yum with all its dependencies.
yum install yum
Ubuntu 8.10 Intrepid – Fix Static IP & Network Manager Problem
Hey all,
today i have installed the new release of Ubuntu, 8.10 Intrepid
but i had a problem setting my IP to a static one, when i do this through the network manager, and when i edited the network files manually nothing worked, so here is the steps i followed to solve the problem :
first i removed the network manager
sudo update-rc.d -f NetworkManager remove
then i added my network configuration by editing the file /etc/network/interfaces
sudo gedit /etc/network/interfaces
so it looks like
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.xxx netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.xxx
then i edited the file /etc/resolv.conf to add my DNS
sudo nano -w /etc/resolv.conf
to look like
# Generated by NetworkManager nameserver 192.168.1.xxx
then i restart the networking by :
sudo /etc/init.d/networking restart
if u still have problems, i suggest you restart the machine and check, the above steps is how i got my network up .
enjoy the new Ubuntu 
Install Subversion with Web Access on Ubuntu 8.04 (Hardy Heron)
well, it is very useful to have a subversion server so u can have different versions of your applications; for back up and to be able to restore old versions, and be able to share the project with the team, when there is more than one developer working on it.
1- install apache
sudo apt-get install apache2
2- install subversion
sudo apt-get install subversion libapache2-svn
3- We're going to create the subversion repository in /svn
sudo svnadmin create /svn
4- Now we'll need to edit the configuration file for the subversion webdav module
sudo gedit /etc/apache2/mods-enabled/dav_svn.conf
we will comment the following line, so we can access the repository using the address http://www.servername.com/svn
<Location /svn>
</Location>
and the following line to enable the dav module
DAV svn
and the following line to set the path to our repository which is /svn in our case
SVNPath /svn
and the following 3 lines to enable basic authentication
AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd
5- We create a user to have access to our repository
sudo htpasswd -cm /etc/apache2/dav_svn.passwd
where is the desired login name
6- We restart the apache server
sudo /etc/init.d/apache2 restart
7- You can access now the repository using the address : http://www.servername.com/svn

Know your System Administrator
There are four major species of Unix sysad:
1.The TECHNICAL THUG. Usually a systems programmer who has been forced into system administration; writes scripts in a polyglot of the Bourne shell, sed, C, awk, perl, and APL.
2.The ADMINISTRATIVE FASCIST. Usually a retentive drone (or rarely, a harridan ex-secretary) who has been forced into system administration.
3.The MANIAC. Usually an aging cracker who discovered that neither the Mossad nor Cuba are willing to pay a living wage for computer espionage. Fell into system administration; occasionally approaches major competitors with indesp schemes.
4.The IDIOT. Usually a cretin, morpohodite, or old COBOL programmer selected to be the system administrator by a committee of cretins, morphodites, and old COBOL programmers.
