Linux Few Tips n Tricks ! Unmanaged Post, Will edit later . . .

Fedora 10 update GDM config to allow root login on GUI Mode
===========================================================

Open /etc/pam.d/gdm using gedit or vi text editor, enter:
gedit /etc/pam.d/gdm

Find line that read as follows:

auth required pam_succeed_if.so user != root quiet

Remove or comment out line by prefixing #.

# auth required pam_succeed_if.so user != root quiet

==============================================
CONFIGURING LAN IP ADDRESS:

You can determine your IP by running:

/sbin/ifconfig -a

Look at the entry for eth0

To change your IP edit the file /etc/systconfig/network-scripts/ifcfg-eth0

then run

service network restart

==============================================
CONFIGURING WEBMIN via YUM:

Using the Webmin YUM repository

If you like to install and update Webmin via RPM, create the /etc/yum.repos.d/webmin.repo file containing :

[Webmin]
name=Webmin Distribution Neutral
#baseurl=http://download.webmin.com/download/yum
mirrorlist=http://download.webmin.com/download/yum/mirrorlist
enabled=1

You should also fetch and install my GPG key with which the packages are signed, with the command :

rpm –import http://www.webmin.com/jcameron-key.asc

You will now be able to install with the command :

yum install webmin

All dependencies should be resolved automatically
