sudo in Fedora 8
Most of u who have worked in ubuntu must be familiar with th sudo command which i really liked a lot 
when i switched to fedora 8 i had to login as root using su each and every time to execute small commands.. so i set out to search for a solution for sudo .. Fedora has sudo by default but u need to cinfigure it a bit to make it work like sudo in ubuntu..
when u do a sudo in fedora and give ur accnt passwd it wud give a message saying ” users is not in sudoers list “
So wht we do is add our user account to sudoers list which maps the privelges tht a user get by executing sudo command.
open sudoers which is in /etc/sudoers using the command visudo.. if it says command not found, then execute it from /usr/sbin/visudo ( u can add this permanantly to ur path varible using the previous post in my blog )
in the last line add the following line
user ALL=(ALL) ALL
where user is ur user name.. suppose my user name is sathya i wud do
sathya ALL=(ALL) ALL
sudo has an expiry time of 5 minutes by default to change tht add timestamp_timeout=0 to timestamp_timeout=0 to Defaults env_reset line….
now press esc and :wq and now sudo is ready for u !!!
[...] yum -y install cpio rpm ( for configuring sudo on fedora refer here or use su -c or login as root [...]
I cannot run visudo because I AM NOT ON THE SUDOERS LIST!
to give ur self the sudo permission u obviously need a root access.. open visudo as root and u can grant sudo privileges to any user u want … if visudo doesnt require root access , doesnt it mean tht any body can get root access
visudo required root access, and when I type in sudo visudo it said the same thing it always did about me not being on the sudoers list.

Thanks to that page I found out I can type “su” to drop to a root terminal.
su is like sudo -i except it uses the root password and anyone who knows the root password can uses it instead of using the password of a logged on user on the sudoers list.
