I decided this morning to install antivirus on my desktop running Fedora 13.
I had to do some looking around before I finally got it installed.
First
yum install clamav-scanner
yum install clamav-update
Second
cp /usr/share/doc/clamav-server-0.96.1/clamd.conf /etc/clamd.conf
Third
vim /etc/clamd.conf /etc/freshclam.conf
Follow the instructions in the file where it says:
# Comment or remove the line below.
Example
If you see errors like below refer to above.
ERROR: Please edit the example config file /etc/freshclam.conf.
ERROR: Please edit the example config file /etc/clamd.conf.
ERROR: Can't parse the config file /etc/clamd.conf
This is my personal blog to keep track of all those sysadmin items that keep recurring in my life that I can never remember.

Adding a Superuser Account to Linux
I have been testing a Linux Application and found it useful to create a second superuser account on the box besides the root account. Below are the list of commands that I used:
Check the current root account's user ID, group ID and group memberships:
id root
Create account with superuser privileges (this is for CentOS 5.5):
adduser -u 0 -o -g 0 -G 0,1,2,3,4,6,10 LOGIN
passwd LOGIN
Verify change:
id LOGIN
less /etc/passwd
less /etc/shadow
less /etc/group
To change the account properties:
usermod [options] LOGIN
To delete the account if you don't care about the home directory:
userdel -r LOGIN
If you chose not to delete the home directory and need to go back and do it later:
rm -rf /home/LOGIN
A better way of doing this that aligns with best practice is to create a user and assign it to the wheel group and use 'sudo' instead:
adduser -G 10 LOGIN
Use 'visudo' to uncomment the below line:# %wheel ALL=(ALL) ALL
Check the current root account's user ID, group ID and group memberships:
id root
Create account with superuser privileges (this is for CentOS 5.5):
adduser -u 0 -o -g 0 -G 0,1,2,3,4,6,10 LOGIN
passwd LOGIN
Verify change:
id LOGIN
less /etc/passwd
less /etc/shadow
less /etc/group
To change the account properties:
usermod [options] LOGIN
To delete the account if you don't care about the home directory:
userdel -r LOGIN
If you chose not to delete the home directory and need to go back and do it later:
rm -rf /home/LOGIN
