[cobalt-users] Securing a server

[Cody Watkins <codyw@xxxxxxxxxxxxxxxxx>]

Hey all,

I want to secure my server to prevent hackers from getting easily. I 
already had one get in and had to redo the machine. So far I have installed 
SSH and set it so SSH and telnetd can only be accessed from my IP address 
of my home machine. What else should I do?

-Upgrade sendmail?
-What about rsh, rlogin?
-Upgrade Bind?

Any advice will be appreciated.

Thanks,
Cody Watkins
