Other resources

I subscribe to the CentOS (CentOS is a free clone of Red Hat Enterprise Linux) mailing list as a way to keep up with what's going on with CentOS and because I learn something just from reading about the problems that others have run into and gone to "the list" to get help or solutions. The following thread showed up in today's mail concerning how to prevent brute force attacks against a server that allows secure shell (ssh) logins:

http://article.gmane.org/gmane.linux.centos.general/81276

There are a few other threads that are current (e.g., "How can I tell if I've been hacked") as well as other discussions.

Besides just this particular mailing list, Gmane provides archives for pretty much any significant mailing list on the Internet. I'm sure there are other lists that would be usefull if you have the time to keep up with the list traffic. As with the thread I specified above, an appropriate mailing list is a great way to get help with a particular problem. The only down side is that lists that will get you a quick response generally have enough traffic to swamp you while low volume lists mean you might not get a response ever or at least in the time frame that you need.

Cheers,
