[NMLUG] SSH bot going around

[westbrook at swestbrook.org (Steven Westbrook)]

Hi all.. I was just going through some of my logs and recognized there 
seems to be a bot or a group of people trying to hack into linux boxes via 
ssh.  Just a warning... I'd reccomend only allowing in a select few people 
-- and disabling root access through ssh.  It can be done by going into 
/etc/ssh/sshd_config and adding a line called AllowUsers and then listing 
the names for those with few accounts needing access.  There's also a way 
through pam.d to add a long list of names that if asked I'll look back up.
