Got 2 questions both deal with /var/log/messages
A) I have entries every hour from root, saying a crond is openeing a sessions for root by root, and then at the exact same time, crond is closing the session
Oct 23 17:01:01 localhost crond(pam_unix): session opened for user root by
Oct 23 17:01:01 localhost crond(pam_unix): session closed for user root
Why is this happening?? There are no crontab jobs for root.
B) I also have entries from annonymous users, obviously trying to hack any machine they can. Is there a way to sto this from happening (Aside from blocking all IPs)??
Thanks so much!!!
