I beleive my Linux server has been hacked. All of the sudden my Samba server has disappeared, and I've noticed, from looking at the log files, that Sendmail is launching every hour! I'm trying to research this problem and I have some questions... I'm using Suse 8.1. I'm still fairly new to Linux. - Is there a better way to view the system log files other than just viewing then in an editor? - Isn't postfix installed, not sendmail? - It appears an outsider installed the Red Hat distribution of sendmail on my system. It launches every hour on the hour but fails, outputting "service smtp unknown" to the "warn" log file. Has anyone seen this and what are they trying to accomplish? - The mail log file shows postfix launching hourly starting several days before sendmail was installed, then sendmail took over! Can postfix be used to access a system? Any insight into this problem would be greatly appreciated! Thank you, Matt
