This is the first time I write to the list, Big Hello To All, I administer a host on the Internet which basically doesn't really do anything. I installed some services like www,ftp,ssh,qmail / no big deal. I started playing with this machine 10 month ago. Since that I found a handful of strange thingies: - my wtmp files turn on each month, but after a short while allways gets corrupted - if I run who, it doesn't show any user - if I run last, it shows a big pile of garbage - I filter out ICMP totally, which is OK for me - but the kernel complains in every 10 minutes for some _out_ going ICMP packets, which goes to two hosts. I am absolutely sure that nor me nor any of my programs has nothing to do with that hosts - when I found this I started to look for the program which generates the ICMP packets but I didn't find anything - I checked the cron rules, but I didn't find anything - then I turned off the setuid bits from nearly every program on my host including ping and traceroute, but didn't help Do you guys suspect that my machine got exploited ? /I do, but I can't prove it./ Any ideas ?
