While looking for something else, I stumbled over these log entries that I don't understand. No other users were connected at the time, and no user has ever used these services. This box should not run the identd, imapd, or in.qpopper services! I've removed them now just to be sure. How could these entries have been created? I have never seen entries for these services in any log in /var/log.

zgrepping /var/log/* for these services found no other instances.

Could this have been a rogue web page javascript attack? Can someone help me understand what may have happened? Should I be concerned? It does look like nothing actually completed successfully.

Linux spike 2.4.25-1-686 #3 Wed Apr 14 21:56:44 EST 2004 i686 GNU/Linux
~$ cat /etc/debian_version

Thanks!
