It does sound like the source of the request is on your local machine.
Add a firewall rule to log all input chain activity on all interfaces
for tcp port 113. You might also check if you identd is actually running
right. Assuming RH, run:
/etc/rc.d/init.d/identd status

Also try to telnet to port 113 on localhost, type in some nonsense, see
if it accepts and drops you after typing in nonsense (it should).
