The lsof output shows a program named iptrans is listening on 4965. Try to find
the program using 'locate iptrans' on the machine that has it. Then use 'rpm -q
--whatprovides pathname' to see what rpm package it was installed from. If it
was installed from a yum repository and you have matching repositories set up,
you should be able to duplicate it on the other machine with 'yum install
packagename' (and perhaps some configuration afterwards). I don't recognize
this program, though. Are you sure it came from an rpm package?
