The UDP:799 port is open on my rhel 3 server.
I can't find which service is behind it. I've tried everything with no success. Now I suspect to be a backdoor or something like this
1. #nmap -sU localhost
2. netsta -tupan | grep 799
udp 0 0 0.0.0.0:799 0.0.0.0:* -
3.lsof -i :799 -> nothing
4. lsof -V -i UDP -> nothing related
Do you have any idea? I thing this is very difficult of impossible finding what is behind this port.
What could I do next? Please give me some hints!!
Thanks in advance!
