Hopefully, I'm right on this list. if not, please forward. Running CURRENT as of FreeBSD 11.0-CURRENT #3 r287780: Mon Sep 14 13:34:16 CEST 2015 amd64, I check via nmap for open sockets since I had trouble protecting a server with IPFW and NAT.
I see a service (nmap) Host is up (0.041s latency). Not shown: 998 filtered ports PORT STATE SERVICE 843/tcp open unknown and via sockstat -l -p 843, I get this: ? ? ? ? tcp4 *:843 *:* I double checked all services on the server and i can not figure out what daemon or service is using this port. The port is exposed throught NAT (I use in-kernel NAT on that system). This service is accessible via telnet host-ip 843: Trying 85.179.165.184... Connected to xxx.xxx.xxx.xxx. Escape character is '^]'. Well, I feel pants-down right now since it seems very hard to find out what service is keeping this socket open for communications to the outside world. Anyone any suggestions?
