This question is similar to Network port open, but no process attached?
I've tried everything from there, reviewed the logs, etc... and can't find anything.
My netstat shows a TCP listening port and a UDP port without a pid. When I search lsof for those ports nothing comes up.
netstat -lntup Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:44231 0.0.0.0:* LISTEN - udp 0 0 0.0.0.0:55234 0.0.0.0:* -
The following commands display nothing:
lsof | grep 44231 lsof | greo 55234 fuser -n tcp 44231 fuser -n udp 55234
After rebooting, those "same" two connections are there except with new port numbers:
netstat -lntup Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:45082 0.0.0.0:* LISTEN - udp 0 0 0.0.0.0:37398 0.0.0.0:* -
And once again, the lsof and fuser commands show nothing.
Any ideas what they are? Should I be concerned about them?
