Who & what process has port open ?

Hello HP,

How do I figure out "who" or "what process"
has a port open?

Info from "netstat -a" :

Proto Recv-Q Send-Q Local Address Foreign Address (state)
tcp 0 0 hohp120.6011 hohp120.58438 ESTABLISHED

you can install and use lsof program which will tell you what program uses what port.

Regards,

Fred

try using lsof.
#lsof -ufoo
option pro-duces a listing of all network files OR files belonging to processes owned by user ``foo''.

Hi Jerry,

Search the forums for 'lsof' to find the depot for 11i. Once it is downloaded, run 'lsof -i tcp:6011'. It will show the process listening at 6011 with it's owner.
