Port in use

[Francois Rabe]

How do I find what process is using what port? When I try and start Oracle I get a "port in use message". I have used netstat -an and this does not show the port or process it is complaining about I also tried netstat -u, but this gives some funny numbers in hex or so. Is there something in Tru64 Unix similar to lsof for TRU64?

Francois,

run lsof as below, and you will get enough info to fix the issue

lsof -i@hostname:port

it will give you details on the process using the port number, and you can kill it.

lsof is your tool.
It show all socket and open ports and files.
The problem is that lsof isn't in your HPUX OS.
you need download lsof.depot form this site:

/use search area and write lsof /
make sure that you install all reguared software !!!
