How to know which process is bound to a port

[Enrico Venturi]

Hi colleagues,
I'm using a 3PP software which binds to a DLPI to use a LAN card; the bind fails because the device is busy.
How can I get the Id of the process already bound to that DLPI?

thanks
Enrico

lsof -i TCP:xxxx

Hi Ludovic,
what should I put in place of xxxx?
sorry for my stupid question maybe ;-)

lsof is indeed the way to go.
Shame it's not installed by default.

For recent OS versions get it here:
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.78/

For the older versions, you can try on my site:
http://mirrors.develooper.com/hpux/downloads.html

Be SURE to pick the correct version, otherwise it will either not run at all, or give the wrong results. When all fails, build from source.

Enjoy, Have FUN! H.Merijn

Hi Enrico,

in this form:

[46][protocol][@hostname|hostaddr][:service|port]

see lsof man page
