[HPADM] SUMMARY: Port question

Thanks to everyone who responded, too numerous to list all of you! The
consensus is that netstat, lsof and the /etc/services file will be about
all the info I can get on ports in use. No way to determine ports that
will be used if the application is not running, unless it is listed in
/etc/services as reserved. Some useful links were sent, listed below

Hi All,

Is there a way to determine all the different ports that are
used by a system, applications and all? I want to select a range of
unused ports to assign to an application but I'm not sure how to tell
which ones are unused. The /etc/services file is a list of ports and
what they are used for, but it is only as accurate as the sysadmin (me)
and I'm afraid that's not very accurate :-\ Is there another way or
ways to find this info? HP-UX 11i on rp7410.

Thanks in advance for any help ~
