Finding Process Info Associated to a Given Port in HP-UX

Question

I need to find information for a process that's using a given port number, such as 8080. More specifically, I'm interested in finding out the full path of the program.

How can I do that in HP-UX?

Solution

Follow these steps:

1. Find the PID (process ID) of the process using the port (e.g. 8080):

   lsof -i tcp:8080
   

   This will return: something like this:

   java       1829      154  101u  IPv4  0xd6cc04c0       0t0      TCP *:8080 (LISTEN)
   

   The second column contains the PID we're after.

2. Find info about the process with a given PID (e.g 1829):

   ps -f -p 1829
   

   This will show, among other things, the path to the program of the process we're after:

   usr1  1829 20693  0 11:13:13 ?         1:37 /d03/app/jvm/hp142/jre/bin/PA_RISC2.0/java -ms512M

You can get LSOF for hpux from here: h20392.www2.hp.com/portal/swdepot/… or hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.89

Doesn't work on HPUX: # netstat -nlp netstat: illegal option -- l

[Kaiden Prince]

Try netstat -np note the missing l

[Admin]

still no good. -n works
