I need to find out what ports are attached to which processes on a Unix machine (HP Itanium). Unfortunately, lsof is not installed and I have no way of installing it.
Does anyone know an alternative method? A fairly lengthy Googling session hasn't turned up anything.
Assuming this is HP-UX? What about the Ptools - do you have those installed? If so you can use "pfiles" to find the ports in use by the application:
pfiles prints information about all open file descriptors of a process. If file descriptor corresponds to a file, then pfiles prints the fstat(2) and fcntl(2) information.
If the file descriptor corresponds to a socket, then pfiles prints socket related info, such as the socket type, socket family, and protocol family.
In the case of AF_INET and AF_INET6 family of sockets, information about the peer host is also printed.
for f in $(ps -ex | awk '{print $1}'); do echo $f; pfiles $f | grep PORTNUM; done
switch PORTNUM for the port number. :) may be child pid, but gets you close enough to identify the problem app.
