Hi Petar,
This method requires root permissions on Linux to access /proc/*/fd/
*, similar to the 'p' switch in the netstat command:
% netstat -nltp
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
On AIX, you don't need to run as root, but will need read access to /
dev/kmem. You can just add yourself to the system group for example.
There is no Solaris impl yet, what version(s) are you using? I gave
up doing this on Solaris 8 a couple of years ago, but have been
planning to revisit Solaris 10 since OpenSolaris was released.
