thanks for the reply

i believe lsof command uses the following file
/dev/kmem

on the stranger part

i tried on server1 - it was working fine and i could all the information that i needed
and when i tried it on server2 - it was showing permission denied

i checked the permissions for the file on either of the servers and it was the same

could you please explain why its show different behaviour.

I do need one more clarification.
Ports indicating LISTEN status are the ones picked by the process and opened to accept connections right?

There is no list of acceptable ports which could hereby be opened and connected.

I think i am making myself clear. Kindly revert if i had to explain my question in detail.

Thanks

NAME
gentest - Run random generic SMB operations against two SMB servers and show the differences in behavior SYNOPSIS
gentest {//server1/share1} {//server2/share2} {-U user%pass} {-U user%pass} [-s seed] [-o numops] [-a] [-A] [-i FILE] [-O] [-S FILE] [-L] [-F] [-C] [-X] DESCRIPTION
gentest is a utility for detecting differences in behaviour between SMB servers. It will run a random set of generic operations against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets. This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers. OPTIONS
-U user%pass Specify the user and password to use when logging on on the shares. This parameter is mandatory and has to be specified twice. -s seed Seed the random number generator with the specified value. -o numops Set the number of operations to perform. -a Print the operations that are performed. -A Backtrack to find minimal number of operations required to make the response to a certain call differ. -i FILE Specify a file containing the names of fields that have to be ignored (such as time fields). See below for a description of the file format. -O Enable oplocks. -S FILE Set preset seeds file. The default is gentest_seeds.dat. -L Use preset seeds -F Fast reconnect (just close files) -C Continuous analysis mode -X Analyse even when the test succeeded. VERSION
This man page is correct for version 4.0 of the Samba suite. SEE ALSO
Samba AUTHOR
This utility is part of the Samba[1] suite, which is developed by the global Samba Team[2]. gentest was written by Andrew Tridgell. This manpage was written by Jelmer Vernooij. NOTES
