Enumerating a Windows based PC from a FreeBSD based server

[Paul Hamilton]

Hi,

I am trying to document which managed switch port (HP 4000m), a users PC is
plugged into.  I had thought to use a login script to dump some info into a
MySQL DB, but I am now leaning on scanning the switch, and build up the data
backwards from there.  The info will all end up on a PHP searchable web
page.  I should then be able to track admin logins (does anyone know the
passwd?), have some users given their username and passwd to someone else to
use? Etc.

I have found the SNMP OID's of the IP and MAC addresses and the switch port
number the computer is plugged into.  From a DNS lookup, I can find the PC
name, but how do I find out the current logged in user name on the PC,
remotely from a FreeBSD server?

The GFI LanGuard network scanner is a very informative tool:
http://www.gfi.com/lannetscan/  so having something similar to this on a
FreeBSD server would be great. The utility must of course be scriptable.


Cheers,

Paul
