List of active users, logged in with gdm

[Laszlo Nagy]

  Hi,

I would like to get the list of the users who are actively logged in 
remotely with gdm, along with their IP address. The commands 'w' and 
'users' does not work. What is the right command to get this list?

uname:

FreeBSD test.dyndns.org 6.2-RELEASE-p7 FreeBSD 6.2-RELEASE-p7 #4: Wed 
Aug 29 14:01:04 CEST 2007     
gandalf at test.dyndns.org:/usr/obj/usr/src/sys/DARKSUN  i386

(The computer is an application server, serving applications to diskless 
machines with gdm + gnome.)

Thanks,

   Laszlo
