Kristian asked, " Is there a way to see the IP-address on all users
currently logged-on?"

I know this is a work around but if you logon as MANAGER.SYS (I tried
this not logged on with SM capability and got an error) and do a LISTF,8
on your logon UDC (or any SYSTEM UDC) it will show you everyone logged
on. It will show you the spool ID of all jobs.
