In other words, you have the user with the problem log his terminal session to your terminal. No kernel mods necessary, and I beleive that there are terminal session logging programs available for 4.2 BSD (the one I use is for another OS entirely.) You can't take over the user's terminal session with this scheme, but it is available "off the shelf" so to speak, and serves most of the needs. -- Wayne Throop at Data General, RTP, NC !mcnc!rti-sel!rtp47!throopw
