Logging out idle users?

[Michel Fingerhut]

Hello world,

I am looking for a program that would logout idle users on terminals/virtual
terminals, and would also run under ultrix... (specifically ultrix/risc, >= 4.0)

I know of untamo.  Unfortunately, untamo sends a vhangup which causes (under
ultrix) some of the processes to detach from the line and start wildly looping
and eating cpu time (most notably rlogin).

Please respond by mail, if at all possible.  I will summarize.
