I had a little free time so I tried to fix some of the portability
problems with the "top" program ("top" is sort of a real-time "ps uax").
I've got it working on
Ultrix 4.0 Vax
Ultrix 4.0 RISC
Ultrix 3.1D RISC
Ultrix 3.0 Vax
The code has been tested on an SMP Vax (dual processor) but not
on an SMP RISC system, although I don't expect any problems. Also,
the sources have not been tested for portability back to non-Ultrix
systems (I tried to avoid breaking anything, but ...).
This is version 2.1 of "top"; there are more recent versions floating
around, but this is the one that I had.
Sources:
anonymous FTP to gatekeeper.dec.com
"type binary"
"get pub/DEC/top.tar.Z"
Be careful: as the README file says
CAVEAT: version 2.0 of top has internal commands that kill and renice
processes. DO NOT INSTALL TOP AS A SETUID PROGRAM, or you will open up a
big security hole since top makes no process ownership checks on its own.
Note that it is still safe to install top as a set group-id program, since
group-id has no bearing on who can renice or send signals to what
processes.
and on a 4.0 system you'll have to install "top" as setgid for group
"kmem" if you want non-super-users to be able to run it.
This software is not in any way supported or guaranteed by Digital
Equipment Corporation, of course.
