- With respect to the 3B2, it is ulimit that is the problem. I can't
- recall the actual details, but its not changable in the kernel in
- the SyV R2. I'm not sure about Sys VR3.x.
-
- AT&T used to put out a monthly support newsletter, and they
- explained how to get around it. The fix was a simple replacement
- for /bin/login. Actually /bin/login would be renamed to /bin/login2
- and the new /bin/login would bump up ulimit, and then call the
- real login program (/bin/login2).
-
- It was a real short program.
-
- As for alternative methods, such as bumping ulimit in /etc/profile,
- that only works for the bourne and korn shells. Also, you need root
- permissions to bump ulimit higher, so you would still need some kind
- of suid program to do it. The filter before login is the only sure way
- to give everybody a higher ulimit (uucp! which does not run a
- shell). Getty is running with root permissions. Login changes to the
- user's id before executing the shell.
-
- I hope this helps. I don't have the source handy, its on my system
- at home (3b2/300). I'll try to dig it up and post it.
