this is limit's output at one of our university servers:
>limit
cputime unlimited
filesize unlimited
datasize unlimited
stacksize 8192 kbytes
coredumpsize 1000000 kbytes
memoryuse unlimited
descriptors 256
memorylocked unlimited
maxproc 256
openfiles 256
fork bomb won't do much with limited maxproc etc..
under Debian GNU/Linux you set it in /etc/login.defs:
#
# Login configuration initializations:
#
# ERASECHAR Terminal ERASE character ('\010' = backspace).
# KILLCHAR Terminal KILL character ('\025' = CTRL/U).
# UMASK Default "umask" value.
# ULIMIT Default "ulimit" value.
#
# The ERASECHAR and KILLCHAR are used only on System V machines.
# The ULIMIT is used only if the system supports it.
# (now it works with setrlimit too; ulimit is in 512-byte units)
#
# Prefix these values with "0" to get octal, "0x" to get hexadecimal.
#
ERASECHAR 0177
KILLCHAR 025
UMASK 002
ULIMIT 2097152
