"Shell Fork Bomb Protection"
Description:
Fork Bomb Protection will prevent users with terminal access (ssh/telnet) from using up all the resources on the server. Unchecked resource allocation can potentially lead to a server crash.
It is recommended that this protection be enabled for servers providing terminal access.
The only thing I discoverd if enabled is the following entry in /etc/profile (if disabled, there is no ulimit set)
#cPanel Added Limit Protections -- BEGIN
#unlimit so we can run the whoami
ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null
LIMITUSER=$USER
if [ -e "/usr/bin/whoami" ]; then
LIMITUSER=`/usr/bin/whoami`
fi
if [ "$LIMITUSER" != "root" ]; then
ulimit -n 100 -u 20 -m 200000 -d 200000 -s 8192 -c 200000 -v 200000 2>/dev/null
else
ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null
fi
#cPanel Added Limit Protections -- END
