Using the command: sysctl -p as per man pages fails, thus: [root@raptor /etc]# uname -a Linux raptor 2.2.12-20smp #1 SMP Mon Sep 27 10:34:45 EDT 1999 i686 unknown [root@raptor /etc]# ls -l sysctl.conf -rw-r--r-- 1 root root 24 Feb 28 09:49 sysctl.conf [root@raptor /etc]# cat sysctl.conf kernel.shmmax=491520000 [root@raptor /etc]# sysctl -p error: unable to open preload file '/etc/sysctl.conf' [root@raptor /etc]#
This is fixed in the procps in rawhide...
