This simple perl script was designed under FreeBSD, and, right now, is limited to it. It provides a simple way of determining and directing administrators in what has to be done to get IPC working, and configured. Usage: ipc_check.pl - simply checks for semaphores and shared memory being enabled - if one or other is not enabled, appropriate "options" are provided to get it compiled into the kernel ipc_check.pl -B <# of buffers> - checks to see if there are sufficient shared memory buffers to run the postmaster with a -B option as provided - if insufficient buffers are provided, appropriate 'sysctl' commands, and instructions, are provided to the administrator to increase them
