Where are maxproc, etal system params under Linux?

Where are maxproc, etal system params under Linux?

Post by Marc Slayto » Thu, 19 Feb 1998 04:00:00

Sorry for that last post -
I'm using news over a very slow connection.

Anyhow - my question is this:
Suppose I'm a systems administrator and I want to increase the maximum
number of allowed user processes on a Linux server.

OR - the maximum number of system processes

OR - the maximum number of IP connections allowed.

These parameters and other typical kernel tweaking seem to be
missing from the documentation. I already know how to do this
under BSD and SysV.

Can anyone enlighten me?

BTW - I'm using RedHat 5.0, and I already know how to compile/install
Linux kernels.  I've checked the /usr/docs files, as well as browsed
through headers such as those in /usr/src/linux/include/asc/param.h ,
but can't seem to find any well-documented roadmap of these
header parameters to help.
