That file should have comments in it if its a recent Linux distro. And its PAM* that typically does all this stuff for you now. *PAM == Pluggable Authentication Module (but does way more) Edited by folkert Dec. 3, 2008, 04:00:15 PM EST Expand All History

Post #300,583 by crazy 12/3/08 3:59:53 PM Reply	Clueless, but When I went from Solaris to Linux, there was a bunch of stuff that only worked using RH (or Centos) enterprise large system kernel. Not that these settings/patches can't be anywhere else in another dist, just it was configured for big iron already. You might want to give it a shot.
Post #300,585 by folkert 12/3/08 4:03:14 PM Reply	Using a "Debian" based distro... Like Ubuntu == "server" kernel required. Debian uses "-bigmem" kernel for these functions. Unless you are using 64-bit. Then it doesn't matter. CentOS/RHEL you have to use the "ELhugemem" kernel now a day, unless you are using 64-bit again.
