Depending on the kernel version and which options you compiled it with, though, there are a lot of pseudo-files under /proc which contain the kind of information you're seeking. In some cases, you can write stuff to these pseudo-files to change kernel parameters on the fly. (In other cases, you'll have to edit kernel source code and rebuild the kernel to change them.) A good example: in order to forward packets between network interfaces under a 2.2.x kernel, you have to run this command: echo 1 >/proc/sys/net/ipv4/ip_forward Unfortunately, I don't have any references for additional reading. :-( -- Greg Wooledge | Distributed.NET http://www.distributed.net/ wooledge@kellnet.com | because a CPU is a terrible thing to waste. http://www.kellnet.com/wooledge/ |
