2.2 ipchains stuff can't do uid-based filtering/shaping/accounting, netfilter can. if you don't want to run 2.4test kernels, wait till 2.4 is stable or use freebsd (i know this is a linux mailing-list, but fbsd has it in stable for some time, for linux it's (still) unstable, so if you don't want to run unstable code, consider freebsd you should read the Adv-Routing-HOWTO, it's about 2.2/2.4 kernel routing using iproute2 (apt-get install iproute). it's quite complex, but will be able to do it together with 2.4 firewalling code. possibly you only need iptables, first read netfilter docs, if you don't find a solution with only netfilter, read adv-routing howto and use iproute2 together with netfilter look for iptables info at http://netfilter.kernelnotes.org/unreliable-guides/ for adv-routing howto in /usr/share/doc/HOWTO/en-txt/Adv-Routing-HOWTO.txt.gz or in /usr/share/doc/HOWTO/en-html/Adv-Routing-HOWTO.html (if doc-linux-text/html installed), else http://linuxdoc.org sorry about my confusing explaination, but i'm not an expert in cbq/netfilter, so you've to findout the details yourself > > CPU & RAM would also be nice, but I assume linux won't let a user > > totally take over the machine's resources with default options. > > No, see /etc/security/limits.conf for doing this.
