/usr/sbin/tc is part of iproute2 and is used to setup traffic control settings. (man tc) As far as I know this is a known bug and has been fixed via YOU a while ago, please install updates and try again. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

First question, see: http://lartc.org/lartc.html with tc you can shape ip-traffic, give different priorities to ip-traffic from/to different machines based on address/port. It even has tools for simulating all kinds of network problems, like latency, bandwith-problems, missing or duplicating packets, re-ordering frames. Together with the less-known features of iptables, it makes a very, very powerfull toolset. url above is one of the very regular referenced howto's, not only about tc, but all sorts of network-tricks (tunneling, multiple internet-providers). Secondly: from the distro i initially installed ../distribution/11.0/oss/suse/x86_64/iproute2-2.6.23-75.1.x86_64.rpm afaics there were no updates for iproute2, or anything like tc* Only patch i've not installed (yet) is kernel: 2.6.25.20-0.1, because we are not fond of going down... hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Are you planning to do any traffic shaping? Let's share our experiences - I've been running wondershaper for about a year. /Per -- Per Jessen, Zürich (16.3°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
