Hello Zealous Joel! : I was using redhat bfore and tc was working fine : but when i migrated to slackware : my verison is slackware 8.1 What release of iproute2 are you using? (I like the most current release, now-020116-try [1], and have had good luck with it.) : when i m giving below command. : root@xxxx:~# tc qdisc add dev eth1 : RTNETLINK answers: Invalid argument This looks like a rather incomplete command to me. What sort of qdisc are you adding? If you are attempting to use HTB and are using the stock iproute2 distribution (see [1]), then you'll need Devik's patch. You can find this patch in the HTB distribution [2]. : Y it is giving me this error RTNETLINK ANSWERS: INVALID ARGUMENT ... Probably because you didn't feed it enough boiled brambles. Software is terribly willful despite its inanimateness, you know. Ciao for now, -Martin [1] ftp://ftp.inr.ac.ru/ip-routing/iproute2-2.4.7-now-ss020116-try.tar.gz [2] http://luxik.cdi.cz/~devik/qos/htb/v3/htb3.6-020525.tgz -- Martin A.
