Thanks Stef. I'm a little confused now as to whether we have all of the needed files. We are running Redhat 8.0 includes the iproute-2.4.7-5 package. We complied the kernal with all of the QoS switches enabled. I cannot determine if Redhat 8.0 includes the required iproute2+tc package. By searching some web sites we find a tar file with iproute2-2.4.7-now-ss020116-try.tar.gz. Is this already in Redhat 8.0 or do we need to include this also (also is this the latest version). Thanks for the help.

You need the tc binary that can be found in the iproute2+tc package. Stef -- stef.coene@xxxxxxxxx "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.oftc.net
