Hi ,
I have VmWare running on Windows XP and I have installed
Fedora Core 6 as the OS. iptables et al are working perfectly but
when it comes to traffic controller (tc), it just does not seem to be
obeying any of the rules...

For example when I gave
$ tc qdisc add dev eth0 root delay 100ms
the command is accepted without error, but does not reflect in the
ping response..
I tried ping with -I to bind the eth0 interface, but still did not
give me the desired results.

The same command is working on a pure Fedora Core 6 desktop..

Can someone guide me how I can debug tc or if I am missing any steps.

Thanks,
Sandeep

you are missing netem

tc qdisc add dev eth0 root netem delay 100ms

I've not tried tc on vmware though, so you may hit other problems.
