I'm trying to configure an interface using a batch script and tc and no matter what I try, Zentyal 2.0.3 always reports 'File exists':
eg
tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540
RTNETLINK answers: File exists
I've tried all the variants in the book and nothing seems to work...
A vanilla Ubuntu 10.04 installation has no problems with this.
Is it possible that someone could give me some pointers as to why this issue crops up under Zentyal?
