Hi, all, I am a newbee to tc. I want to create a filter on port 2323, but got an error like this. Anyone can help me? [jason@localhost network]$ sudo tc -s qdisc ls dev eth0�qdisc mq 0: root� Sent 1483890 bytes 3617 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
[jason@localhost network]$ sudo tc filter add dev eth0 parent 0: protocol ip u32 match ip dport 2323 0xffff flowid 1:0

tc is extremely picky and hard to debug with such lovely specific errors. (<= blatant sarcasm)

This is an example TC script I used to use. This has port matching included.
It's been a few years since I looked at tc (this comes from a rhel3 server)
But IIRC it worked fine.
