Hi, all! I'm trying to use tc to shape traffic sent using libpcap (actually tcpreplay, which is based on libpcap). I'm doing this for a research project.
i have a simple prio scheduler with a default band 2: tc qdisc add dev eth0 root handle 1: prio priomap 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 with two filters attached to it: tc filter add dev eth0 protocol ip parent 1: prio 1 u32 match ip dport 80 0xffff flowid 1:1 tc filter add dev eth0 protocol ip parent 1: prio 2 u32 match ip dport 443 0xffff flowid 1:2 (don't mind the port numbers, they're here just for the example) When sending actual traffic, the filters work and I see the appropriate traffic entering the right class. BUT when replaying captured traffic (with the appropriate port numbers) over eth0 using tcpreplay, all packets end up in the default band 2 as if the filters simply refuse to work. Can anyone suggest a solution? Thanks! - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
