| |
Hello, I've been trying to rate limit my incomming connections, and, as I understand, I can do that only with ingress. So I did a litle test:
tc qdisc add dev eth1 handle ffff: ingress tc filter add dev eth1 protocol ip parent ffff: prio 50 u32 match ip src \ 204.152.189.116 police rate 128kbit burst 10k drop flowid :1
tc qdisc list dev eth1 qdisc ingress ffff: ----------------
tc filter ls dev eth1 parent ffff: filter protocol ip pref 50 u32 filter protocol ip pref 50 u32 fh 800: ht divisor 1 filter protocol ip pref 50 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid :1 match cc98bd74/ffffffff at 12
The outside interface is eth1.
After I do this, any connection to ftp.kernel.org doesn't work.
Attached is a dump of a connection try to ftp.kernel.org.
Am I doing something wrong here or the problem comes from somewhere else ?
