I guess that's because your router does masquerading so source
addresses are changed , and filters don't match.
Please please help, i've lost lots of sleep over this. Here's my set-up: 4 computers on a LAN in my house, having IPs 192.168.0.7, 192.168.0.50, 192.168.0.52, 192.168.0.58.A router/linux-box (which runs the shaping/tc_commands), which is the default gateway of the 4 machines: 192.168.0.1. It masquerades the internet connection.Internet connection: ADSL PPPoE. The ADSL modem is connected to eth0 of the router, and PPPoE makes ppp0. eth1 is the LAN. Yes, kernel is compiled correctly (has advanced router option, patched with HTB, etc). Here's my script. Essentially what I want to do is give each of the 4 ppl a fourth of the bandwidth, giving myself a higher ceiling because I use more bandwidth than they do. ---------------------------------tc qdisc add dev eth1 root handle 1: htb default 14 tc class add dev eth1 parent 1: classid 1:1 htb rate 12kbps ceil 12kbpstc class add dev eth1 parent 1:1 classid 1:10 htb rate 4kbps ceil 10kbps burst 1k prio 1tc class add dev eth1 parent 1:1 classid 1:11 htb rate 4kbps ceil 7kbps burst 1k prio 2tc class add dev eth1 parent 1:1 classid 1:12 htb rate 4kbps ceil 7kbps burst 1k prio 2tc class add dev eth1 parent 1:1 classid 1:13 htb rate 4kbps ceil 7kbps burst 1k prio 2tc class add dev eth1 parent 1:1 classid 1:14 htb rate 1kbps ceil 10kbps burst 1k prio 2
# use SFQ (stochastic fair queueing) for everything
tc qdisc add dev eth1 parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev eth1 parent 1:11 handle 11: sfq perturb 10
tc qdisc add dev eth1 parent 1:12 handle 12: sfq perturb 10
tc qdisc add dev eth1 parent 1:13 handle 13: sfq perturb 10
tc qdisc add dev eth1 parent 1:14 handle 14: sfq perturb 10 # matchings
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip src 192.168.0.7/32 flowid 1:10
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip src 192.168.0.58/32 flowid 1:11
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip src 192.168.0.50/32 flowid 1:12
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip src 192.168.0.52/32 flowid 1:13-------------------------------------- The PROBLEM: no matter how hard I try, NO packets EVER get onto any flow but the default, 1:14. Eg. my computer (192.168.0.7) can send many packets thru the gateway, and none of them get put on flow 1:10 like they should, they all go onto 1:14, the default. Why? Add'l QUESTIONS: Which interface should I be using?! Ideally i'd like to use ppp0, but I guess I can't because i'm masquerading? Therefore I should use eth1, the internal lan-side ethernet card? Also, have I got the SFQ tied in right? Perhaps my matchings/filters should use 10:something instead of 1:10 etc? ... I've tried MARKing packets with IPtables, that doesn't work either. Is that a better method ? (I feel that it isn't, right now...) Lots of questions eh?! All answers appreciated! Thanks, Tim Carr
