Subject: [LARTC] PRIO not working?
Date: Sat, 13 Apr 2002 21:24:10 +0000 [thread overview]
Message-ID: <marc-lartc-101873313203800@msgid-missing> (raw)
I'm trying to prioritize interactive traffic over other traffic on my 56k
dialup link. I wrote some chains to set the ToS in PREROUTING and OUTGOING,
and I'm using a PRIO queue with three SFQ children:
iptables -A OUTPUT -t mangle -p tcp --dport ftp-data -j TOS --set-tos Maximize-throughput
iptables -A OUTPUT -t mangle -p tcp --dport domain -j TOS --set-tos Maximize-throughput
iptables -A OUTPUT -t mangle -p tcp --dport www -j TOS --set-tos Maximize-throughput
iptables -A OUTPUT -t mangle -p tcp --dport smtp -j TOS --set-tos Minimize-cost
iptables -A OUTPUT -t mangle -p tcp --dport telnet -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport ssh -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p udp --dport domain -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport ftp -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport 5900 -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport imaps -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport 9898 -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport 5190 -j TOS --set-tos Minimize-delay
iptables -A OUTPUT -t mangle -p tcp --dport 6667 -j TOS --set-tos Minimize-delay
tc qdisc add dev $DEV root handle 1: prio
tc qdisc add dev $DEV parent 1:1 handle 10: sfq perturb 5 # interactive
tc qdisc add dev $DEV parent 1:2 handle 20: sfq perturb 5 # throughput
tc qdisc add dev $DEV parent 1:3 handle 30: sfq perturb 5 # lowcost
According to tcpdump, the ToS bits are indeed being set like I asked, but
"watch tc -s qdisc show dev ppp0" shows that everything is going into the
"througput" queue regardless. The only traffic that increments the counter
for the "interactive" queue is post-handshake SSH traffic, and from what
I've read, SSH sets the ToS explicitly. What am I doing wrong?
