Iproute allows you to route packets according to their iptable's MARK

Especially if you have a dsl router in a ethernet subnet.
My subnet consists of three hosts, two of them are bintec routers who do
the dsl stuff. They are reachable, even if the DSL Line is gone.
How would U check that?
I just want to get the most out of both lines at the same time. My
internal network has two services (http, imap) that need require
port- forwarding from the router. Other than that the internal
network is used for surfing the web, ssh, ftp, irc, p2p cients.
Your services can listen on both interfaces, no problem with that...
you can have load balancing on those links with multiple DNS records
(though that's not a good thing (tm).
Use the iptables MARK to use both at the same time, and the

Re: [LARTC] HTB rate miscalculation
One problem appeared. Htb seems to miscalculate the bandwidth for classes with greater rates. For rates below 2Mbit there is almost no difference between the configured and the measured rate. For large ones the problem starts. My root class has 10Mbit rate and when the interface has heavy trafic the measured bandwidth coudn't get more then 8.5Mbit. # tc -s class show shows that the root class has about the 10Mbit, but the link stats shows mutch less. The solution was to put the htb ceil on about 12Mbit. Then I can get to the 10Mbit. When using CBQ I didn't have this problem. Is there any parameter that I can change to correct the rate calculation? Any one has similar problem? What counters are you using to measure? Does it do the same if you test with a single tcp stream and a very simple setup like - tc qdisc add dev eth0 root handle 1:0 htb tc class add dev eth0 parent 1:0 classid 1:1 htb rate 10mbit tc filter add dev eth0 parent 1:0 protocol ip u32 match u32 0 0 flowid 1:1 Andy. I've done more tests, in fact there is a difference in the measure. The rate measured by htb class, iptraf and iptables show very similar numbers. The rate measured using SNMP ifInOctets and ifOutOctets (snmpget, ddrtool and mrtg) show rates about 20% less than htb. Why this difference? Not sure - I can get netperf, htb counters and polling ifconfig counters every second to agree and show correct rate with the simple case above. I don't have snmpget to test. Andy. The difference is for sure on snmp counters, that's what mrtg an ddrtool use. Getting counters for eth0 (should have snmp daemon running): ifInOctets=`/usr/bin/snmpget -v1 -c snmppass host .1.3.6.1.2.1.2.2.1.10.2 | cut -f4 -d:` ifOutOctets=`/usr/bin/snmpget -v1 -c snmppass host .1.3.6.1.2.1.2.2.1.16.2 | cut -f4 -d:` Marcus ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

There is no comprehensive docu around which could e.g. used for

Re: [LARTC] how to guarantee 1/numflows bandwidth to each flowdynamically
Scott Mcdermott wrote: I am looking for a simple way to guarantee to each flow going through my traffic control point 1/numflows of bandwidth. I thought using SFQ would do this effectively but it appears to be quite unfair: a very high speed download that fills the pipe easily starves smaller flows to the point where it becomes unusable (especially if they are at all interactive) Because numflows is dynamic, I'm not sure how I would have the bandwidth allocated to each flow change dynamically and automatically as flows are added and removed. Anyone have an idea how to implement this? Thanks. Perhaps you should look at esfq rather than sfq. esfq lets you specify quantum in bytes, depth in flows, limit in packets, and a source or dest hash. Don't apply any sfq to what Wondershaper calls interactive. You need to match esfq to the kernel version; 2.6 uses a different esfq than 2.4. -- buck ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
