[LARTC] Shaping and forward

2005-02-08 Thread Kenneth Kalmer
Lartc readers I have a peculiar problem with shaping and firewalling. My tc rules work great, below is a smaller version: #Root tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 100 #Root Class tc class add dev eth0 parent 1: classid 1:1 htb rate 1024kbit quantum

If nano-howto doesn't work, you should consult my different approach: http://selab.edu.ms/twiki/bin/view/Networking/MultihomedLinuxNetworking the tutorial comes with a completed daemon so you have a handy solution http://selab.edu.ms/twiki/bin/view/Networking/RoutesKeeperProject Mailing List

Re: [LARTC] please guide me ...with regard to multipath dynamic routing in case of link failure

2005-02-08 Thread Nguyen Dinh Nam
So you have to write a daemon to ping the remote gateway, and if ping fails, the daemon will remove that nexthop from the multipath route. The dead gateway detection patch can't help you in this case. That's why I created this project, download and run it, and everything solved, it's lack of

[LARTC] TCP window based shaping

2005-02-08 Thread Ed Wildgoose
Does anyone have any pointers on how other people have implemented tcp window adjustment to do bandwidth shaping? Granted the basic idea is to set the window size to be RTT * bandwidth, but a quick squiz at google turns up mostly papers on how to implement this at the sender end with a view to

[LARTC] A question on the iproute default queues

2005-02-08 Thread Ioannis C Avramopoulos ([EMAIL PROTECTED])
Hi, when iproute is installed then the default queue that it is giving to an interface is pfifo_fast. I would like to ask whether it is possible to disable this feature and rather have the kernel give by default to an interface the queue that it would give if iproute hadn't been installed.
