I have tried with SFq but is doesnot yeild my requirement.. Thanks, Namitha. If you can't think of a way to turn a connection into a class then search the archive for perflow - someone once started a qdisc to do this.

With CONTRACK/CONNMARK you can get an individual mark per connection, then you will need to allocate dinamic qdisc/class/filter to match that mark. Problems that i see: -do not know if there is an easy way to know wath mark was assigned, but you can allways 'use the source' -do not have experience adding and deleting qdisc/class/filter in milisecond basis. Not shure at all, but i think that is possible. -- Luciano ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Devik, Thanks for that...now I have to do some thinking..

So that you will end with all classes busy. You would have to write it yourself probably - extend iptables connection tracking to maintain table of classids and select classid for new connection and return it when conn is deleted.

Re: [LARTC] HTB and per-connection bandwidth allocation
hi! imho there's an iplimit-patch (at patchomatic) - you should be able to limit the numer of connections to 100 with this... just a guess Sebastian -- Sebastian 'spax' Pape | Better to remain silent and be thought a fool mailto: [EMAIL PROTECTED] | than to speak and remove all doubt. gpg: http://p-a-p-e.de/gpg.asc | --- Do you want to know more? http://www.p-a-p-e.de/ --- ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
