Hi, I''d like to create a high latency link between 2 machines ( more than 700 ms round trip) for simulation purpose. Is it possible to do that with linux qos management software ? thanks Pascal OFFREDO ___[ Pub ]____________________________________________________________ Inscrivez-vous gratuitement sur Tandaime et gagnez un voyage à Venise www.Tandaime.com/index.php?origine=4 Tandaime, et la vie vous sourit ! _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Check latest rc from 2.4 or 2.6. It contains sch_delay that can do this. You also need: http://developer.osdl.org/shemminger/tcp/iproute2-delay.tar.bz2 Example: tc qdisc add dev eth0 root delay latency 25ms rate 100mbit Good luck!> > > thanks > > Pascal OFFREDO > > > ___[ Pub ]____________________________________________________________ > Inscrivez-vous gratuitement sur Tandaime et gagnez un voyage à Venise > www.Tandaime.com/index.php?origine=4 Tandaime, et la vie vous sourit ! > > _______________________________________________ > LARTC mailing list / LARTC@mailman.ds9a.nl > http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/ >--- Catalin(ux) BOIE catab@deuroconsult.ro _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
That''s great! now I can use the uid match of iptables, together with MARK, to make really good shapers for some people.... like "tc qdisc add dev eth0 root delay latency 2000ms rate 1k", I think I will use it for that guy who tries to be funny all the time. users will long hair, a nice dress and smiling get the full 10Mb.. :) On Fri, 26 Mar 2004 13:39:26 +0200 (EET) Catalin BOIE <util@deuroconsult.ro> wrote:> On Fri, 26 Mar 2004, Pascal OFFREDO wrote: > > > Hi, > > > > I''d like to create a high latency link between 2 machines ( more than > > 700 ms round trip) for simulation purpose. > > > > Is it possible to do that with linux qos management software ? > > Yes, it is possible. > Check latest rc from 2.4 or 2.6.
