Hi all, I am trying to solve a tiny problem that is trivial to solve using dummynet (FreeBSD). I just want to add a delay of 50ms to each outgoing packet from an interface. This is to simulate a large pool of multiple modem users so I also need to add b/w limits etc (which seems to be easy to do). >From the mailing list I could fine 2 qdiscs that can simulate latency : "delay" & "netem". Neither of them is working on my setup though ( Fedora core2 [2.6.5] or RHEL 3.0 update 2 or gentoo [2.6.8] ). Is something special needed to enable these qdiscs ? I tried applying the patch (http://www.uwsg.iu.edu/hypermail/linux/net/0403.2/0019.h tml) and recompiled the kernel but the tc command returns "RTNETLINK answers: Invalid argument". What am I doing wrong ? Thanks much, -ansh _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
