Is something special needed to enable these qdiscs ? delay was my earlier name, netem is the current one. Netem went in to mainline kernel 2.6.8 (also 2.4.27) > 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". You probably need to build/run newer version of tc see http://developer.osdl.org/dev/iproute2 _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
