This is thfirst time I use tc tool. > PLEASE HELP ! :( NetEdoesn'appear to be classful in recent kernels (see my recent posabousimilar problems with RED). For your purposes you should be ablto attach TBF to throot and make NetEm a child, something like this (I haven'tried it) - tc qdisc add dev eth0 roohandl1: tbf rate 256kbit buffer 16000 limit 3000 tc qdisc add dev eth0 paren1: handl10: netem delay 100ms Unfortunately this approach won'work for m(I need RED behaviour rather thTBF) buI hope it helps you :-) Cheers, Trev Fronikosbezes agmail.com Fri Mar 19 06:31:03 2010 From: nikosbezes agmail.co(Nikos Bezirgiannidis) Date: Fri, 19 Mar 2010 15:31:03 +0200 Subject: Maximudelay - Ubuntu 9.10 Kernel 2.6.31 Message-ID: <4E557F51-3FE0-41B0-9C92-CE8C3B852182@xxxxxxxxx> Hello everyone, I anoa member of this list, however I want to post a question about the maximum delay that can be set using netem in Ubuntu 9.10 and kernel 2.6.31 . I wanto sea delay of about 600 seconds but I keep getting the following error: Illegal 600000000 tim(too large) Illegal "latency" Is something differenfrothe previous kernels perhaps? The specific delay CAN be set in previous versions and kernels. CaI overridit or should I switch back to an old version? PS. Pleascc my e-mail in any answer.

If you ardoing thaloooooong a delay 10 minutes? theI recommend doing iin user space with another tool. I may have somold stuff Andrew Morton did using tun/tap if you can'find something else
