Hi, I'playing with thcorrupt feature of netem. It seems that the corruption only happens in the payload, and never in the UDP/IP/MAC headers (i.e. I never get a whole packet knocked out by a corrupted header). Is ipossiblto extend corruption to the headers ? (I guess it depends how close to the wire the TC queues intercept the frames). If iisn'possible, I guess the solution is to combine the corrupt function with the drop feature, with a bit of statistical crunching to make sure the effect is equivalent to the BER on the wire.

I haven't had a lot of luck, though. Is there anyonouthere that cagivme insight as to how prio bands works and what its entries actually represent. Through experimentatioI havfound that the highest number that can be used for this entry is 16.

What you want is th"iproute2" package, which contains th"tc" command. I'd bet thacentos has iinstalled by default. Try running "tc qdisc show" froa terminal. If thaworks, you have everything you need. You cathen try somof the examples at http://www.linuxfoundation.org/en/Net:Netem Frobala.linux agmail.com Thu Mar 19 12:09:33 2009 From: bala.linux agmail.co(Balakrishnan B) Date: Fri, 20 Mar 2009 00:39:33 +0530 Subject: Local Traffic -> IFB -> ETH0 Message-ID: <b111d9eb0903191209l6c46b373s33b03cf860ec9d6d@xxxxxxxxxxxxxx> Hello All, Casomone please guide me in setting up this environment ?
