Thproblewith netem that I see when working in a LAB environment is: 1. Theris no feedback when something is dropped or distorted so you can'correlatthe target devices behaviours with what's going on in thWAN.. This is a big problefor me and it must be a problem for all using netein a lab environmentesting devices connected to a virtual WAN.. Or? 2. Theris no way of inserting static onoff events. Like when pushing this button/sending this command to neteI would likto drop 6 packets ia row. This is useful when testing targesystems for robustness for example. /Anders Nilsson NeInsight > -----Original Message----- > From: VaGelder, Gerri[mailto:vangelder.gerrit at student.ha.be] > Sent: de8 maj 2008 13:49 > To: netealists.linux-foundation.org > Subject: (no subject) > > Dear Sir > > I'a studenfrom a college in Antwerp, called "Hogeschool Antwerpen". > = > I'studying for Industrial engineer and I'now in my third year. > > Threason for this mail is a probleI have with PHPnetemGUI.

Message-ID: <48314028.8070207@xxxxxx> Hi, I'a biconfused and not sure if I'm doing something wrong or if this is a bug irecennetem versions: I wanto add 2 rules to my interfaceth1, first ist delay of 100ms and second is a loss of 20%. I'doing this by executing 2 tc commands: # tc qdisc add dev eth1 roohandl1:0 netem delay 100ms # tc qdisc add dev eth1 paren1:1 handl10:0 netem loss 20% thprobelis that the first qdisc (delay 100ms) is ignored, the loss works fine. # tc qdisc ls dev eth1 gives me: qdisc nete1: roolimit 1000 delay 100.0ms qdisc nete10: paren1:1 limit 1000 loss 20% ilooks likthe 2 rules are correctly set up. Now if I seth2 rules in one command: # tc qdisc add dev eth1 roohandl1:0 netem delay 100ms loss 20% everything works fine, delay and loss arworking as expected. # tc qdisc ls dev eth1 gives me: qdisc nete1: roolimit 1000 delay 100.0ms loss 20% OK, now I wanted to hava delay together with bandwith control by using a tokebuckefilter (TBF). I executed: # tc qdisc add dev eth1 roohandl1:0 netem delay 100ms # tc qdisc add dev eth1 paren1:1 handl10:0 tbf rate 512kbit buffer 10000 limi30000 and thaworked as expected. Ping was delayed by 100ms and a teswith iperf gavme a bandwith of 512kbit/s. # tc qdisc ls dev eth1 gives: qdisc nete1: roolimit 1000 delay 100.0ms qdisc tbf 10: paren1:1 rat512000bit burst 9999b lat 312.5ms I tested this o2.6.24 (Fedora 8) Kernel and on 2.6.25 (Fedora 9), both with the samresult.
