Hi all, used the very basic command 'tc qdisc add dev eth0 root netem delay 10ms' on my box and 'ssh'ed to another box. For a little traffic I did a 'find /', after a short time the output stopped. I had to bring the interface down and up again to solve the problem (for a short time only;-). I saw this behaviour in the kernels 2.6.12.3 and 2.6.13-rc4 on 2 different PCs. 2.6.8(.1) was ok and worked as espected on both machines. If more information is needed to track it down please give me a hint what is necessary.
