Hi, all: I want to use "profile" to simulate delays according to a empirical delay distribution ( the "profile" argument can be found in http://fuse4bsd.creo.hu/localcgi/man-cgi.cgi?ipfw+8) I use the following command lines and distribution.txt, and find that these command lines seem not to function. when I ping 9.161.148.72, the RTT<1ms My question is 1) can "profile" be used in windows platform 2) are there any problems in my procedures? my command lines are: ipfw pipe 1 config profile distribution.txt ipfw add 100 pipe 1 ip from 9.161.150.55 to 9.161.148.72 -------------------------------------------------------------------------------------- if I input: ipfw pipe show the result is: 00001: unlimited 0 ms burst 0 profile: name "distribution" loss 0.850000 samples 100 q131073 50 sl. 0 flows (1 buckets) sched 65537 weight 0 lmax 0 pri 0 droptail sched 65537 type FIFO flags 0x0 0 buckets 0 active the content of distribution.txt is: name distribution samples 100 loss-level 0.86 prob delay 0 200 # minimum overhead is 200ms 0.5 200 0.5 300 0.8 1000 0.9 1300 1 1300 #configuration file end
