I have three Squid machines working together as a cache array. I used Dummynet to control the inter-cache bandwidth.
My three squid is 10.12.0.1, 10.12.0.2 and 10.12.0.3 I used the following commands to create pipes in each squid For example, in Squid1: ipfw add pipe 1 IP from 10.12.0.1 to 10.12.0.2 out ipfw add pipe 2 IP from 10.12.0.1 to 10.12.0.3 out ipfw pipe 1 config bw 10Mbit/s queue 75Kbytes ipfw pipe 2 config bw 10Mbit/s queue 75Kbytes I have another program to change the bandwidth of each pipe every half an hour, with a lot of traffic going through the caches at the same time. So that the configeration for a pipe can change FROM: ipfw pipe 1 config bw 10Mbit/s queue 73Kbytes TO: ipfw pipe 1 config bw 2Mbit/s queue 25Kbytes Then in very short time, the machine is dead. I think the problem might because of the setting of "queue". But I don't know how much should be correct. I was using "bw x Mbit/s queue 6*x+13 Kbytes". Oh, when bandwidth change from 5M to 3M ,or 8M to 5M (smaller difference), the machines will run just fine with my 6*x+13 setting. Only steep jump like from 8M to 2M will always cause death. Please help me out!!! This is emergency!!!! _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
