I hope I'm posting to the correct list here, I thought I'd make certain before possibly making my first post to freebsd-bugs. I've been using Dummynet for the last 3 weeks or so on a machine at the new local cybercafe which we set up, limiting 17 stations to 64Kb/s and one to 128Kb/s. It's been working - to a point. Usually around 3-4PM each day, when the box starts being used more, it crashes, dead. Sometimes it manages to reboot itself, others it cannot. It's also crashed once when I stopped the Apache httpd, and once when stopping Squid (2.1 RELEASE). Sadly, I'm not anywhere near it when it goes down, so I can't see any panic messages, nor are they logged to the /var/log/messages file - only a "Warning: / was not properly dismounted" is the only way I know when it crashed. At first, I thought this was a problem with the machine, and as we were just about to order a replacement box, I've tested it out on a P2-233 here at work. It's a moderatley heavily hit HTTP server, and after 5 mintues of dummynet limiting to 256Kbit/s, it crashed. Both machines were installed as follows: 1) Main install over FTP install system 2) Apache (& Squid for the cybercafe) installed. 3) Recompile the kernel and comment out unneeded drivers, etc. I've put the config file up at http://www3.shellnet.co.uk/shellnet/SHELLNET-1.1 if anyone would like to look at it. 4) Reboot, and add IPFW/dummynet rules, for example: ipfw pipe 131 config bw 64Kbit/s delay 30 ipfw add 131 pipe 131 ip from 193.133.229.131 to any ipfw add 131 pipe 131 ip from any to 193.133.229.131 And about a day later, a crash :(. Running kernel.GENERIC without the IPFW rules, we had an uninterupted uptime of 7 days before we tried the old kernel again, which crashed the next day. I've tried recompiling squid/apache, anything for the new kernel, but nothing seems to work. Is this a known problem, and is there a patch available? Thanks for reading my drivel all :) Steven Fletcher - steven@shellnet.co.uk Shellnet - http://www.shellnet.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
