Need to reboot often - noob help
I've been having problems with my pfsense box, but I need help debugging the problem.
Problem: every 2-8 hours I will suddenly stop being able to reach certain sites. eg. amazon.com ebay.com. But, I'll do fine browsing other sites. There doesn't seem to be a rhyme or reasons as to which sites.
Today when this happened I ran a traceroute.
$ traceroute amazon.com traceroute: unknown host amazon.com $ traceroute google.ca traceroute: unknown host google.ca $ traceroute google.com traceroute: Warning: google.com has multiple addresses; using 188.8.131.52 traceroute to google.com (184.108.40.206), 64 hops max, 52 byte packets 1 [REMOVED for my privacy] (192.168.1.1) 0.773 ms 0.680 ms 0.588 ms 2 [REMOVED for my privacy] 14.264 ms 14.437 ms 15.430 ms 3 [REMOVED for my privacy] 16.331 ms 15.693 ms 17.154 ms 4 [REMOVED for my privacy] 19.420 ms 18.640 ms 18.914 ms 5 * * * 6 220.127.116.11 (18.104.22.168) 20.229 ms 22.214.171.124 (126.96.36.199) 19.417 ms 18.742 ms 7 188.8.131.52 (184.108.40.206) 36.016 ms 23.138 ms 220.127.116.11 (18.104.22.168) 18.884 ms 8 22.214.171.124 (126.96.36.199) 25.750 ms 188.8.131.52 (184.108.40.206) 25.894 ms 220.127.116.11 (18.104.22.168) 26.818 ms 9 22.214.171.124 (126.96.36.199) 25.593 ms 188.8.131.52 (184.108.40.206) 26.244 ms 220.127.116.11 (18.104.22.168) 26.215 ms 10 22.214.171.124 (126.96.36.199) 25.734 ms 188.8.131.52 (184.108.40.206) 36.192 ms 220.127.116.11 (18.104.22.168) 35.259 ms 11 px-in-f106.1e100.net (22.214.171.124) 26.519 ms 25.346 ms 26.101 ms
at the same time I could reach a dozen other sites.
After rebooting everything is going swimmingly. Any advice on what I can do to diagnose this problem. What other tools can I use to help the diagnosis.
I'm running 1.2.3 release i386, but I had this problem on 2.0 RC 2 but I downgraded to 1.2.3 hoping to get around this problem.
My current setup is
SUPERMICRO MBD-X7SPE-H-O (Intel 82574L) –> Asus rt-n16 running dd-wrt (but had the same problem with other routers) --> 30+ users
I'd love to hear any insight you have.
Are you using sticky connections? if not http://doc.pfsense.org/index.php/Unable_to_Access_Some_Websites and maybe change DNS provider to e.g. opendns.
I don't think I have sticky connections. Correct me if I'm wrong but I would not have that unless I have a multi-wan setup (which I do not).
Thanks for the link. I've changed my DNS to openDNS for now.
As for the 6 possible causes in the article
1. How would I ensure this?
2. The LAN subnet mask is 255.255.250.0 (Status -> interfaces) in pfsense and the same on the asus router. It is 255.255.240 on the WAN if that matters.
3. Where do I set the MTU? Pinging with 1500 bytes was successful
4. Traceroute does not stop upstream - not applicable
5. Not applicable
6. Did this
I'll post back if I continue to have problems.
