g'day ... I've recently started having an issue on my desktop that I've been kinda hounding the cable provider about, but, from their end, they see absolutely no issues ... so I figured I'd see if there was maybe something happening within the OS itself ... Here is the issue ... periodically, for 60-120 secs, my SSH connections to servers in both Panama, Central America and Toronto, Canada, will hang ... seems to be totally random ... Web *appears* to work during that time, and I have Azureas running and *it* appears to keep running during that time ... I suspect that my IMAP connections (fetchmail) are also being affected, since I get the original "timeout" emails from fetchmail ... I am running: FreeBSD 6.1-RC #21: Sun Apr 30 20:56:36 ADT 2006 On: CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2394.01-MHz 686-class CPU) And my Internet connection is running on: fxp0: <Intel 82550 Pro/100 Ethernet> As I've mentioned above, I have been bugging my cable company about this, but they can find no reasons on their ends to account for this ... I have a business account, so I'm not dealing with "Residential QoS" issues on this one ... Is there *anything* on the OS side of things that I should be looking at that I may be overlooking? Any known issues with the fxp driver that might be causing this? I've always found it to be a more then stable driver, but things can happen ... Also, please note that I don't have a router between the 'Net and I ... my desktop is our network router, so the fxp device is directly connected ... Thoughts? Thanks ... ---- Marc G.

If the problems are frequent enough, maybe you could try running tcpdump on the network at both ends. That might give you a better idea of what is going wrong. -- Peter Jeremy

Older Azureas clients have caused me many headaches on my home network. I understand your network is much more robust than what I am running on. However, Azureas runnign on MS Windows XP clients caused network problems which affected my FreeBSD installation. I never did trace the cause except that when Azureas went away so did the problems. The newest Azureas client seems to play much nicer though and I haven't been experienceing any network issues. The symptoms you describe sound very similar in general to the ones everyone on my network experienced, albeit with different applications in play. Best Regards, Duane Whitty -- duane@greenmeadow.ca

Do you have any firewall rules in place that could be responsible? The suggestion of a tcpdump at both ends is a good one. -Jonathan -- Jonathan Noack | noackjr@alumni.rice.edu | OpenPGP: 0x991D8195 -------------- next part -------------- A non-text attachment was scrubbed...
