678. There is one newer FW rev to upgrade too (on my todo list). I've had this thing for years and started doing this in the past few weeks (seems like its getting worse). Since it goes in & out of slow response, I'm thinking something is using the connection periodically. I'm hoping to learn how to find out how to determine that! Your idea on age-failing is interesting though... Show errors reports nothing (the usual DHCP messages only). "sh int eth0" had some errors for receive (rebooting reset to 0; will see if it increases during the slow responses). I'll check on its warmth (in the mechanical room with my servers on top of switch; room temp is good) & try a different switch port. Thank you for the ideas! -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Justin Krejci Sent: Thursday, July 22, 2010 4:12 AM To: TCLUG Mailing List Subject: Re: [tclug-list] How detect what's using Internet connection? What version of code are you running? Maybe a newer version could help. Check "show errors" and also look at the eth interface stats for various error counters on the cisco. Additionally some models of the 67x (you didn't mention which you have) get very hot on their own so if you have it in an already warm room with minimal air flow it could be overheating and nearing the end of its life. If this seems like the case then try propping it up so the bottom is more accessible to some air flow. You could check the cable from the Cisco, try replacing it with another cable. Is it going to a switch? Try another switch port. Basic things like that can sometimes identify/eliminate during troubleshooting and are super easy to try.

Lately I've had a lot of slowdown with my DSL router. None of the machines appear to be downloading, streaming, etc. (they could be, but didn't look like it to me). For example, at the moment, pinging the router: PING dslrouter (10.0.0.1) 56(84) bytes of data. 64 bytes from dslrouter (10.0.0.1): icmp_seq=1 ttl=64 time=1686 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=2 ttl=64 time=1326 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=3 ttl=64 time=1163 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=4 ttl=64 time=762 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=5 ttl=64 time=992 ms ^C --- dslrouter ping statistics --- 6 packets transmitted, 5 received, 16% packet loss, time 5488ms rtt min/avg/max/mdev = 762.641/1186.396/1686.273/312.092 ms, pipe 2 After I reboot it, it's back to sub-millisecond time. But after a short while, it's back up there. It's really slowing down even casual surfing, and the wife keeps yelling at me about it! :-/ And then sometimes, like now, it is back to normal (but it was slow response for awhile, maybe an hour or more?): PING dslrouter (10.0.0.1) 56(84) bytes of data. 64 bytes from dslrouter (10.0.0.1): icmp_seq=1 ttl=64 time=0.811 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=2 ttl=64 time=0.862 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=3 ttl=64 time=0.873 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=4 ttl=64 time=0.841 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=5 ttl=64 time=0.810 ms 64 bytes from dslrouter (10.0.0.1): icmp_seq=6 ttl=64 time=0.830 ms ^C --- dslrouter ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5225ms rtt min/avg/max/mdev = 0.810/0.837/0.873/0.044 ms How do I detect what is happening at the time of high load? It is a Cisco CBOS DSL router. I've been trying some CBOS show commands and wondering about either Linux or Windows commands/apps to use? _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota tclug-list at mn-linux.org http://mailman.mn-linux.org/mailman/listinfo/tclug-list _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota tclug-list at mn-linux.org http://mailman.mn-linux.org/mailman/listinfo/tclug-list
