Show errors still doesn't have anything for errors, but stats eth0 has: # of Rx Dma Overrun Errors: 744 Stats wan0 has: # of CRC errors: 184 Stats wan0-0 has: # of packets Rx errors: 221 Is the DMA overrun a normal thing or hinting at a problem? I've been googling for info on it but haven't found anything definitive (lots of people had problems, various other things, but I didn't find an answer if it is something to resolve or not). I've also been running iftop and also discovered ifstatus. They only show the net traffic from the server it's running on (of course - all plugged into a switch, so they are isolated). To see what traffic levels are with each device, does it require a managed switch or is there another way? I have a Netgear JGS524, which is unmanaged. On a family shared Windows machine, between the wife's ton of FF browser tabs open and refreshing (timing out too) and son's Steam service for Call of Duty Modern Warfare 2, that PC had a lot of traffic. Just had the slow response again, and stopping both caused the traffic load to drop. Can't believe that "little" traffic would cause: PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. 64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=2281 ms 64 bytes from 10.0.0.1: icmp_seq=2 ttl=64 time=2446 ms 64 bytes from 10.0.0.1: icmp_seq=3 ttl=64 time=3542 ms 64 bytes from 10.0.0.1: icmp_seq=4 ttl=64 time=3848 ms ^C --- 10.0.0.1 ping statistics --- 8 packets transmitted, 4 received, 50% packet loss, time 7631ms rtt min/avg/max/mdev = 2281.878/3029.851/3848.356/676.891 ms, pipe 4 And with them stopped: PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. 64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=0.853 ms 64 bytes from 10.0.0.1: icmp_seq=2 ttl=64 time=0.825 ms 64 bytes from 10.0.0.1: icmp_seq=3 ttl=64 time=0.842 ms 64 bytes from 10.0.0.1: icmp_seq=4 ttl=64 time=0.843 ms 64 bytes from 10.0.0.1: icmp_seq=5 ttl=64 time=0.847 ms ^C --- 10.0.0.1 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4448ms rtt min/avg/max/mdev = 0.825/0.842/0.853/0.009 ms Might have found a couple of the causes (or all!?). -----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
