[T]he project is having significant technical problems. The complex collection of servers - some very elderly - the project relies on are suffering intermittent failures: a key component (a router) linking the lab to the outside world is showing signs of impending failure: and the inexorable increase in volunteers' computer power is putting every component under increasing strain.

At 21:00 CDT I tried all the same pings, traceroutes, and nslookups that John did, and they are all up and reachable and show no problems. Using Cox Communications in Omaha, NE. |

Based on pinging, etc. it appears the HE connection problem comes and goes for me. When the problem is here, my messages say "BOINC can't access the Internet". That tells me its time to switch to a proxy, clear my uploads and fill my cache. I can't leave it on proxy, since some of the other projects don't work then. That is more babysitting than I normally do with BOINC, but it keeps me crunching. |

I believe if you get the response that Boinc can't access the internet, the problem is on your end, as I think that is generated after Boinc tries to get to Amazon or Google as a connection test. I only get that if my router or modem goes flaky and needs a reboot. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

We are working with HE to clear up this routing issue. They are being very helpful. We will need to involve parties beyond HE. Here is a little bit of background. Our PAIX router physically talks to HE on one side and to CENIC on the other, whereupon the physical path proceeds through CENIC, then through UCB, then through SSL before finally landing at the router in our closet. All of this even though, logically, we tunnel directly from our PAIX router to our closet router. Both of our routers were donated by Packet Clearing House (PCH). They also helped us initially set them up and physically host our PAIX router in their rack at the PAIX. PCH really came to our rescue way back when we learned that we could not use (or afford to use) the UCB commodity provider. They also helped us migrate from Cogent to HE. Back to he problem... HE guessed that we don't have enough memory in our PAIX router to hold the giant routing table that we need to hold. This is more or less confirmed by looking at the memory stats on that router. One solution (the best) is to add memory, or replace the router if it cannot take more memory. Another, perhaps interim, solution suggested by HE is to have our router utilize a default route rather than maintain a huge routing table. We tried that. Well, at least HE did their part to make it so. And it flat-lined our traffic. Thus our need to involve the other players. I have emailed them all. But everyone is super busy and, in the case of PCH, all effort is donated. Speaking of being super busy.... I apologize for the the lack of communication recently. Both Matt and Bob have been gone for the past month, and Eric for the past week. That leaves one man on deck. So I'm a bit um.. stretched. |

Thanks for the update Jeff. Should we be thinking about a fund drive for more router memory yet? Or should we wait until we see if you might need a new router? Thank HE for us and everyone else involved too. Now, get back to work!!! Only joking. Thanks for all the work you have been doing and for keeping us updated.

Thanks for the info Jeff. Hopefully the router isn't maxed out at 1GB already and just has like 128mb or 256mb in it. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

And thanks from me, too. All of which raises another question. What happened back in June to make the routing table, apparently, outgrow the memory which has served us for the last three years or more? According to http://boinc.netsoft-online.com/e107_plugins/boinc/bp.php?project=19 the numbers of both active users and active hosts - then only ones of interest to a router, surely? - have been declining steadily for the last three months. Even if there was a peak in June, we should have dipped back down below the limit by now. Or have the routing tables themselves grown in size with the preparations for IPv6? |

And thanks from me, too. With the IPv6 stuff starting up in June that is a very good possibility. Maybe just having the router drop IPv6 packets for now could be a solution. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Thanks for the update Jeff, Any chance re-enabling the scheduler at Seti Beta so we can have half a chance of reporting our results there please? Claggy |

Thank you very much Jeff for the informative post. Now perhaps some can understand how involved the problem is. Please do let us know if the router memory is upgradable, and if so, what you need. I am sure we can get together and get it in your hands post haste. Same goes for a different router, if that is what is required to get the problem completely fixed. Just give us the specs on what would be needed for a proper replacement, and most assuredly it shall be a top priority for us. Meow!! "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Not sure if anyone else has tried but I flushed the dns on two of my work machines that had not connected in over a week. Now they have shown that they have communicated with S@H. Did it yesterday on one machine and saw results, and another today. Just throwing this out there if no one else tried it yet. You never know. IAS - Where Space Is Golden! |

Hello there, The only project I'm having trouble with is the Seti@home project. This problem only majorly appeared in the past week. Before I have had sporadic problems but it always worked itself out. My ISP is Cincinnati Bell. I live in Cincinnati, Ohio All pings to the 4 ip addresses failed with 0 results (100% failure) Unsure what traceroute or nslookup is. Hope this helps. |
