Im just thought I would summarise a few threads from the problem boards. Since Feb 14th a number of French, Dutch and Belgian BOINCERS have have had huge connection problems to UC Berkeley for SETI. There appears to be a routing issue somewhere in USA and probably within Cogentco.com network. For those interested there are trace routes and the like on the problem pages. I can provide more info if folk need to know. I have emailed cogentco.com and David Anderson (not sure where to bring these matters to Berkeley technical people - tell me if you know please). The problem manifests itself as a failure to connect to a scheduler and deferred comms. It never connects after that and some folk have waited over a month to contact a scheduler. Thought you might all want to know especially as new users switching from classic to BOINC now might get a bit disenchanted. All is known to be Ok so far in Sweden and UK so far. |

I'll put my post from over @Help Desk here as well: I just read this over at the Folding fora: Professor Pande, It seems Cogent, Stanford's main ISP for the commercial internet, and France Telecom are no longer on speaking terms. If you'd like to post this to your forum site, perhaps some of your French users could lean on France Telecom to re-peer with Cogent. They're much more likely to listen to their own customers than to us at Stanford. It's also possible that this will work itself out over the weekend. I'll keep you posted if anything changes. Thanks, ITSS As Cogent is also the main provider here @Berkeley, it could be the same problem. P.S.: I hope the thread is readable for non-FAH participants ;) Gruesse vom Saenger For questions about Boinc look in the BOINC-Wiki |

Since yesterday i want to join scheduler for send WU from my 4 PC but it's always defering because "not scheduler responded at ..." I have many Wu waiting. I have update on one of the 4 PC with boinc in 4.25 then 4.30 but nothing better. I have change URL in the xml files for the scheduler : http://setiathome.berkeley.edu/ or http://setiboincdata.ssl.berkeley.edu/sah_cgi/cgi or http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi and now i don't now what is the good !!!

From a DOS box/command prompt type tracert setiboinc.ssl.berkeley.edu . If that last line of the the route is the IP address at Berkeley 66.28.250.125 then you are successfully reaching the server. If your tracert times out and does not give you this IP then my guess is that you are affected. |

Pour les francophones qui rencontrent des problèmes d'envoi de leur WU (tout type de projet BOINC) il s'agit en fait d'un problème chez Wanadoo et les filiales de FT (France Telecom) dont les IP sont bloquées par un intermédiaire US du nom de "Cogent", pourquoi ça l'histoire ne le dit pas.

It seems that relationships between FTelecom and Cogent are not peaceful. According FTelecom, Cogent infringes Peering's policy rules well known from all net's main operators. Consequently FTelecom shuts down Peering's mechanisms with Cogent. By return, Cogent accuses FTelecom and, since Apr,14th, blocks in a 'hole' all IP traffic issued for/from FTelecom specific adresses subsets, breaking links between their captive clients and FTelecom net's users. Other french IP access providers, as Free for instance, are not affected. "il semble que les relations entre France Télécom et Cogent ne soient pas au beau fixe et ce problème n'est peut-être pas qu'un simple désagrément technique : France Telecom a coupé le peering avec Cogent car celui-ci ne respectait pas 2 critères de la politique de peering de France Telecom, qui est officielle et publiée. Sur un réseau classique, une autre route vers les serveurs de folding@home aurait pu être trouvée, mais dans le cas de Cogent, cela n'a pas pu se faire. Certaines sources indiquent que, suite à cette décision de France Telecom de ne plus s'interconnecter directement avec Cogent, ce dernier aurait complètement bloqué les visites provenant d'adresses IP appartenant à des utilisateurs de France Telecom ! Et en effet, selon France Telecom : "Par mesure de rétorsion, Cogent a établi un puits de trafic pour les adresses France Telecom, coupant les routes entre leurs clients monohomés et ceux de France Telecom. Cette mesure est en rupture avec les règles communément admises dans le communauté internet. France Telecom ne peut être responsable en face de ses clients des conséquences de l'action prise par Cogent qui en porte seul la responsabilité". Du coté de Cogent, on accuse France Telecom."

I was doing a little bit of reading on the NANOG mailing list archive, and it confirms some things elsewhere on this thread. The thread starts here. Some background: The term "internet" is a contraction from "inter-network" -- a set of protocols designed to tie two or more networks together. At the highest levels (i.e. largest providers) networks "peer" -- they connect to each other so that traffic from their customers can reach the other network quickly. ... because, ultimately, whenever someone makes more internet connectivity, the connections they sell become more valuable, and they can sell more. OpenTransit (France Telecom) has dropped all peering connections with Cogent. So, anyone who connects through OpenTransit to get to Berkeley is having trouble, and if you are connected to another provider in one of the affected countries, you'll have no problems. |

Hum... Actually, (and as far as I know) the reason why wanadoo users cannot connect to Berkeley's servers any more is that Cogent has blacklisted wanadoo ip addresses. The route via vario/sprint is operational, as shown in the tracert of tigher, and according to the principle of internet itself. |

I think at this level, "blacklist" is the wrong term. You can stop peering without blacklisting -- and the route through verio/sprint may not be symmetrical. It is worth reading the thread on NANOG. I don't know who stopped peering with whom, but I tend to think that someone who reads NANOG knows what really happened. |

The result is that we are taken hostage by our respective operators and that's not good for the project. As a wanadoo user, I'm going to send a mail to France Telecom support. Unfortunately, I'm not sure to have a worthwhile answer in return... |
