My pings from Australia get NO response! :(

I have a machine which has spent almost a week trying to connect. Again :(

So... If you have connected in recent days, "kwitchawinjin!" [Quit your winging!]

I have about 2000 run unit to upload and zero work in one host.
Also in the zero job host I see that is "not requesting new tasks" (!!)

using pathping I see the same situation of others (100% lost in some hop) so I don't add my data.
Instead I think that this trace (from switzerland to Berleley) can be interesting

The coresite.com switch must be set to silent, it doesn't respond to a straight ping test either.

Maybe the traffic for SAH is clogging the upstream switching as well ?

Just one idea.
Recently I have read about a big hacker attack and may be a lot defense policies have been implemented in some hops.
Maybe some of them are disturbing seti traffic.

I was able to Update this morning here, but still have ~50 uploads pending in the queue. Some uploads must be trickling through from time to time. Curiously, no new work was requested! I don't really understand that.

I'm still seeing some losses on the west coast (only).

This is the longest time that uploads/updates have continuously failed/backed-off for this project I have ever seen. The problem did start before the A/C outage. (Just an observation.)

Many thanks, and good luck, to those in charge, dealing with the frustrations of modern computers.

Boinc won't ask for work from a project, if the the number of uploads for that project exceeds twice the number of CPU cores,
so until you're down to a handfull of uploads, you'll get no downloads from Seti,
But you can still get work from other projects.

It seems like a provider peering issue. Here's my trace route from Palisades Park, NJ on TimeWarner Roadrunner. The trace takes a dump midway on the rr.com network and it gets worse on the Hurrican Electric he.net network.

100% packet loss from me in Sweden.

Looking at the cricket graphs, the bandwidth utilization is much lower than normal. I would say that it's a router or switch issue, either on SETI location, or somewhere in between the users and berkeley.

Sten-Arne

Did you see my observations with Wireshark and a fortuitous download in Panic mode...? I have no prior experience with Wireshark (willing to learn if anyone here can guide me), and it's fearsomely powerful (i.e. complicated), but what I saw led me to the opposite conclusion.

Things just doesn't get through, and it's not because of maxed out bandwidth...

Fully agree with that. But the packets I was wiresharking (from the UK) seemed to have a reasonable chance of reaching Berkeley, getting through all the routers and switches, and starting to communicate with Bruno. It's the RST+ACK from Bruno that seems to be causing the problem (for uploads: I haven't tried probing Anakin - scheduler - yet).

I'm in no hurry. If my PC's runs out of WU's to crunch, I'll just shut them down and go out and play in the snow :-)


I agree. I still have a couple days worth of VLARs for the CPU to chew on.

BTW: Are you losing 100% just in Calif or before?

@Richard Yes, we could use some expertise I think.
