	Have any of the path-pingers retried their packet loss counters a) While SETI is running at maximum throughput b) Tomorrow, while things are quiet during mainteance Be good to get some 'normal case' reports over the same paths as the existing tests, to predict whether the technique will be any use during the next outage.

	Yes, I say again, WELL DONE!!! Bet we are really hammering the servers, hope we don't break anything else! :-) Yes, I agree. I still have 33 WUs, to upload, on my Windoze box. I'm hoping they can get here and get reported before all the "hammering" does indeed break something. ;) Keep on BOINCing...! :) ____________ CMDR Siran d'Vel'nahr XO USS Vre'kasht NCC-33187 Siran's website: [ ONLINE! ]

I wrote and scheduled a script that has been tracking pathping stats every hour since 2010-02-20 16:00 UTC. I may let it run through 2010-03-09 to get a feel for "normal". ____________

	Interesting. WHile you lot were frozen out I was getting downloads on cue as WUs finished. Just the upload and reporting were a problem. Not now though, all gone :D

	Have any of the path-pingers retried their packet loss counters a) While SETI is running at maximum throughput OK, from Albuquerque, NM, during peak about four hours after the Cricket graphs rose to 90+ Mbits/sec 16/ 100 = 16% \| 12 107ms 18/ 100 = 18% 2/ 100 = 2% 208.68.243.254 0/ 100 = 0% \| 13 107ms 16/ 100 = 16% 0/ 100 = 0% setiboincdata.ssl.berkeley.edu [208.68.240.16] looks somewhat higher on this snapshot than during the outage. ____________

	I have two 'zones' running SETI, at home and office My office has coped pretty well during this 'outage' and has pretty much been fully up to date UL/DL's, none pending even when I came to work monday. However my home system (PC better than in the office), which can run SETI (CUDA) still has 60 or more results stuck in the final phase of reporting - i.e. upload completed just not reported and does not appear to have since the outage. That's all of the WU's with no more coming in. So the routes peoples systems have to take to reach SETI may be the issue after all? At least the other projects are 100% ok, QMC, Rosetta, Einstein and Milkyway. :) ____________

At least the other projects are 100% ok, QMC, Rosetta, Einstein and Milkyway. :) No - I think you'll find that your home machine hasn't even tested the network to SETI recently. This sounds like one of the recent features in BOINC has kicked in: if network congestion were really to have been the problem, there would be no point in adding to that congestion by continually retrying. The trouble is, no-one has thought of a way of getting the message "It's OK, the congested has cleared, you can retry now" through to a client which isn't retrying.... Just for your own information, have a look at the Messages tab in BOINC Manager to see if the home machine has even tried recently: and then go to the Projects tab, select SETI@home, and click the Properties button. I expect you'll see some high values for backoff times. Just click 'Update' once. That'll start BOINC communicating again: now that the backlog has cleared, your finished tasks should be reported at the first attempt, and you should get new work within a few minutes - there's not much available at the moment, but new work is being created continuously.

Measuring again well within the first hour after the cricket graph dropped well down from the long high stable value: 0/ 100 = 0% \| 12 54ms 0/ 100 = 0% 0/ 100 = 0% 208.68.243.254 1/ 100 = 1% \| 13 53ms 1/ 100 = 1% 0/ 100 = 0% setiboincdata.ssl.berkeley.edu [208.68.240.16] so it may be that in some sense this signature is one of overload--but not of the primary problem of recent times. ____________

	The Cricket graph shows that Sunday night, 2010-02-21 from 22:00 to 22:30 PST there was very little activity on the network. The Berkeley router was still dropping packets at about 6%. Today, 2010-02-23 at 5:20 PST Cricket shows activity at 30+ yet there was 0% packet loss. Running pathping on a business in the same area who also happens to be a Hurricane Electric customer yields 0% packet loss. Do we have a faulty router at Berkeley? ____________

	Did run 2 pathpings, one from my laptop, which showed no difference. Also one from X64 host, same results, in packet loss. Although this host asked, after uploading results, 1 task and received 15. This host, contacts SETI, atleast a hundred times a day and this is my only CUDA-host. I'll watch, if this CUDA-host, does contact more times compaired to the non-CUDA-host's. ____________ Knight Who Says Ni N!, OUT numbered.................

Either that, or the person who administers one router has pings limited, and the person who administers the other does not. ____________

	Hey, Guess what... In spite of a lot of people wasting their time complaining about uploads/ downloads not working, inefficiency of an under-funded system, etc ad finitum the SETI crew sorted the problem! how many moaners contributed to this effort? How many SETI staff complained? If you have time to criticise others then you have too much time on your hands, use that energy to improve your own life and satisfaction. I do not mean to offend, just state the obvious truth. Perhaps, in future, people will be a bit more patient in this ever more complex world....... END OF RANT! ____________

	Rather than complain out there get up off of a few dollars, euros, pounds or whatever and help these folks out who day in and day out bust their chops for us. We can't be there to help them but our money can. So let's get some green stars up there and show Eric and the others that we are truly in there with them. I can think of little else that could be more help to them. S.E.T.I cannot live by computer power alone...it must have financial help as well. ____________

I also praise you, Ned, you only offer support and advice within the community (without getting involved in bickering about connection problems, funding, etc). Phil H. Thanks for the nice compliment. No matter how much bickering there is, we have to live with what's possible. Short staff, not much funding for new stuff, and the connection is what it is. So, BOINC is designed to tolerate problems -- and where possible, mitigate them. ... and for the most part, it works well. If you can sit back and watch when you're sure it's doing the wrong thing, you might even see that it works well. While we don't see Matt, or Eric, or Jeff saying "we're working on it" at 11:00pm on a Saturday, we can often tell that something is being done. ____________
