发表于：12 Aug 2005 作者： Ken Phillips m0mcw Post: Cheers for your replies, I've just checked up on the Einsteins, and LHC units that got uploaded overnight, and they validated fine, even the ones the machine was working on, as it's mainboard failed, how's that for scientific robustness? On that basis, as much as the science is different, I'll assume until proved otherwise, that the seti@home work is in 'good hands'. Bye all, Ken P. |

发表于：12 Aug 2005 作者： Ken Phillips m0mcw Post: Not me guv, honest! However, I've just experienced the dangerous occurrence of having a thought (ouch), if the validators are so backlogged, it could well be quite some time before I even know if my trusty cpu, and it's bright shiny new mobo, actually co-exist together and crunch properly, although I suppose that my returns to LHC and einstein would give me some idea. I got the machine up and running again, in time to start crunching and returning some einsteins that had got near deadline, some pre-failure LHC's are still in progress, as is a climate prediction unit with only 1 and a bit days on the odometer Does anyone know if seti@home work is being validated at all, or is it just that the backlog is moving, but, it's slowing down all the time, so the number of WU's pending just gets bigger? I haven't a clue myself, as I've not really had my attention on the status page. Cheers, Ken Phillips |

How do I tell boinc to finish what it's got, but get no more?
(消息 150273)
发表于：11 Aug 2005 作者： Ken Phillips m0mcw Post: Set to 0.0 instead and you won't receive no more WU! Won't this 'connect to time' then propagate via updates, to the other science applications as well? Thereby causing all of Dorsai's projects to stop downloading? I can't readily test this, as I don't have 4.19 installed on anything anymore. @Dorsai, If you upgrade to 4.45, then you can just suspend, stop downloads, etc., from the boinc manager, however, I'll understand if you are a bit wary of doing so, purely because of 4.45's quirks.

发表于：11 Aug 2005 作者： Ken Phillips m0mcw Post: At the moment there seems little point in requesting more work, as all this will do is generate more results to add to the ever growing pile. Open Boinc manager, got to the projects tab, highlight Seti@home, on the left pane of the window, you should see a 'no new work' button, click it; job done. Come back soon :) Ken Phillips |

发表于：11 Aug 2005 作者： Ken Phillips m0mcw Post: This might be a bit moot point at the moment, but, I've just replaced the mainboard on one of my hosts to resurrect it, unfortunately, I couldn't get the same model as previously installed, so I had to do a repair install of XP. Anyway less of the twaddle; when the host came back up, before all the relevant updates, etc, it munged 16no03ab.2904.785.354830.237 and 16no03ab.2904.785.354830.53 results, while attempting to download before it wasn't fully ready. [edit] Damn! Found another one 16oc03aa.979.10945.984656.208, I've changed the links to WU names, to save anyone having to click them :-) [/edit] Apologies for holding up anyones validation, not that it really makes much difference at the moment. I'll have to try and wangle a faster cpu now, the new mobo is a lot better. Cheers and beers! Ken Phillips |

Oh My! Another outage!

发表于：11 Aug 2005 作者： Ken Phillips m0mcw Post: yeah, it was Message 150048 that accused me of stealing. Sorry to have to continue this folks, I, like several others am beginning to think 'troll' in connection with the doctor, I also agree as said earlier, that this thread should now be closed and allowed to sink into obscurity, but to continue:- Doctor, I'd like to think that no one has any problems with the number of computers you operate, apart from envy that is. The fact is, that that number is really quite small compared to some other volunteers involved with seti. The problem as I see it, is why you saw fit to need 3 separate user accounts, again, when there are folks on here with many more boxes than you, all on one single account - was this simply because you'd evaluated what sometimes goes on on here, and decided you'd rather have three chances to vote?

If the infrasructure of Boinc is so broken, period!, then why is the infrastructure of Boinc, and it's hosted, but, separate science applications of which seti@home is but one, working so well, in spite of a few glitches? I run 4 projects via Boinc, they are all working, and reporting, sometimes not brilliantly, but, they are working, and science is being carried out. Boinc is not broken, Boinc is working reasonably well, for a work in progress. I repeat, because obviously some folks are having problems with the english language, and understanding certain key concepts, that Seti@home (not boinc) has some issues, and there currently are some signs that the connectivity issues, apparently due to a misconfigured and/or faulty router on the cogent network border, well beyond Seti@homes control, have been addressed. If you are going to throw your expensive toys out of your so well equipped and oh so perfectly configured playpen, then at least get it over with, just do it and go; either that or get your facts right, get it sorted, get over it, and get crunching. There are some folks on here who have been having problems connecting to Seti@home, yes, Seti@home, not Boinc, Seti@home, for longer than you have, some of the affected folks are now able to connect unassisted by proxies, etc, for the first time in weeks, and they should be proud to have been part of the solution, not just whining, threatening and saying 'it's not at my end'. All this misguided Boinc bashing is now seriously doing my head in, period! Ken Phillips |

Seti disabling my computers?
(消息 148626)
发表于：8 Aug 2005 作者： Ken Phillips m0mcw Post: My fastest computer managed to connect to seti this morning (I'm in England) but I'm having difficulty connecting any of my other computers, I know that the schedulers are online because my fast computer can connect to them, but all my other computers just show 'No schedulers responded' every time. Whats going on is it something to do with this figure '100/day'(on my fastest computer) under the 'Maximum daily WU quota per CPU' and all my other computers show stuff like '1/day' and '41/day' I don't even no what 'Maximum daily WU quota per CPU' actully means. Also are SETI or BOINC going to create somekind of system that stops peoples recent avg. credit from going down when SETI has an outage because about 3 weeks ago I had more that 500 RAC!!! Thomas, First of all, it's very improbable that seti is 'disabling your computers', purely because Seti@home is just a science application hosted by Boinc, and Boinc only uses, but doesn't change whatever network (internet) setup you have got. Unfortunately, no one can even begin to help you, unless you can provide some more information, such as; how do all your computers connect to each other and the internet? Dialup? Broadband? Internet connection sharing (ICS)? Router? Network address translation (NAT) , Proxy or 'direct'? Operating system? What numbers (default gateway, dns server, ip address, ........) does typing IPCONFIG at a command prompt give you? Can you browse the internet properly on the affected machines? What other connectivity tests have you done from the affected machines, Ping? Tracert? ...... Since the first of two recent DNS changes, there have been some issues with a lot of folks being unable to connect and/or transfer work, while many more others have had absolutely no trouble at all, Ian (Tigher) has done a hell of a lot of work to try and help track the problem down, and has presented the project devs with what information he has collated. I think it's reasonable to say that somewhere along the data path there is either one or more 'bad' routers, a badly configured firewall, an overloaded server, or even a an arguement between two ISP's (de-peering), but so far I think the jury is out, on what the exact issues are. Several people have managed to get data flowing again by setting Boinc to use a proxy, see this list, thereby bypassing the 'bad' route, If you are going to try this, ensure, that you change (where appropriate) Boincs default of port 80, because, not all proxies use port 80, for instance, purely for the sake of experimentation, one of my hosts is temporarily set to use an http proxy which connects via port 3128, and, so far it's happily communicating with seti@home, Einstein@home, LHC, and climate prediction without any hitches.

Need clarification about Proxies
(消息 148179)
发表于：7 Aug 2005 作者： Ken Phillips m0mcw Post: With the url 128.32.18.173 in the http proxy, I get these error message from the other projects When you are using a proxy, you must make sure that you have also entered the appropriate port number; they don't all use port 80, for instance this computer, I'm on at the moment is using a proxy server on the our lan, 192.168.0.1 port 8080, for caching and monitoring webpages, but, boinc communicates directly. So therefore, if you going to boinc via a proxy you also have to set the correct port address in boinc. The correct port, check this list for examples should be published along with the IP address relevant for your chosen proxy. Hope this helps, and that they have not turned seti off while I've been typing. Ken Phillips |

发表于：4 Aug 2005 作者： Ken Phillips m0mcw Post: A bit off topic, but hopefully not too much A thing I've noticed about all this, is that all the testing going on, is dependant on something that on most soho routers is disabled by default. That something, is that which the designers of the internet said should always happen within a short period of time, otherwise, the internet would be slowed down. That something is ICMP echo, in other words 'ping'. It is actually specified somewhere (I can't remember where, sorry), that any IP host, network appliance, or router, should always respond promptly to a ping. Sadly, that is now seen to be a major security risk, but, I do often wonder just how much time is lost, with millions of legitimate ICMP requests waiting up to 1 minute to fail, that otherwise would provide rapid yes/no type information as to whether there was actually something at the other end of the wire. If I can ping my router, then, I know it's there and working, that the kittens haven't knocked it off the shelf it lives on (or done worse with those very sharp teeth!), and that the house probably isn't on fire. I don't really care if everyone else also knows it's there, I leave that problem for the firewall to look after. Just my 2 pennies worth :) Ken Phillips |

Still cant return or pick up WUs

发表于：4 Aug 2005 作者： Ken Phillips m0mcw Post:
Mike, I understand now, with that setup, however, you should always be able to 'ping' between any of your machines by IP number, without difficulty. Even if your external IP address did change after a power cycle, this basic connectivity should never be lost. However, name resolution for your LAN computers, as opposed to those resulting from internet lookups, is usually done using netbios, controlled by any one computer on your LAN which wins an 'election' to become the 'browse master'; this process, also should not be influenced by a change of external IP, if network (not internet!) browsing is problematic, I've often found the cause to be machines fighting over who gets to be browse master. In the past, one of my simpler solutions, to this browse master issue, is to disable the 'computer browser' or equivalent service on all but one computer on the network, which is the one that is normally runing all the time. Then what happens, is that a more consistant tally can be kept by one you have chosen to be browse master, of which name belongs to which mac address, this problem is especially prevalent on networks with more than one operating system. A much more sophisticated solution would be to run DNS name resolution across your local area network, using your own dedicated DNS, DHCP, which then of course would always know, who was what, where when and how. |

发表于：4 Aug 2005 作者： Ken Phillips m0mcw Post: Bronco sent me his ethereal trace of an update to seti servers. Basically the galileo server stop responding to Bronco's client after it had sent a duplicate ack. Martin This was my first thought too when I saw mention of the duplicate ACK ealier today. Obviously, it shouldn't be happening, and could well be interpreted as an attack, but, is it Bronco's client that is doing the mischief, or his router, and, if the router, is the problem more common amongst users of that particular type of router. I know Ian is valiantly trying to get to the bottom of whether it's a TCP/IP stack, OS, or client problem, so I won't tread on any toes there, but, I dare say that if it was more of a client issue, then surely a lot more people would be affected by it? Ken Phillips [edit] Duh! Of course it's his host, otherwise, etherial, wouldn't show it, because, etherial is monitoring his network card. Now, where did I put that spare brain cell? [/edit] |

发表于：4 Aug 2005 作者： Ken Phillips m0mcw Post: Has anyone been following the repairs? I find NASA's casual attitude about the damage to the shuttle very disturbing. Yeah, just pull out the gap filler and leave the space between the tiles. I have a bad feeling about the return flight. I too have serious worries about the shuttles return flight, especially now I know what they have just done. In lieu of other information, I can only assume that the gap filler was not just 'any old fabric', and it's there for a reason. Might that reason be to stop white-hot gas plasma from touching thin aluminium? In which case, bearing in mind that they have just carried out experimental repairs to isolated tiles in the cargo bay, would the materials used be adequate, for an actual 'just in case' repair? I've just been reading about a few other 'small issues' that the shuttles heatshield is supposed to have, but, this now gap, near the nose cone (very very hot) has me extremely concerned. Best wishes to the crew for a safe trip home, and I hope we are just worrying over nothing. Ken Phillips |

发表于：3 Aug 2005 作者： Ken Phillips m0mcw Post: Having another native language than English (Swiss German in fact), i wonder at the usage of "than" vs. "then" in this board (and others...). Barbarossa Some some silly examples (hopefully correct). I've not seen that usage, then again, perhaps I was not looking properly. Your recent average credit is much bigger than mine. If that box is so much bigger than this box, [i]then[i] why is so easy to carry? I was never very good at the 'science' of what we in britland laughingly call english, it's such a mixture of lots of other languages, that it's just crazy. I only speak it and write it, oblivious of why or how sentences work, I definitely can't explain it. Tally ho Ken Phillips [edit] Damn you Ian! Beat me to it; brilliant examples though, I didn't think of your first one. :) [/edit] |

发表于：2 Aug 2005 作者： Ken Phillips m0mcw Post: OK, I'll give you the answer tomorrow (It's 11 pm local time). I'll try to find a DNS test utility for Windows because DNS servers are on my ISP's net and they probably don't answer outside (I can't believe that 10 out of 11 servers are down) Jean-Marc, Have you approached your ISP regarding this? What is their answer to this problem? I note that your associates, who also use the same ISP, are also having the same problem, is it safe to assume, that they are also up and running via a proxy? I am inclined to agree that the issue is looking to be something other than name resolution, purely because even with accurate lookups, your packets are still not making the trip. I can't imagine that the wanadoo and cogent de-peering from some months ago is the problem, because, one of the purposes of the recent dns switch was to move scheduler traffic off cogent, onto another link. I'm having problems believing that packets are being blocked; unless your ISP is very draconian, why would they block traffic to the new scheduler, it doesn't make sense, but, obviously it's happening, I can only think that a router somewhere along the line has got upset, but, if you can ping the new scheduler (can you?), then even that is a duff idea. I know Paul (The Gas Giant) had a similar problem recently (after the de-peering kaffufle), he also fixed it by using a proxy in boinc, but, he had to keep changing proxies, because each one would 'fail' after a few days. I'm not sure if he ever got it all sorted out. I feel for you, but in all honesty, I'm totally stumped at this point, sorry. If you ask your ISP, can you let us know what they say? Best wishes, Ken Phillips |

发表于：2 Aug 2005 作者： Ken Phillips m0mcw Post: I'm less than please with BOINC. With SETI Classic, I rarely encounter the situation where work isn't available and almost immediately provided for processing. With BOINC it seems that I encounter problems getting work or finding schedulers that will respond. I re-iterate; what work is not available? Server status page as of 13:09 UTC today is now reading 491187 units as ready to send. I personally (to prove a point) have just reduced that number by two, with this host, which produced the following log:- 02/08/2005 14:00:06 44 request_reschedule_cpus: files downloaded 02/08/2005 14:00:06 43 Throughput 103221 bytes/sec 02/08/2005 14:00:06 42 Finished download of 28ap04aa.15206.28576.1034646.30 02/08/2005 14:00:01 41 Started download of 28ap04aa.15206.28576.1034646.30 02/08/2005 14:00:00 40 Scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi succeeded 02/08/2005 13:59:59 39 Requesting 29018 seconds of work, returning 0 results 02/08/2005 13:59:59 38 Sending scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi 02/08/2005 13:49:54 37 Deferring communication with project for 10 minutes and 4 seconds 02/08/2005 13:49:53 36 No work from project 02/08/2005 13:49:53 35 Message from server: Not sending work - last RPC too recent: 20 sec 02/08/2005 13:49:53 34 Scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi succeeded 02/08/2005 13:49:52 33 Requesting 32814 seconds of work, returning 0 results 02/08/2005 13:49:52 32 Sending scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi 02/08/2005 13:49:44 31 Starting result 28ap04aa.15206.28481.661080.26_2 using setiathome version 4.18 02/08/2005 13:49:44 30 request_reschedule_cpus: files downloaded 02/08/2005 13:49:44 29 Throughput 36315 bytes/sec 02/08/2005 13:49:44 28 Finished download of 28ap04aa.15206.28481.661080.26 02/08/2005 13:49:34 27 Started download of 28ap04aa.15206.28481.661080.26 02/08/2005 13:49:33 26 Scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi succeeded 02/08/2005 13:49:32 25 Requesting 43200 seconds of work, returning 0 results 02/08/2005 13:49:32 24 Sending scheduler request to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi 02/08/2005 13:49:31 23 request_reschedule_cpus: project op 02/08/2005 13:36:52 22 Insufficient work; requesting more 02/08/2005 13:26:53 21 request_reschedule_cpus: Resuming activities So what is not working? The only reference to 'no work from project' in the above log, is because my host broke an important rule, it cut the tcp/ip connection, then tried to re-establish it before the mandatory and strictly enforced ten minute time-out period had elapsed. If you think you have a problem (apart from me), then post the logs, and/or the host id, and perhaps it can be sorted out. I'm less than pleased with some thing's, but, because I can't, I leave the rectification to those that can, hopefully learning and adapting as things happen. Sincerely, Ken Phillips |

发表于：2 Aug 2005 作者： Ken Phillips m0mcw Post: Just ran out of work. Well it's time to give the computers a break till Seti decides to make more work available. Losi, According to the server status pages there were 500,958 work units waiting for distribution as of about 10 minutes ago, so the project certainly isn't short of work to hand out. Could you please let us know what messages you are getting, indicating to you that there is no work? If you are not getting any otherwise meaningfull messages, check that you have not inadvertantly clicked the no 'new work' button on the project tab; you will know if you have, because the button will now be 'allow new work'.
