last i heard you had to request an account on the mailing list to be able to joinYou could join the Boinc Alpha mailing listHey thanks. I am on that mailing list already but I am not able to participate in the testing. Perhaps Dr A will open it up for me LOL! @Lee I didn't know I needed to request. Perhaps I will. Error 500 - I know 500 to be a boinc message not a HTTP protocol error message. Its just a general "umbrella" the devs used to hide loads of stuff. It was not that always though. All errors from the fastcgi server were reported accurately to apache which then generalised them into a 500 error. Sad but true. Then came libcurl which made a situation that could handled almost impossible as it hid or screwed up messages even further which is where I took a long rest from it as I had chased it since Feb 05 through to Dec 06. As for the wiki i have done some in there under network trouble shooting. If you want to re-work that (if its still there) then fine by me. |

As for the wiki i have done some in there under network trouble shooting. If you want to re-work that (if its still there) then fine by me.sorry, i didn't realise you had an account i don't mean to re-write other's work, i only mean to expand on the existing info, for those that are more interested in the underworkings of it all (and those that want to use Ethereal) in that case if you'd prefer to write an article on it, please feel free, i'll leave you to it, the reason i requested an account is because i've got some spare time these days and thought i could help improve the rather basic networking background/info in there, but if you've got it handled then no worries Want to search the BOINC Wiki, BOINCstats, or various BOINC forums from within firefox?

The same basic pattern is used by many internet protocols, but not all. The first digit is the severity of the error, "2" is no error, "3" isn't really an error but it's not exactly "ok" either (things like redirecting in HTTP), "4" is a temporary error (like out of disk space) and "5" is a permanent error. The second digit tells what returned the error, and is a little more open to interpretation. For example "42x" is generally a temporary error with the server (like out of disk space) while "55x" is a permanent mail server error. In theory, the third digit is standardized by server type, but it's really all over the place. "500" is just a general purpose "something was bad" message. |

No no please. You misunderstand me. Please do write or re-write as you wish. I have less and less time. Since I retired I have more work than ever....odd but true! No time hardly in the next 2/3 months to speak of. So by all means carry on. As for material I have traces but I promised those who passed them to me confidentiality so I am unable to pass them to you. Getting info is very hard as you cannot see the other end of the transaction. Soemtimes the 500 will come from a time out in the client...sometimes from the apache server...sometimes from fastcgi...sometimes well who knows. There are scripts that have been added at my request by the devs but seti has yet to implement them They show transactions but they are huge as you can imagine. Good luck! |

@Nedd. Yes I do appreciate that. The problem was that the devs started to use "500" as a boinc fail which got mixed up with 500 from HTTP. Also Apache just used it whenever the fastcgi server reported an error. Fastcgi actually reported good errors that were accurate. I know this because ucb gave me some logs to look at and I could see decent error numbers being converted into a bland 500. That's why it was so hard to track. After the Apache and fastcgi upgrade though it all got very much better....until libcurl....then it got much worse but differently. In the end Dr A said dump the 500 generic message and put in proper ones. That's where we are right now. But I lack the time to go on with it right now. |

Please do write or re-write as you wish. I have less and less time.very kind of you :) the network troubleshooting article is still there, and is actually rather good, starting with the basics up to using ethereal, all i've done with it is add the suggestion of using capture filters to only capture web traffic rather than everything to have a smaller file to email As for material I have traces but I promised those who passed them to me confidentiality so I am unable to pass them to you.understandable, not a problem Getting info is very hard as you cannot see the other end of the transaction.so basically someone from berkeley needs to spend a day or so looking into this, because clearly something isn't quite right There are scripts that have been added at my request by the devs but seti has yet to implement them They show transactions but they are huge as you can imagine.indeed, and hopefully they'll improve the situation (or at least easier to troubleshoot) berkeley seem to be behind with most things, einstein have made their scheduler logs available online before SETI, yet SETI started the idea lol and they've served their purpose already, one user caught the scheduler sending the same result to multiple hosts, not just the same WU!

berkeley seem to be behind with most things, einstein have made their scheduler logs available online before SETI, yet SETI started the idea lol Yes Bruce Allen did them for me and Matt L has promised to implement them. But they have been short of time. When they do I might re-join the chase but without material from the server end its too hard. Actually its impossible. Glad they work well at Einstein! |

oh yes, Bruce is very helpful, the only thing Einstein is lacking is good web code, it's a mess at present, things where they're not ment to be etc.berkeley seem to be behind with most things, einstein have made their scheduler logs available online before SETI, yet SETI started the idea lolYes Bruce Allen did them for me and Matt L has promised to implement them. Glad they work well at Einstein! but saying that, Bruce seems willing to improve, i've been working with him to improve the RSS feed (so it's valid and cachable) without material from the server end its too hard. Actually its impossible.indeed, i'm glad that someone is trying to tackle the issue, i imagine it's a mamoth task considering the amount of data you have to sift through Want to search the BOINC Wiki, BOINCstats, or various BOINC forums from within firefox?

indeed i am from the UK, Jersey actually (in the Channel Islands/Isles), so Great Britain actually lolthe RSS feed (so it's valid and cachable)Lee. When you say cachable what do you mean? I just did my team's web site rss feed and never thought/knew about cachable. Can you explain? http://www.boincuk.com/boincukrss.xml if you want to see it. You are UK then? the basic idea of caching is so that a user agent (browser, feed reader, or anything that requests web content) can store a local copy of the content (based on parameters specified by the server) or rather, to prevent/avoid un-needed redownloading of content when it hasn't changed any content can be cachable, you've just got to send the correct headers as this will probably be a long discussion (also considering that i don't know your level of knowledge/experience), it would be best to start a new thread. Just post a link here and i'll follow :) Want to search the BOINC Wiki, BOINCstats, or various BOINC forums from within firefox? Try the BOINC related Firefox Search Engines |

I think you are talking about ttl? If not lets have the thread.if you mean TTL in relation to the IP protocol, then no some caching mechanisms use a timeout value, but it's a completely different thing to TTL (also used for DNS, but again different) I think we need a new thread rather than cluttering up this one with off-topic posts :) UK is UK of GB and NI. If Jersey is GB then you must be UK. ?well, i could be wrong, but my understanding of our overly complicated system is that the UK is england, N-ireland, wales and scotland, but GB is the UK as well as all the little islands around it Want to search the BOINC Wiki, BOINCstats, or various BOINC forums from within firefox?

If Jersey is GB then you must be UK. ?well, i could be wrong, but my understanding of our overly complicated system is that the UK is england, N-ireland, wales and scotland, but GB is the UK as well as all the little islands around it Strictly speaking "Great Britain" usually refers to the large island that comprises the bulk of England, Wales, and Scotland (as distinct from "Little Britain", the French peninsula of Brittany). Anglesey, the Isle of Wight, the Hebrides, and so on are often included, in the political sense of the term rather than the geographical. The Channel Islands and the Isle of Man belong to the British Crown but are not part of the UK. |
