Over and over. Is it me or Einstein@Home?

request failed-return value 500

Hello, Brad,

Welcome to Einstein. The problem you are suffering has been coming up fairly often on the Boinc messageboards recently, but up until now Einstein has been spared the woes. The first thing you should do is close Boinc for a while, let things settle down, and then re-open to see it contacts the server successfully, because this 500 error seems to be a server or internet error. If Boinc is still unable to establish server contact, we'll have to go just a bit deeper. The suggested fix, as far as I've been reading, is to modify the MTU value in your TCP/IP settings, and unless you are comfortable drilling down into your registry settings, I think it would be best to try and sit this one out. There are utlilities that will handle the "heavy lifting" for you, but no names spring to mind right away. I see that your rigs are running WinXP Home sp2. Could you please tell us how you are connected to the internet - dialup, DSL, ...? My guess is that you are on a DSL connection, but I don't want to go on guesswork here.

Regards,

Michael

Brad,

I've done a little digging and come up with a utility to adjust the MTU setting. The name is System Mechanic, I've tried it a few times, and it's available as shareware on a trial basis. You can download it from PCWorld here. this will relieve you of the hassle and risk of manually editing the Windows registry. If you'd like to go this route, let me know when you have it installed, and I'll walk you through it.

Michael-think I played with that one once- I'm a novice who likes to learn by doing (and re-formatting!!). MTU is maximum transmission unit? Anyway if its fairly staightforward I'm not really afraid of regedit.

Ok, Brad, here we go. Be

Ok, Brad, here we go. Be forewarned, this will take some trial-and-error, and ALWAYS make a backup (export the registry and save) before tinkering in there. One false move and you may wind up re-installing Windows, servicepacks, endless updates, drivers, yada yada. A botched registry job is just about the second-worst calamity, behind a botched BIOS update.

HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Tcpip/Parameters/Interfaces. Open each of the parenthesized folders in turn and look for MTU in the "Name" column. In the "data" column there will be a value, expressed in binary, with a decimal value in parentheses. Probably this decimal value is set to 1500. Right-click on the MTU in the Name column, select "Modify", not modify binary data. Where it says "Base", tick the "Decimal", and then in the space to the left, enter the new value, and OK.. Lowering this value seems to enable the balky connection. Here's where the trial-and-error comes in. The MTU value should be lowered in steps of 5% to 10%, and after each adjustment, start Boinc again, repeat as necessary, though I wouldn't go much lower than 500. You might want to bookmark the registry key, as this could get numbingly repetitious. I am not sure whether reboot is necessary each time for settings to take effect.

Are you SURE you wouldn't rather wait this one out? :-)

(edit) If your registry has a second ControlSet (002), you may have to duplicate the value there, but I'd adjust only the (001) first.

Michael-well- dealing with

Michael-well- dealing with binary might be a challenge (10 kinds of people in the world- those who know binary, and those who don't). At any rate it's bedtime here in Hawaii. Will let BOINC rest overnight and see what happens. System Mechanic might look good at that point. Will report here how it goes.

Thanks much for your kind attention.

Brad

Brad, I've edited the instructions, so give them a second look. You can do it all in decimal.

Brad, try taking it down to 456 (I've read that they are having some success with that setting), and if there is more than one ControlSet folder, make the change there, as well.

If you find no success after that, I'd restore the values to whatever they originally were, and chalk it up to server problems exacerbated by widespread internet problems, and I don't like saying this, but just wait it out. the problem is being discussed by the developers, it's a priority, and if there is any remedy to be found on the server- or client-side software, it will be implemented ASAP.

(edit) What knowledge I have of this problem is solely from reading much of the discussion on the Boinc boards and what there is to be found in my dev-list emails, so I'd like to invite Jord or anyone to step in here with something more definative, PLEASE!

Michael- will do, but one question-will these changes have any effect on my other online activities? I rarely do any significant uploads, but download rather promiscuously.
