This again sounds like a packet size issue.

Have you tried the ping with the various sizes?


Up to packet size 1440 included, everything works fine respons times up to 175ms.
At size 1472 and higer it times out.

OK, try setting the MTU value on your router to 1440 to see what happens.

Well i have been through almost all MTU and RWIN settings but still no luck.
However i realised that, after i upgraded boinc on this PC from 5.4.11 to 5.8.8, i had not seen it download a new WU yet. It did finish, upload and report the ones present.
So i have just removed boinc 5.8 and re-installed version 5.4.11 and lo and behold 2 WUs downloaded without any problems and it's happily crunching them...

So something must have changed in the download routines between 5.4 and 5.8 wich my win98 environmentcan not cope with. Any ideas??

Actually, it is more likely that you have a large cache, and 5.8.11 is correctly determining that you are going to have trouble meeting deadlines before your next promissed connection. (only one setting available, and it is used to describe how long the network will be off between user initiated connections.)

No this has nothing to do with the cache. As you can see in my original post BOINC is trying to download a WU but the actual transfer does not succeed.

I had a look in my firewall log and it showed time-outs on a cogent server??? I don't have a hosts file set-up and running tracert on setiboincdata does not route via cogent.
Is there a config file within boinc holding route info?

OK, if you are still going through Cogent, there is someplace a cached version of the DNS entry for S@H that is woefully out of date as S@H has moved to a new provider.

Actually, I think it was 5.8.8 he was trying with, and FWIW, my 9x'ers were not too happy with that version.

Might want to give 5.8.15 a try, which has run without any problems of this sort.

Hi,

I recently had the same problem "SETI@home|[file_xfer] Temporarily failed download of setiathome_5.15_windows_intelx86.exe: system connect" and stuff like that..:) It seems like SETI data server was altered/changed. Previous connection rules for BOINC application to setiathome.SSL.berkeley.edu (128.32.18.152, 208.68.240.11) and boinc2.ssl.berkeley.edu (66.28.250.124, 208.68.204.13) is no longer sufficient. I had to add a rule for my firewall for BOINC.EXE application to allow outbound connections to setiboincdata.ssl.berkeley.edu (208.68.240.16). After creating this everything went smoothly..

Cheers,

josuah08

Berkeley changed ISPs about a month ago. This of course generated new IP addresses.
