Message 784343 - Posted: 19 Jul 2008, 14:58:05 UTC

Since a few days I cannot upload or download anything with boinc/setiathome anymore.

I'm using boinc client version 5.10.45 for i586-pc- linux-gnu and setiathome_enhanced version 5.27 on Mandriva Linux Cooker.

As Cooker changes daily I tried to find any programme or library change that might have been the cause, but going back to the older version before I stopped being able to connect made no difference, so that does not appear to be the cause.

I reinstalled boinc from scratch: no difference.

When I try to upload any of the finished tasks I get above error; when I tried to update, I get: "[error] Couldn't start download of scheduler list: http error"

It would appear that the above error has to do something with he way curl connects with the aide of the file "ca-bundle.crt" in my BOINC directory, but there appears nothing wrong with that. I also tried with the same file from /etc/pki/certs, but that made no difference either.

Now I am at loss what to try and would appreciate any assistance to connect again. Thanks i.a.

Looks like a library problem. Which BOINC client do you use ?
Have you tried the offical BOINC client from boinc.berkeley.edu ? - So far I know is it liked staticly, so you should not have this library problems...

I have the official BOINC client from boinc.berkeley.edu: latest version 5.10.45 for i586-pc-linux-gnu, so how can I fix it?

Could you please post the messages from a connection attempt when this errror happens.
Also the output from "ldd boinc_client" would be helpfull.
Do you use an proxy or firewall ?

See above in my first post:

and
[error] Couldn't start download of scheduler list: http error

I would see the messages in the context what exactly happening !

Do you have the boinc or boincclient binary in your BOINc directory. - I need the ldd from the BOINC client binary.

Message 785465 - Posted: 22 Jul 2008, 20:49:36 UTC - in response to Message 784750.

One more bit of information: counting backwards I found that the moment my seti connection to the seti server stopped working was during last week's server outage for maintenance on Tuesday evening: early evening I uploaded my last few tasks that I could get through, these same are still "Ready to report".

I dunno if it has any bearing, but chances are.

I'm working on my last task I downloaded before the error appeared and the oldest tasks are nearly overdue.

So I do hope somebody can give me some clues to fix this. Thanks i.a. !

Message 787440 - Posted: 26 Jul 2008, 10:08:17 UTC - in response to Message 786870.

I found the cause of the problem: /etc/nsswitch.conf was not readable to the user. Fixed and working again.

Thanks for your time.
