Now that CPDN is on-line and providing workunits, I'm receiving "Unable to verify <file> using certificates" and "checksum or signature" errors for workunit files during the download process. The CPDN task aborts with "Download failed". The relevant log entries are below.

Is this an issue on CPDN's end or do I need to reload/reinstate certificate keys locally?

I'll ask, but it's night there now.

PS
Your 3570K machines (1 or 2?) are having problems with a missing file, and crashing everything.
Please check the stderr messages.

I wonder if the certificate is for the old URL...

Hi,

Your post suggests that the executable files have the wrong signature.
We have had a look, and we don't think anything has changed at our end (well, as regards the file download mechanism anyway :-) ).


I have checked, and I can see that we are indeed supplying the same executable files that we always were, and we have certainly not changed our database records of the signatures of these files.

That suggests that the problem is with your client_state.xml file, that your BOINC client uses to check that it has donwnloaded the correct file.

If you could post the snippets of the appropriate <file> segments of the client_state.xml, then we could offer more advice.

You indicated my 3570k is crashing everything and I should look in stderr.

1) What application is 'crashing'? On the CPDN end or on my end?
2) Where is the 'stderr' for cpdn?

Thanks for the help.

- John -

The problem is at your end.

1) Click on your name to the left of your post. This takes you to your Account page.
2) Towards the bottom is Computers. Click on View. This gives you a page listing your computers.
3) Click on Tasks for the computer in question. This takes you to the first page of the list of models for that computer.
4) Select a model. (First column.)
5) Part way down is the error list, closed to make it more compact. Click on the +.

Not sure of the cause(s).

And when I looked at your post in the middle of the night, I thought that it had run more models than it shows now. :(

Thanks for the followup and the concise instructions.

I reviewed the stderr for each task and the results are below.

Task 15794676: Missing libstdc++.so.6 library; libstdc++5:i386 (1:3.3.6-25ubuntu4) and libstdc++6:i386 (4.7.3-1ubuntu1) installed July 26.
Task 15920149: No stderr; CPDN assumes task still in progress.
Task 15927272: Couldn't get input files. Most likely due to download/certificate verification errors as reported earlier.
Task 15928942: No stderr; CPDN assumes task still in progress.
Task 15933156: Couldn't get input files. Most likely due to download/certificate verification errors as reported earlier. Task aborted by user.

The certificate verify and checksum/signature errors reported in msg 46820 (above) are the current issues to be resolved that should allow me to process workunits successfully.

Thanks again for your help.
