Code: Select all

171.65.103.100	-	VSPMF33	-	CS 1	DOWN

But it's a collection server ... so you have to look earlier in your log to find the work server that doesn't answer ...

[diegonix]

Correct, I can't send my finished WUs to the collection server.
The server is down since march 25, what will happen with my finished WUs?

[toTOW]

So what is the server (work server) that issued the WU ?

[bruce]

Correct, I can't send my finished WUs to the collection server.
The server is down since march 25, what will happen with my finished WUs?

Welcome to the foldingforum.org, diegonix.

The primary upload path should always be to the Work Server. Since you didn't mention that server, it's difficult to help you. What we're trying to tell you is that the Collection Server is a backup path which is only needed in case the primary path fails.

Please check the Server Status page before you try telnet and/or opening the default web page.

[diegonix]

Hey Bruce, thank you!
I understand the point and sorry for the dummie question, but where do I find what Work Server I'm using?

[diegonix]

Sorry, I forgot to set verbosity!

Here is the log with verbosity 9:

One answer, in FAHlog.txt file (take in look in your FAH folder). On the beginning of current Wu you willl find something like
[10:45:16] + Attempting to get work packet
[10:45:16] - Connecting to assignment server
[10:45:17] - Successful: assigned to (171.64.65.111)

If it was some older Wu, try FAHlog-prev.txt

Or simply visit http://fah-web.stanford.edu/psummary.html and under your Wu's number you'll find the server responsible.
