I have tried re-installing Ivo's finstall (Thank you, Ivo!) to no avail; the only change
in repeated attempts is that sometimes the run hangs after

instead of after " - Connecting to assignment server"

Is there anything constructive that I can do about this?

Many thanks.

Replace the parameter string "-smp" with "-smp -verbosity 9" so that your log shows which server the client is trying to contact. Once you get an ip address, try opening the address in your browser and/or check the status of the server on psummary.

Hi codysluder,

Thanks for your reply. I added "-verbosity 9" to the parameter string
and ran "/home/folder/fah/folding start" again, with this result:

and then

[folder@Jerry ~]$ ping assign.stanford.edu
PING vsp10v-vz00.stanford.edu (171.67.108.200) 56(84) bytes of data.
ping: sendmsg: Operation not permitted

gave me the ip (171.67.108.200) and putting http://171.67.108.200:8080
into Firefox gave me a big bold OK. Scanning
http://fah-web.stanford.edu/serverstat.html for that ip yields
STATUS accept and CONNECT Accepting but nothing more in fahlog.txt
(after waiting 15 minutes).

What now?

[codysluder]

I'm not a linux guru, so somebody else will have to explain what "Operation not permitted" means. I am able to ping assign.stanford.edu and that does get translated into PING vsp10v-vz00.stanford.edu and I do get replies from 171.67.108.200.

Obviously something is blocking the connection to assign.stanford.edu.

Many, many thanks, codysluder; you didn't fix it but you got me thinking in
the right direction. That's much more beneficial than merely fixing it.
I still don't know precisely what went wrong, and I surely have not fixed it,
but I have made an end run around the problem; Jerry is up and folding again.

I made a new MEPIS installation on a new partition and copied /home /and
/root and a few files to it, then booted it and started folding. Marvelous!
Now I can work on this problem at my leisure without sacrificing folding,
or just wait for it to recur before spending more time on it.

You gave me precisely the help I needed. Thank you!
