Thanks Tobit for the help


I have tried to get this machine going a couple of times. Once I just copied a folding folder I was using on a different machine over (which has always worked before) and it couldn't get work. So I DLed and re setup the client from scratch. Linux Fedora 12. i7 950 12 gigs of ram. Mild overclock since it is my work desktop machine. Oh and I fold on several other machines at work so this isn't a firewall issue. Most of my PPD is running at the office (gotta love small companies).

The only outage I can think of is DNS but I can resolve the addresses fine. (and so do my other machines at the office)

I have been fighting with this for about two weeks.

Oh and I am running that as root so permissions shouldn't be a problem but I have set them to 777 at one point to be sure.
 
Did you try another distro by any chance?
 
From my old config that I copied in from another running Fedora 12 system. I have been getting this same error on and off for a week plus every time I try. I can use a web browser to open those pages and they give some generic hello message but not connection refused.

And from the old install that has a client number (which I deleted from this screen copy for the time being).

Appears to be a local to you network issue, firewall setting perhaps, as you are not able to even connect to the assignment server. Not familiar enough with the specifics of Fedora 12 to know where to lead you but it is a network issue of some kind.
 
From my home web browser here at home on http://assign2.stanford.edu:80/
I get
OK

when I wget the same page via command line

I get an OK back so it seems to be connecting.

From one of my other work boxes running Fedora 12 which works fine and has been for quite a while.

Soft firewall is on on my desktop but not the server. Might as well fix that and see if it fixes it.

Update
Softfirewall is now off and I get the same output. I am pretty sure I disabled selinux but I am sure it is in permissive mode at least. Yeah I am annoyed I can't get this box to fold. It is doing nothing most of the time even when I am at work! (terminal sessions don't eat much cpu).
 
Ok, on Fedora 11 and 12 it looks like you need to open the file /etc/nsswitch.conf and look for the line that begins with 'hosts: '

Code: 
hosts:     files mdns4_minimal [NOTFOUND=return] dns

and change it to:

Code: 
hosts:      files dns
 
I haven't changed it and the line you mention is correct. (I do notice "bootparams: nisplus [NOTFOUND=return] files" and wonder if it needs changed)?

passwd: files
shadow: files
group: files

#hosts: db files nisplus nis dns
hosts: files dns

bootparams: nisplus [NOTFOUND=return] files

ethers: files
netmasks: files
networks: files
protocols: files
rpc: files
services: files

netgroup: nisplus

publickey: nisplus

automount: files nisplus
aliases: files nisplus
 
No, bootparams doesn't need to be changed.
 
Try these two commands as root (or via sudo)

chkconfig nscd on
service nscd start
 
Quote from Folding Forums.

"Ok, how about this:
The fah6 binary is statically linked. Due to the fact that even so some parts of the c library are dynamically loaded at runtime, it is somewhat incompatible with newer versions of glibc. Especially the domain name resolution does not work, which prevents contacting the assignment server and getting any WUs; the symptom of this is the error message "Could not CosmHTTPOpen".
There is a workaround for this which creates a patched version of glibc; that stopped working as of glibc 2.12. Symptoms include segfaults, floating point exceptions or the core exiting with status 0.
But there is another workaround: glibc comes with a caching daemon, called nscd, which communicates with the applications via socket and does the resolutions on their behalf. glibc, namely gethostbyname, automatically uses this daemon if it is running. So to get fah6 working, you just have to enable nscd. For Fedora (and similar systems) this is done by
CODE: SELECT ALL
chkconfig nscd on
; if you don't want to restart your system, also do
CODE: SELECT ALL
service nscd start "

And it was just nscd wasn't running! So what I was interpreting as a DNS issue. Man that was an easy fix.

Thanks for the help guys. Another Linux box for the [H]orde
 
Awesome you were able to resolve the issue and thanks to Tobit for helping out. :cool:
 
My work desktop

I7 950 running a mild overclock of 3.26 due to it being my work desktop and having a stock heatsink.
It has 12 gigs 3x4 from Mushkin Silverline 1333 and that doesn't OC very well. (big and slow works in this situation) Above 143 I lose two sticks. 140 bclck currently

Asrock X58 Xtreme
GT240 512 meg DDR5 (work machine with nice dual head)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125304&cm_re=512_240-_-14-125-304-_-Product
Kingston 64 gig SSD
WD Black 2 TB

Whole wish list at the egg
http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10033189
although the monitor changed slightly and I got the ram from Mushkin directly because it was cheaper and the support is better that way.

It is a work desktop that can virtualize Win 7 Pro along with various other OSes. Main function provide me with terminal sessions to go out to servers with. Then I need some windows crap so I either rdp in to something or run a virtual machine.

The previous machine I was using was an HP Athlon 64 x2 running 1.8 or so GHz with 2 gigs of ram max which barely ran itself. I am not missing it!
