Hey Y'all,
I have the Stanford University Folding At Home project running on three
of my machines. I had them all set up so that I could control them all
from my main machine, 192.168.15.101, but some time ago something
changed so that I can no longer connect to the FAH clients on the other
two machines. I figured it wasn't really important so I would look into
it later. Well time has passed and my Christmas break is almost passed
too to I guess this is the time to figure it out.
I can still SSH onto both machines. I can ping both machines.
When I open the FAH Control on my machine connection to clients running
on 192.168.15.105 and 192.168.15.107 fails.
I'm assuming that there would be an entry in a log on those two machines
detailing the failed connection attempt.
What log file should I be looking at?

Perhaps there's a firewall (or SeLinux) getting in the way? Is it safe to assume you're running the same client version on all machines? perhaps even the latest? Oh, and pardon my noisiness, but what team are you folding for? If not Centos, have you considered joining the CentOS team? over the years there have been quite a few Centos folders, but now it's down to just three of us.

Do any of you have a GPU that is actually folding in CentOS 6? If you do please tell me exactly what video card and what driver you are using? I have a GeForce 9600 GT card that will not fold. FAH finds the GPU and sets up a slot for it but it always says "Update Core" in the slot status field with zero progress. I'm not happy with that. -- _ ?v? /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Do any of you have a GPU that is actually > folding in CentOS 6?I tried GPU folding in Centos-6, but the FAH log file showed continuous errors for the GPU (which was, at the time a Nvidia n460GTX). Inquiries on the FAH forums indicated that there are library incompatibilities on Centos-6 and that it would be difficult or impossible to make it work. I eventually upgraded to Centos-7 and then easily got GPU folding to work on the same video card without difficulty. FYI, I had previously (couple of years ago) attempted GPU folding on C6 using a 9800GT, and was told (again, on the FAH forums) that that GPU was no longer supported. I'd guess that your 9600GT is also too old. Here's the FAH forum thread on that GPU compatibility issue: https://foldingforum.org/viewtopic.php?f=80&t=25284&p=252427&hilit=9800GT#p252427 I've recently replaced the 460GTX with a new 750ti card, and found two amazing benefits: 1. according to my KillaWatt meter, the computer's power draw dropped from 275-295 watts to 190-195 watts, 2. my PPD total per week has gone from around 200K to more like 400K. In fact, the last 3 weeks have all been around 440K, some slightly lower, some a little higher. The 750ti was a fairly cheap card, at $129.> If you do please tell me exactly what video card and what driver you are > using?I'm using the Nvidia 340 driver from the elrepo repository.

I'm not happy with that.See above for compatibility comments on this card. -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- "For him who is able to keep you from falling and to present you before his glorious presence without fault and with great joy--to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore!
