Folding via SSH

[HappyCracker]

I have F@H running on two machines, one is an XP box, the other RedHat9. To use the RH box, I SSH/VNC into it and run stuff that way. If I quit either of these programs, will Folding stop? Thinking it might be time for a small speed increase....Thanks! BTW, just busted 274 today! Oh, and while I have you, I want to set up my dual PPro box to do this stuff also, but only have one PCI NIC, whereas my notebook has the wireless and the 10/100. How would I control the PPros? I only have one kb/mouse and that's staying right where it's at, on the XP box. It wouldn't seem like they could be on the same net (192.168.0.x) so if I put them on a different one (say 192.176.0.x), how would I get to it.
Okay, I'm done for real this time. Cheers!

To answer your question: I don't know. However, if it does quit(that is, if when you start it, it has a contant output to the terminal vs. giving you CLI access again, ala Seti), then what should work is running it as <program name >> /dev/null &. This will pipe the output to /dev/null, and run it in the background, which is how I run Seti in "quiet" mode on my MacOS X machine. No garuntee, but I don't see why it wouldn't work.

Thanks man, will give that a try. I don't know how different the command line interfaces are. I thought in Linux it was the '|' button. I am not doubting you, in fact, I'm doubting myself more because I'm new to this Linux game. It just seemed like the easiest way for me to get what I want which is a ghetto home network (except the computers aren't cheap of course). Not that I have anything against screwing MS, I just figured I'd give them a break with having XP running on multiple boxes. I'll quit talking now. Thanks again!

MacOS X may use different terminology, but I believe it would be said that >> redirects the console output to /dev/null. Actually, IIRC, when used with an actual file, > overwrites and >> appends. The vertical bar ( | ) is known as the pipe, and that is used to send the output of one program as input to another program. Thus, "ls -a | less" is used, not "ls -a > less" when you want to send the output of ls to less.

However, in his case, he does want to use "./fah3console.exe > /dev/null &" (don't do that the first time you run it, because it needs to ask you some questions; also, be sure to start it every time in the same folder, preferrably the folder where the executable is kept, or your work files will get messed up).

FWIW, I have no idea why they put .exe onto the end of the Linux executable; maybe they've stopped doing that lately, but they hadn't the last time I checked. HC, if you're wondering why this makes any difference, it is because Linux identifies executable files by having the attribute +x, not by file extension. If fah3console does not run for you, you may need to set it to be executable. Do this with "chmod a+x fah3console.exe" and you should be good to go. 🙂

No it runs okay, I just didn't want to reboot this machine (the one i'm accessing the Linux box with) and not be able to get back in because then I would have to do a hard reboot on the Linux machine losing all work done. One thing I've learned from my little experiment is that a P2 400 running F@H gets smoked (well duh, but still) by an Athlon 2500. If you calculate the speed difference, it's about 4.5 times faster and that's really how long it takes the laptop to do a work unit. Owned. Interesting to see how far computers have come since 1999. But anyways, thanks j. Are you running this gig yourself? I notice you give the stats everyday, and those are much appreciated.

Oh, definitely not. The fine people over at Stanford are the ones who run the project. I'm just a normal person like you all.

The only reason I am the one doing the stats is because a long, long time ago (well, back in October of last year), I came back to Folding@Home after a year of experimenting with SETI, RC5, and ECCp-109, and found the client much improved from when I had originally tried it, so I decided to stay. Unfortunately, many of our active crunchers from times past (in those days we were 17th in overall team rank) had left to help with a race in another project, and then they never came back. 🙁

Since I noticed a general trend that projects which posted stats daily had more participation, I decided to give it a try since nobody else would step up and do something better (and trust me, there are plenty of ways the stats could be improved if only I had the programming knowledge). Although the TeAm hasn't seen the tremendous growth in members and output over a very short period that we saw originally, we do seem to be doing better when it comes to adding production and keeping it; I checked into it just now, and found that we have went from producing an average of 558 per day (back in October) to 3840 per day this last week. That's really quite amazing, IMHO. 🙂

Depending on the program that may or may not work. It works fine for chessbrain, doesn't work for some other programs I've tried. A better way would be to put that in an init script, so that it starts every time you start linux. You could also do a cron job that checks to see if it is running and start it if it isn't.
