    Why do you want it to run as root? It really shouldn't. Try hacking my installer, it should only be necessary to change the "fah_dir" variable in a few places to make it use the folder of your choice. As for running as root, I went through a lot of trouble to make sure it doesn't need to run as root. You would need to hack the foldingathome init script and the reconfigure script. The really quick and dirty way is to use su (read the man page).

    You can give it a command line option to finish the current unit and send and quit: '-oneunit'. If using my installer, you would this option to the /etc/default/foldingathome file and restart.

    Thanks for the reply

    Perhaps I don't mean as root. I installed it using the script in the wiki. It installed to /opt but I would like to wipe my / partition. /home is on a separate partition so if I could somehow copy it there that would mean I could keep my current work unit. I'll have a look at the scripts and stuff and see how I get on.

    That's easy. It's a good idea to shutdown the client before backing up.

    Re: Howto setup Folding@Home

    hey fellow folders!
    i recently installed the fah client on my laptop, along with some nice cpulimiting.
    i posted a pretty thorough howto about it on my ubuntu chronicles page here:
    http://pykeylogger.sourceforge.net/w...5D_on_a_Laptop
    in case anyone is interested.

    i have it running at 50% cpu load - that keeps the cpu nice and cool (otherwise, fan keeps revving up if i just let it run at 100% idle load), so that should prevent any premature death due to folding.

    hope this comes in handy for some of you.

    Re: Howto setup Folding@Home

    Hey thanks it WAS useful. I kept trying to install the program for the past couple of hours with scripts that didn't seem to be up to date and when I read your description saying "it simply boils down to" I was finally able to make it run.

    So thank you !

    Next time I'll have to make it run in the background. But enough for today

    Are those scripts the ones from the wiki? Can you describe what went wrong?

    What I meant was that I tried to use both fah_install and finstall to install folding@home and yes, both didn't work.

    The ubuntu one went wrong when I had to enter the install command:
    Code:
    sudo ./folding_install.sh install
    The command didn't exist apparently. I managed to install it by changing the commands to something else so the wiki wasn't up to date it seems. After some tinkering I made it but I wasn't sure how the files were installed so I kind of panicked and managed to uninstall everything. So yeah in the end I think I did it but since I didn't understand what the script was doing I didn't like it.

    As for the finstall I received a 404 not found when I tried to get it.

    What I finally did was to download f@h manually and start it from its own folder with the terminal. I wish I could make it run in the background though but it's not too much of a problem for now. At least I know where all the files are.

    You are absolutely right that the wiki was out of date. Thanks for pointing that out.

    The README mentions which files and directories are created during installation.

    Well I'm glad I helped the community then

    Also you are right about the README. I guess I was expecting to find my folder organized like in windows and that's why I ended up not using the script in the end.

    I've just found out you are the coder for the script so kudos to you !

    Re: Howto setup Folding@Home

    Hi, I'm a total noob to Linux, but I managed to follow the instructions on installing, but I can't get it to run, I get this in Terminal after entering sudo /etc/init.d/foldingathome start :

    /etc/init.d/foldingathome: 23: [[: not found
    /etc/init.d/foldingathome: 33: [[: not found
    /etc/init.d/foldingathome: 147: [[: not found
    /etc/init.d/foldingathome: 147: arith: syntax error: "++num"


    ?

    I really want to get this running as I have this computer doing nothing and rather put it to good cause.

    Thanks!
