Run folding as service

**Outlaw** · 03-04-2006, 11:37 PM

Don't know if similar exists, but here's a way to automate starting of Linux folding at home client for Deb and Fedora. Let me know If someting needs to be fixed. Not sure how to make sticky. Will a moderator please make sticky.

This is a way to use folding as a service in Linux if you prefer to have folding start automatically.

===================
Debian Instructions
===================

Download the Linux folding client
Place in /usr/local/bin
as root, run for first time manually and enter your user name and the team number. Then kill with ctrl-c

then copy and paste this script into /etc/init.d/folding

Code:

#!/bin/bash
#
# Start Folding At Home execution
#

FAH=/usr/local/bin/FAH504-Linux.exe

check_binary() {
    if [ ! -e /usr/local/bin/FAH504-Linux.exe ]
        then
            echo "Folding binary is missing or has changed"
        exit
    fi
}

check_running() {
    COUNT=`ps -ef|grep [F]ah|wc -l`
    if [ $COUNT = 4 ]
    then
        RUN=1
    else
        RUN=0
    fi
}

case "$1" in
    start)
        check_running
            if [ $RUN = 1 ]
            then
                echo "Folding seems to be running already"
                exit
            else
                /usr/local/bin/FAH504-Linux.exe >/var/log/folding 2>&1 &
                exit
            fi
        ;;

    stop)
        check_running
            if [ $RUN = 1 ]
            then
                killall FAH504-Linux.exe
                exit
            else
                echo "Folding does not seem to be running"
                exit
            fi
        ;;

    status)
        check_running
            if [ $RUN = 1 ]
            then
                echo "Folding is running"
                tail -n 5 /var/log/folding|grep -i completed
                exit
            else
                echo "Folding does not seem to be running"
                exit
            fi
        ;;
esac

Use sysvconfig to add folding to startup

Code:

Great, thanks. I will put that into my Ubuntu desktop.

**Compunuts** · 03-05-2006, 06:56 AM

Oh and when WiKi got working again, we can put that into DC WiKi as well.

Done

**Compunuts** · 03-06-2006, 08:07 AM

I was doing it and only got it to creating headlines. Then my mouse in WinXP got stuck (can't copy and paste).

**Compunuts** · 03-10-2006, 05:53 AM

I'm using Ubuntu 5.10 and it didn't install sysvconfig package by default. One need to issue "sudo apt-get install sysvconfig" first before trying to configure F@H to start up.

I can't add this info to WiKi ATM so I'm just keeping a note just in case.

Good catch, added.

One more question, does your script automatically create "folding" log file in /var/log ? If not, then one need to manually create it. Right? Then what should permission be? I don't think doing 777 would be secure but 760? I'm not really familiar with file permission setting in secure environment.

**Outlaw** · 03-11-2006, 02:11 PM

You brought up a good point. That folding log file in /var/log is redundant in that a log is automatically generated by folding in the home dir of the user executing it. The reason I have it going to /var/log is to keep consistent with how services usually log.

To answer your question, the log file is automatically created by redirecting stdout and stderr to that file, and the permissions will default to root's umask. So it should default to 644 perms if you have the normal umask. The file will be wiped out each time the service is restarted, but that's not so bad since there's a log made by FAH in root's home that appends each time.

A mode of 644 is a little more permissive than you want for a secure env. Perhaps a chmod on that file to 600 is in order?

I added that chmod into the Wiki
