DESCRIPTION



    killppp is a shell script that kills the ppp process after

    specified time of no traffic. This is especially useful

    for dial-up users who pay per time-unit of being connected.

    The typical use for it, is to start a large download along

    with killppp and go away. The script will shut down ppp

    after the downloading is done. Thus saving unnecessary

    cost of unused network connectivity.



    Depending on how your linux is configured you may need to

    be root to have the right to kill a ppp process and it may

    have to be the ppp daemon (pppd).



    To find the pid of your ppp process type: ps aux | grep ppp



    How this script works? Once activated, killppp checks every

    minute for network traffic on the ppp0 device. As long as

    data is passing through, killppp does nothing. Upon no 

    traffic killppp starts counting time until it reaches the

    specified time and kills the ppp process.



EXAMPLES



    killppp 8249 5m



    This will kill the process 8249 after 5 minutes of no

    traffic.
