Projects / Xringd


The Linux Extended Ring Daemon matches "sequences" of a phonerings/timedelay confguration with rings and time delays coming from a modem. A fully matched sequence will execute a specified command. Thus, commands can be run while your modem stays on-hook. It could be used to make your system automatically connect to the Internet whenever you want.

    Re: this DOES work
    This program is VERY cool. Thanks to xringd / / ssh / mindterm I can now login to my
    home machine from anywhere providing I have a
    phone and a Java capable browser.

    A little experimentation with my mobile phone has
    shown that, in the UK at least the ring the caller
    hears and the ring the receiver hears correspond
    if not exactly then close enough for this to work
    a treat.

    One minor problem is that xringd doesn't work
    after pppd has exited. The solution is fairly
    trivial tho - just have a script restart xringd
    after pppd finishes and everything works fine.

    this may not work
    An important detail in how phone systems work is
    that the rining you hear when you call somebody
    is not synchronized with the ringing of their phone.

    Two different ringing signals are generated, one
    for your benefit, one to ring the actual phones.
    Often these are fairly close together but there
    are no guarantees.

    It may be necessary to characterize the average connection delay
    to make this communications mechanism robust.
