Dial-on-demand SLIP/PPP daemon

[Chris Herborth <herborth@53iss6.Waterloo.NCR.COM>]

I just saw this in comp.os.linux.announce, and thought the MiNT-list might
be interested (at any rate, I'd be interested in this for MiNT-net!).

Here it is:

I have recently been doing some spare time work on on a daemon to support
dail on demand for both SLIP and PPP links under linux. The daemon
may also work on other platforms, but I can't give and guarrentee's.
My work has now reached a stage where I am ready to do some alpha testing.
If you are interested in testing this code you can find it at:

sunsite.unc.edu:/pub/Linux/Incoming/diald-0.1.tar.gz

Eventually it should move to:

sunsite.unc.edu:/pub/Linux/system/Network/serial/diald-0.1.tar.gz

Sorry, there are no precompiled binaries in this distribution.

There are some known problems with this release:

* It won't support SLIP links with dynamic IP assignment.
* When using a PPP link if it goes down and comes back up
  (the deamon will force a restablish) your existing TCP
  connections may be frozen. This seems to be a problem in the
  kernel routing code.
* The daemon can go into a loop attempting to restablish
  a connection forever if your modem gets wedge. The daemon
  should really time out.
* The daemon attempts to do a fast link take down when there
  are no TCP connections (6 seconds idle time by
  default). This has two problems:
  - the daemon only knows how to count the total number of TCP
    connections on your system, so if you have a local net the
    number of connections may never go to 0.
  - services that use connectionless protocols, such as Mosaic,
    may cause the link to spend a lot of time going up and coming down.

Suggested fixes to any of these problems are welcome!
