Binary package “diald” in ubuntu intrepid
dial on demand daemon for PPP and SLIP
Many sites use SLIP or PPP links to connect to other sites over phone
lines. Normally these links must be explicitly turned on or off.
diald can be used to bring a SLIP or PPP link up when there are
Internet packets to be sent to another site, and to close the link
down when it is idle.
diald operates by starting a virtual link on a pseudo tty and setting up
a route to the resulting interface. This interface is called the
proxy. diald monitors the proxy to determine when to bring up a real
communications link. When a real link is up diald routes packets from
the proxy to the real link and monitors the real link to decide if it
needs to be shut down. As well, if the link goes down unexpectedly
diald will attempt to reestablish the link. The rules for controlling
these operations are extensively configurable in run time startup
Diald requires that you use either the ethertap interface (available
in recent Linux kernels) or SLIP to provide the proxy interface.
Thus, one or the other of these interfaces is required for diald to
Diald needs a program like "chat" or "expect" to actually dial.
Sorry, "dip" cannot be used.
