How do you say "Dial on Demand"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<P><STRONG>
This may be really trivial for unix gurus, but I can't contain my
excitement at having successfully routed my small office LAN
through my linux box to a single ppp account! Broadband's too
expensive and before I got this set up we were running around
telling each other to hang up coz we needed to check our
e-mail! Heh, now we can all surf the web at the same time.
This is no small feat for a Mac user.

But I have one challenge which I think I'm going to need some
help with. On a Mac I can get the PPP client to dial the ISP
automatically when a TCP/IP application starts up and needs
to connect to the internet. How do I do this on linux?

The feature you're asking for is called "dial
on demand." Under Linux this used to require
an additional package called '<tt>diald</tt>'. However,
it is also now a built in feature of the PPP
daemon (<tt>pppd</tt>).
</BLOCKQUOTE>
<BLOCKQUOTE>
Search the <tt>pppd(8)</tt> man page for the term "demand"
and read through that a bit.
</BLOCKQUOTE>
<BLOCKQUOTE>
I notice that Al Longyear's PPP FAQ is desparately
out of date and should be updated sometime soon.
It still refers us to diald. Of course you <EM>can</EM>
still use diald in any event, but you should be able
to simply add the "demand" keyword to your
<TT>/etc/ppp/options</TT> file.

Hope that helps.
