>Description:
iij-ppp (aka userland PPP) should use the /etc/ppp/ip-up and
/etc/ppp/ip-down scripts when the link goes up and down. It
should give these scripts the exact same argument list as pppd
does. (for compatibility -- I use both pppd and iij-ppp on the
same system, and switch whenever it suits me. Or think of the
guy who wants to switch FROM pppd TO iij-ppp without having to
rewrite his scripts!)
The reason why the ip-up/down script arguments are important is
that some programs you may want to run in these scripts require
arguments. An example (one that I actually use) is with the
Monolith DYNDNS service (http://www.ml.org/), which allows users
with dynamically-assigned IP addresses (i.e. a PPP account with
a ISP) to have their own domain name (e.g. mydom.dyn.ml.org).
You need to run a client every time you dial in, so that the
Monolith nameserver knows about what IP address you're using now.
This client requires, among other data, the IP address of the
PPP connection to be passed in as the argument.
Other useful uses for the /etc/ppp/ip-{up,down} script are (some
of which I actually use): writing all users (wall) when the
connection goes up and down, starting SUCK (to grab nntp news),
running 'ping <some_ip>' to keep the connection up all the time,
etc.
