Re: testing ppp w/ debian

Hi James

I did this last week so while it's fresh in my mind ...
I was new to dial-in so it's unlikely to be the perfect solution, but it
seems to work.

Make sure you have ppp and mgetty installed. Both have good docs -
info mgetty (install mgetty-docs) and man pppd.

The last line of /etc/inittab (at least on my woody install) was a
commented out mgetty line.  Uncomment it and change to reflect your own
serial port. eg:

T0:23:respawn:/sbin/mgetty -x0 -s 57600 ttyS0

Run 'telinit q' to get init to start mgetty listening on your serial

For PAP you need to alter /etc/ppp/pap-secrets. For a user brian wanting
to login to machine zinc, add a line:

brian   zinc    ""

Finally - ignoring the steps I've completely forgotten about :) set up
/etc/ppp/options (or /etc/ppp/options.ttyS0 (0/1/2...)) to set the IPs
for either end of the ppp link eg:

Leaving first field blank will defualt to an IP address from the server.
Leaving the second field blank allows the client to set its own IP.
Other handy settings were 'defaultroute' and 'ipcp-accept-remote'.
/var/log/messages is useful for seeing how far you are getting with ppp.

The first time I dialled in my modem got into a strange state and it
wouldn't answer incoming calls. Dialling out with wvdial reinitialised
it prefectly.
