I've been watching this one from the sidelines, mainly because I'm having as
much trouble as lawson trying to figure out what you want to do. Questions
from lawson haven't gotten the needed clarification, so let's try going back
to basics.
Any ppp connection has two ends:
the "client" end makes a phone call and, on request,
authenticates itself to the other end
the "server" end listens for a phone call, ansswers
the phone, authenticates the caller, and (usually)
starts the LCP negotiation that will establish
call parameters. Commonly, the "server" assigns
IP addresses and often DNS server addresses, and
it is typically the default route for the "client".
I put "client" and "server" in quotes here because ppp is really a
peer-to-peer protocol, not a client/server protocol. Nonetheless, the
"client"/"server" usage is almost universal.
So, with this background ...
... which end of the ppp connection are you running? You refer to
"callback" -- are you the person attempting to implement a true callback
system (you call the other end, authenticate yourself somehow, supply a
phone number, and the other end calls it and tries to start a ppp
connection)? I no longer havve your prior messages to check, so I need to
play catch-up here.
... what method do you use to authenticate the connection (the three
standard candidates are userid/password (done in the chatscript on the
"client" end and in a script that precedes the start of pppd on the "server"
end), CHAP, and PAP (the latter two done by pppd)).
... what does a **complete** set of log entries for a connection
attempt look like? (Unabridged -- chat or login script AND pppd -- except
mask out any password that is recorded.)
... if you have access to the other end, what does a completre set
of log entries from that end look like? (Same proviso.)
... what options are you setting for the pppd connection (might be
/etc/ppp/options, or command-line arguments in a script that starts pppd, or
something else -- very distribution and implementation specific)?
