PPP dies early
I am doing my best to get a ppp connection with my
ISP working. I would have expected this to be fairly
easy, because my provider supports Linux and has some
scripts available for this purpose.
Unfortunately, this did not turn out as easy as I hoped.
My modem dials my provider and the script manages to get
me logged-in. I seem to receive an IP address for the session,
but after a second or three the line drops and I am lost.
Even during the 3 seconds 'on-line', ifconfig does not report
an ppp interface, so I assume that I am not really 'alive'.
I have added both scripts and a portion of the log file,
hoping that someone might be able to give me a clue where
to look for the problem. This would be greatly appreciated!
Best regards,
