First of all, ppp.conf isn't used by pppd, it's used by 'ppp'. Are you
using pppd or ppp? If you're using the former, you want to create a
little shell script which loops forever and runs pppd. (And make sure
that you have /etc/ppp/options setup correctly). Here is my pppd
dialout shell script.
#!/bin/sh
#
# PPPD Auto-Dialer script
#
# Note:
# You *MUST* use -detach mode or else the pppd process will fork
# into the background and you will get hundreds of pppd processes trying
# to connect to the remote site. The current behavior causes the line to
# re-dial when pppd fails, so it acts like a auto-dialer.
#
DEVICE=cuaa0
while `true`; do
/usr/sbin/pppd sri.MT.net:micgate -detach \
connect 'chat -v -f /etc/ppp/ppp0/chat' $DEVICE 115200
# If we fail, wait a little while for the line to settle down
sleep 15
done
And, here is my chat script. Unfortunately, you have to build a custom
chat script for every outgoing connection, but you should be able to get
the idea here.
/etc/ppp/ppp0/chat:
ABORT "NO CARRIER" ABORT BUSY "" ATZ OK ATZ OK ATDT4432530 CONNECT "" \
ogin: ppp ssword: \qsecret
(The continuation line was put in there by me, it should be one complete
line in the file)
Finally, you need to figure out a way to call the script. One way to do it
would be to have it called from out of /etc/ttys, using a line such as this:
ttyd0 "/etc/ppp/ppp0/ppp-dialout" unknown off secure
Again, this is sort of a lie, since in fact it's not ttyd0 being used but instead
cuaa0, but you get the picture.
Hopefully this is some help,
Nate
