Re: question about demand dialing with diald

[Michael Slack <mslack@xxxxxxxxxxxxx>]

Well this certainly clears up a lot of confusion on my part regarding the 
whole topic of demand dialing.  The ppp daemon is going down on disconnect, 
though I am not sure why.  I definitely appreciate your help on this.

Here is what I get in /var/log/messages:

Oct 27 08:22:34 penguin pppd[3383]: Terminating connection due to lack of 
activity.
Oct 27 08:22:34 penguin pppd[3383]: Connection terminated. 
Oct 27 08:22:34 penguin pppd[3383]: Connect time 14.9 minutes. 
Oct 27 08:22:34 penguin pppd[3383]: Sent 34776 bytes, received 249021 bytes. 
Oct 27 08:22:34 penguin pppd[3383]: Terminating on signal 2. 
Oct 27 08:22:34 penguin pppd[3383]: disconnect script failed 
Oct 27 08:22:35 penguin pppd[3383]: Exit. 
Oct 27 08:40:00 penguin kernel: PPP: ppp line discipline successfully 
unregistered

Here is /etc/ppp/peers/ameritech:

connect /etc/ppp/ppp-connect
disconnect /etc/ppp/ppp-off
/dev/ttyS1
115200
modem
crtscts
lock
defaultroute
mtu 552
mru 552
netmask 255.255.255.0
asyncmap 0
idle 300
user mslack
demand
192.168.0.1:192.168.0.2
ipcp-accept-remote
ipcp-accept-local
holdoff 10

and just in case, here is /etc/ppp/ppp-off:

#!/bin/sh
######################################################################

# Determine the device to be terminated.

if [ "$1" = "" ]; then
	DEVICE=ppp0
else
	DEVICE=$1
fi

######################################################################

# If the ppp0 pid file is present then the program is running. Stop it.
if [ -r /var/run/$DEVICE.pid ]; then
        kill -INT `cat /var/run/$DEVICE.pid`

# If the kill did not work then there is no process running for this
# pid. It may also mean that the lock file will be left. You may wish
# to delete the lock file at the same time.
        if [ ! "$?" = "0" ]; then
                rm -f /var/run/$DEVICE.pid
                echo "ERROR: Removed stale pid file"
                exit 1
        fi

# Success. Let pppd clean up its own junk.
        echo "PPP link to $DEVICE terminated."
        exit 0
fi

# The ppp process is not running for ppp0
echo "ERROR: PPP link is not active on $DEVICE"
exit 1
