I'm curious how to get pppd to auto redial when my connection dies.
<snipalot>
Just respawning the pppd is not sufficient, I had times when pppd ran and
the ppp0 interface was visible but did not have an IP address. IMHO the pppd
should be changed that so it never quits, doesn't run twice on the same
interface and retries constantly. In the meantime, I'm using the script
below, called "pppwatch". If the ppp connection is down for 15 seconds, ppp
is restarted. Arguments are the interface (ppp0), the dsl-provider and the
ethernet interface. The script would have to be changed if you need more
than one ppp connection (sometimes it kills all pppds)
I have pppwatch in /etc/ppp/ and start it in /etc/network/interfaces:
auto ppp0
iface ppp0 inet ppp
pre-up ip link set eth1 up
provider cybernet eth1
up /etc/ppp/pppwatch ppp0 cybernet eth1 >/dev/null </dev/null 2>&1 &
#!/bin/sh
IFACE=$1 PROVIDER=$2 ETHFACE=$3
PIDFILE=/var/run/pppwatch-$IFACE.pid
echo "Watching $IFACE $PROVIDER $ETHFACE"
if [ -r $PIDFILE ]; then PID=`cat $PIDFILE` if kill -CONT $PID 2>/dev/null; then #already running exit fi fi
echo $$ >$PIDFILE
while true; do if ip addr show $IFACE | grep inet >/dev/null 2>&1; then else sleep 10 if ip addr show $IFACE | grep inet >/dev/null 2>&1; then else #at least 10 seconds without ppp
echo "$0: Restarting Networking, no $IFACE" |logger
PID=`ps axw | grep "[ /]pppd call $PROVIDER "` if test -n "$PID" ; then echo "$0: killing pppd" |logger killall -9 pppd fi
sleep 5 #try to restart ppp service pon $PROVIDER $ETHFACE
fi fi sleep 5 done
