Hi all,
This is a redial script I wrote the other night, which redials after the
link drops out but backs off exponentially if redial attempts keep
failing. (In Australia, we pay 25c per call, so if the other end is
answering but there's some sort of PPP problem, constant redials could end
up costing $$$). Redial delay is capped at 300 seconds maximum.
Basically the delays for repeated failed attempts will go something like:
5, 15, 45, 135, 300, 300, 300...
Once the link has been up more than 10 minutes, it is considered "stable"
and the redial delay is reset to 5 seconds when it next drops.
I'd be interested in any comments. Feel free to use it yourselves. To run
it in the background use '&' on the commandline. (the info messages could
probably be >>'d to a log file).
#!/bin/sh
delay1=5
while :
do
stime=`date "+%s"`
# use your own pppd options here, but make sure you have -detach

etime=`date "+%s"`
connectedtime=`expr ${etime} - ${stime}`
echo "time connected=${connectedtime} seconds"
if [ "`expr ${connectedtime} \< 600`" = "1" ]; then
delay1=`expr ${delay1} \* 3`
echo "delay now ${delay1} seconds"
if [ "`expr ${delay1} \> 300`" = "1" ]; then
echo "capping delay at 300 seconds"
delay1=300

if [ "`expr ${connectedtime} \> 600`" = "1" ]; then
echo "resetting delay to 5 seconds"
delay1=5
fi
echo "sleeping ${delay1} seconds"
sleep ${delay1}
done
