# DIR is the directory where the ppp0.pid is found when ppp is running.

# FILE is just what it says.

# for a in `ls $DIR`  causes the script to read every file in the directory
# $DIR

# the next three lines starting with do and ending with exit, fi and done;  
# says if a file in the directory matches ppp0.pid then exit the script
# because the PPP is up and running.
# If none of the files in the directory are the ppp0.pid then it goes to
# killall ping and kills any pinging that's going on then calls the dialer.
# I use dip. Put whatever you use as a dialer in here. Use full pathes just
# to be sure.

# why the pings, you say?
# I use a ping every ten minutes from the crontab to show my ISP activity.
# Sometimes, though not very often, I will still lose the connection and the
# ping will continue to operate. I don't know why this happens but I can use
# ps -aux and see that there are pings running even though I only send 5
# pings at a time with ping -c 5. And they will continue to run until I stop
# them with a kill signal. This doesn't happen with the phone line active.
# go figger.  Anyway I expect YMMV!   (:   


# This is nothing but a script to keep your machine on line. It doesn't do
# anaything else. If you need on demand dialing you'll have to look
# elsewhere.

# This file should be called by your crontab like this:
#
# */5 * * * *  /usr/local/bin/redial &> /dev/null
#
# This calls redial every 5 minutes to see if ppp is up. then it sends
# all messages to /dev/null instead of your mailbox. Although you may want
# to leave '&> /dev/null' off until you are sure it is running properly.
