I thought I would return some effort to the list after all I got out of it,
so... here's my suite of automatic redialer scripts.  They ride on and depend
on the PPP scripts that come with the distribution.

----script 1: multidial----
#!/bin/sh

# This is a script to loop through the call to ppp-up until connected
# or times out (about 5 minutes as coded here)
#
# Jonathan Markevich Feb 1998
#

COUNTER=60
localip=0.0.0.0 
remoteip= 
device=/dev/modem 
pppflags="57600 modem defaultroute"

# Loop until PPP is established

while [ ! -e /var/run/ppp0.pid ]
do 
        if test $COUNTER -gt 0
        then
                # call ppp-up.  If already running it will be
                # ignored.

                /etc/ppp/ppp-up
                sleep 5
                let COUNTER=$COUNTER-1
                continue
        else
                # exit with an error code

                exit 1
        fi
done

# PPP has been established but wait until connection stabilizes.
# Use YaST to set up your NNTPSERVER environment variable first!

COUNTER=0
while ! ping -c 2 $NNTPSERVER &> /dev/null
do 
        sleep 1
        if test $COUNTER -eq 60

        then
                # Exit with error code after 60 seconds

                exit 1
        fi
        let COUNTER=$COUNTER+1
done

exit 0
---------------------------


----script 2: maildial----
#!/bin/sh

# braindead example script of how to use script 1
# Note: fetchpop is not a SuSE package!

if /etc/ppp/multidial
then
        # it worked! Transfer the mail.
        fetchpop -r -a
        sendmail -q
        /etc/ppp/ppp-down
fi
--------------------------

----script 3: hangup----
#!/bin/sh

# Just made to kill the dialing if it really needs it!
kill -SIGINT `ps | grep "/usr/sbin/chat" | gawk '{ print $1 }'`
------------------------

Please let me know if you can see any improvements.  I am just learning shell
scripting!

Thanks!
