Status: O


Here's the final piece of the slip stuff I said I'd send you.  This script
sits in CRON and runs every 15 minutes.  It tries to ping my gateway 15
times and if that fails, restarts the connection.  If you want to use it,
you'll have to localize it.  The script "slipinet" it references is the
second piece of the mail I sent you - that part with the ifconfig's and such
in it.

Hope this stuff is useful to you.
