The PPP-TIP was written specifically for Red Hat 3. A new version is in
preparation for Red Hat 3 & 4. However, the need for this tip in Red Hat 4
has possibly reduced as the netcfg tool now does PPP properly (as I
understand it).

If you are using Red Hat 4 you should NOT attempt to use the scripts
outlined in the PPP-TIP! Things have changed with Linux kernel 2.0 and
PPP-2.2. Check the PPP-HOWTO (V2.2) that covers both kernel 1.2.x and
2.0.x.
As to starting the PPP interface at boot time...and keeping PPP alive
permanently
1) Use the PPP-HOWTO scripts.
2) Create /usr/local/scripts (mode 744 - this is the admin scripts
directory) owned by root, group root.
3) In that directory, create a script like...
---------------------------------------------
#!/bin/bash
#
# This script fires up the permanent PPP link and restarts it if it fails.
# It uses the /etc/ppp/scripts/... ppp start up script

# iweft@ipax.com.au
#
# See the PPP-HOWTO (http://203.29.72.65/ for the latest version) for more
# Information on setting up the /etc/ppp/... scripts.
#
#
LOCKDIR=/var/lock
DEVICE=cua1
if [ -f $LOCKDIR/LCK..$DEVICE ]
then
rm -f $LOCKDIR/LCK..$DEVICE
echo "Removing stale lock files"
fi
while sleep 5; do
/bin/setserial /dev/ttyS1 spd_vhi
/etc/ppp/scripts/ppp-ipax-perm
rm -f $LOCKDIR/LCK..$DEVICE
done
----------------------------------------------------
Make this file mode 744 (owned by user root, group root) and name it
Do_Internet.
4) In /etc/rc.d/rc.sysinit add an invocation of this script at an
appropriate place. For example, towards the end of rc.sysinit, there is an
invocation of rc.serial (which correctly does special initialistaion of
the serial ports - if YOU write the script). Immediately after this is a
good place to start up PPP (as the file system is fully mounted,
special modules loaded, clock set etc etc). So After the call to
rc.serial, insert the lines
------------------------------------------------------
# Start the Internet link
if [ -x /usr/local/scripts/Do_Internet ]; then
echo "Starting the Internet link."
/usr/local/scripts/Do_Internet &
fi
------------------------------------------------------
Hope this helps.
A revised Red Hat PPP-TIP will be announced here shortly. It will be
available on the InterWeft Web site at http://203.29.72.65/ as soon as
announced and on the Red Hat site as soon as they have time to add it!
