Then make /etc/ppp/Autostart

look like this:

#!/bin/sh

PATH=/usr/etc:/bin:/usr/bin

if [ -f /var/adm/pppd.log ]; then

mv /var/adm/pppd.log /var/adm/OLDpppd.log

echo -n "Starting PPP daemons:" >/dev/console

pppd oursystem:backbonesystem auto up

(echo -n ’ backbonesystem’) >/dev/console

pppd oursystem:theirsystem auto idle 120

(echo -n ’ theirsystem’) >/dev/console

echo ’.’ >/dev/console

To allow a PPP implementation running on ‘theirsystem’ to dial into ‘oursystem’, insert the following into

/etc/passwd on ‘oursystem’:

Pthem:?:105:20:Their PPP:/etc/ppp:/etc/ppp/Login

where group 20 is the gid of the ppp group which owns /usr/etc/pppd, and

/etc/ppp/Login is an execut-

able shell script that looks something like

#!/bin/sh

PATH=/usr/bin:/usr/etc:/bin

exec pppd ‘hostname‘:

RECOMMENDATIONS

Use host names when running

/etc/ppp/Autostart

from /sbin/rc2.d/S522ppp only if they

are known locally. If a PPP connection to a DNS server would be required to resolve a host name, use its

literal IP address instead.

EXTERNAL INFLUENCES

Environment Variables

The environment variable

PPPHOME, if present, speciﬁes the directory in which pppd looks for its

conﬁguration ﬁles (

Filter and Auth for all connections, along with Systems, Devices

, and

Dialers if the connection is ‘outbound’). You can specify PPPHOME either in the Autostart

script or

in an incoming connection’s

script. If PPPHOME is not present, pppd will expect to ﬁnd its

conﬁguration ﬁles in

/etc/ppp/* .

SECURITY CONCERNS

pppd should be mode 4750, owned by root, and executable only by the members of the group containing all

the incoming PPP login ‘users’.
