Installing and Administering PPP

38 Chapter 2

Setting Up PPP Connections

Conﬁguring Inbound Connections

Look carefully at the last line in the sample script shown below. Notice

that the word 'hostname' is surrounded by backquotes, not regular

quotes or apostrophes. `hostname`, with the backquotes, tells the system

to insert the output of the command hostname(1) in this space in the

pppd command line. We recommend that you make sure backquotes are

used by copying this script from /etc/ppp/Login.ex, rather than

inserting them manually.

#!/bin/sh

# PPP login shell example

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

PPPHOME=/etc/ppp

export PATH PPPHOME

mesg n

stty -tostop

exec pppd `hostname`:robin idle 150

hostname will return lark, the current machine, and robin is the peer.

The idle timer is set to 150 seconds. Refer to the pppd(1) man page for

pppd command line options.

Checking Permissions

Following the creation of the Login shell script, make sure the script is

executable with the following command:

# chmod 755 Login
