Shell Script for PPPing to TRC

Warning! This page is only for TRC people. PPP connection to TRC Unix machines is not allowed for other people. However, other people may copy and modify the scripts.

O Explanation

This page contains shell script for PPP connection from a Linux box to TRC Unix machines. The first script is for normal PPP connection. The second is for call-back connection. The third is used by the first and second scripts. The name of this script is trcppp.

You have to replace ||...|| by the host IP address that you want to connect, the phone number of the host, your user id, and your password.

The script works (at least on my Linux bos), but may have bugs. Sorry!

O Normal PPP Connection Script 

#!/bin/sh
PHONE_NUMBER=||XX-XXXX||	# Phone number for sh1, sh2 or ...
PPP_HOST=||163.220.1.10||	# 163.220.1.10=sh1, 163.220.1.9=sh2, ...
PPP_UID=||user id||
PPP_PASSWD=||password||
CALLBACK=
export PHONE_NUMBER PPP_UID PPP_PASSWD PPP_HOST CALLBACK
PPP_ABORT='ABORT "NO CARRIER" ABORT BUSY'
trcppp

O Call-back PPP Connection Script 

#!/bin/sh
PHONE_NUMBER=||XX-XXXX||	# Phone number for sh1, sh2 or ...
PPP_HOST=||163.220.1.10||	# 163.220.1.10=sh1, 163.220.1.9=sh2, ...
PPP_UID=||user id||
