Using Dialup Configuration Tool to configure a PPP Connection
To configure a PPP connection, you need only know a few parameters:
- The phone number of your ISP
- Your username
- Your password
If you have more than one modem, you will also need to select the one to use.
Checking your PPP connection
To debug your PPP connection or simply to better understand how it works, you can run through the steps
below. They will help you understand where information is being stored and how tools can be used to track
Check that your PPP interface is working
One way to do this is with the ping command. From the Terminal window, type ping along with any Internet
address you know. For example:
PING handsonhistory.com (220.127.116.11) from 192.168.0.43 : 56(84) bytes of data.
64 bytes from handsonhistory.com (18.104.22.168): icmp_seq=0 ttl=240 time=120 msec
64 bytes from handsonhistory.com (22.214.171.124): icmp_seq=1 ttl=240 time=116 msec
64 bytes from handsonhistory.com (126.96.36.199): icmp_seq=2 ttl=240 time=120 msec

4 packets transmitted, 3 packets received, 25% packet loss
round−trip min/avg/max/mdev = 116.816/119.277/120.807/1.779 ms
Press Ctrl+C to end the ping command. The lines above show the responses from http://www.handsonhistory.com.
It sent back packets from the IP address 188.8.131.52 in response to each one
it received. You can see the sequence of packets (icmp_seq) and the time it took for each response (in milliseconds).
If you receive packets in return, you will know two things: first, that your connection is
working, and second, that your name to address translation (from the DNS addresses in /etc/resolv.conf) is
RP3 Configuration Tool
You can also set up a new dial-up connection with the RP3 configuration utility by typing rp3-config at a command prompt. The next lesson shows you how to activate a PPP connection.
