If your output looks similar but doesn’t have the destination 0.0.0.0 line (which refers to the default route used

for connections), you may have run pppd without the ‘defaultroute’ option. At this point you can try using

Telnet, ftp, or finger, bearing in mind that you’ll have to use numeric IP addresses unless you’ve set up

/etc/resolv.conf correctly.

Setting up a Machine for Incoming PPP Connections

This first example applies to using a modem, and requiring authorization with a username and password.

pppd/dev/ttyM0 115200 crtscts modem 192.168.16.1:192.168.16.2 login auth

You should also add the following line to the file /etc/ppp/pap-secrets:

* * ““ *

The first star (*) lets everyone login. The second star (*) lets every host connect. The pair of double quotation

marks (““) is to use the file /etc/passwd to check the password. The last star (*) is to let any IP connect.

The following example does not check the username and password:

pppd/dev/ttyM0 115200 crtscts modem 192.168.16.1:192.168.16.2

PPPoE

1. Connect the RTU controller’s LAN port to an ADSL modem with a cross-over cable, HUB, or switch.

2. Log in to the RTU controller as the root user.

3. Edit the file /etc/ppp/chap-secrets and add the following:

“username@hinet.net”*“password”*

“username@hinet.net” is the username obtained from the ISP to log in to the ISP account. “password”

is the corresponding password for the account.

4. Edit the file /etc/ppp/pap-secrets and add the following:

“username@hinet.net”*“password”*

“username@hinet.net” is the username obtained from the ISP to log in to the ISP account.

“password” is the corresponding password for the account.
