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 W406-LX’s LAN port to an ADSL modem with a cross-over cable, HUB, or switch.
2. Log into the W406-LX 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.
