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 (““) indicates that the file /etc/passwd can be used 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/ttyMUE0 115200 crtscts modem 192.168.16.1:192.168.16.2

respawn command.
