# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any# other accounts that should
not be able to use pppd!
guest hostname “*” -
master hostname “*” -
root hostname “*” -
support hostname “*” -
stats hostname “*” -
“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.
5. Edit the file /etc/ppp/options and add the following line:
plugin pppoe
# This wait period only applies if the connect or pty option is used.
#connect-delay <n>
# Load the pppoe plugin
plugin /lib/pppoe.so
# ---<End of File>---
6. Add one of two files: /etc/ppp/options.eth0 or /etc/ppp/options.eth1. The choice depends on which
LAN is connected to the ADSL modem. If you use LAN1 to connect to the ADSL modem, then add
/etc/ppp/options.eth0. If you use LAN2 to connect to the ADSL modem, then add
/etc/ppp/options.eth1. The file context is shown below:
name username@hinet.net
mtu 1492
mru 1492
defaultroute
noipdefault
~
Type your username (the one you set in the /etc/ppp/pap-secrets and /etc/ppp/chap-secrets files)
after the “name” option. You may add other options as desired.
7. Set up DNS
If you are using DNS servers supplied by your ISP, edit the file
/etc/resolv.conf by adding the following lines of code:
nameserver ip_addr_of_first_dns_server
nameserver ip_addr_of_second_dns_server
For example:
nameserver 168.95.1.1
nameserver 139.175.10.20
8. Use the following command to create a PPPoE connection:
pppd eth0
The eth0 is what is connected to the ADSL modem LAN port. The example above uses LAN1. To use LAN2,
type:
pppd eth1
9. Type ifconfig ppp0 to check if the connection is OK or has failed. If the connection is OK, you will see
information about the ppp0 setting for the IP address. Use ping to test the IP.
10. If you want to disconnect it, use the kill command to kill the pppd process.
