Prepare all information needed: username, password and server IP Address (public) up to existing PPPoE configuration.
User : [email protected] Password : bbb Service : packageservice IP Address : yyy.yyy.yyy.yyy Local IP Address: eth1 -> local, for example: 192.168.0.254/24 eth0 -> wan, for example: yyy.yyy.yyy.yyy, not need to configure, because it will update automatically using PPPoE
Commands for PPPoE Setup:
$ sudo pppoe-setup
It will prompt you about configuration of PPPoE client that you want to use.
USERNAME >>> Enter your PPPoE user name (default username): [email protected]
Fill with username and password that already prepared.
INTERFACE >>> Enter the Ethernet interface connected to the DSL modem For Solaris, this is likely to be something like /dev/hme0. For Linux, it will be ethn, where ‘n’ is a number. (default eth0): eth0
Fill with interface where PPPoE will dial to its server (toward WAN).
>>> enter the demand value (default no): (tekan enter)
For dedicated connection, at option “demand value” choose “no”
Please enter the IP address of your ISP’s primary DNS server. If your ISP claims that ‘the server will provide DNS addresses’, enter ‘server’ (all lower-case) here. If you just press enter, I will assume you know what you are doing and not modify your DNS setup. >>> Enter the DNS information here: XXX.XXX.XXX.XXX >>> Enter the secondary DNS server address here: XXX.XXX.XXX.XXX
Fill with IP address of DNS 1 and DNS 2.
PASSWORD >>> Please enter your PPPoE password: yyyy
Enter password which will be used (twice with confirmation).
FIREWALLING Please choose the firewall rules to use. Note that these rules are very basic. You are strongly encouraged to use a more sophisticated firewall setup; however, these will provide basic security. If you are running any servers on your machine, you must choose ‘NONE’ and set up firewalling yourself. Otherwise, the firewall rules will deny access to all standard servers like Web, e-mail, ftp, etc. If you are using SSH, the rules will block outgoing SSH connections which allocate a privileged source port. The firewall choices are: 0 – NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine. You are STRONGLY recommended to use some kind of firewall rules. 1 – STANDALONE: Appropriate for a basic stand-alone web-surfing workstation 2 – MASQUERADE: Appropriate for a machine acting as an Internet gateway for a LAN >>> Choose a type of firewall (0-2): 0
With assumption that this firewall configuration (iptables) will use default configuration then choose 0.
>>> Accept these settings and adjust configuration files (y/n)? y
On last prompt, confirm that previous choices is right.
Then, you need to set up service name on pppoe.conf
# vim /etc/ppp/pppoe.conf
Search for line with “SERVICENAME”, then add it. Enter without quotes.
Run PPPoE client.
If there is no problem found, then there will such information like:
Finally, your Linux PPPoE client setup is succeeded.
Restart PPPoE Client on Linux
Below is a simple script which can be used to restart PPPoE client on Linux. FYI, Linux not shipped with built-in command to restart its PPPoE client.
#!/bin/bash if [ -r /var/run/ppp0.pid ]; then /usr/sbin/pppoe-stop && /usr/sbin/pppoe-start else echo "$0: No PPPoE connection appears to be running" echo "Trying to start PPPoE Connection" /usr/sbin/pppoe-start fi exit 0
The purpose of code above is to help administrator to restart PPPoE client without open new connection to remote host.
