PPPoE 서버 설치 및 구성

참 오래된 기술이다.

이런걸 정리해 놓은 게 있으려나..........있지.

간단히 국산블로그에서도

리눅스에 PPPoE 서버 구축하기


해외 블로그 에서도

간단히 옮겨보자꾸나.


1. Make sure you have an active internet connection. If not, set it up by using your favorite text editor (I use vim):

vim /etc/network/interfaces 
auto lo
iface lo inet loopback

iface eth0 inet static
address 89.xxx.yyy.zzz     #Your public IP address
netmask 255.255.255.240  #Your subnet mask
gateway 89.xxx.xxx.xxx    #Your gateway

iface eth1 inet static
address 192.168.1.254
netmask 255.255.255.0

Set up one or more nameservers (I use the free ones provided by Google):

echo "nameserver 8.8.8.8" > /etc/resolv.conf
echo "nameserver 8.8.4.4" >> /etc/resolv.conf

Ping some website to make sure your internet connection is working:

cristian@desktop:~$ ping google.com
PING google.com (209.85.229.147) 56(84) bytes of data.
64 bytes from ww-in-f147.1e100.net (209.85.229.147): icmp_req=1 ttl=52 time=83.0 ms

2. Install ppp daemon:

sudo apt-get install ppp

3. Now get rp-pppoe from here.

wget http://www.roaringpenguin.com/files/download/rp-pppoe-3.10.tar.gz

And extract it

 tar -zxvf  rp-pppoe-3.10.tar.gz

Now compile it

cd rp-pppoe-3.10/src/
./configure
make && make install

4. Now, we shall edit the PPPoE server options:

vim /etc/ppp/pppoe-server-options
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 8.8.8.8
ms-dns 8.8.4.4
netmask 255.255.255.0
defaultroute
noipdefault
usepeerdns

5. Add usernames and passwords:

vim /etc/ppp/chap-secrets

# Secrets for authentication using CHAP # client server secret IP addresses #USERNAME SERVER PASSWORD CLIENT IP ADDRESS "사용자이름" * "비밀번호" 192.168.1.1

6. Set up the IP addresses pool:

echo "192.168.1.1-20" > /etc/ppp/allip

This will assign the future clients one IP address from the 192.168.1.1 until 192.168.1.20 range.

7. Start the PPPoE server:

pppoe-server -C isp -L 192.168.1.254 -p /etc/ppp/allip -I eth1

8. Enable packet forwarding between network interfaces:

echo 1 > /proc/sys/net/ipv4/ip_forward

9. Set up NAT in order to provide internet access to the LAN computers:

iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE

클라이언트 구성 및 설명은 위에 언급한 한글 사이트에서


타깃 보드에 연결 설정을 합니다.

 

 # cat > tee /etc/ppp/options << "EOF"
 plugin rp-pppoe.so
 eth0
 defaultroute
 usepeerdns
 user "test"
 noauth
 noipdefault
 hide-password
 debug
 EOF

 

 # cat << "EOF" | tee -a /etc/ppp/chap-secrets > /dev/null 2>&1
 "test" * "test" *
 EOF

 

다음과 같이 ppp 데몬을 실행하면 접속이 된 것을 확인하실 수 있습니다.
