== The Basics ==
You can use a Linux box in place of a PPPoE-capable router. Why would you want to do this?
* You're already running a Linux box, and you don't see any point in powering a router as well
* You want fine control over packets
* You have a PPPoE router but it doesn't do everything you want
== Debian/squeeze ==
This is what RogerBW is using. It'll probably be much the same on other Linuxen. The basic recipe came from [http://www.aa-asterisk.org.uk/index.php/Connecting_to_AAISP_using_PPPoE].
You will have two ethernet interfaces - one for your internal network (let's assume that's eth1), one for connection to the BT modem (eth0). You will be running PPPoE over the external interface, creating a new interface that actually passes packets.
=== Setup ===
* Install ppp, pppoe and iproute.
* Edit /etc/ppp/peers/aaisp to include:
user email@example.com <----- your AAISP login
eth0 <----- The ethernet interface to run PPPoE on
#usepeerdns <----- uncomment this if you want resolv.conf to be set up automatically
lcp-echo-interval 1 <---- this is how often the LCP echo packets get sent to AAISP, in seconds.
lcp-echo-failure 10 <---- this is how many LCP echo failures before the ppp daemon quits
maxfail 0 <---- redial forever until your modem regains sync else default is 10x or N times if you enter N
#holdoff 120 <---- this will cause pppd to dial once every 2 mins else default is 0 sec
* Edit /etc/ppp/chap-secrets to include this line, consisting of three tab-separated words. The first entry is your AAISP router login, the second is an asterisk, and the third is your AAISP router password. For example:
firstname.lastname@example.org * pa$$w0rd
* Create /etc/ppp/ipv6-up.d/0000defaultroute. In it place the following shell script:
/sbin/ip -6 route add default dev $1
* chmod it 755.
=== Testing ===
Run as root: pppoe -A
This should show something like this:
Got a cookie: 6e c5 4a dd 1e c0 d6 b6 fe b4 4b 23 38 8f 63 58
To start your PPPoE session just type
and to stop it running
You can check connectivity with a cron job, and add a stanza to /etc/network/interfaces to connect at boot.
