Can somebody explain to me what PPPoE is?

[InlineFive]

I am wondering because if it has potential I am going to implement it for wireless security.

PPP over Ethernet (short: PPPoE) implementation a method for establishing PPP connections through Ethernet adapters is described in RFC 2516.

Functional Solution: DSL PPPOE and Cable/DSL Routers.

Softeare Solution: RASPPPOE, PPP over Ethernet Protocol for Windows 98/98SE/ME/2000/XP.

That's interesting, because there is a new piece of Linux software people like that's called RADIUS that uses PPPoE to authenticate wireless network users. Otherwise it blocks them. Mind you need a compatible router but those are cheap (D-Link 900AP+ mainly).

Radius (actually RADIUS, it's an acronym) has been around for a very long time (years).

I believe it would handle the PPPoE request like any other PPP authentication / authorization (used to be all dial-up).

RADIUS can also authenticate against certificates, LDAP compliant databases (like MS AD, Novel NDS, Open LDAP, etc), Locally administered user names (in the RADIUS config file), MD5, MAC addresses, token cards, etc. It is also used for 802.1x, EAP, etc. for wireless authentication and authorization.

I use freeRADIUS at home for Auth/Auth on my wireless and AAA for my Cisco practice rack.

The idea is to have a single (cluster for large organizations) auth/auth source for the network remote access systems. From there it also was used for 802.1x (port-based authentication / authorization .... if you don't pass RADIUS, you don't get into the switch and beyond) and wireless (username/password, MD5, Certificates, EAP, EAP-TLS, etc).

FWIW
