pppoe-sniff
PPPOE-SNIFF(8) System Manager's Manual PPPOE-SNIFF(8)
NAME
pppoe-sniff - examine network for non-standard PPPoE frames
SYNOPSIS
pppoe-sniff [options]
DESCRIPTION
pppoe-sniff listens for likely-looking PPPoE PADR and session frames and deduces extra options required for pppoe(8) to work.
Some DSL providers seem to use non-standard frame types for PPPoE frames, and/or require a certain value in the Service-Name field. It is
often easier to sniff those values from a machine which can successfully connect rather than try to pry them out of the DSL provider.
To use pppoe-sniff, you need two computers, a DSL modem and an Ethernet hub (not an Ethernet switch.)
If the DSL modem normally connects directly to your computer's Ethernet card, connect it to the "uplink" port on the Ethernet hub. Plug
two computers into normal ports on the hub. On one computer, run whatever software the DSL provider gave you on whatever operating system
the DSL provider supports. On the other computer, run Linux and log in as root.
On the Linux machine, put the Ethernet interface into promiscuous mode and start pppoe-sniff. If the ethernet interface is eth0, for exam-
ple, type these commands:
ifconfig eth0 promisc
pppoe-sniff -I eth0
On the other machine, start your DSL connection as usual. After a short time, pppoe-sniff should print recommendations for the value of
PPPOE_EXTRA. Set this value in /etc/ppp/pppoe.conf. If pppoe-sniff indicates that something special is required in PPPOE_EXTRA, please e-
mail this to pppoe@roaringpenguin.com along with the name of your ISP and the manufacturer and model number of your DSL modem. This infor-
mation will be collated and provided on the PPPoE web page for users who do not have two computers.
After pppoe-sniff finishes (or you stop it if it seems hung), remember to turn off promiscuous mode:
ifconfig eth0 -promisc
OPTIONS
-I interface
The -I option specifies the Ethernet interface to use. Under Linux, it is typically eth0 or eth1. The interface should be "up" and
in promiscuous mode before you start pppoe-sniff.
-V The -V option causes pppoe-sniff to print its version number and exit.
BUGS
pppoe-sniff only works on Linux.
