NAME¶
pppoe-discovery - perform PPPoE discovery
SYNOPSIS¶
pppoe-discovery [ options ]
pppoe-discovery { -V | -h }
DESCRIPTION¶
pppoe-discovery performs the same discovery process as pppoe, but does not initiate a session. It sends a PADI packet and then prints the names of access concentrators in each PADO packet it receives.
OPTIONS¶
The -I option specifies the Ethernet interface to
use. Under Linux, it is typically eth0 or eth1. The interface should be
“up” before you start pppoe-discovery, but should
not be configured to have an IP address. This option is
mandatory.
The -D option causes every packet to be dumped to
the specified file_name. This is intended for debugging only.
Causes pppoe-discovery to use the Host-Uniq tag in
its discovery packets. This lets you run multiple instances of
pppoe-discovery and/or pppoe without having their discovery
packets interfere with one another. You must supply this option to all
instances that you intend to run simultaneously.
Specifies the desired service name.
pppoe-discovery will only accept access concentrators which can provide
the specified service. In most cases, you should not specify this
option. Use it only if you know that there are multiple access concentrators
or know that you need a specific service name.
Specifies the desired access concentrator name.
pppoe-discovery will only accept the specified access concentrator. In
most cases, you should not specify this option. Use it only if you know
that there are multiple access concentrators. If both the -S and
-C options are specified, they must both match.
This option is accepted for compatibility with
pppoe, but has no effect.
Either of these options causes pppoe-discovery to
print its version number and usage information, then exit.
