pppoe-discovery - perform PPPoE discovery
performs the same discovery process as pppoe
does not initiate a session. It sends a PADI packet and then prints the names
of access concentrators in each PADO packet it receives.
- -I interface
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. The default interface
- -D file_name
The -D option causes every packet to be
dumped to the specified file_name. This is intended for debugging
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.
- -S service_name
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.
- -C ac_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
This option is accepted for compatibility with
pppoe, but has no effect.
- -V | -h
Either of these options causes
