PPPOE-DISCOVERY(8) System Manager's Manual PPPOE-DISCOVERY(8)
pppoe-discovery - perform PPPoE discovery
pppoe-discovery [ options ]
pppoe-discovery { -V | -h }
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.
-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. This
option is mandatory.
-D file_name
The -D option causes every packet to be dumped to the
specified file_name. This is intended for debugging only.
-U
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 match.
-A
This option is accepted for compatibility with pppoe, but
has no effect.
-V | -h
Either of these options causes pppoe-discovery to print
its version number and usage information, then exit.
pppoe-discovery was written by Marco d'Itri <md@linux.it>, based
on pppoe by Dianne Skoll <dianne@skoll.ca>.
