PPPOE-DISCOVERY(8)                                                                                            PPPOE-DISCOVERY(8)



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
       -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 is eth0.

       -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  concentra-
              tor.   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.
