NAME

6       pppoe-discovery - perform PPPoE discovery
7

SYNOPSIS

9       pppoe-discovery [ options ]
10       pppoe-discovery { -V | -h }
11

DESCRIPTION

13       pppoe-discovery  performs the same discovery process as pppoe, but does
14       not initiate a session.  It sends a PADI packet  and  then  prints  the
15       names of access concentrators in each PADO packet it receives.
16

OPTIONS

18       -I interface
19              The  -I  option  specifies the Ethernet interface to use.  Under
20              Linux, it is typically eth0 or eth1.  The  interface  should  be
21              “up” before you start pppoe-discovery, but should not be config‐
22              ured to have an IP address.  The default interface is eth0.
23
24       -D file_name
25              The -D option causes every packet to be dumped to the  specified
26              file_name.  This is intended for debugging only.
27
28       -U
29              Causes pppoe-discovery to use the Host-Uniq tag in its discovery
30              packets.  This lets you run multiple instances of  pppoe-discov‐
31              ery  and/or  pppoe without having their discovery packets inter‐
32              fere with one another.  You  must  supply  this  option  to  all
33              instances that you intend to run simultaneously.
34
35       -S service_name
36              Specifies  the  desired service name.  pppoe-discovery will only
37              accept access concentrators which can provide the specified ser‐
38              vice.   In  most cases, you should not specify this option.  Use
39              it only if you know that there are multiple access concentrators
40              or know that you need a specific service name.
41
42       -C ac_name
43              Specifies the desired access concentrator name.  pppoe-discovery
44              will only accept the specified  access  concentrator.   In  most
45              cases,  you  should not specify this option.  Use it only if you
46              know that there are multiple access concentrators.  If both  the
47              -S and -C options are specified, they must both match.
48
49       -A
50              This option is accepted for compatibility with pppoe, but has no
51              effect.
52
53       -V | -h
54              Either of these options causes pppoe-discovery to print its ver‐
55              sion number and usage information, then exit.
