NAME
pppoe-server - user-space PPPoE server
SYNOPSIS
pppoe-server [options]
DESCRIPTION
pppoe-server is a user-space server for PPPoE (Point-to-Point Protocol
over Ethernet) for Linux and other UNIX systems. pppoe-server works in
concert with the pppoe client to respond to PPPoE discovery packets
and set up PPPoE sessions.
OPTIONS
-F
The -F option causes pppoe-server not to fork and become a
daemon. The default is to fork and become a daemon.
-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-server, but should not be configured to have
an IP address. You can supply multiple -I options if you want the
server to respond on more than one interface.
-T timeout
This option is passed directly to pppoe; see pppoe(8) for
details. If you are using kernel-mode PPPoE, this option has no effect.
-C ac_name
Specifies which name to report as the access concentrator name. If not
supplied, the host name is used.
-S name
Offer a service named name. Multiple -S options may
be specified; each one causes the named service to be advertised
in a Service-Name tag in the PADO frame. The first -S option
specifies the default service, and is used if the PPPoE client
requests a Service-Name of length zero.
-m MSS
This option is passed directly to pppoe; see pppoe(8) for
details. If you are using kernel-mode PPPoE, this option has no effect.
-s
This option is passed directly to pppoe; see pppoe(8) for
details. In addition, it causes pppd to be invoked with the
sync option.
-L ip
Sets the local IP address. This is passed to spawned pppd processes.
If not specified, the default is 10.0.0.1.
-R ip
Sets the starting remote IP address. As sessions are established,
IP addresses are assigned starting from ip. pppoe-server
automatically keeps track of the pool of addresses and passes a
valid remote IP address to pppd. If not specified, a starting address
of 10.67.15.1 is used.
-N num
Allows at most num concurrent PPPoE sessions. If not specified,
the default is 64.
-p fname
Reads the specified file fname which is a text file consisting of
one IP address per line. These IP addresses will be assigned to clients.
The number of sessions allowed will equal the number of addresses found
in the file. The -p option overrides both -R and -N.
In addition to containing IP addresses, the pool file can contain lines
of the form:
a.b.c.d-e
which includes all IP addresses from a.b.c.d to a.b.c.e. For example,
the line:
1.2.3.4-7
is equivalent to:
1.2.3.4
1.2.3.5
1.2.3.6
1.2.3.7
-r
Tells the PPPoE server to randomly permute session numbers. Instead of
handing out sessions in order, the session numbers are assigned in an
unpredictable order.
-u
Tells the server to invoke pppd with the unit option. Note
that this option only works for pppd version 2.4.0 or newer.
-o offset
Instead of numbering PPPoE sessions starting at 1, they will be numbered
starting at offset+1. This allows you to run multiple servers on
a given machine; just make sure that their session numbers do not
overlap.
-f disc:sess
The -f option sets the Ethernet frame types for PPPoE discovery
and session frames. The types are specified as hexadecimal numbers
separated by a colon. Standard PPPoE uses frame types 8863:8864.
You should not use this option unless you are absolutely sure
the peer you are dealing with uses non-standard frame types.
-k
The -k option tells the server to use kernel-mode PPPoE on Linux.
This option is available only on Linux kernels 2.4.0 and later, and
only if the server was built with kernel-mode support.
-h
The -h option prints a brief usage message and exits.
OPERATION
pppoe-server listens for incoming PPPoE discovery packets. When
a session is established, it spawns a pppd process. The following
options are passed to pppd:
In addition, the local and remote IP address are set based on the
-L and -R options. The pty option is supplied along
with a pppoe command to initiate the PPPoE session. Finally,
additional pppd options can be placed in the file
/etc/ppp/pppoe-server-options (which must exist, even if it is just
empty!)
Note that pppoe-server is meant mainly for testing PPPoE clients.
It is not a high-performance server meant for production use.
