pppoe-server - user-space PPPoE server
pppoe-server [options]
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.
-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.
-C ac_name
Specifies which name to report as the access concentrator name.
If not supplied, the host name is used.
-m MSS This option is passed directly to pppoe; see pppoe(8) for
details.
-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.
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:
nodetach noaccomp nobsdcom nodeflate nopcomp novj novjccomp
default-asyncmap
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.
