pppoe-server 命令

常用示例

说明

pppoe-server implements a PPPoE access concentrator that accepts incoming PPPoE client (PADI/PADR) frames on a specified Ethernet interface. For each accepted session it spawns a pppd instance plumbed to the user-space pppoe plugin (or the in-kernel driver with -k) and assigns a remote IP from the local pool unless -D delegates that to pppd. Typical deployments run pppoe-server as part of a small lab DSL/PPPoE setup; ISPs more commonly use it as the front end to a RADIUS-backed AAA stack via pppd's radius plugin.

参数

-I _INTERFACE_

Ethernet interface to listen on. Repeatable to serve multiple interfaces.

-L _IP_

Local (server-side) IP address (default 10.0.0.1).

-R _IP_

Remote IP pool starting address (default 10.67.15.1); each session gets the next address.

-p _FILE_

Read the remote IP pool from a text file (one address per line).

-S _NAME_

Advertised service name. Repeatable to advertise multiple services.

-C _AC_NAME_

Access-concentrator name announced in PADO replies (default: hostname).

-N _NUM_

Maximum concurrent sessions (default 64).

-x _N_

Limit concurrent sessions from a single peer MAC.

-O _FILE_

Path to a pppd options file used for every spawned session.

-T _SECONDS_

Idle timeout passed through to pppoe.

-m _MSS_

Clamp the negotiated TCP MSS to _MSS_.

-D

Delegate IP address assignment to pppd (do not allocate from the local pool).

-k

Use the in-kernel PPPoE driver (Linux 2.4+).

-F

Run in the foreground rather than daemonising.

-X _PIDFILE_

Write the daemon PID to _PIDFILE_ with locking.

-q _PATH_

Path to the pppd binary.

-Q _PATH_

Path to the user-space pppoe binary.

-u

Invoke pppd with the unit option for predictable interface naming.

-i

Silently drop PADI broadcasts when no session slots remain.

-r

Randomise PPPoE session IDs.

-h

Print usage and exit.
