NAME
pppx
, pppac
— PPP multiplexer
device
SYNOPSIS
pseudo-device pppx
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/pipex.h>
DESCRIPTION
Thepppx
and pppac
drivers works
with the npppd(8) daemon to provide network interfaces for Point-to-Point
Protocol (PPP) sessions by request from the daemon.
pppx
operates by allocating a network interface for
each PPP session. pppac
concentrates multiple PPP
sessions on a single network interface. The interfaces also work with
pipex(4) to
accelerate the performance of data packet forwarding, and supports ioctls
which are added by pipex(4).
To use pppx
or
pppac
from
npppd(8) the
administrator needs to configure the interface configuration in
npppd.conf(5). Also the administrator needs to enable
pipex(4) by
setting net.pipex.enable to ‘1’ using
sysctl(8).

HISTORY
The pppx
driver first appeared in
OpenBSD 5.3. The pppac
interface driver first appeared in OpenBSD 6.7.
