pppx, pppac
— PPP multiplexer device
pseudo-device pppx
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/pipex.h>
The pppx 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).

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