.Dd $Mdocdate: September 14 2015 $ .Dt PPPX 4 .Os .Sh NAME .Nm pppx , .Nm pppac .Nd PPP multiplexer device .Sh SYNOPSIS .Cd "pseudo-device pppx"
p n sys/socket.h n sys/ioctl.h n net/pipex.h .Sh DESCRIPTION The .Nm pppx and .Nm pppac drivers works with the .Xr npppd 8 daemon to provide network interfaces for Point-to-Point Protocol (PPP) sessions by request from the daemon. .Nm pppx operates by allocating a network interface for each PPP session. .Nm pppac concentrates multiple PPP sessions on a single network interface. The interfaces also work with .Xr pipex 4 to accelerate the performance of data packet forwarding, and supports ioctls which are added by .Xr pipex 4 .
p To use .Nm pppx or .Nm pppac from .Xr npppd 8 the administrator needs to configure the interface configuration in .Xr npppd.conf 5 . Also the administrator needs to enable .Xr pipex 4 by setting .Va net.pipex.enable to .Sq 1 using .Xr sysctl 8 . .Sh SEE ALSO .Xr inet 4 , .Xr inet6 4 , .Xr pipex 4 , .Xr hostname.if 5 , .Xr npppd.conf 5 , .Xr netstart 8 , .Xr npppd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm pppx driver first appeared in .Ox 5.3 . The .Nm pppac interface driver first appeared in .Ox 6.7 . .Sh AUTHORS .An David Gwynne Aq Mt dlg@openbsd.org .An Claudio Jeker Aq Mt claudio@openbsd.org
