Usage

Overview

The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP).

A ppp interface can be created at runtime using the ifconfig pppN create command or by setting up a hostname.if(5) configuration file for netstart(8).

The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped.
