SL(4) OpenBSD Programmer's Manual SL(4)NAME
sl - slip network interface
SYNOPSIS
pseudo-device sl
DESCRIPTION
The sl interface allows serial lines to be used as network interfaces
using the slip protocol.
An sl interface can be created at runtime using the ifconfig slN create
command or by setting up a hostname.if(5) configuration file for
netstart(8).
The following link-level options are configurable via ifconfig(8):
link0 Use Van Jacobsen TCP header compression.
link1 Suppress ICMP traffic.
link2 Auto-enable Van Jacobsen TCP header compression (enabled by
default).
DIAGNOSTICS
sl%d: af%d not supported. The interface was handed a message with
addresses formatted in an unsuitable address family; the packet was
dropped.
