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 Jacobson TCP header compression.
- link1
- Suppress ICMP traffic.
- link2
- Auto-enable Van Jacobson TCP header compression (enabled by default).
DIAGNOSTICS
- sl0: afX not supported.
- The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped.
