.TH IFCONFIG 8
.SH NAME
ifconfig \- configure a TCP/IP device
.SH SYNOPSIS
.B ifconfig
.RB [ \-I
.IR ip-device ]
.RB [ \-h
.IR ipaddr ]
.RB [ \-n
.IR netmask ]
.RB [ \-iv ]
.SH DESCRIPTION
.B Ifconfig
initializes a TCP/IP device setting the IP address and/or netmask.  It will
report the address and netmask set.  This command may be used if the system
has not been configured properly yet.  It is only used at boot time to set a
fixed address for a system without a physical ethernet.  Normally the
.B inet
task will find it out by itself from the RARP server.
.SH OPTIONS
.TP
.B \-h
The decimal TCP/IP address to set.
.TP
.B \-n
The netmask to set.
.TP
.B \-i
Don't set the IP address or netmask if already set.  This way ifconfig cannot
interfere if the numbers have been found out by RARP.
.TP
.B \-v
Report IP address and netmask.  This is the default action if there are no
other options.
