.RB [ \-m
.IR mtu ]

.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 \-m
The mtu to set.  (Minix-vmd only.)
.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.
.TP
.B \-a
Report the IP addresses and netmasks of all configured interfaces.
