.TH HOSTADDR 1
.SH NAME
hostaddr \- show ethernet address, IP address or hostname
.SH SYNOPSIS
.B hostaddr
.RB [ \-eiah ]
.RB [ \-E
.IR eth-device ]
.RB [ \-I
.IR ip-device ]
.SH DESCRIPTION
Without any of the
.B \-eia
options,
.B hostaddr
shows the ethernet address, IP address and hostname of the local host on one
line in the given order. With options only the wanted fields are shown,
still in the same order, not in option order.
.SH OPTIONS
.TP
.B \-e
Show the ethernet address.
.TP
.B \-i
Show the IP address.
.TP
.B \-a
Show the fully qualified hostname. The IP address is shown if it
can't be translated to a host name. This usually indicates that the
DNS reverse address translation tables are incomplete or that
the name daemon couldn't be contacted.
.TP
.B \-h
Set the hostname of the machine if the caller is the superuser. (Used at
boot time by the network initialization scripts.)
.SH "SEE ALSO"
.BR ifconfig (8),
.BR dhcpd (8),
.BR nonamed (8),
.BR inet (8),
.BR boot (8).
