hostaddr

HOSTADDR(1)						      General Commands Manual						       HOSTADDR(1)

NAME

       hostaddr - show ethernet address, IP address or hostname

SYNOPSIS

       hostaddr [-eia] [-E eth-device] [-I ip-device]

DESCRIPTION

       Without	any  of  the -eia options, 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.

OPTIONS

       -e     Show the ethernet address.

       -i     Show the IP address.  This will not work if no IP address has been found by RARP or by setting it with ifconfig(8).

       -a     Show the fully qualified hostname.  The IP address is shown again if it can't be translated to a host name.  (This usually indicates
	      that the DNS reverse address translation tables are incomplete.)

SEE ALSO

       ifconfig(8), rarpd(8), nonamed(8), set_net_default(8), boot(8).

DIAGNOSTICS

       "Timeout"
       Hostaddr  timed	out trying to get the IP address.  This means that the network connection is out of order or that the setup of the machine
       is bad.
