NAME

     hostaddr - show ethernet address, IP address or hostname


SYNOPSIS

     hostaddr [-eiah] [-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.

     -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 transla-
          tion  tables  are  incomplete  or  that the name daemon
          couldn't be contacted.

     -h   Set the hostname of the machine if the  caller  is  the
          superuser.  (Used at boot time by the network initiali-
          zation scripts.)
