NAME

       setether - Set the ethernet address for use with DECnet

SYNOPSIS

       setether <if> [<if>...]|all [options]

DESCRIPTION

       Set ethernet MAC address on ethernet adaptors

       This script should be run at system startup. It will change the ethernet hardware (MAC) address of any or
       all ethernet interfaces to match the DECnet node address. DECnet requires that the  MAC  address  of  all
       ethernet  adaptors  running  the  protocol be set approriately.  If you do not run setether then you must
       change the ethernet address in some other way for DECnet to work.
       By default no ethernet interfaces will have their MAC addresses changed by setether, if you  specify  all
       then  all  interfaces  name  eth*  will be changed, otherwise a list of interface names can be specified.
       setether will enable (UP) all interfaces it changes the MAC addresses of.
       (2.4 only) The first interface specified on the command-line will also be made the default interface  for
       DECnet  operations  (ie  attempts  to  contact  nodes  not  in the neighbour table will be done over this
       interface).
       This script must be run with the interface inactive, it is normally run  from  /etc/init.d/decnet  before
       TCP/IP starts up.

EXAMPLES

       set the MAC address of eth0.

           # /sbin/setether eth0

       set the MAC address of all ethernet interfaces

           # /sbin/setether all

HELPFUL HINTS

       If  you  have  multiple  ethernet cards on your system and they are connected to the the same network you
       should specify which one you want to use for DECnet communication on the setether command line, otherwise
       they will both be given the same MAC address and this is probably not what you want.
       Running  DECnet  on multiple ethernet interfaces only works under Linux 2.4. If you are running Linux 2.2
       then the interface name on the setether command line must match the one in /etc/decnet.conf(5).
