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).
