setether - Set the ethernet address for use with DECnet
setether <if> [<if>...]|all
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.
set the MAC address of eth0.
# /sbin/setether eth0
set the MAC address of all ethernet interfaces
# /sbin/setether all
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
match the one in /etc/decnet.conf(5).
