-Here are a few quick points about DECnet support...
-
- o iproute2 is the tool of choice for configuring the DECnet support for
- Linux. For many features, it is the only tool which can be used to
- configure them.
-
- o No name resolution is available as yet, all addresses must be
- entered numerically.
-
- o Remember to set the hardware address of the interface using:
-
- ip link set ethX address xx:xx:xx:xx:xx:xx
- (where xx:xx:xx:xx:xx:xx is the MAC address for your DECnet node
- address)
-
- if your Ethernet card won't listen to more than one unicast
- mac address at once. If the Linux DECnet stack doesn't talk to
- any other DECnet nodes, then check this with tcpdump and if its
- a problem, change the mac address (but do this _before_ starting
- any other network protocol on the interface)
-
- o Whilst you can use ip addr add to add more than one DECnet address to an
- interface, don't expect addresses which are not the same as the
- kernels node address to work properly with 2.4 kernels. This should
- be fine with 2.6 kernels as the routing code has been extensively
- modified and improved.
-
- o The DECnet support is currently self contained. It does not depend on
- the libdnet library.
