0007 help
0008 The DECnet networking protocol was used in many products made by
0009 Digital (now Compaq). It provides reliable stream and sequenced
0010 packet communications over which run a variety of services similar
0011 to those which run over TCP/IP.
0012
0013 To find some tools to use with the kernel layer support, please
0014 look at Patrick Caulfield's web site:
0015 <http://linux-decnet.sourceforge.net/>.
0016
0017 More detailed documentation is available in
0018 <file:Documentation/networking/decnet.rst>.
0019
0020 Be sure to say Y to "/proc file system support" and "Sysctl support"
0021 below when using DECnet, since you will need sysctl support to aid
0022 in configuration at run time.
0023
0024 The DECnet code is also available as a module ( = code which can be
0025 inserted in and removed from the running kernel whenever you want).
0026 The module is called decnet.

0033 Add support for turning your DECnet Endnode into a level 1 or 2
0034 router. This is an experimental, but functional option. If you
0035 do say Y here, then make sure that you also say Y to "Kernel/User
0036 network link driver", "Routing messages" and "Network packet
0037 filtering". The first two are required to allow configuration via
0038 rtnetlink (you will need Alexey Kuznetsov's iproute2 package
0039 from <ftp://ftp.tux.org/pub/net/ip-routing/>). The "Network packet
0040 filtering" option will be required for the forthcoming routing daemon
0041 to work.
