It provides reliable stream and sequenced 10*4882a593Smuzhiyun packet communications over which run a variety of services similar 11*4882a593Smuzhiyun to those which run over TCP/IP. 12*4882a593Smuzhiyun 13*4882a593Smuzhiyun To find some tools to use with the kernel layer support, please 14*4882a593Smuzhiyun look at Patrick Caulfield's web site: 15*4882a593Smuzhiyun <http://linux-decnet.sourceforge.net/>. 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun More detailed documentation is available in 18*4882a593Smuzhiyun <file:Documentation/networking/decnet.rst>. 19*4882a593Smuzhiyun 20*4882a593Smuzhiyun Be sure to say Y to "/proc file system support" and "Sysctl support" 21*4882a593Smuzhiyun below when using DECnet, since you will need sysctl support to aid 22*4882a593Smuzhiyun in configuration at run time. 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun The DECnet code is also available as a module ( = code which can be 25*4882a593Smuzhiyun inserted in and removed from the running kernel whenever you want). 26*4882a593Smuzhiyun The module is called decnet. 27*4882a593Smuzhiyun 28*4882a593Smuzhiyunconfig DECNET_ROUTER 29*4882a593Smuzhiyun bool "DECnet: router support" 30*4882a593Smuzhiyun depends on DECNET 31*4882a593Smuzhiyun select FIB_RULES 32*4882a593Smuzhiyun help 33*4882a593Smuzhiyun Add support for turning your DECnet Endnode into a level 1 or 2 34*4882a593Smuzhiyun router. This is an experimental, but functional option. If you 35*4882a593Smuzhiyun do say Y here, then make sure that you also say Y to "Kernel/User 36*4882a593Smuzhiyun network link driver", "Routing messages" and "Network packet 37*4882a593Smuzhiyun filtering". The first two are required to allow configuration via 38*4882a593Smuzhiyun rtnetlink (you will need Alexey Kuznetsov's iproute2 package 39*4882a593Smuzhiyun from <ftp://ftp.tux.org/pub/net/ip-routing/>). The "Network packet 40*4882a593Smuzhiyun filtering" option will be required for the forthcoming routing daemon 41*4882a593Smuzhiyun to work. 42*4882a593Smuzhiyun 43*4882a593Smuzhiyun See <file:Documentation/networking/decnet.rst> for more information. 44
