Binary package “libdnet” in ubuntu precise
DECnet Libraries
This package contains the libraries necessary for a functioning DECnet
system. Most DECnet programs require these libraries to be present on
the system. The libraries are:
libdnet - the basic DECnet API as featured on Ultrix(R) systems
libdnet_daemon - useful calls for writing DECnet daemons
libdap - DAP (Data Access Protocol) C++ classes
librms - High level library for programmatic access VMS files
.
If you're looking for libdnet, the "dumb" networking library from
libdnet.sf.net by Dug Song then you should install libdumbnet instead.
Sorry for any confusion caused!
