FreeBSD has minimal support for it in the Token Ring package being developed in FreeBSD-CURRENT. Early UNIX machines had a primitive kind of networking called UUCP for UNIX to UNIX Copy. It ran over dialup phone lines or dedicated serial connections. System V still calls this system Basic Networking Utilities or BNU. Despite its primitiveness and despite the Internet there are still some applications where UUCP makes sense but this book discusses it no further. The Internet Protocols were developed by the US Defense Advanced Research Projects Agency DARPA for its ARPANET network. The software was originally developed in the early 80s by BBN and the CSRG at the University of California at Berkeley. The first widespread release was with the operating system the v 2003 04 02 06 48 55 277 2 April 2003 17 00 47 The Complete FreeBSD . tools page 278 The Complete FreeBSD 278 granddaddy of FreeBSD. After the introduction of IP the ARPANET gradually changed its name to Internet. The Internet Protocol is usually abbreviated .
