There are a number of potential advantages of ARPA FTP, as Jon pointed out: - Many implementations support resumptions - Spooled implementations are available - the single channel makes gatewaying rather easier A copy of the protocol can be obtained from: ITSU Department of Trade and industry Kingsgate House 66-74 Victoria Street London SW1 The protocol will operate over TCP/IP, and has assigned sockets: 47 (straight NIFTP) 61 (NIFTP + JNT Mail) There are implementations for a wide range of machines. A full table of colured book implementations for the various machine ranages can be obtained from Dr. Bob Cooper who runs the Joint Network Team. A brief note on UNIX implementations, which I know are of particular interest. There is a JNT supported implemetnation, which is available through Spider Systems. Contact Andy Davis . However, this does not support either TCP or resumptions. There is another UNIX implementation, which is not supported but is being assembled as a public domain package by Cambridge/UCL/Nottingham. This is a very full implementation of the protocol, and has TCP/IP (4.2/4.3). We believe that this system is substantially better than the official one, but of course there is no support. We are currently doing testing as a smallish group, but the system will be distributed in due course, after it has been released to a number of beta sites. If anyone is interested, contact . Do NOT send messages to mailgroup@cs.ucl.ac.uk, as suggested by Jon. Steve
