G'day Fellow Netlanders-- Lately there has been some discussion concerning the simultaneous use of Telnet/FTP and NFS on networked PC's. As the network administrator of a 90-node ethernet TCP/IP LAN, I am eager to make both services available to our users. To date I have been using NCSA Telnet (version 2.2D) and the consensus amongst our users is that they love it. I am now in search of an NFS program that they can also live with. As I understand the issue, there is a problem of maintaining control over the "IP stack" when two or more "application layer" programs attempt to simultaneously access the same ethernet card. Two commercial products that apparently integrated Telnet/FTP and NFS services are Sun's PC-NFS and Wollongong's WIN/TCP (are there others? see Q2 below). Some authors have implied that Sun's Telnet program leaves much to be desired. They therefore seek to use NCSA Telnet (version 2.2D/NFS-A) in conjunction with Sun's PC-NFS. I myself have just finished a week or so of setting up Wollongong's WIN/TCP on a handful of PC's connected to a Sun server (4/330 running SunOS 4.0.3). I have found that the NFS service runs great but that the Telnet program (using vt100 emulation) is very slow and possesses little potential for customization (e.g. screen colors; key bindings). I tried running NCSA Telnet 2.2D/NFS-A in conjunction with Wollongong's NFS module and received the error: NFS000F : PC-NFS is not installed or has been disabled. My guess is that NCSA Telnet 2.2D/NFS-A is designed for use with _Sun's_ PC-NFS. All of this had engendered a number of questions that I'm hoping the Network Gurus out there can answer: Q1: Does the term "PC-NFS" always mean "Sun PC-NFS" unless otherwise specified? Q2: What other commercial packages are available (besides Wollongong and Sun) that integrate Telnet/FTP and NFS? Are they any good? Q3: Is Sun's Telnet program really all that bad? Does it allow customization of screen colors and/or key bindings? How is its scroll rate? Q4: Hats off to the makers of NCSA Telnet/FTP. Dare I ask, are there plans to develop a companion NFS program to complement it? Or does one already exist? Many thanks for any responses. I'll be happy to post a summary of the results.

Quoth patrick@casbs.Stanford.EDU (Patrick Goebel) (in <1991Feb11.222828.1566@portia.Stanford.EDU>): #Q1: Does the term "PC-NFS" always mean "Sun PC-NFS" unless otherwise #specified? Well, usage tends to be somewhat lax, but since PC-NFS is a registered trademark of Sun Microsystems it _should_ always refer to our product. The X/Open terminology for a generic DOS NFS implementation is (PC)NFS..... #Q2: What other commercial packages are available (besides Wollongong #and Sun) that integrate Telnet/FTP and NFS? Are they any good? FTP Software, Beame & Whiteside, Siemens Nixdorf (or is it Nixdorf Siemens?) I'll leave ratings up to more objective folks. #Q3: Is Sun's Telnet program really all that bad? Does it allow #customization of screen colors and/or key bindings? How is its scroll #rate? It's basic. Very basic. There are a number of third-party products which offer multi-emulation, multi-session, multi-feature terminal emulation, and so far we have elected not to compete with them. #Q4: Hats off to the makers of NCSA Telnet/FTP. Dare I ask, are there #plans to develop a companion NFS program to complement it? Or does #one already exist? Can't speak for the various NCSA developers, but I should point out that developing a bulletproof DOS redirector is a much more thorny task than building an application such as Telnet.
