What is the likelihood of Microsoft phasing out a protocol they invented (SMB) in favor of one they id not (NFS)?

But how do you do this in Windows 10? All supported desktop and server releases of Microsoft Windows include NFS support. See here for the Windows 7 and Windows Server 2008 R2 instructions, for example: https://technet.microsoft.com/en-us/library/cc732891(v=ws.11).aspx Starting Client for NFS - technet.microsoft.com<https://technet.microsoft.com/en-us/library/cc732891(v=ws.11).aspx> technet.microsoft.com To start Client for NFS from the Windows interface Open Services for Network File System: click Start, point to Programs or All Programs, point to Administrative ... macOS, IBM i, Linux, and all UNIX variants that I can think of also include NFS support. It's quite a popular protocol, more popular than SMB/CIFS. There's even a free NFS client for PC-DOS/MS-DOS/FreeDOS/DR-DOS operating systems (would you believe): http://freedos.sourceforge.net/wiki/index.php/NFS It's probably past time to phase out the SMB protocol given recent vulnerabilities and attacks such as WannaCry and ExPetr that affected Windows systems. And if you decide to use file sharing of any sort, please adopt and maintain security best practices if you haven't already. Going forward, if you absolutely must have SMB protocol connectivity, then "leapfrogging" is technically possible, I believe. The best leapfrogging approach would be to configure Linux on Z such that z/OS connects via NFS to Linux, thence Linux (using Samba) connects via SMB. In other words, Linux on Z acts as a file/directory resharing gateway. I don't recommend leapfrogging, but technically it should work. Variations are possible with zdsfs instead of NFS for certain use cases. >Does NFS seamlessly connect z/OS to z/OS Classic data sets >(e.g. PDSE to ISPF LM services)? Yes, if I understand your "e.g." correctly. Here's the z/OS 2.2 NFS Guide and Reference (direct link, subject to change) if you'd like the full details: http://publibz.boulder.ibm.com/epubs/pdf/cpn2co11.pdf To future readers: if this link is broken or not applicable (because you're running a newer z/OS release for example), try searching for IBM Publication SC23-6883 (latest revision), or check the z/OS part of the IBM Knowledge Center. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
