On this basis, I configured a mount on the Linux machine of the Windows share using cifs/smb. fstab entry thus: //WINDOWS-IP/WINDOWS-SHARE-NAME LINUX-MOUNT-DIR cifs credentials=CREDS-FOR-WINDOWS-STORED-IN-LINUX,rw,uid=1000,gid=1000,file_mode=0755,dir_mode=0755 0 0 (where 1000 is the UID and GID of my Linux user) Then I used the normal tramp /ssh:... form to open LINUX-MOUNT-DIR and then open a file contained on the mount. I.e. With emacs running on macOS, this is going macOS -> (ssh) -> Linux -> (smb) -> Windows. And it seems to work just as you'd hope. So this seems to be an option for the use case of access via an SSH proxy, provided the user has admin rights on the proxy (the Linux machine in this case) to install on the proxy a CIFS mount of the Windows share. > > > From an emacs perspective, it seems a shame not to be able to use ssh, > > given that modern Windows commonly supports ssh and provides a bash > > shell.

Instead, emacs will go to a time out trying to access the Windows machine via the ssh proxy. I don't know what's changed. In any case, I am enclosing the debug output file. It is 86MB, so I am sharing via Google Drive, hopefully that's OK. https://drive.google.com/file/d/1aH1c-58rfOmjKVBqqfJ9QpzY5m-ltmDQ/view?usp=sharing This is with the Windows machine using /usr/bin/sh as the default shell for ssh login. Confirmed at the client command prompt - if I do "ssh WINDOWS", I log in and get the "sh" prompt. > > > Best > > -DG > > Best regards, Michael. > -- NOTICE: This email and its attachments may contain privileged and confidential information, only for the viewing and use of the intended recipient.
