What application do you use to create SSH service over MS Windows platform?
There are good free alternatives?
I would use OpenSSH: winscp.net/.../guide_windows_openssh_server
take a look at MobaXterm. I use it as a replacement for putty but it has ssh server too.
may be more than you need though.
Depends on which version of Windows. If Windows 10 (possibly even the upcoming Windows Server 2016) then Powershell has support for an SSH server (using Posh-SSH I believe), earlier versions of windows you would have to install something like OpenSSH.
Thanks everybody. We are using http://www.kpym.com/ as a TTY server, good enough and "free". But this tool is no longer updated and I don´t know how long it will be available or run on new MS platform.
Check out MobaXterm. it has ssh server and client and a variety of other good stuff.
