Hello,

When running OpenSSH server under cygwin on a windows machine,
does each SSH connection require a buying CAL (client access license) 
from microsoft?

More concretely,
If I have a "Windows 10 Home" and I run Cygwin + OpenSSH server,
can multiple users connect and run programs at the same time?
(of course they technically can, but is it legally allowed?).

This assumes the users only run Cygwin programs, never any windows 
programs, and not any RDS connections or GUI applications (not even X11).


Sorry if this is slightly off-topic for the technical list,
but I can't find any reliable information regarding this question.

The only somewhat-related post I've managed to found is this one
from 1999 about running Samba on Windows NT, saying:

     If we overcome this, Samba will work on NT. I have done a research
     on the legal/license implications of this, and look very
     interesting:
        * The legal limit of 10 connections to an NT workstation
          dissapear => NT server value for NT workstation price, legal.
        * No need for CAL (client access license) to connect to an NT
          box => legal non Win clients, and the NT Terminal server client
          implications seem interesting too.
     (from http://www.cygwin.com/ml/cygwin/1999-09/msg00046.html )

Is running OpenSSH server considered the same as running samba?

Any feedback is appreciated.

Thanks,
  - Assaf Gordon
