At a high level, I can't think of any reason Cygwin's OpenSSH server couldn't be used as part of an HA setup. However, what you need to make it work is going to be very dependent on the specific HA setup you need, the hardware you're running on, the network and infrastructure requirements, and so forth. You're not going to find a simple guide to setting this up, because there are simply too many variables. If you have specific questions, you might be able to get practical help from the open source community, however things like working out what the requirements are, or whether they can be met with any given piece of software, is the sort of thing I would expect to pay for if I couldn't do it in-house.* I also do not think this mailing list is likely to be able to offer much practical support: this list is devoted to Cygwin, and therefore to the specifics of providing Cygwin's Linux-like environment and API on Windows systems. The complicated bits of setting up any HA environment are at best tangential to that aim. I think your starting point will need to be working out what you need for these specific HA services (a) on Windows and (b) using OpenSSH's SFTP server software, and coming back to this list for help only when you have specific questions about running OpenSSH in a Cygwin environment, and which you haven't been able to answer based on the Cygwin FAQ and documentation. HTH Adam * If you *want* to pay someone to help you with this, my day job for the past 13 years has been software engineering for high-reliability telecoms servers, including how to maintain HA SFTP service in that environment. My current rate would be £100 or €120 for an initial 50 minute consultation on this topic. If you'd like to discuss that, that's definitely off-topic for this list and you should contact me directly. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
