No. I wasn't "making assumptions", I was "making observations of reality" and explaining to the very nice people that an SSHD on a server with dynamic content was not a reliable backup tool due to those observations. They had to dump the project, and I gave them back the consulting money out of ethical concern that I could not do what they'd expected. I'm asking a purely practical question: how much does Cygwin OpenSSH get used, due to the other limitations of the NTFS filesystem causing locks and timeouts of transfer processes?

The client certainly is, and I've even used the daemon myself in the last few years to do some port forwarding for clients.

I'm a bit concerned that Cygwin users will muck with the Microsoft sshd to enable the Cygwin daemon they personally expect, and cause their own IT departments to scream bloody murder when they realize some developer replaced the approved management daemon on their laptop. I'm bringing popcorn for that one. > Corinna > > -- > Corinna Vinschen > Cygwin Maintainer > Red Hat > _______________________________________________ > openssh-unix-dev mailing list > openssh-unix-dev@xxxxxxxxxxx > https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
