I have no idea.

It's weird that ssh apparently tries to create the directory as if it's missing. You didn't change the cygdrive prefix in /etc/fstab by any chance? Also, usually your Windows home folder is not /cygdrive/c/$USERNAME but /cygdrive/c/Users/$USERNAME. Are you sure that's not the problem here? > The authenticity of host 'destination (192.168.11.7)' can't be > established. RSA key fingerprint is > SHA256:WKewPf3j9Vljltmsnr/cwZmr0XBy8L5E6Chwp1gWK4g.

What does icacls print for .ssh? > Permissions on all file in that folder are `-rw-r--r--`. All files? Even the private keys? The permissions for private keys should be 0600. What does `getent passwd <your cygwin username>' print? Does the homedir differ from the value of $HOME? Can you run ssh under strace as in $ strace -o ssh.trace ssh destination and provide the trace output? It might contain a hint why ssh thinks it has to create the folder. What you could also try is this: Disable the db_home entry in nsswitch.conf and create a mount point instead, e.g.: $ cat > /etc/fstab.d/$USER <<EOF C:/Users/$USER /home/$USER ntfs binary 0 0 EOF That makes your home dir /home/<username> in Cygwin. Just start a new shell for testing. Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
