Private key file permissions w/Cygwin OpenSSH on Vista
Thu Sep 13 15:08:00 GMT 2007
Not sure if you are having the exact same issue I had, but I couldn't chmod
the files in cygwin either. Then I realized my home directory was on a
windows share. I was able to cp the files to my local drive and chmod them,
but the changes disappeared when moving the files back to the home
directory. To change my home directory to a local path I ran the following
mkpasswd -l -c -p /home
this made my home directory in the local /home
once this was done I mv all files from the old network share to the local
and chmoded them appropriately and was able to use my ssh with rsa keys
