Happy to help out @Greg. In my Linux world all programs just seem to know to check for the standard ssh key conventions, but getting a password free world on my windows devices takes a bit of setup.

Thank you immensely for this tutorial! Every time I get set up with a new Windows box at whatever job I’m at, I hate having to go through and try to figure out how to get all the connectivity between servers working. This lays it out perfectly. Thanks!

@Carlos
Glad you found it helpful!

Most passwords are only 8-12 characters but typing it again and again through a full work week really adds up right??

Great tutorial!
I really like the topic “Repetitive Entry Avoidance (A.K.A. Enter the passphrase once, and only once”.
My Cygwin asks me for the passphrase only once now. It works fine.
Thank you very much!
Carlos.

@John – Not sure I follow completely. Cygwin is not a server, if provides command line utilities to mock a ‘nix environment’s utilities. That includes an SSH client, and SSH agent for authorization, but it wouldn’t support external connections comming in unless you have an ssh server running on the machine as well.

What is the scenario that you are trying to use PuTTY to call back to the same machine? Maybe we can work towards a solution for you.

When I connected to the Cygwin server, via putty + auth .ppk file there’s a problem .

The server returns Keys refused. But the strange this is that if i use “ssh -v localhost” from within Cygwin, it will work! Any ideas?

@Tom The key is independent of the id. just copy the public key under each remote user’s home path, in .ssh. Your generated private key should work. For cygwin you will need to specify the private key under the connection settings.The key is independent of the id. just copy the public key under each remote user’s home path, in .ssh.

Hope that helps,

Can you set up multiple ID’s for SFTP on cygwin, and generate keys for each id?
