@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?

@Nayana

You DO NOT want to share the private key with anyone!

You can however add the public key to as many nodes as you wish!

If you frequently log into one node and hop to others from there you can also make a new private key for that “landing” node, and share the public key with secondary nodes.

Hey,
Thanks for sharing this article. It is really well explained. You have given 3 alternate options to choose from. Readers need to remember using any one of them would be helpful. I hope that will cleared out the doubts.

@Predrag

Thanks for the enhancement!

Although I can understand your frustration, I would say you need to shift your perspective on Cygwin.

PuTTY is a solution for windows machines to connect to remote nodes. It is very useful, and has extra utilities to enhance its use (pageant). Other windows specific solutions (WinSCP) leverage this functionality since Windows does not have its own SSH agent.

But Cygwin is a solution for windows to Mock a Bash interpreter and common ‘nix utilities. One of those utilities is an SSH Agent. Therefore since a true shell on a ‘nix box would not use PuTTY’s pageant, neither would (or in my opinion should) Cygwin.

Regards,
Eddie

Great tutorial! Thanks.

I had to change line (in .bash_profile) from

ssh-add ~/.ssh/id_dsa

[ -z "$SSH_AGENT_PID" ] && ssh-add ~/.ssh/id_dsa

to avoid asking for password if i do (for example )/usr/bin/startxwin.sh – to start X in session using agent already.

It is pity that cygwin cannot use putty agent ;-(
Best regards.

Thank’s You for this tutorial. I couldn’t find time to figure it out myself.
