I want to login to the linux server from windows by putty!

SSH Server: centos 6.5

SSH client: win10+putty+yubikey+GPG4win

It's seem to the putty can't access the gpg-agent.

C:\Program Files (x86)\GNU\GnuPG>ssh-add -l
Could not open a connection to your authentication agent.

The details as below:

C:\Program Files (x86)\GNU\GnuPG>ssh-add -l
Could not open a connection to your authentication agent.

when I logon with putty.("attemp authentication using pageant" checked)

Get errors:

Disconnected: NO supported authentication methods available(server sent: publikey,gssapi-keyex,gssapi-with-mic)


what's the reason for that! Any help, greatly appreciated!Thanks!

Solution:

It's no need to gpg-agent.Download a pageant from here

http://smartcard-auth.de/ssh-en.html and It's OK!
