Yubico Forum

I just finished configuring SSH on my Ubuntu 10.10 64bit desktop to use my Yubikey via PAM. This is tested and working.

I regularly connect to this machine using NoMachine, and it is running the Neatx server. This was installed using these instructions:

I assumed that once SSH was using my Yubikey that NoMachine would also require my Yubikey. They both use port 22, and I thought that NoMachine was tunneling through SSH. Apparently I'm wrong somehow. SSH required me to enter my password + yubikey OTP; however, NoMachine only works with my password. It's as if I never configured the Yubikey. If I enter the OTP, my login fails. If I enter just my password, it works.

I would appreciate any hints or information to get NoMachine/Neatx to require my Yubikey OTP. Thanks!

I found this information on user authentication in NX:

From the article:
---
To verify the password, NX will submit the user's credentials to the SSH subsystem. If SSH guarantees the access, then NX will allow the user to enter the session.

It seems like NX should be authenticating using the yubikey if SSH is. I'd appreciate any help or input.

Did you find a solution for this?

Never mind, I found a solution already! It seems that Nomachine expects the password prompt to be
and not So I modified the source of pam_yubikey.c a little, and voila, it's working!
