Hey, Judging from the (private) responses I?ve got, there is quite a bit of interest in the U2F feature I proposed a while ago. Therefore, I?ve taken some time to resolve the remaining issues, and I think the resulting patch (attached to this email) is in quite a good state now. I also posted the new version of the patch to https://bugzilla.mindrot.org/show_bug.cgi?id=2319 (which I?ve opened

I'm writing a PAM module to do authentication through Signal (as in Open Whisper Systems) [1]. I would like to be able to offer (Public key AND Signal) or (Password AND Signal) for authentication. This suggests setting AuthenticationMethods to publickey,keyboard-interactive:pam password,keyboard-interactive:pam However, when PAM is enabled "password" means "show password

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I just came across a contradiction between the man page of AuthenticationMethods and the accepted methods list. According to the sshd_config manual page: """ AuthenticationMethods Specifies the authentication methods that must be successfully completed for a user to be granted access. This option must be followed by one

Hello Damien, Brian and all, thanks for the suggestions. I actually had not considered host-based authentication and looked it up. As I understand from my first quick reading, I would need to specify the clients which are allowed to use host-based auth on the server with a DNS name or an IP, which would not work for a client behind a CG NAT or in a cellular network. Or did I get this wrong?

Hey everyone, Basically, I'm trying to figure out if I can configure sshd to require that the user has a key that has been signed by a trusted user CA *and* is listed separately as an authorised key (or the user has a signed key and a different authorised key)? The closest I've come is having an `authorized_keys` file have two entries consisting of the CA key and a normal key with

I don't see a way to do this currently (unless I am missing something) but I would like to be able to specify, that in order for a user to login, they need to use at least 1 public key from 2 separate key sources.? Specifically this would be when using "AuthenticationMethods publickey,publickey".? Right now requiring 2 public keys for authentication will allow 2 public keys from

Hi, first of: my familiarity with OpenSSH/Pam code-base is very limited.. Please excuse me if some of this does not make any sense or seems stupid! I'm investigating if it is possible for a PAM module to find out which public key was accepted (when 'AuthenticationMethods publickey,keyboard-interactive' is used). From my digging in the source, it seems it is currently not. Would

I added an EXPLICIT AuthenticationMethods publickey,keyboard-interactive + UsePam yes to sshd_config. Now, at connect attempt I get Password: Verification code: Password: Verification code: Password: ... I.e., It's asking for Password, not accepting pubkey AND when given the password (which is correct), and the GA VerificationCode, it simply repeats the credentials request.

Hello all, in order to connect to my SSH servers from untrusted devices like company computers or my smartphone, I set up 2FA with google-authenticator hooked into PAM. However, this is not really 2FA at least for the smartphone, since I use the same device for generating the TANs and it is also at least inconvenient to always require a new TAN for each connection. I do not want to solely rely
