I looked around for a while, but couldn't find any code for requiring multiple authentication mechanisms in openssh. So I wrote an implemention. I thought at first I should change the PasswordAuthentication, PubkeyAuthentication, etc. keywords to allow no/yes/required. But there's some funky stuff in auth2.c with respect to keyboard interactive auth that would make this kind of

Hello my name is Derek Bodin. ? As a personal side project I am trying to create a java SSH2 server.? I have so far been able to work my through the transportation protocol and the user authentication protocol.? My question is when the authentication protocol starts OpenSSH will sit and hang waiting for the server to send a SSH_MSG_USERAUTH_FAILURE packet and a list of appropriate authentication

Hi all, I'm working with a pure PHP implementation of the SSH2 protocol. I've read the rfc and the thousands of lines in this project: http://phpseclib.sourceforge.net/ I'm simply trying to add a feature that will capture and display the USERAUTH_BANNER displayed by Open sshd prior to login. When I connect to my opensshd server configured with the banner from openssh on any

OpenBSD tree is heading into a lock and this includes OpenSSH. So we are winding up for a 3.5 release. If we can get people to test the current snapshots and report any problems that would improve the odds that your platform won't be broke for 3.5. Issues I know off of right now. 1. I can't test NeXT. So I TRULY need someone in that community to test for me. Last I heard there was
