similar to: Authentication protocol

I have been using OpenSSH clients against a number of embedded SSH servers with no problem up till now. Starting with version 6.4p1 password authentication has stopped working against such servers. What happens is that the client enters an infinite loop during the authentication phase. I built OpenSSH 5.9p1 and 6.4p1 in a Linux box so that the client prints out to the screen all of the SSH

I have been looking into this over the weekend, and what I have found might be of interest to OpenSSH developers. First, the bug that triggers the problem is in the embedded system. Second, such as things were changed in 6.4p1, the OpenSSH client seems to be open to a potential DoS attack. The infinite loop described in my previous post is embodied in the last four messages of the 6.4p1 traces.

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

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

I browsed the web and the archive, and apart from someone asking whether anyone else had rsync problems after installing OpenSSH 3.4, I came up empty. Can anyone point me in the right direction to debug this? I've got over 50 GB to keep in sync, and don't know of another elegant way to do it.

Good morning, I am Martin Bodin, a postdoc at the CMM in Santiago de Chile, and I am currently in the process of formalising (a part of) the R language into the Coq proof assistant. This work makes me look frequently at the source code of R. I have noticed a strange line in the file src/main/util.c of the trunk branch:

Hello developers, some informations before I come to the problem: At work we're using Open-SSH 3.4p1 under Solaris 8. I compiled the Open-SSH by myself with gcc-3.1.
