Dear all, I am currently implementing an experimental key exchange (KEX) algorithm. Unlike current algorithms like DH, mine needs to be able to fail gracefully, and in case of failure, continue with whatever algorithm would have been negotiated if mine was not selected. My strategy for graceful failure is to remove my KEX algorithm from myproposal[KEX_DEFAULT_KEX] and to initiate a new key

Hi! I'm investigating the seccomp filter in openssh and I wanted to know whether the following system calls should be added to the filter: 1. getgroups - do_authentication2->dispatch_run_fatal->sshpkt_fatal->logdie->cleanup_exit->do_cleanup->temporarily_use_uid->getgroups 2. setgroups -

I think I've found a bug with sshd handling audit events for commands (like scp) over ssh1 connections. Specifically, after updating to a recent FreeBSD 6.x with audit support, I'm getting log messages like these when using scp over ssh1: Sep 12 14:13:16 <auth.info> bm55 sshd[12335]: Accepted rsa for xxx from A.B.C.D port 2981 Sep 12 14:13:16 <auth.crit> bm55 sshd[12335]:

Hi, About a year and a half ago I brought up the topic of encrypted hostkeys and posted a patch (http://marc.info/?l=openssh-unix-dev&m=132774431906364&w=2), and while the general reaction seemed receptive to the idea, a few problems were pointed out with the implementation (UI issues, ssh-keysign breakage). I've finally had some spare time in which to get back to this, and I've

The way things are now, input_userauth_request() calls the authmethod, and then does a bunch of checks, like the special case for root. If an authmethod requires a challenge-response conversation, these checks are skipped, unless they are duplicated by the authmethod. For example, in auth2-chall.c, some of the code is duplicated (logging, sending the reply), but the root special case is skipped.

Hi, I installed 3.0.2p1 on our Solaris 8 systems this week (new to ssh), and when I look at the process list for sshd, I see: root 14547 1 0 10:35:29 ? 0:00 /opt/openssh/sbin/sshd root 14548 14547 0 10:35:36 ? 0:01 /opt/openssh/sbin/sshd Process 14547 is the deamon listening on port 22, but process 14548 is my connection from elsewhere. I consider it a design

I have a simple Rails 4 project with two scaffolded models: Practice and Practitioner. I have set these both as habtm and am in the process of adding checkboxes to the Practitioner form so that I can check off the practices that this practitioner belongs to. In the practitioners_controller, I added practice_ids to the practitioner_params permit list, but I am still getting the error: Started

I'm using OpenSSH-2.9.9p2 on Solaris 8 sparc64. 2.9p2 worked fine, but 2.9.9p2+ is giving me trouble with one thing - sshd segfaults if I try to connect and execute a command, such as "ssh machine ls". Otherwise it works great. sshd will fork, and the child process segfaults. CVS snapshot does the same thing. I've narrowed this down somewhat. It will only happen if you use

Hello, in the BSD Authentication system the login script can request environment variables to be set/unset. The call to auth_close() in auth-passwd.c does change the current environment, but those changes are lost for the child environment. It would be really useful to add some kind of mechanism to get those changes into the child environment. I've added two possible solutions. Both

Hello, For a key exchange algorithm I'm working on, I would like to keep a little bit of shared state between the main server process and the processes that clients connect to. So far, I'm considering mmap for the purpose. But I cannot figure out where I need to put the mmap initialization call, where it would be called at server startup (before any fork()s/exec()s), and never again.

It's not a thorough test, but the logging is as we would expect, and everything else looks as expected. A huge thanks to all the people who helped with

This patch adds SMP support to the previous version. Since that has not been merged I have included it in this patch. This should apply cleanly to the tip. Below is the text of the original submittal, slightly updated. Attached is a preliminary patch that adds Intel(R) LaGrande Technology (LT) (Safer Mode Extensions - SMX) support to Xen. While there are still several enhancements needed for

There are a couple of niggles with the sandboxing of the unprivileged child in the privsep code: the empty directory causes namespace pollution, and it requires care to ensure that it is set up properly and remains set up properly. The patch below (against the portable OpenSSH, although the patch against the OpenBSD version is very similar) replaces the fixed empty directory with one that is
