Does anyone have a patch (doesn't have to be official) to enable the "none" cipher? I need to examine some wire protocol stuff ---- Scott Neugroschl XYPRO Technologies scott_n at xypro.com 805-583-2874 x133

You need to disable ?ChallengeResponse? (aka keyboard-interactive) authentication, not password authentication, to protect against this attack.

I'm seeing something similar to bug 1179 (https://bugzilla.mindrot.org/show_bug.cgi?id=1179), even with the reordered IP options check. For some reason, getsockopt is returning an IP options of length 2, value 00 00. Would Mark Weindling's original patch (https://bugzilla.mindrot.org/attachment.cgi?id=1105) break anything if I incorporated it? Platform: HP NonStop S7000 series

A couple of notes about mget/mput in SFTP (5.1p1). 1. They aren't documented in the SFTP man page 2 They misbehave -- "mput a.txt b.txt" copies a.txt to b.txt on the server "mput *.txt b.txt" copies the first wildcard match to b.txt on the server "mput a.txt b.txt c.txt" copies a.txt to b.txt on the server "mput a.txt

I'm using 5.0p1 (Yeah, yeah. I know.). For various reasons, I am unable to upgrade to the latest and greatest, which probably would solve my problem. Here's my question. When doing an scp from remote to local (e.g.: scp user at host:remote localfile), is there any way to specify the path to the remote scp? Or do I have to patch the code to allow it? ---- Scott

I'm seeing something unusual in 5.0p1. Let me start by saying that I'm on kind of an oddball system (HP NonStop). What I'm seeing is that at the end of an scp session, the server gets stuck in a loop. First I see a shutdown failure, followed by looping on an "ibuf_empty delayed efd 9/(0)" condition. This may have to do with some minor semantic differences in the way the

I'm wondering about the rationale behind the allocation of the fd_set for the select() call in bsd-poll.c. Is there a reason we're dynamically allocating the fd_sets using nmemb, rather than simply putting three fd_set variables on the stack, followed by FD_ZERO calls? This seems to make life more difficult, as evidenced by the "goto out" statement, needed to free the memory.

Is there a particular reason that sshd sets IPV6_V6ONLY on listen sockets? ---- Scott Neugroschl XYPRO Technology Corporation scott_n at xypro.com 805-583-2874

Hi everyone, I know scp is kind of the red-headed stepchild of the suite, but I'd like to propose an extension to the syntax for remote-remote passthrough using the "-3" option. Currently the syntax is essentially scp -3 [ -P port ] [user@]host1:file [user@]host2:file This is great, as long as both remotes are on the same port. It causes difficulties if host1 and host2 are not

I'm trying to add an ENGINE to OpenSSH, and am looking at scard.c and scard-opensc.c as an example. I have a couple of questions -- 1. in both of them, in sc_get_engine(), the returned ENGINE is declared static, but it's overwritten each call. Is sc_get_engine intended to be called only once? When is ENGINE_free() called? 2. Where is the returned ENGINE used? Where is

I'm looking at replacing some algorithms with different implementations, and I'm having some problems with the AES CTR mode algorithms.

Quoth Iain: >I'm not sure if the work being done to allow OpenSSH to be built without OpenSSL includes SHA-1 support. Hi Iain. I haven't heard of this effort before. Can you give a few more details?

I haven't been keeping up with the internals, I'm afraid. Does OpenSSH have support for Port Knocking? I might be interested in looking into that, as a way of reacquainting myself with the current code base. --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |

I read an article today about keyboard interactive auth allowing bruteforcing. I'm afraid I have minimal understanding of what keyboard-interactive really does.

Oops. That's -T.

Hi guys, Given that internal-sftp is the only way to support chrooted users, is there any particular reason why sftp-server is still the default SFTP subsystem? --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |
