IP options
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

ibuf_empty delayed efd
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

dynamic allocation in bsd-poll.c?
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.

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

mput/mget misbehavior
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

SCP
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

Equivalent ssh_config setting for "ssh -N"
Oops. That's -T. From the man page, it doesn't really look like there's an ssh_config option for -N. -----Original Message----- From: openssh-unix-dev [mailto:openssh-unix-dev-bounces+scott_n=xypro.com at mindrot.org] On Behalf Of Scott Neugroschl Sent: Tuesday, August 09, 2016 1:04 PM To: Volker Diels-Grabsch; openssh-unix-dev at mindrot.org Subject: RE: Equivalent ssh_config

ENGINE support?
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

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

remote-remote scp
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

Port Knocking?
