Oh, and I'm using gmirror with a couple of disks. There's also a zip drive attached (which has always worked), but I've not been using it in the last three days, so it was not "active" when the system paniced. >-- even if it's a case of taking > a photo of your screen and sticking it on a pasteboard site somewhere. Not much to see, really: the above message (which should be *almost* exact, since I copied it by hand) and a backtrace which doesn't mean much. Nothing else. > Hmmm... sym(4) looks like it's fairly elderly, implying the same is > probably true of your hardware. Sure. > Is it possible your disk controller is succumbing to the vagaries of age? I have never seen any little trouble with such a card (I've had more than one here and at customers'); thought it might actually be dying, I really find it strange that it started as soon as I upgraded from 9.3 to 10.2... bye & Thanks a lot av.

I intend to remove them from FreeBSD-STABLE this weekend. The HPN patches were of limited usefulness and required a great deal of effort to maintain in our tree. The None cipher patch was less onerous, but it was a terrible idea with a very small user base since it was a compile-time option and off by default. The HPN-related configuration variables have been marked deprecated, while those related to the None cipher have been marked unsupported. This means that the former will be accepted with a warning, whereas the latter will result in an error. Most users will not be affected by this change. Those who are should switch to the openssh-portable port, which still offers both patches, with HPN enabled by default. It is expected that FreeBSD 10.3 will ship with OpenSSH 7.1p2, with a number of modifications intended to reduce the impact of upstream changes on existing systems.

I have not looked at the code, but my former colleagues at the high performance research network ESnet claim at http://fasterdata.es.net/data-transfer-tools/say-no-to-scp/ that the internal buffers and effective window size have recently been increased from 64KB to 1MB an allow for transfer rates of up to 140 Mbps over a link with 53 ms. latency. With the HPN patches, they report 1.2 Gbps, making HPN patches still significant over high latency paths. That said, scp still performed poorly when compared to other technologies (i.e. GridFTP) for bulk data transfer over high-latency high-bandwidth links. (ESnet provides links of up to 400 Gbps between the US and Europe as well as within the US, so this sort of thing is quite important to them.) -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 From owner-freebsd-stable@freebsd.org Sat Jan 23 20:33:06 2016 Return-Path: Delivered-To: freebsd-stable@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 4FCDDA8FF23; Sat, 23 Jan 2016 20:33:06 +0000 (UTC) (envelope-from des@des.no) Received: from smtp.des.no (smtp.des.no [194.63.250.102]) by mx1.freebsd.org (Postfix) with ESMTP id 1B0A510D7; Sat, 23 Jan 2016 20:33:05 +0000 (UTC) (envelope-from des@des.no) Received: from desk.des.no (smtp.des.no [194.63.250.102]) by smtp.des.no (Postfix) with ESMTP id AE5195765; Sat, 23 Jan 2016 20:33:04 +0000 (UTC) Received: by desk.des.no (Postfix, from userid 1001) id 2A9B5481E4; Sat, 23 Jan 2016 21:33:05 +0100 (CET) From: =?utf-8?Q?Dag-Erling_Sm=C3=B8rgrav?= To: Kevin Oberman Cc: Julian Elischer , FreeBSD Current , FreeBSD-STABLE Mailing List , freebsd-security@freebsd.org Subject: Re: HPN and None options in OpenSSH References: <86mvrxvg79.fsf@desk.des.no> <56A2DE54.6070603@freebsd.org> <861t98e1el.fsf@desk.des.no> Date: Sat, 23 Jan 2016 21:33:05 +0100 In-Reply-To: (Kevin Oberman's message of "Sat, 23 Jan 2016 09:15:36 -0800") Message-ID: <86wpr0c9z2.fsf@desk.des.no> User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/24.5 (berkeley-unix) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.20 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 23 Jan 2016 20:33:06 -0000 Kevin Oberman writes: > Dag-Erling Sm=C3=B8rgrav writes: > > Julian Elischer writes: > > > what is the internal window size in the new ssh? > > 64 kB. > Are you sure of this? Sorry, I was thinking of 6.6 (in stable/10). The buffer code in 7.1 supports dynamically-sized buffers with a hard limit of 128 MB. The default window size for client sessions is 2 MB, or 1 MB if associated with a tty. I'm not sure what the maximum size is. Note that scp, sftp etc. count as client sessions. X11 and agent forwarding use different (smaller) windows which improve latency at the cost of throughput. > [...] scp still performed poorly when compared to other technologies scp is a horrible protocol, use sftp or (preferably) rsync over ssh.

I'm not sure what the maximum size is. I'll try to do some cross-country or trans-Atlantic testing this weekend or next week, using a mix of ssh versions and HPN-patched versus not (and CentOS vs. FreeBSD vs. possibly Debian unstable with the 4.2+ kernel as yet another degree of freedom). I'll see what basic results I can get and we can update fasterdata.es.net as necessary. > That said, scp still performed poorly when compared to other technologies > (i.e. GridFTP) for bulk data transfer over high-latency high-bandwidth > links.

That it is! > scp is a horrible protocol, use sftp or (preferably) rsync over ssh. I still think over ssh transport is lousy for bulk-data transfers, but it is the one thing that's generally installed by default on every OS and and is allowed by many firewalls. And, of course, it encrypts in flight. Certainly gridFTP, aspera (if you can afford it!) and other packages optimized for bulk data transfer will work better. michael ESnet
