From the OpenSSH FAQ- http://openssh.org/donations.html
"OpenSSH has no wealthy sponsors, nor a business model. In fact, no Commercial Unix or Linux vendor has ever given our project a cent. Naturally, the OpenSSH project requires funds to operate -- particularly so that our team members can meet in person once in a while (at OpenBSD hackathons) to design new ideas."

From the OpenSSH Security page- If you wish to report a security issue in OpenSSH, please contact the private developers list openssh@openssh.com.

A way of ensuring that bugs are proactively found in essential projects like this *isn't* to muddy the development process by establishing a separate security reporting structure, it is to fully fund the one that already exists and works very well. Google rakes in BILLIONS and can't annually fund one developer's worth of money to a project like OpenSSH as a tax deductible donation or written off as R&D? Really?

Actually it is not - it is in base OpenSSH but only in the newest 6.2 release

That means it's not on most Linux distributions unless they've applied it in a patch.

The original Quake server WAS written when John Carmack did not know how to program. And most game servers are still written with complete disregard for quality by people who should not be allowed to program.

I have no idea, who wrote buffer overflows in OpenSSH and what kind of drugs he was on at the time, but there is no excuse for it, either. Theo de Raadt, despite his intentions to keep things secure, is known for many stupid things. However if you look at the history of security bugs in OpenSSH, you will find that most of them, and all recent ones (as in, not a decade old), are very much language-neutral, and would be just as bad if OpenSSH was written in Shiny Sparkly Visual Super Safe Basic # For Retards 2012.8.

Well, I think I have some level of understanding.
Thay ban encrypted VPN, whothout knopwing what a VPN, encryption and telecommunication is.
SSH port forwarding is not VPN but supports encryption.
Email is not VPN but can use encryption for message perusal (like HTTPS and IMAPS in GMail).
GnuPG can do encryption but is not VPN.
And then you can still embed information in almost any data traffic.
Will they arrest all those arses?

You might find the OpenSSH FAQ helpful.

OpenSSH indeed supports Blowfish. You can also configure which algorithms it will accept, and which it will indicate preference for in the KEXINIT. That being said, it's silly to assume that Blowfish is less likely to be subject to buffer overflows or stack bugs than AES. AES is (to my knowledge) the most commonly used crypto algorithm for SSH, and likely has more eyes looking at it, etc etc. I also tend to believe that if there were a buffer overflow bug in OpenSSH, we'd know about it.

Faster still (and a better cipher):

ssh -o Compression=no -o Ciphers=arcfour256 -o MACs=umac64@openssh.com ...

The umac-64 MAC is only supported by OpenSSH AFAIK (though the spec is available to anyone else who wants to). It is faster and has a better security guarantee than HMAC-MD5 (and is way faster than HMAC-SHA1).

Please consider buying one or more of their so-ugly-they're-cute T-shirts.

FYI for those of you who rely on Dreamweaver you can in fact get it to use SFTP without any addons or tweaks. In the remote info under manage sites, in the advanced tab, selecting ftp up top, you can check Use Secure FTP (SFTP). If you run the server yourself, you want to install openssh, the common package name for which is openssh-server and its conf files may be found in /etc/ssh. If you don't run the server, ask your ISP to fire it up if they haven't already.

This of course won't defend you from getting nailed by a keylogger phoning home... but ditching XP and using nano or emacs on *nix of course would help. Do regular backups just in case -- not just the docroot folder but sql if you use that as well.

Actually, you can make a donation specifically to OpenSSH as said on the donation page.
http://openssh.org/donations.html

Of course most OpenSSH people are also OpenBSD people.

Given the average /. reader, I beg to differ on that point.

If you're referring to the average user, then perhaps it would be a valid point that MS was out to screw you for the availability of that one feature (pun intended).

However, if you're even remotely adept at dealing with network apps, then you would be actually screwing yourself by forking over "$200+" for a feature you could actually install for free by using OpenVPN or OpenSSH running on Cygwin.

Just my 2 cents...

I don't mean to be too contrary, but how-do-you-know that the proprietary code should be easier to have altered?

For a few reasons, but here is the main one:

A company could be "bullied" by the government to make certain changes to their code, such as adding a back door. An individual could be bullied as well. But with open source code you can't do that because there is no single owner to bully and there could be people all over the globe willing to run the project from their country, safe from some other government's demands.

The possibility that many eyes could look at open source code (carefully, not casually) does not mean that it happens.

In general, that's true. If we narrow this down to specific projects like Linux, OpenBSD, and OpenSSH, we can say that yes, these projects do receive a lot of very critical inspection. You can find relevant details on the latter two project's websites quite easily.

Someone injecting code into any piece of software would need to be very careful to ensure that...

Good list.

I won't say "it doesn't happen" -- an intentionally weak cryptosystem is one obvious possibility -- but it's a little interesting that nothing's turned up anywhere that we know of.

I'm sure there is a long list of people to thank for that.
Speaking of which, I think I'll start here:

A secure VPN or proxy is a very useful tool if you find yourself using insecure wifi often. Windows XP Pro (and better) offer VPN serving capabilities for at least one user. Alternatively, you could set up a free web proxy on localhost and use Hamachi or OpenSSH for port forwarding. In any case, it's definitely worth the peace of mind knowing that your traffic is at least somewhat obfuscated.

On a side note, I like how you wiki-signed your post :)

Agreed.

OpenSSH is used everywhere by everybody, from a home user to large vendors and corporations making millions of dollars using this great piece of code into their products.

I just donated 100 Euros to the official OpenSSH Donations page:
http://www.openssh.org/donations.html

"So if you accept Debian and Gentoo then its pretty idiotic to nto accept OpenSSH by the same logic, actually the later is more important to linux as a whole than the former two."

The card dons Tux the penguin, the Linux mascotte chosen by Linus himself, the linuxfund.org website has only one picture: The penguin. OpenSSH is developed by the OpenBSD Project.

That's the mismatch right there.

http://news.com.com/2100-1001-230345.html
http://www.openssh.org/

More important is debatable, OpenSSH is not the only ssh2 implementation used on Linux you know (dropbear comes to mind)...

Anyway, I'm not saying OpenSSH or Wikipedia don't deserve a lot of respect from the Linux community and probably can do very good for Linux with the donated money, but for "The Linux Fund" (sorry to be pedantic, but the fund chose "Linux" over many more generic terms and IMHO should stick to it) to favour OpenSSH over so many projects much closer to "Linux" that could use a donation is a smack in the face. And Wikipedia? Come on. While they deserve a lot of support, a fund that chooses to use the "Linux" trademark in its name should be true to it. Next the "Linux fund" start giving money to Mozilla, then OpenOffice.org, all under the name of "Linux"... When you give money to a fund called "The Linux Fund", the money should go to Linux.

Well it's so easy to get one letter wrong:

http://www.openssh.org/

That's what makes programming such a hassle ;)

X.

SSH was under a freer license than GPL, but did use a GPL library. Today OpenSSH (a derivative of SSH) contains no GPL code. Have a look at the OpenSSH history

Security by Default! Support OpenBSD buy CD/T-shirt or donate. And remember to donate to OpenSSH.

http://www.openbsd.org/donations.html
http://www.openssh.org/donations.html

What part of the BSD license does Theo not understand? Apple and SCO aren't "freeloaders", they are using the software under the intended license.

What part of the BSD license do YOU not understand? Does the part that disclaims all WARRANTIES confuse you? The CODE is free to use and open. SUPPORT of the code on the other hand is not in any way an obligation on the heads of the OpenSSH or OpenBSD projects. Theo is asking for financial support so that they can continue to support the code. They are NOT asking for money for the code itself. I am seeing this ridiculous "Theo's fault due to BSD licence" attitude around a lot of places at the moment. So very many people don't seem to be able to grasp the huge distinction between the code itself and the support of the code. If the OpenSSH code were instead under the GPL, those corporations would be obliged to fund it's development? No. Sure if it were GPL, then the companies would have to give back changes. However in this case, we can do without them giving back changes, because they SUCK at it. Sun with all their might, can keep their crap additions to OpenSSH in SunSSH.

Furthermore, what makes Theo think that people want to run OpenSSH? At this point, it's as entrenched as Windows--nobody has a choice.

People DO have choices. It's just that OpenSSH seems to be the best option. Regardless of whether it's free or not, open or closed, people are choosing OpenSSH over the other choices for good reason. OpenSSH became dominant long ago and continues to close the gap, also for good reason.

Yet big corporations who SELL it, do not seem to think that they should throw in some small change (for them) and help to maintain it the best way anybody other than the excellent OpenSSH coders can... money. Sure they don't have to, but they also don't have to get new features and quick bug fixes either.

If the big corporates want OpenSSH to remain of a high quality with quick and PROPER fixes, they can choose to help. Or they can choose to just ignore the problem and then deal with the disaster of finding that even though they are Sun, Apple or Cisco, they DON'T have the expertise in house who can maintain OpenSSH as well as the OpenSSH team. They might think they do, but Sun themselves have shown how little they understand the code and security implications, with their SunSSH branch.

why should you pay OpenBSD for the CDs when you download everything you need in, I don't know, say 10-15 minutes

The cd pack includes a bunch of stickers. :) Plus, the CDs that you buy are bootable on a few platforms, making installation even more of a breeze. Also, if you don't want to order discs - after you find out that OpenBSD is so very excellent, you can pick up a swanky shirt or just donate some cash to keep the project alive and coding. That way, you get more releases in the future and more great software like OpenSSH, OpenBGPD, CARP, pf, and pretty soon, OpenCVS.

http://openssh.org/manual.html ,and this covers both the man pages for the application, as wel as the RFC's on the protocol and some additional extensions.

What is your problem? The documentation is top-notch, written by mostly the same team that creates OpenBSD (which prides itself in maintaining the most up-to-date, comprehensive manuals).

In the true tradition of Unices, the manual pages ARE the documentation. If you can't understand the man pages, then you should get another job or hobby. Seriously. If you think 'high-level knowledge' is a prerequisite for reading a bloody manual, you're not even trying to understand that manual. What did you expect? Some linux-like 'how-to', written by an unknown 13y. old, which showed you exactly what keys to punch on your keyboard, in order to configure a very specific setup that particular 13y. old envisioned?

It's a sad, sad world, full of blighted idiots who refuse to think for themselves..

Well, no. If you read the OpenSSH project history here and the original SSH license here, it is clear that OpenSSH is not infringing anything.

The licence used for the version on which OpenSSH was based states that it can be freely used for any purpose, that derived works must be clearly identified as derived works (OpenSSH is so identified), and that if they are incompatible with the RFC protocol, they may not be called SSH or Secure Shell. By implication, the OpenSSH team could have just called it "SSH" and they would still not be infringing, under the terms of the original license, which allows derivative works to be called simply "SSH" or "Secure Shell," as I read it.

Since those days, SSH has become a commercial, proprietary, and monetized product, and they may not like the fact that it was once under a free license that allowed projects like OpenSSH to happen, but instead of whining about "They did just what they were allowed to do, boohoohoo!" they should just get out there and compete on merits like everyone else. Price, too, is a merit, and if the higher cost and proprietary license of SSH is not, in the eye of the purchaser, justified by any superior technical merits it may have, that's tough.

Like in all software, there is security issues, but it's not quite as bleak as the list you presented (one reflect FreeBSD on Alpha, another about a script on Debian, if I remember correctly, some changes from default config (like disabling Priv Sep)).

Have a look at OpenSSH Security for the various security issues. The opensSL project has a similar page.

Yes, the most popular SSH implementation is OpenSSH, maintained by OpenBSD. OpenBSD is also paranoid about security, so as a result, Linux distros get a paranoid-level secure SSH daemon.

OpenBSD is great, by the way. You should give it a try. I use it on my laptop. It supports my laptop better than Linux does. For example, in Linux, my laptop won't suspend. On OpenBSD, not only does it suspend, but it also hibernates. Also, Centrino wireless is much more annoying to get working on Linux. But on OpenBSD, everything works great, with little modifications needed.

Moving to OpenBSD as my primary platform also got me closer to real Unix roots. Got me away from bash, which was causing me to do really unportable things in shell scripts. Got me away from glibc, so I don't do as many unportable things in C programs anymore because I'm no longer reading GNU manpages. And, my Makefiles aren't nearly as atrocious as they once were, now that I'm not using GNU make.

The BSD experience really is different from the Linux one. IMHO in a positive way. If you're presently a Linux devotee I recommend you give some other form of Unix a good solid try. It might just change the way you think about the whole deal.

That's why we have OpenSSH.

Still, there are situations where these would be unworkable: severe cost restrictions might rule out encryption, or a moving transmitter might rule out a highly directional antenna on the reciever. What is needed is more information: what are your limitations? Just what is the mystery device you're designing intended to do?

Without any futher information, all I can suggest is to look into programs like SSH and standards like IPSec; these might give you a good idea of where to start if you can spare some simple computing hardware at each end. Ultimately, since you have a software background, I would suggest viewing the system you're creating as not unlike a VPN: you must create a secure trust boundary across a network which may harbor attackers. There's already significant development in identifying spoofed senders across the Internet; what you have to do is to transfer those concepts into the world of radio. While the two domains are certainly not isomorphic, there is a large body of knowledge that can be mapped from one to the other. The links I have given you, and the advice from other posters in this thread, should give you a good start.
