Hello Folks,
I hate to beat an already "terribly beaten horse" but I'd like to say
that I would like the null cipher option to be available. The reason
being is that working for a WAN optimization company, the need to "see"
the unencrypted traffic is paramount in order to reduce SSH's network
foot
I just want to say that I need this too... Please. It's not that
terribly hard.

fusiondog: Could I recommend that you consider doing something positive?
If you are willing to work with upstream (that is, with the developers
of openssh) to get this option included by default in their released
source code, that would make getting it included into future releases of
Ubuntu *much*
I find it frustrating when those that don't understand the value of
something patently reject it without research. FTP and other protocols
make use of kerberos to authenticated securely then transmit the data in
plaintext. This should be trivial to do in ssh, especially if using
RSA/DSA key metho
This is the 'none' cipher patch:

(from http://www.psc.edu/networking/projects/hpn-ssh/)
Since security is so critical, perhaps we should defer judgement to the
OpenSSH mailing lists?

Problem is that SSH performance is still 10-30x slower with encryption.
On a 3.6GHz Intel Penryn with plenty of memory bandwidth [1], we see
around 67MB/s - 109MB/s [2]. Moving from 'secret' aes-128-cbc (the
default) to 'top-secret' aes-256-cbc (the most secure) is almost free.
Moving from MD5 has

For what it's worth, despite claims I've heard to the contrary, this is
not something that has been intentionally disabled versus upstream by
the Debian/Ubuntu packaging, it's not a configure option, and it's not a
trivial one-line change. At minimum, I'd want to disable password

Doing password authentication over 'none' cipher is indeed quite bad
(unless you're on a trusted local network) but RSA/DSA authentication
over an unencrypted transport is totally secure in that no key
information is leaked and it's not possible to authenticate without a
proper key.
Of course, you
I am very unconvinced about this (none implies that *authentication*
happens in plaintext, as far as I know!). I recommend that people
wanting performance use the blowfish-cbc cipher.
