Bug Description

ssh-keyscan defaults to rsa1 keys which isn't overly helpful seeing as our packages default to disabling protocol 1 entirely in the server config. Could it please be made 'rsa' instead?

This was apparently recently fixed upstream (post-5.0p1).

Fixed in OpenSSH 5.1p1; I'll be aiming to get this into Intrepid.

This bug was fixed in the package openssh - 1:5.1p1-1ubuntu1

---------------
openssh (1:5.1p1-1ubuntu1) intrepid; urgency=low

  * Resynchronise with Debian. Remaining changes:
    - Add support for registering ConsoleKit sessions on login.
    - Drop openssh-blacklist and openssh-blacklist-extra to Suggests; they
      take up a lot of CD space, and I suspect that rolling them out in
      security updates has covered most affected systems now.

openssh (1:5.1p1-1) unstable; urgency=low

  * New upstream release (closes: #474301). Important changes not previously
    backported to 4.7p1:
    - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
      + Added chroot(2) support for sshd(8), controlled by a new option
        "ChrootDirectory" (closes: #139047, LP: #24777).
      + Linked sftp-server(8) into sshd(8). The internal sftp server is used
        when the command "internal-sftp" is specified in a Subsystem or
        ForceCommand declaration. When used with ChrootDirectory, the
        internal sftp server requires no special configuration of files
        inside the chroot environment.
      + Added a protocol extension method "<email address hidden>" for
        sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
        prefers this if available (closes: #308561).
      + Removed the fixed limit of 100 file handles in sftp-server(8).
      + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
        keys when in inetd mode and protocol 2 connections are negotiated.
        This speeds up protocol 2 connections to inetd-mode servers that
        also allow Protocol 1.
      + Accept the PermitRootLogin directive in a sshd_config(5) Match
        block. Allows for, e.g. permitting root only from the local network.
      + Reworked sftp(1) argument splitting and escaping to be more
        internally consistent (i.e. between sftp commands) and more
        consistent with sh(1). Please note that this will change the
        interpretation of some quoted strings, especially those with
        embedded backslash escape sequences.
      + Support "Banner=none" in sshd_config(5) to disable sending of a
        pre-login banner (e.g. in a Match block).
      + ssh(1) ProxyCommands are now executed with $SHELL rather than
        /bin/sh.
      + ssh(1)'s ConnectTimeout option is now applied to both the TCP
        connection and the SSH banner exchange (previously it just covered
        the TCP connection). This allows callers of ssh(1) to better detect
        and deal with stuck servers that accept a TCP connection but don't
        progress the protocol, and also makes ConnectTimeout useful for
        connections via a ProxyCommand.
      + scp(1) incorrectly reported "stalled" on slow copies (closes:
        #140828).
      + scp(1) date underflow for timestamps before epoch.
      + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
        instead of the current standard RRSIG.
      + Correctly drain ACKs when a sftp(1) upload write fails midway,
        avoids a fatal() exit from what should be a recoverable condition.
      + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh...
