Hi,

I have just uploaded a new version of OpenSSH.

**********************************************************************
***            Please note that this is a TEST VERSION.            ***
**********************************************************************

It's not a final version but is created from the current OpenSSH
CVS repository. I have added this version here to allow a bit of
testing what will be new in the next official version of OpenSSH.

To update your installation, click on the "Install Cygwin now" link on
the http://sources.redhat.com/cygwin web page.  This downloads setup.exe
to your system. Run setup and answer all of the questions.

**********************************************************************
*** PLEASE, PLEASE, PLEASE, choose a mirror site for your download ***
**********************************************************************

even if it might take a will until this new archive is propagated
to the mirrors. The 'sources.redhat.com' site is badly overloaded.

Ok, what's new and of interest:

- F-SECURE 2.0.12 support. This means, that SSH2 authentication
  with F-SECURE is possible now. This should work in both
  directions. Personally I have only tested the client side.

- -R portforwarding using SSH2 protocol.

- New SSH2 RSA authentication work and -R portforwarding for SSH2.

  The new RSA authentications works similar to the current SSH2 DSA
  keys, but requires a little modification to config files. Currently
  RSA key cannot be shared between SSH1 and SSH2.

  To generate keys, ssh-keygen now has a type '-t' parameter. Valid
  types are 'rsa1' (for SSH1 RSA keys), 'rsa' (SSH2 RSA) and 'dsa'
  (SSH2 DSA). Eg. "ssh-keygen -t rsa -f ~/.ssh/id_rsa" will generate
  a new SSH2 RSA key.

  For public key authentication, just copy the public portion of the
  RSA key into your ~/.ssh/authorized_keys2 file. It is normal for the
  public RSA keys to be shorter than DSA keys.

  SSH2 RSA keys are fully supported by ssh-agent. Keys are tried in the
  order in which they are added to the agent, so 'ssh-add' your RSA key
  first if you want to try it out.

  For the server, all hostkeys are now unified and sshd will
  automatically detect the type of a host key. The 'HostDSAKey'
  option is therefore  deprecated in favor of 'HostKey'. To specify
  RSA and DSA keys for SSH2 use, just use more 'HostKey' options.
  The 'DSAAuthentication' option is  deprecated in favour of the
  general 'PubkeyAuthentication' option.

  The host key section of my sshd_config looks like this:

  HostKey /etc/ssh/ssh_host_key
  HostKey /etc/ssh/ssh_host_rsa_key
  HostKey /etc/ssh/ssh_host_dsa_key

  For the client, the 'IdentityFile2' option is deprecated in favor of
  an autodetecting 'IdentityFile' option. You can specify rsa1, dsa and
  rsa keys using this option.

  RSA pubkey auth seems a little quicker than DSA and it is not
  vulnerable to the problems described in the WARNING.RNG file in
  the source archive.

- ssh-config now asks for creating the SSH2 RSA key files described
  above. Additionally it creates some default entries for the "HostKey"
  lines in /etc/ssh_config and /etc/sshd_config. However, these lines
  are in comments to give you the choice which host keys you want to use.

  This ssh-config will not be the final version. I'm planning to change
  it so that the HostKey lines in the config files are created according
  to the just created or already existing host key files and I want to
  split up ssh-config into two files, one for the host configuration
  and one for the user configuration.

Have fun,
Corinna
