"OpenSSH 4.0 has just been released. It will be available from the
mirrors listed at http://www.openssh.com/ shortly.

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0
implementation and includes sftp client and server support.

We would like to thank the OpenSSH community for their continued
support to the project, especially those who contributed source and
bought T-shirts or posters.

We have a new design of T-shirt available, more info on
http://www.openbsd.org/tshirts.html#18

Changes since OpenSSH 3.9:
============================

* ssh(1) now allows the optional specification of an address to bind to
in port forwarding connections (local, remote and dynamic). Please
refer to the documentation for the -L and -R options in the ssh(1)
manual page and the LocalForward and RemoteForward options in the
ssh_config(5) manpage. (Bugzilla #413)

* To control remote bindings while retaining backwards compatibility,
sshd(8)'s GatewayPorts option has been extended. To allow client
specified bind addresses for remote (-R) port forwardings, the server
must be configured with "GatewayPorts clientspecified".

* ssh(1) and ssh-keyscan(1) now support hashing of host names and
addresses added to known_hosts files, controlled by the ssh(1)
HashKnownHosts configuration directive. This option improves user
privacy by hiding which hosts have been visited. At present this
option is off by default, but may be turned on once it receives
sufficient testing.

* Added options for managing keys in known_hosts files to ssh-keygen(1),
including the ability to search for hosts by name, delete hosts by
name and convert an unhashed known_hosts file into one with hashed
names. These are particularly useful for managing known_hosts files
with hashed hostnames.

* Improve account and password expiry support in sshd(8). Ther server
will now warn in advance for both account and password expiry.

* sshd(8) will now log the source of connections denied by AllowUsers,
DenyUsers, AllowGroups and DenyGroups (Bugzilla #909)

* Added AddressFamily option to sshd(8) to allow global control over
IPv4/IPv6 usage. (Bugzilla #989)

* Improved sftp(1) client, including bugfixes and optimisations for the
``ls'' command and command history and editing support using libedit.

* Improved the handling of bad data in authorized_keys files,
eliminating fatal errors on corrupt or very large keys. (Bugzilla
#884)

* Improved connection multiplexing support in ssh(1). Several bugs
have been fixed and a new "command mode" has been added to allow the
control of a running multiplexing master connection, including
checking that it is up, determining its PID and asking it to exit.

* Have scp(1) and sftp(1) wait for the spawned ssh to exit before they
exit themselves. This prevents ssh from being unable to restore
terminal modes (not normally a problem on OpenBSD but common with
-Portable on POSIX platforms). (Bugzilla #950)

* Portable OpenSSH:

- Add *EXPERIMENTAL* BSM audit support for Solaris systems
(Bugzilla #125)

- Enable IPv6 on AIX where possible (see README.platform for
details), working around a misfeature of AIX's getnameinfo.
(Bugzilla #835)

- Teach sshd(8) to write failed login records to btmp for
unsuccessful auth attempts. Currently this is only for password,
keyboard-interactive and challenge/response authentication methods
and only on Linux and HP-UX.

- sshd(8) now sends output from failing PAM session modules to the
user before exiting, similar to the way /etc/nologin is handled

- Store credentials from gssapi-with-mic authentication early enough
to be available to PAM session modules when privsep=yes.

Checksums:
==========

- MD5 (openssh-4.0.tgz) = 7dbf15fe7c294672e8822127f50107d0
- MD5 (openssh-4.0p1.tar.gz) = 122bec49d2cace00b71cc29b5ececed3

"Hi,

The release announcement for OpenSSH 4.0p1 had an incorrect md5sum for the
portable tarball. The correct md5 is below, otherwise you may verify the
integrity of the release using the PGP signature, contained in the file
"openssh-4.0p1.tar.gz.sig" in the release directory.

MD5 (openssh-4.0p1.tar.gz) = 7b36f28fc16e1b7f4ba3c1dca191ac92

Apologies for any confusion,
Damien Miller"

Hi All:

Need your advice on SSH. I have 2 Linux boxes here, A is with OpenSSH-4.0p1; B is with OpenSSH-3.6.1p2. I am trying to setup a passwordless ssh login between these 2. These are the steps:
- ssh-keygen -t dsa on both servers
- exchanging id_dsa.pub; appending the key to authorized_keys2 of the other server.

I managed to ssh login without being prompted for password from A to B;
however it keeps prompting me for password if I were to do it from B to A.

Attached are the printout of attempt to ssh login from B to A:

Any ideas what gone wrong?
Any advices would be greatly appreciated.
