HP-UX Secure Shell A.04.40.005, A.04.40.006 and A.04.40.007Release Notes

HP-UX Secure Shell A.04.40.005, A.04.40.006 and A.04.40.007
New Features in OpenSSH 4.4p1
Chapter14
This enhancement enables clients to connect to multiple sshd servers
running on non-standard ports with different hostkeys. Connections
using the default port (port 22) and ones that use HostKeyAlias
(regardless of the port) are not affected by this enhancement.
Added ExitOnForwardFailure Option
In earlier versions of OpenSSH, ssh does not terminate if port
forwarding requests fail. Starting with OpenSSH 4.4p1, an
ExitOnForwardFailure option is added so that ssh exits with a non-zero
value if port forwarding requests fail.
Example 4 Example Depicting the Usage of ExitOnForwardFailure Option
Server side:
# /opt/ssh/sbin/sshd
Client side:
# ssh -o "ExitOnForwardFailure yes" -L xxxx:2222:host2:23 host1
Password: <correct password>
channel_setup_fwd_listener: getaddrinfo(xxxx): no address
associated with name
Could not request local forwarding.
If port forwarding fails, ssh exits with the above error message.
Extended sshd_config(5) "SubSystem" Declarations
The subsystem option is used to configure the external subsystem, such
as sftp-server. The subsystem name and a command are passed as
arguments to the subsystem option for configuration in the prior
OpenSSH releases.
Following is the syntax for the Subsystem directive:
Subsystem <subsystem name><subsystem command>.
The <subsystem command> parameter now accepts command-line
arguments.
In earlier versions of OpenSSH, <subsystem command> does not accept
command-line arguments.
