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

HP-UX Secure Shell A04.40.006 and A.04.40.007
New Features in OpenSSH 4.4p1
Chapter14
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.
Replacement of malloc (3) and realloc (3) Invocations
Starting with OpenSSH 4.4p1, all integer overflow susceptible
invocations of malloc() and realloc() are replaced with xcalloc()
and xasprintf() failure-checked allocation functions.
