The corrections in the following sections apply to DataPower Gateway version 7.5 in IBM Knowledge Center.





Upgrade
    When you upgrade to 7.5.2, the following changes apply to SSH connection.
    • Disabled diffie-hellman-group-exchange-sha1 and diffie-hellman-group1-sha1 algorithms by default.
    • Disabled MD5-based MAC algorithms.
    • Limited DH-GEX to 4096 bits for Cisco devices.

    Although the key exchange algorithms were updated, they cannot be edited. If you need to enable the legacy algorithm you can use the hidden enable-legacy-kex yes command.
    • The enable-legacy-kex command for the SSH server profile in available in 7.5.2.0.
    • The enable-legacy-kex command for the SSH client profile is available in 7.5.2.7.

    To help you understand the support, review the following supported algorithms and cipher suites.
    Remember the following points for the establishment of an SSH connection.
    • The SSH client always initiates the banner exchange.
    • During the SSH2 banner exchange, use CR+LF termination for the banner.
    • The SSH client ignores any message from the SSH server until the banner exchange.
