used. The highest version of SSH2 supported by both the Brocade device and the client is the version

that is used for the session. Once the SSH2 version is negotiated, the encryption algorithm with the

highest security ranking is selected to be used for the session.

Brocade devices also support Secure Copy (SCP) for securely transferring files between a Brocade

device and SCP-enabled remote hosts.

NOTE

The SSH feature includes software that is copyright Allegro Software Development Corporation.

SSH2 is supported in the Layer 2 and Layer 3 codes.

SSH2 is a substantial revision of Secure Shell, comprising the following hybrid protocols and

definitions:

• SSH Transport Layer Protocol

• SSH Authentication Protocol

• SSH Connection Protocol

• SECSH Public Key File Format

• SSH Fingerprint Format

• SSH Protocol Assigned Numbers

• SSH Transport Layer Encryption Modes

• SCP/SSH URI Format

Tested SSH2 clients

The following SSH clients have been tested with SSH2:

• SSH Secure Shell 3.2.3

• Van Dyke SecureCRT 5.2.2

• F-Secure SSH Client 5.3 and 6.0

• PuTTY 0.62

NOTE

SSH session may drop when using PuTTY on Windows system and left idle for more than 45 minutes.

• OpenSSH 4.3p2

• Brocade FastIron SSH Client

NOTE

Supported SSH client public key sizes are 1024 or 2048 bits for DSA keys and RSA keys.

SSH2 supported features

SSH2 (Secure Shell version 2 protocol) provides an SSH server and an SSH client. The SSH server

allows secure remote access management functions on a Brocade device. SSH provides a function

that is similar to Telnet, but unlike Telnet, SSH provides a secure, encrypted connection.

Brocade SSH2 support includes the following:

• Key exchange methods are diffie-hellman-group1-sha1.

• The supported public key algorithms are ssh-dss and ssh-rsa .
