AES encryption for SSH2.
27
• OpenSSH 3.5_p1 and 3.6.1p2
• Solaris Sun-SSH-1.0
NOTE
The PowerConnect B-Series TI24X devices support client public key sizes of 2048 bits or less.
Supported features
SSH2 (Secure Shell version 2 protocol) provides an SSH server. The SSH server allows secure
remote access management functions on a device. SSH provides a function that is similar to
Telnet, but unlike Telnet, SSH provides a secure, encrypted connection.
SSH2 support includes the following:
• Key exchange methods are diffie-hellman-group1-sha1
• The public key algorithm is ssh-dss.
• Encryption is provided with 3des-cbc, aes128-cbc, aes192-cbc or aes256-cbc. AES encryption
has been adopted by the U.S. Government as an encryption standard.Refer to “AES encryption
for SSH2.” on page 912.
• Data integrity is ensured with hmac-sha1.
• Supported authentication methods are Password and publickey.
Unsupported features
The following are not supported with SSH2
• Compression
• TCP/IP port forwarding, X11 forwarding, and secure file transfer
• SSH version 1
AES encryption for SSH2.
Encryption is provided with 3des-cbc, aes128-cbc, aes192-cbc or aes256-cbc. AES encryption has
been adopted by the U.S. Government as an encryption standard.
A total of five SSH connections can be active on a device. To display information about SSH
connections, enter the following command.
You can also use the show who command to display information about SSH connections
