AES encryption for SSH2
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
To terminate an active connection, enter the following command
TurboIron#kill ssh 1
Syntax: kill ssh
Configuring SSH2
The Brocade implementation of SSH2 supports two kinds of user authentication:
• DSA challenge-response authentication, where a collection of public keys are stored on the
device. Only clients with a private key that corresponds to one of the stored public keys can
gain access to the device using SSH.
NOTE
SSH2 supports and validates DSA keys only. It does not support or validate SSH1 RSA keys.
