SSH Client Authentication
SSH client authentication by password is enabled by default, with the username/
password being “anonymous”.
The user must configure the following information for authentication:
• The authentication method to be used.
• The username/password or public/private key pair.
In order to support auto configuration of an out-of-box device (device with factory
default configuration), SSH server authentication is disabled by default.
Supported Algorithms
When the connection between a device (as an SSH client) and an SSH server is
established, the client and SSH server exchange data in order to determine the
algorithms to use in the SSH transport layer.
The following algorithms are supported on the client side:
• Key Exchange Algorithm-diffie-hellman
• Encryption Algorithms
- aes128-cbc
- 3des-cbc
- arcfour
- aes192-cbc
- aes256-cbc
• Message Authentication Code Algorithms
- hmac-sha1
- hmac-md5
NOTE Compression algorithms are not supported.
