Description Use the
ssh2 command to establish a connection to an SSH server, and specify the
preferred key exchange algorithm, encryption algorithms, and HMAC algorithms
of the client and the server.
Note that when the client’s authentication method is publickey, the client needs to
get the local private key for validation. As the publickey authentication includes
RSA and DSA algorithms, you must specify an algorithm (by using the
identity-key keyword) in order to get the correct data for the local private key.
Example # Login to remote SSH2 server 10.214.50.51, setting the algorithms as follows:
■ Preferred key exchange algorithm: dh-group1
■ Preferred encryption algorithm from server to client: AES128
■ Preferred HMAC algorithm from client to server: MD5
■ Preferred HMAC algorithm from server to client: SHA1-96.
