Client-Side Authentication Parameters

The authentication method is determined by setting one of the following keywords to “yes”:

• DSAAuthentication

• PasswordAuthentication

• RhostsAuthentication

• RhostsRSAAuthentication

The keyword UseRsh specifies that the rlogin and rsh commands be used, probably due to no Secure Shell support.

The Protocol keyword sets the Secure Shell protocol version to v1 or v2. You can specify both versions separated by a comma. The first version is tried and upon failure, the second version is used.

The IdentityFile keyword specifies an alternate file name to hold the user's private key.

The keyword Cipher specifies the v1 encryption algorithm, which might be blowfish or 3des. The keyword Ciphers specifies an order of preference for the v2 encryption algorithms: 3des-cbc, blowfish-cbc, and aes128–cbc. The commands ssh and scp have a -c option for specifying the encryption algorithm on the command line.
