2. IdentityFile is the right answer. It is an option of the ssh command : IdentityFile
   Specifies a file from which the user’s RSA or DSA authentication identity is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for protocol version 2. Additionally, any identities represented by the authentication agent will be used for authentication.
