SSH - tool

Hello ,

In my new project we start to use the following commands : ssh , scp and sftp  .
Server: hp-ux
Environment : ksh
Ssh version : 2

I have a few question about the ssh definition :

1. Description:
         When we connect to user via script ( batch mode ) by using the command "ssh -l remote_user remote_host"  - this session is stuck ( wait input from user - password).
      What we need to perform exactly for "ssh" command so it will fail in case it wait input ( in "scp" command we use '-B' flag )?

2. Description: For time out limit we use TMOUT in ksh , timeout in tcl and expect .

       Please explain how we can define timeout in ssh tool?

3. When I connect to remote user at the first time I get the following message :

 The authenticity of host '<remote_machine> (XXX.XXX.XXX.XXX)' can't be established.
Are you sure you want to continue connecting (yes/no)?

  How we can avoid this massage at any time ?

Thanks in advance .....
