How to automatically enter password in a script?
Hi
I'm working with AIX 6.1
I would like to ssh to a server without entering password ( to monitor something) but there's no way to do that by authentication keys, so I need to write a script which can ssh to that server without entering password ( no need to hide passsword in the script, just an user account to monitor ).
Can someone help me please

pam_ssh
PAM_SSH(8) BSD System Manager's Manual PAM_SSH(8) NAME
pam_ssh -- authentication and session management with SSH private keys SYNOPSIS
[service-name] module-type control-flag pam_ssh [options] DESCRIPTION
The SSH authentication service module for PAM, pam_ssh provides functionality for two PAM categories: authentication and session management. In terms of the module-type parameter, they are the ``auth'' and ``session'' features. SSH Authentication Module The SSH authentication component provides a function to verify the identity of a user (pam_sm_authenticate()), by prompting the user for a passphrase and verifying that it can decrypt the target user's SSH key using that passphrase. The following options may be passed to the authentication module: use_first_pass If the authentication module is not the first in the stack, and a previous module obtained the user's password, that password is used to authenticate the user. If this fails, the authentication module returns failure without prompting the user for a password. This option has no effect if the authentication module is the first in the stack, or if no previous modules obtained the user's password. try_first_pass This option is similar to the use_first_pass option, except that if the previously obtained password fails, the user is prompted for another password. nullok Normally, keys with no passphrase are ignored for authentication purposes. If this option is set, keys with no passphrase will be taken into consideration, allowing the user to log in with a blank password. SSH Session Management Module The SSH session management component provides functions to initiate (pam_sm_open_session()) and terminate (pam_sm_close_session()) sessions. The pam_sm_open_session() function starts an SSH agent, passing it any private keys it decrypted during the authentication phase, and sets the environment variables the agent specifies. The pam_sm_close_session() function kills the previously started SSH agent by sending it a SIGTERM. The following options may be passed to the session management module: want_agent Start an agent even if no keys were decrypted during the authentication phase. FILES

The pam_ssh module was originally written by Andrew J. Korty <ajk@iu.edu>. The current implementation was developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.
