Run a script at remote server without ssh password
Hello,
What I want to do is to run a file on remote server by running a script at localhost but script should not ask ssh password of my remote server when script is executed.

Scenario1:
To copy files from server2 to data server:
Code:
$ scp -r root@server2_ip:/var/www/html/*.* /var/

When I enter above code, it asks for my server2 ssh password

Scenario2:
I want to run a script existing in server1 and it will be run at server2
Code:
$ ssh ./ex.bash server2_ip "bash -s -- '<--time bye>' '<end>'"

When I enter above code in terminal, it asks for my servers ssh password.

I want to run ssh or scp commands from a script via crontab, but don't know how the script will remember remote server's ssh password.

I tried different variations but no result.
Code:
root:sshpass@server2_ip:/path
root@sshpass:server2_ip:/path

How may I do this?

Thanks in advance
Boris

NAME

       asadmin-list-instances, list-instances - lists all the instances in the server

SYNOPSIS

       list-instances  [--user	admin_user]  [--password  admin_password]  [--host localhost] [--port 4848] [--domain domain_name] [--local=false]
       [--passwordfile filename] [--secure|-s]

       Use the list-instances to list all the instance in the server. The list-instances command can be run both locally and  remotely.   To  list
       remote  instances,  the named administration server must be running on the hostname and port number specified. The user authenticates using
       the password identified for the administration server.

OPTIONS

       --user		       administrative user associated for the instanace.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       port number associated with the administrative host.

       --domain 	       name of the domain.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

       Example 1: Using list-instances in local mode

       asadmin> list-instances --domain1 --local
       admin-server running
       server1 running

       Where: the server1 and admin-server instances for the domain1 domain is listed.

       Example 2: Using list-instances in remote mode

       asadmin> list-instances --user admin --passwordfile passwords.txt --host localhost --port 4848
       server1 [mayank:80] running

       Where: the server1 instance associated with the specified user, passwords, host, and  port  number  specified  is  listed  for  the  remote
       machine.
