Executing the script in Remote System

[arul_anand_2000]

Hi all,

I am trying to write a script which login to a remote machine and executes some command, wait till they are executed and continue processing the current script. I am not able to do this.

#This is the way i tried

if [#1 eq qa] ; then

sudo su xyz@ax01.xyz.com

cd /test/script

./runtheScript


fi

But when i try to execute the above script. It gives me an error that the script is not found. Also how could i sepecify the password for the xyz user so that he could log on sucessfully. I also want to know whether the command executing in the remote is finished? Can anyone help me in writing the script. Thanks in Advance.

Regards,
Arul.

have you considered kermit?

the communications package (from Columbia University) has a very
powerful scripting language designed precisely to automate such
doings as you suggest: logging in remotely, giving passwords,
running programs remotely, downloading the results &c

for linux, you want "C-kermit"

You can use "expect" to do what you want.
You will probably have to install it first:

yum install expect

or

apt-get install expect

depending on your distro.

However, a better way would be to setup SSH server and use public key authentication as Thrillhouse suggested here

Thanks a lot. Will try it out.

As noted, I believe SSH is the ideal solution. And using keychain allows you to only type in your passphrase once per login.

Currently, I routinely execute commands like this:

ssh webhost 'cd public_html; ls -l'

I also have entries in my ~/.ssh/config file so ssh knows what username to use on the remote host.
