Hello all,
I've just joined. I did a google search and your site came up,
I had a look and thought I'd like to become a member.

I'm from Ireland.

I've written a few scripts before, but this new task has me foxed.

I would like to figure out the best approach to achieving the following

A single script that does the following
login to machine a (I typically use putty to do this)
login to machine b (as above)
on machine_a run a command such as "service xxx stop; service xxx start"
on machine_a ps -ef | grep AppName to confirm the app started right
on machine_a run top, and grep for a process by name, and batch the cpu% usage result to a file ( I can do this already)

on machine_b cd to a specific directory
on machine_b run a script that points at machine_a

on machine_b, when the script finishes
machine_a will parse the result file, and confirm the average of the cpu% is less than a threshold

That's pretty much it.
The hard part I suppose would be the single script spawing scripts on two different machines and synchonising them?

Thanks for your help in advance!

The easiest approach from a scripting standpoint would be to use ssh to launch commands on the remote system. ssh user@host "command [options]"

Thanks for reply.

When I tried that
ssh root@XXX.XXX.XXX.XXX "ls -al"

it asked me for a password.

As I would like to automate the process by scripting, without having to type in passwords.

Are there alternative approaches.

Easy on Windows, but how do I do it on rhel4?

Is this a new question for the group?

How odd is that! I thought I started a new thread.
I've been posting to the internet for 15 years, never did that before!

Set up public key authentication for your account on the server. That should enable password-less login
