Hello Lads!

Climbing the shell scripting learning curve, i am faced with yet another obstacle! Here's the challenge in front of me :

1) I have 15 servers in a cluster,all of them have the same config files by name : /home/apps/xrm/App_B.cfg

2) The developers change the entries in the config files as and when required, and this is done on all the servers in the cluster.They take a backup of the original backup config before modifying it. Something like this: App_B.cfg.021509

3) I am trying to come up with a script which can be run on any one of the servers in the cluster which can do a comparision between the new config file (modified) and the old backup and put the result in a log, it should do this on all the 15 servers without me having to run the script on all boxes :

Code:

Example : 

The server names are :bpon03,bpon04,bpon05...bpon15

I would like to run the script on bpon03, and ideally would like the result to be in a log :

diff_log.txt with results in it as :

bpon03 :

diff App_B.cfg App_B.cfg.021509

xxx..xxx..

bpon04:

diff App_B.cfg App_B.cfg.021509

xxx..xxx..


bpon05:

diff App_B.cfg App_B.cfg.021509

xxx...xxxxx

and so on.

I know this must sound pretty silly for the experts here, but i am unable to come up with a solution with my very elementary scripting skills. Help would be greatly appreciated, and oh, the SSH keys are shared on all the servers,so thats not a problem. Thanks.
