vCO to read a file and execute remote shell commands via ssh

Hi,

Currently i'm managing multiple linux and unix servers and I want to automate many of the activities which needs as follows:

1. vco work flow needs to read a file where multiple hostnames present, and do a password less ssh with each server one by one, and running multiple shell commands

and want to get the output in a web page format.

2. how to configure the work flow as above.

Thanks for your support.
