NodeConfig script we can use to change configuration of any number of nodes.


usage:

   ../telnet-loop.sh nodetable.csv nodeconfigscript

will connect to all nodes (one-by-one), listed in the nodetable.csv (mac-addresses, etc.) execute the nodeconfigscript _on the node.
It is using the telnet daemon running on the nodes to connect.

the variant ssh-loop.sh uses ssh to connect to the nodes -- use ssh keys to connect without having to enter passwords...
