fabric observations

bizarre non default

env.use_ssh_config = True

http://stackoverflow.com/questions/3077281/pythons-fabric-connect-to-a-host-listed-ssh-config

non standard ports

Seems the port must be in the host string it is not good enough to get the port via the SSH config. Thus must do:

fab -H Z9:229 hostname

Rather than:

fab -H Z9 hostname

usage ideas

network graph checking

fabfile that invokes remote fabfiles that invokes further to test all ssh connections in network of nodes, pulling the results into rst format graphiz node diagram constructed in part on each node and collected back to the invoking node

to stop the recursion getting out of control, need to handle the originating node differently OR use a dated output file that is checked for before proceeding to call buddies
