I have never used it.
I *have* used getpass.getpass(). Unfortunately, it doesn't have a
corresponding prompt and raw input variant so I've had to essentially
copy over getpass() code and modify that:
fd = os.open('/dev/tt
I want to run torture tests against an https server on domain A; I have
configured apache on the server to respond to a specific hostname ipaddress.
I don't want to torture the live server so I have set up an alternate instance
on a different ip address.
