# Note that Novell ZENworks Network Access Control uses a
restricted Python socket
# library that doesn't allow connections to arbitrary
# hosts.
Normally, the first element of the tuple passed
# to socket.connect() is the IP or hostname; in SA, you
# must pass the Session object form which the socket
# object will get the target host IP/name.
