Chris,
I found the same problem when trying to connect to an
owserver by specifying
hostname:port. I have done two things to fix the problem.
1. Don't use the "ow" package, but use "ownet"
ownet.init('localhost:4304')
tree(ownet.Sensor('/'))
2. Fixed the ownet package to properly use the _server and
_port passed to init and to properly cast the port to an integer.
It seems this must be untested code. An alternate would be
to not use ownet's init and use something akin to:
tree(ownet.Sensor('/', 'localhost', 4304 )
specifying the host and port directly to the constructor.
I'm not a python god by any means, but here is my
fixed ownet.Sensor code
in ownet/__init.py__ replace
_port = pair[1]
with
_port = int(pair[1])
Then in class Sensor function __init__ replace
# setup the connection to use for connunication with the owsensor
server
if connection:
self._connection = connection
elif not server or not port:
global _server
global _port
if not _server or not _port:
raise exNotInitialized
else:
self._connection = Connection(server, port)
else:
self._connection = Connection(server, port)
with (note only one line changes -- the first call to Connection)
# setup the connection to use for connunication with the owsensor
server
if connection:
self._connection = connection
elif not server or not port:
global _server
global _port
if not _server or not _port:
raise exNotInitialized
else:
self._connection = Connection(_server, _port)
else:
self._connection = Connection(server, port)
Working for me, so far. I've not poked about here enough to know who
to send these as diffs to to fix the source in CVS. They are
(in my opinion) wrong in the current CVS version.
