Summary: Python socket library confused by IPV6 notation in /etc/host
Initial Comment:
Robert J.Berger <[EMAIL PROTECTED]> reported this on the gpsd-dev mailing list
of the GPSD project.
"Until I changed the line in /etc/hosts from:
::1 localhost.localdomain localhost
to:
127.0.0.1 localhost.localdomain localhost
the gps.py [library distributed by the GPSD project] would fail when trying to
open the socket connection to gpsd:
File "/usr/local/bin/spGps.py", line 198, in __init__
self.connect(host, port)
File "/usr/local/bin/spGps.py", line 237, in connect
raise socket.error, msg
socket.error: (111, 'Connection refused')
This is with Python 2.4.4 under Red Hat Linux, kernel version not reported.
Robert believes, and I concur, that this is not a GPSD bug. Rather, something
lower-level -- possibly the Python socket library, possibly some C library it
uses -- is having indigestion on the IPV6 notation.

host is 'localhost'

What's going on here is that gps.py is a Python client module for a local
daemon that monitors GPS devices on the host's serial and USB ports and
presents output on port 2947. While it is possible to use gps.py to
monitor a remote host, Berger wasn't doing that. The socket module threw
an error while attempting to connect to localhost.

Can you please report the values of "host" and "port" when that error is
raised?
