newbie needs help building Python 2.5 for Fedora Core 6

2007-02-24 Thread bobmon 
Hello, and please be gentle...

I'm trying to build Python 2.5 on my Fedora Core 6 installation.  I
think I've resolved most of my problems, but make test reports an
error for test_socket.py, shown below.

I suppose my FC6 installation is missing something, but I have no idea
what.  Any ideas, directions, pointers would be most appreciated.

OK, so this fails:

my_ip_addr = socket.gethostbyname(socket.gethostname())

Try it from the python command line.  This is what happens when I try it 
on FC6 w/ Python 2.5 (retyped, tho):

 import socket
 socket.gethostname()
'localhost.localdomain'
 socket.gethostbyname(_)
'127.0.0.1'

Okay, that was interesting...

Apparently there's a subtlety of /etc/hosts that affects this!
Originally it had this line:
127.0.0.1localhostlocalhost.localdomainfoobar
and I get this result for my machine (foobar.foodomain.com):

 import socket
 socket.gethostname()
'foobar.foodomain.com'
 socket.gethostbyname(_)
Traceback (most recent call last):
  File stdin, line 1, in module
socket.gaierror: (-2, 'Name or service not known')


 socket.gethostbyname('localhost')
'127.0.0.1'
 socket.gethostbyname('localhost.localdomain')
'127.0.0.1'


Whe I change /etc/hosts to this:
127.0.0.1foobarfoobar.foodomain.net
localhost.localdomain   localhost
Python is happy and I get;

 import socket
 socket.gethostname()
'foobar.foodomain.net'
 socket.gethostbyname(_)
'127.0.0.1'



So, problem fixed although I have no real understanding of what was
wrong or what's right now.
Only that gethostbyname() seems to be really sensitive to the format
of the /etc/hosts file.

Thank you, Tony Nelson.
