FYI, on WinXP, Zope 2.8 appears to use localhost no matter what ip-address is set to in zope.conf.  For example, after setting the nonsensical

ip-address 100.100.100.100

then starting Zope still displays

2004-10-15 10:18:44 INFO ZServer HTTP server started at Fri Oct 15 10:18:44 2004
        Hostname: localhost
        Port: 8080
2004-10-15 10:18:44 INFO ZServer FTP server started at Fri Oct 15 10:18:44 2004
        Hostname: localhost
        Port: 8021
2004-10-15 10:18:46 INFO Zope Ready to handle requests

In current 2.7 branch, the default looks very different:

2004-10-15T10:27:19 INFO(0) ZServer HTTP server started at Fri Oct 15 10:27:19 2004
        Hostname: FATLAP.reston01.va.comcast.net
        Port: 8080
------
2004-10-15T10:27:19 INFO(0) ZServer FTP server started at Fri Oct 15 10:27:19 2004
        Hostname: FATLAP
        Port: 8021

and setting

ip-address 100.100.100.100

in 2.7 branch yields an error:

"""
ZConfig.ConfigurationError: There was a problem starting a server of type "HTTPServer". This may mean that your
user does not have permission to bind to the port which the server is trying to use or the port may already be
in use by another application. (Can't assign requested address)
"""

Alas, the same two tests still fail on WinXP, in the same way, after your changes (at revision 28199).

Sorry, I'm not a network guy, and am not even sure what "Does Zope 2.8 use all IP addresses by default on Windows?" means.  I just dropped in here to report that some tests broke <wink>.

Don't know about Windows :-)
I added a check for sys.platform != 'win32'. Does Zope 2.8
use all IP addresses by default on Windows?

Don't know about Linux, but two tests fail on WinXP now:

I commited a workaround for the problem. Not a total clean
solution...at least no longer a stopper for the Zope 2.8 release.

I tracked this down to the bind() call in medusa.
bind(('localhost', 8080)) binds only to 127.0.0.1:8080.
If you pass '' as hostname then it binds to all interfaces.
I assume we must change the default hostname from
'localhost' to '' somewhere (I assume in lib/python/ZServer/datatypes.py)

Fred. Could you please look at that issue. This is the last
remaining showstopper for 2.8a1.
I did my own investigations but got stuck at some point.

Attaching a diff of the Zope.Startup.handlers and ZServer.datatypes code between the 2.7 branch and the HEAD.

I *think* that the change to 'preparep to use the new
'get_default_host_info' function is the culprit here.

Fred's checkin message for the transaction which added that change says:

 r24547 | fdrake | 2004-04-26 15:44:45 -0400 (Mon, 26 Apr 2004) | 4 lines

 Medusa wants the IP number, not the actual hostname, so give it that
 way.  We do more work up front, but this makes the pieces go together
 more cleanly in the end since expectations aren't fudged.

Fred, can you figure out why we don't bind to all interfaces anymore?

It seems like you have the same problem, but it just decides to connect only to 127.0.0.1, while in my case it decides to connect to another address. 

Just tested 2.7.3b1 and that works, so it's only only on the trunk.

Where there some changes lately on the SVN trunk?
The current checkout only binds to 127.0.0.1 but not to all
other IP addresses.

When no ip-address is specified in zope.conf, 127.0.0.1 seems not to be picked up. I can access Zope through the other IP-adress but not 127.0.0.1 or localhost. This worked with Zope 2.7.2.

If I set up an ip-address in zope.conf:
   ip-address 127.0.0.1
then 127.0.0.1 works, but of course not the other one.
