+Name: netifaces
+Version: 0.5
+Summary: Portable network interface information.

+Description: netifaces provides a (hopefully portable-ish) way for Python programmers to
+        get access to a list of the network interfaces on the local machine, and to
+        obtain the addresses of those network interfaces.
+        
+        The package has been tested on Mac OS X, Windows XP, Windows Vista, Linux
+        and Solaris.  On Windows, it is currently not able to retrieve IPv6
+        addresses, owing to shortcomings of the Windows API.
+        
+        It should work on other UNIX-like systems provided they implement
+        either getifaddrs() or support the SIOCGIFxxx socket options, although the
+        data provided by the socket options is normally less complete.

+netifaces 0.4
+=============
+
+1. What is this?
+----------------
+
+It's been annoying me for some time that there's no easy way to get the
+address(es) of the machine's network interfaces from Python.  There is
+a good reason for this difficulty, which is that it is virtually impossible
+to do so in a portable manner.  However, it seems to me that there should
+be a package you can easy_install that will take care of working out the
+details of doing so on the machine you're using, then you can get on with
+writing Python code without concerning yourself with the nitty gritty of
+system-dependent low-level networking APIs.
+
+This package attempts to solve that problem.
+
+2. How do I use it?
+-------------------
+
+First you need to install it, which you can do by typing
+
+  tar xvzf netifaces-0.4.tar.gz
+  cd netifaces-0.4
+  python setup.py install
+
+Once that's done, you'll need to start Python and do something like the
+following:
+
+  >>> import netifaces
+
+Then if you enter
+
+  >>> netifaces.interfaces()
+  ['lo0', 'gif0', 'stf0', 'en0', 'en1', 'fw0']
+
+you'll see the list of interface identifiers for your machine.
+
+You can ask for the addresses of a particular interface by doing
+
+  >>> netifaces.ifaddresses('lo0')
+  {18: [{'addr': ''}], 2: [{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}], 30: [{'peer': '::1', 'netmask': 'ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff', 'addr': '::1'}, {'peer': '', 'netmask': 'ffff:ffff:ffff:ffff::', 'addr': 'fe80::1%lo0'}]}
+
+Hmmmm.  That result looks a bit cryptic; let's break it apart and explain
+what each piece means.  It returned a dictionary, so let's look there first:
+
+  { 18: [...], 2: [...], 30: [...] }
+
+Each of the numbers refers to a particular address family.  In this case, we
+have three address families listed; on my system, 18 is AF_LINK (which means
+the link layer interface, e.g. Ethernet), 2 is AF_INET (normal Internet
+addresses), and 30 is AF_INET6 (IPv6).
+
+But wait!  Don't use these numbers in your code.  The numeric values here are
+system dependent; fortunately, I thought of that when writing netifaces, so
+the module declares a range of values that you might need.  e.g.
+
+  >>> netifaces.AF_LINK
+  18
+
+Again, on your system, the number may be different.
+
+So, what we've established is that the dictionary that's returned has one
+entry for each address family for which this interface has an address.  Let's
+take a look at the AF_INET addresses now:
+
+  >>> addrs = netifaces.ifaddresses('lo0')
+  >>> addrs[netifaces.AF_INET]
+  [{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}]
+
+You might be wondering why this value is a list.  The reason is that it's
+possible for an interface to have more than one address, even within the
+same family.  I'll say that again: *you can have more than one address of
+the same type associated with each interface*.
+
+*Asking for "the" address of a particular interface doesn't make sense.*
+
+Right, so, we can see that this particular interface only has one address,
+and, because it's a loopback interface, it's point-to-point and therefore
+has a *peer* address rather than a broadcast address.
+
+Let's look at a more interesting interface.
+
+  >>> addrs = netifaces.ifaddresses('en0')
+  >>> addrs[netifaces.AF_INET]
+  [{'broadcast': '10.15.255.255', 'netmask': '255.240.0.0', 'addr': '10.0.1.4'}, {'broadcast': '192.168.0.255', 'addr': '192.168.0.47'}]
+
+This interface has two addresses (see, I told you...)  Both of them are
+regular IPv4 addresses, although in one case the netmask has been changed
+from its default.  The netmask *may not* appear on your system if it's set
+to the default for the address range.
+
+Because this interface isn't point-to-point, it also has broadcast addresses.
+
+Now, say we want, instead of the IP addresses, to get the MAC address; that
+is, the hardware address of the Ethernet adapter running this interface.  We
+can do
+
+  >>> addrs[netifaces.AF_LINK]
+  [{'addr': '00:12:34:56:78:9a'}]
+
+Note that this may not be available on platforms without getifaddrs(), unless
+they happen to implement SIOCGIFHWADDR.  Note also that you just get the
+address; it's unlikely that you'll see anything else with an AF_LINK address.
+Oh, and don't assume that all AF_LINK addresses are Ethernet; you might, for
+instance, be on a Mac, in which case:
+
+  >>> addrs = netifaces.ifaddresses('fw0')
+  >>> addrs[netifaces.AF_LINK]
+  [{'addr': '00:12:34:56:78:9a:bc:de'}]
+
+No, that isn't an exceptionally long Ethernet MAC address---it's a FireWire
+address.
+
+3. This is great!  What platforms does it work on?
+--------------------------------------------------
+
+Well, see, here's the thing.  It's been tested on Mac OS X, and it seems to
+work.  (OS X helpfully has some of the SIOCGIFxxx ioctl()s, which means that
+most of those have been tested too, the only glaring exception being the
+SIOCGIFHWADDR ioctl(), which OS X just doesn't have.)
+
+It should probably work on most of the other UNIX-like systems with relatively
+minor changes.  If you do have to change something, send it to me at
+<alastair AT alastairs-place.net> and I'll see if I can merge it in.
+
+It also works just fine on Windows, using the GetAdaptersInfo() function.
+Note, though, that on Windows it isn't possible (yet) to retrieve IPv6
+addresses.  I don't use Windows at the moment, so this isn't a priority for
+me.  If you know how to fix it, drop me a line and I'll consider adding any
+necessary code.
+
+4. What license is this under?

+Metadata-Version: 1.0
+Name: netifaces
+Version: 0.5
+Summary: Portable network interface information.
+Home-page: http://alastairs-place.net/netifaces
+Author: Alastair Houghton
+Author-email: alastair@alastairs-place.net
+License: MIT License
+Description: netifaces provides a (hopefully portable-ish) way for Python programmers to
+        get access to a list of the network interfaces on the local machine, and to
+        obtain the addresses of those network interfaces.
+        
+        The package has been tested on Mac OS X, Windows XP, Windows Vista, Linux
+        and Solaris.  On Windows, it is currently not able to retrieve IPv6
+        addresses, owing to shortcomings of the Windows API.
+        
+        It should work on other UNIX-like systems provided they implement
+        either getifaddrs() or support the SIOCGIFxxx socket options, although the
+        data provided by the socket options is normally less complete.

+netifaces provides a (hopefully portable-ish) way for Python programmers to
+get access to a list of the network interfaces on the local machine, and to
+obtain the addresses of those network interfaces.
+
+The package has been tested on Mac OS X, Windows XP, Windows Vista, Linux
+and Solaris.  On Windows, it is currently not able to retrieve IPv6
+addresses, owing to shortcomings of the Windows API.
+
+It should work on other UNIX-like systems provided they implement
+either getifaddrs() or support the SIOCGIFxxx socket options, although the
+data provided by the socket options is normally less complete.
