[Python] Finding connected IP addresses

[Timothy Bolz]

Thanks Bob

I think nmap is nice.  I've been looking and reading trying to find out how to 
at least get my ip.

>>> import socket
>>> ip = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
>>> ip.connect(("1.1.1.1",1))
>>> print ip.getsockname()
('192.168.0.5', 32926)

I've read somewhere python keeps a socket open to do things like this.

I guess I could do a loop to check all the internal ip address.  

Well I did find something what I looking for But I think it would be nice in 
an IM who's on format.

I liked the above the best.

The above was a windows build but screenshots are nice.

Umit looks nice but too, almost what I want.
http://sourceforge.net/projects/umit
Umit runs in python too.

Trying to get Umit going.  I'm having problems.

Again Thanks

Tim
