Hi,
sorry, my bad!
On Ubuntu python's stdlib socket.gethostbyname return 127.0.1.1 NOT
127.0.0.1
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.gethostbyname(socket.gethostname())
'127.0.1.1'
It will cause the connect fail on Ubuntu, but Mac OS X can work normally
Python 2.7.8 (default, Aug 24 2014, 21:26:19)
[GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.40)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.gethostbyname(socket.gethostname())
'192.168.111.105'
I tried to bind(('0.0.0.0', port)) but it return 127.0.0.1 either Mac OS X
or Ubuntu.
Remote client (Snort machine side) can't connect to 127.0.0.1.
I also found another way to get host IP but need additional installs
package netifaces. (https://pypi.python.org/pypi/netifaces)
Or, maybe let someone config controller IP address in applications?
