How to get Crossbar.io host name?

Question

I write chat using crossbar.io. We have several nodes of chat. I need write statistics about each of nodes, that's why I need to get host name where specific node is run.

Is it possible get host name from component instance?

I use last version of crossbar/autobahn and python 3.4.

Expect get - 127.0.0.1 if I use local environment.

Just use the socket library:

import socket

hostname = socket.gethostname()

@AleksandrYarushevsky What do you mean by "wrong hostname" ? – Pierre Barre Apr 26 '16 at 20:21
Now I run on localhost and I got 172.17.0.1 instead of 127.0.0.1 – Oleksandr Yarushevskyi Apr 26 '16 at 20:32

In case of your machine has a resolvable hostname try with:

import socket socket.gethostbyname(socket.getfqdn())

Update. This is a more complete solution, should work fine with all OS:

import socket print [l for l in ([ip for ip in socket.gethostbyname_ex( socket.gethostname())[2] if not ip.startswith('127.')][:1], [[(s.connect(('8.8.8.8', 53)), s.getsockname()[0], s.close() ) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0]

The same result got 172.17.0.1 instead of 127.0.0.1 – Oleksandr Yarushevskyi Apr 27 '16 at 11:03 — Oleksandr Yarushevskyi, Apr 27 '16 at 11:03
