OSError : Cannot assign requested address

[sylvainmetayer]

I've just installed gnomecast but when I launch it, I've got the following error :

Traceback (most recent call last):
  File "/usr/local/bin/gnomecast", line 11, in <module>
    load_entry_point('gnomecast==0.2.6', 'gui_scripts', 'gnomecast')()
  File "/usr/local/lib/python3.6/site-packages/gnomecast.py", line 719, in main
    caster = Gnomecast()
  File "/usr/local/lib/python3.6/site-packages/gnomecast.py", line 154, in __init__
    s.bind((self.ip, 0))
OSError: [Errno 99] Cannot assign requested address

Here is my environment details, if it can help :

(([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")] or [[(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]]) + [None])

could you tell me what this give you?

[sylvainmetayer]

Here is the result : ['82.216.111.26', None] (with the import of socket, it wasn't working otherwise)

[keredson]

What version of python? Do you have a local firewall running?

[sylvainmetayer]

Python 3.6
I've just switched from Debian to Fedora, and it seems that the firewall policy is quite different. I'll look into it.

[keredson]

can you do the following w/o the error?

    with contextlib.closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
      s.bind(('0.0.0.0', 0))

[sylvainmetayer]

I've disabled the firewall in fedora but still experience the same issue.
I've tried your code snippet and I've had no output, but no error.

Here is the result : ['82.216.111.26', None]

82? What does ifconfig show?

[keredson]

i switched the bind to the universal address for you. please try v0.2.11 to see if this is fixed. (prob. it will also error when the HTTP server is binding. i'd like to see the output for that.)

[sylvainmetayer]

Sorry about the delay.
I've just upgrade to v0.2.15 and it is now working ! Thanks a lot ! :)

[keredson]

awesome! thanks!

I'm having this issue in Fedora 33; with python3.9 and pretty much the same results when issuing the commands. I get my public IP instead of my local IP.

[renich]

I've fixed it by adding an entry to /etc/hosts. Basically,

10.0.86.99 mydesktop.local mydesktop

So that gnomecast can get the proper IP. Now, it gets the internal IP; not the public one.
