static-upnp's Introduction

Static-UPnP

Static UPnP responds to upnp search requests with statically configured responses. This can be usefull to make devices available on other subnets, or to make devices available that are not responding to search requests.

Installation

git clone https://github.com/nigelb/Static-UPnP.git
cd Static-UPnP
pip install .

Or if you want static_upnp to automatically get the IP addresses to bind to from your network interfaces:

pip install .[interfaces]

Examples

Chromecast

This example demonstrates how to make a chrome cast available on another subnet. This demonstration assumes that the Chromecast's IP address is able to be determined by resolving the Chromecast hostname.

cd Static-UPnP
static_upnp --config-dir examples/Chromecast

If the Chromecast's IP address cannot be resolved you can set it by changing examples/Chromecast/StaticUPnP_StaticServices.py line 60. For example if the Chromecast's IP address is 10.0.0.20 then change line 60 from:

chromecast_ip = socket.gethostbyname_ex("Chromecast")[2][0]

to:

chromecast_ip = "10.0.0.20"

static-upnp's Issues

youtube works but Netflix does not

Nigel,
I am using you you deamon.
Works great for youtube on iOS, Android and chrome browser.
The Android and the iOS Netflix app do not work. Does not even show the cast icon.
Netflix works well on chrome, though!
Is this a known issue?
thanks,
Leo

CONFIG NOTE: OpenWRT + Chromecast

I had five issues with the setup and config.

  1. I had to install python with "opkg install python"

  2. I had to manually download, unpack, move to my router (using sftp) and install (using ssh) https://pypi.python.org/simple/schedule/ and https://pypi.python.org/simple/pyip/ with "python setup.py install"

  3. To have it run automatically is used this in me "/etc/rc.local" file:
    "python /root/Static-UPnP/static_upnp/static.py --config-dir /root/Static-UPnP/examples/Chromecast/ &"

  4. The group in OpenWRT is "nogroup" not "nobody". change here https://github.com/nigelb/Static-UPnP/blob/master/examples/Chromecast/StaticUPnP_Permissions.py#L19

  5. The router needs to accept 239.255.255.250 traffic. So I had to add a static route to "239.255.255.250" mask "255.255.255.255" on the interface without the Chromecast.

I hope this helps someone else figure it all out.

You can also replace this line https://github.com/nigelb/Static-UPnP/blob/master/examples/Chromecast/StaticUPnP_StaticServices.py#L61 with the static ip address of your chromecast if you can't set dns name resolution for "Chromecast"

It works perfectly though. I have a chromecast available on two separate subnets.

Not working for current version of chromecast

I've set up the flowering configuration
10.0.10.x/24 (WLAN) -> Smartphones, Clients
10.0.12.x/24 (WLAN_MEDIA) -> Chromecast

10.0.12.11 (IP of the Chromecast)

The Chromecast does not appear in the App. For example YouTube.
If i connect to the same wifi (WLAN), the button appears.

Checked the firewall, no traffic between the smartphone and or chromecast is blocked.

Can you see the problem?

Does not work when an interface has multiple IP addresses

I have a linux box as my router; it sits under a comcast modem/router - but all devices are under the linux box. eno1 is the 'external' nic; enp2s0 is the internal. There are a bunch of static ips assigned for the internal nic for each subnet.

This seyup however does not seem to be supported bby static_upnp, attempting to reregister multicast fails with address in use. (I added the 'Attempting to reregister' log line at the beginning of the loop that has ''Reregistering multicast'):

2021-12-27 21:37:40,956 INFO    UPnPServiceResponder util.py:setup_sockets:82 - Attempting to regester multicast for: 239.255.255.250: 10.1.1.1
Traceback (most recent call last):

    multi_sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)
OSError: [Errno 98] Address already in use

I don't know if my setup is weird and wrong and I should do something different; or if there is a way to hack around this to make it work...
