From 11c5981793f4a9b23ebceaf0ac2efdd74187c192 Mon Sep 17 00:00:00 2001 From: Leonardo Brondani Schenkel Date: Fri, 16 Aug 2019 11:13:53 +0200 Subject: [PATCH] Use old IP address lookup logic as fallback (#275) On some machines, resolving the local hostname results in a loopback IP address (127.0.0.0/8). This breaks discovery. In these situations, fall back to the old IP address lookup logic that was removed on commit 790edb9. --- broadlink/__init__.py | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/broadlink/__init__.py b/broadlink/__init__.py index 151786878..8b08ffc5f 100644 --- a/broadlink/__init__.py +++ b/broadlink/__init__.py @@ -64,6 +64,10 @@ def gendevice(devtype, host, mac): def discover(timeout=None, local_ip_address=None): if local_ip_address is None: local_ip_address = socket.gethostbyname(socket.gethostname()) + if local_ip_address.startswith('127.'): + s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) + s.connect(('8.8.8.8', 53)) # connecting to a UDP address doesn't send packets + local_ip_address = s.getsockname()[0] address = local_ip_address.split('.') cs = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) cs.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
