This is another manifestation of https://github.com/elpatron68/fritzcap/issues/4

When capturing on a Fritz!Box 7360 v1 on a different address than fritz.box, I get this log:

# python fritzcap.py --capture_files -d --monitor_calls --box_name 192.168.124.23

The problem is this content:

# cat captures/2017-06-21/120747/capture_20170621120747.cap

The reason is that there are some hardcoded fritz.box references in the Python files:

# grep -r fritz\.box --include \*.py
fritzcap.py:    ext_args.add_argument('--box_name', default=None, metavar='host_or_IP', type=str, help='the host name or IP address of the FritzBox (Default:\'fritz.box\')')
fritzcap.py:                "box_name": "fritz.box",
core/capture_monitor.py:            conn_url = 'http://fritz.box/login_sid.lua'
core/capture_monitor.py:                conn_url = 'http://fritz.box/login_sid.lua?username=root&response=' + response_bf
