Tests are not running well on machine with multiple networks

[ralphlange]

When running the tests on a machine with multiple network interfaces, they produce a lot of warnings:

[warning] More than one channel with name 'valueOnly' detected, connected to: /127.0.0.1:5075, ignored: /192.168.56.1:5075
[warning] More than one channel with name 'valueOnly' detected, connected to: /127.0.0.1:5075, ignored: /10.14.32.46:5075

While this is not failing the tests, it would probably be better to run them with explicit network configuration, preferably on localhost to avoid external side effects.

Ping ... issue still exists. (Still annoying.)

Pong... I know, this issue hangs over me.
