Disabling mDNS

[mYnDstrEAm]

By running sudo lsof -i on Debian I found that TiddlyDesktop runs mDNS. Why is that and how to turn it off? It sends multicast mDNS packets from nw and /proc/self/exe processes (afaik the latter are symbolic links to the nw executable). Maybe it runs mDNS to enable TiddlyWiki access from other machines on the local network or sharing of ones TiddlyWiki with other people. Any details about that and the use of /proc/self/exe here?

I don't want to have the TiddlyWiki accessible from anywhere else than the local machine, would like to restrict network activity to what is needed and explicitly permitted, and could not find a setting to turn it off in the preferences.

TiddlyWiki 5 doesn't itself use mDNS, so it must be a dependency of nwjs. Looking at some issues there I suspect it might be something to do with the Chromecast functionality of Chrome. I intend to make an update to TiddlyDesktop soon and will investigate further.
