Can someone please explain why when using remote desktop to connect to a server running GNOME desktop (Rocky Linux 8.6), an internet connection is established to 8.43.85.3:443 (master1.openshift4.gnome.org) or 8.43.85.4:443(master2.openshift4.gnome.org) and how to prevent the call.
After a few seconds or couple the connection state changes from ESTABLISHED to CLOSE_WAIT.
[root@test ~]# netstat -atWn | grep 8.43.85
tcp 0 0 192.168.97.67:58388 8.43.85.4:443 CLOSE_WAIT
There must be a way to prevent an estabished connection in the first place. Why is gnome-shell making this connection and how do I stop it (even if it is supposedly for my good).
It’s probably either nmcheck.gnome.org (captive portal check, should only run if you first fail to connect to Rocky Linux’s captive portal checker), or else extensions.gnome.org (should only run if you have extensions installed, I think?).
The package name of the Extensions app in Fedora is gnome-extensions-app. Extension Manager is unpackaged so far, but either app could be installed via flatpak.
