Hi, Summary: What I want is, for a Fedora 28 Server (Intel NUC) to always prefer using wired connection if available, and fallback on wifi; not just for outgoing connections but also when I do 'ssh chris@f28s.local'. There is one AP/router that serves both wired and wireless connections and both server and workstation.
Hi, maybe turn off wifi when wired is up using script from: https://wiki.archlinux.org/index.php/NetworkManager#Mounting_of_NFS_shares regards, Gabriel
Out of the box this doesn't happen. So first questions are: should it work out of the box? can it be made to work? and if so what do I need to modify to make it work as described? What I've learned so far: 1. nmclic c show <connection uuid> connection.autoconnect-priority should be higher on the preferred connection. https://developer.gnome.org/NetworkManager/stable/nm-settings.html So I've picked a value of 1 for wired and 0 for wifi. That should mean if I make an outgoing connection, it should always prefer wired. And yet 'netstat -natp' shows this is not true, sometimes it's using the wired path sometimes the wireless path, and I can't tell what the pattern is. If any. 2. If I 'scp <fileonworkstation> chris@f28s.local:/tmp' I more often than not get clearly wifi speeds (and a connection check confirms it's using the wifi ip), but sometimes it's wired. Again, I can't figure out the pattern. 3. If I disconnect the wired connection, yes everything is deterministically wifi haha. But if I connect wired back in, the first X connections (or maybe it's Y time) are always only wifi and not wired. If I restart avahi manually, it becomes wired. Sooooo that means avahi might be playing a role here, it has no way of defining preferred connection though that I can tell. But I don't know anything about multicast and whether it can specify more than one address for a host name, and with preference based on the NetworkManager connection priority? Thanks,
