Title:
Shared Connection gets 10.42.0.X IP addresses even if those are taken
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
When you choose "Shared to other computers" in network-manager to
create a network, the IP addresses are always 10.42.0.X. This is bad
enough, but it doesn't check if those addresses are already in use on
another interface, blowing up both networks and messing up routes.
A fix would be to un-hardcode the addresses, but even warning/stopping
the user from creating two networks with the same IPs would be better
than the status quo.
(In my setup one Ubuntu computer shares its network on a wired
connection. Another Ubuntu computer tries to share that connection via
WiFi. I'm not sure whether Network Manager warns if both the networks
are created on the same computer.)
