sshd has no internal support to open and close listening addresses on its own, so I suspect you're wrong. Why don't you try the actual use case, which is changing addresses rather than an initial open. However, I haven't used ubuntu in at least eight years and have no way to help you. > Also, e. g.

Well, yah, but when you change networks you're also not listening to the network. This isn't a race, this is just expected behavior. Even if sshd did this on its own this would happen. And it isn't a "hack", this is exactly what ifup/down scripts are for. Perry -- Perry E.
