I have become very accustomed to SSH, it transpires. So much so that I was tweaking the network configuration of a system yesterday and worried that I might cut off my login session.
Then I remembered that there were *two* wires going over to the machine. I had connected up the null modem cable and configured a serial port login service at one end and my terminal emulator at the other.
Let's use that, then!
No amount of /etc/network/interfaces mucking about will break a null modem connection.
I think that I haven't remotely administered a system via a null modem local terminal this century, it is that long ago since I last did it. It has all been either SSH or some heavyweight #KVM/#ILO system.
