During the initial Debian setup, we are asked simple questions to configure network interfaces. I would like to know is there are some interactive (but something terminal-based, no X11) tools to do the same but after this initial installation.
For example I would like a tool to configure /etc/resolv.conf and /etc/network/interfaces at once. If not, one can for sure develop a tool like that in a few minutes. I am just curious and do not want to miss something that already exists, like a "dpkg-reconfigure something"
