I was following the documentation provided in (https://www.gnu.org/software/hurd/hurd/subhurd.html) on how to setup networking using eth-multiplexer. On the final command (sudo ifup /dev/eth0m/0), the process bugs out (https://ibb.co/hZskkf4). Now I can't ssh into my hurd system using the terminal either (ssh demo@localhost -p 2222). Any advice on this?
