Networking · medium · solved in-browser (no VM needed) · 3 tiered hints
Write /home/player/setup-eth1.sh, a bash script that adds the address 10.0.5.10/24 to eth1 with `ip addr add`, brings the link up with `ip link set eth1 up`, and adds a default route via 10.0.5.1 with `ip route add default via`. It must start with a bash shebang. (Authored config, graded structurally — the engine isn't run here.)
