hey guys, on lesson 188 about network namespaces I’m getting the following when trying to ping the blue namespace from red:
$ sudo ip netns exec red ping 192.168.15.2
ping: connect: Network is unreachable
Thought I’d done everything right so far… anyone else had this error?
$ ip -n red arp
please share output
$ sudo ip -n red arp
Object "arp" is unknown, try "ip help".
$ sudo ip netns exec red arp
you need to confirm you have setup default gw and you are pinging from same network 192.168.15.x assuming your netmask is 255.255.255.0
