Networks

(we will go through the following commands from sergio)

To which networks is sergio connected right now?

ip a

Is the bootleg library reachable? (see all HUB ip address here)

ping 10.0.0.103

Who else is on the network right now?

nmap 10.0.0.*

And who else is on the eduroam (in the same subnet) right now?

nmap 145.24.152.*

We can see this because we are part of these LAN networks.

(LAN = local area network)

But how do you travel from one network to another within the WAN?

(WAN = wider area network, aka the internet)

traceroute zulip.xpub.nl

But how do we reach the hidden LAN/VPN 10.0.0.* network from the WAN?

ssh tunnelling!
