Networks
(we will go through the following commands from sergio)
To which networks is sergio connected right now?
ip a
To which networks is the bootleg library connected right now?
eh... we don't know if we can't ssh in?
Are we sharing a network with the bootleg library?
yes! the HUB
Can we check if we can communicate with the bootleg library through this network? (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 right now? (in the same subnet)
nmap 145.24.152.*
We can make such a mapping because we are part of the same LAN network.
(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!
