[benhylau]

Some commands for finding radios and proxying web interface:

sudo arp-scan -l
sudo arp-scan -l --interface=en5
ip neigh
ip -6 neigh
arp -a
socat tcp-listen:8000,reuseaddr,fork tcp:192.168.88.1:80

To configure managed switch

• Connect computer to one of Port 1 to 4 and set static IP 192.168.0.100
• Access http://192.168.0.239 with password password

To configure access point radios

• SSH into espressobin
• Run ip neigh or nmap -sn 10.nodeid.0.0/16 on the LAN
• socat
• Connect to IP on browser of computer

To configure ptp mesh radios

• SSH into espressobin
• Delete the routes with ip route del 192.168.88.0/24 dev wan.x except the one to radio you want to access
• socat
• Connect to IP on browser of computer

We discovered some ways to do this, but they are usually specific to the setup due to IP conflicts of some radios. I'll leave the draft notes here and mark this as future work.
