Good afternoon to all.
I have recently had a problem at a site. This site has three nodes up on the tower about 250ft. all on different frequencies. connected to thier end point nodes. These are backhaul nodes used to interconnect multiple counties. I have one node that gives me a link on the switch but I can't access it.
I started running Nmap against the node 10.0.0.0/8 but after 4 hours I just gave up.
Is there a script out there that will send out a crafted packet and give back an ip address or some other piece of data to identify it? something that can help me identify this node so I can fix it. I have tried a reboot without success. Since this site has multiple nodes all DHCP is off except for one node. Pulling this one node and plugging into my laptop does me no good as I will never get an IP address.
The only other option here is to climb the tower and that i'm not able to do right now.
Thank you

a 15 second hold resets it to "just flashed" state.
All this can be done from the ground.
If so, you don't need to disable DHCP on them.
1) you could set a static IP on your PC 10.x.x.x.x and connect with a CAT5 cable to see if you can talk to it.
2) if you hold the reset button on the bottom of your PoE adapter for 5 secs, it will re-enable DHCP, reset the password to hsmm, and restart the web server.
I'm not sure I understand the problem either, but if you're on an Ethernet to which all the nodes are connected, then you only have to dump the olsr routing broadcasts with a tool like tcpdump or wireshark to discover the IP addresses of all the Ubiquiti nodes. I've appended an example, done on Linux.
They'll be on VLAN2 but Linux easily handles vlans; in fact, tcpdump/wireshark seem to just show everything it sees, even if the traffic is tagged.
I think OSX also handles VLANs, but in a slightly different way. I haven't used Windows in well over a decade so I can't speak to it.
