I have one ethernet wired Pi here and one wireless connected Pi. When I run nbtscan on the wired one it finds all computers on the network, wired or wireless (including itself) apart from the wireless Pi. When I run nbtscan on the wireless Pi it finds all computers on the net wired or wireless apart from itself.
I did think it was possibly due to both computers having the same hostname so I edited /etc/hostname on the wireless Pi and changed the name and still the issue persists.
I can ping it, ssh into it, access shared drives connected to it but still nbtscan fails to see it. It will only ever become a real problem if it's IP address ever changes as it is now headless and without the scanner seeing it it may be a bit tricky.
I think it's very much a software issue as it was fine until I did a new Raspbian image for it recently but I really have no clue what may be wrong.
Can anybody shed any light please?
