Hi Rowland

I tried with smb.conf below and captured with tcpdump wlan1 in the 
phone, with nothing else than the phone and the camera attached, trying 
to use only smb1 (I don't worry about security because there is only the 
server and the camera on this wlan).
sudo tcpdump -c5000 -U -i wlan1 -net 192.168.94.0/24 -w 
path/tcpdumpStartSrvsmb1.pcap
in one terminal.
In another one I run smbd && sleep 3 && nmbd -p1137 -d3 && sudo ip -4 a
last command just to check wlan1 IP.
still nmbd won't show on ps -A|grep mbd

There is no packet from the server when it starts
After initial DHCP offer/ack and broadcast ARP probe + own IP 
announcements from camera it seems the camera is only speaking smb1 
ports 137 to 138 but not 135 neither 139 (NBNS unreplied registration 
broadcasts for NBNS(137) name and workgroup, then also unreplied 
BROWSER(138) Get Backup List Request broadcasts, then NBNS Name query 
NBTSTAT full of zeros to the phone IP, to which an ICMP reply comes back 
from the phone IP with content Destination unreachable (Port 
unreachable), all this twice
until I manually teach it the server/phone IP, then it can finally show 
the share list and prompts credentials then connects/transfers files 
over smb2 port 445 (DCERPC - SRVSVC - SMB)
