control board setup

finding boards

the easiest way for us to find new control boards is to search for them with nmap. new boards from merlin tend to be on the 192.168.1.0/24 subnet (and often 192.168.1.199). fortunately, the mac-mini is currently on this subnet, as well as being on the 192.168.2.0/24 subnet where we would like the boards to be.

so, first, plug the new board into the hub that is connected to the macmini. make sure only one new board is connected at a time, otherwise it will detect them both, which could be confusing.

once connected, do a scan of all hosts on the 192.168.1.0/24 subnet with nmap, as root:

nmap -S 192.168.1.17 -sP -PA99 192.168.1.0/24

the -S 192.168.1.17 is only because nmap gets confused by the fact that the mac-mini is on multiple subnets

which will give you output like this:

#nmap -S 192.168.1.17 -sP -PA99 192.168.1.0/24

WARNING:  If -S is being used to fake your source address, you may also have to use -e <iface> and -P0 .  If you are using it to specify your real source address, you can ignore this warning.

Host 192.168.1.100 appears to be up.
MAC Address: 00:0A:59:00:9E:F3 (HW server)
Nmap finished: 256 IP addresses (10 hosts up) scanned in 4.981 seconds

the MAC addresses are for the host mentioned in the line above. the boards should have MAC addresses in the 'HW server' class. so the address we are interested in here is 192.168.1.100.

script

there is now a script to configure a board given that you know it's current IP address.

following the example above, you would run the script like this:

sh board_setup.sh 192.168.1.100 192.168.2.107

with the second ip address replaced by one not already allocated in the table below.

manually

if things go haywire, you can try your luck with doing it manually. to do this you connect to port 99. hitting return gives you a display of the current setup. here is a sample output from a working board.
