What do you mean with "master node" ? You can contribute with the UFO coin network leaving a ufo wallet online H24 and mapping the IP node address (your IP wallet address) thru the modem opening to the public the 9887 port. You need to create a config file "ufocoin.conf" (in 0.9.0 version) to complete the public node.
rpcuser=ufouser
rpcpassword=6bjlvC5KKSjVyig5
rpcallowip=127.0.0.1
gen=0
daemon=0
server=0
rpcport=9888
port=9887
rpcuser and rpcpassword must be my or i should leave it like in header example of this topic? or i just need change ip thats all?
