This is what I´ve changed in 1bash:
COIN:"ZEN"
ZEN_WORKER:"My-new-created-worker"
ZEN_ADRESS:"Wallet-key"
ZEN_POOL:"zen.suprnova.cc"
ZEN_PORT:"3618"
Have not done anything else. What am I missing?
Your ZEN_ADDRESS (note the extra D) for suprnova should correspond to your login name, not an actual wallet address. The pool and the port are correct. The next thing to consider is that 3main will use "x" for you miner password. I am not sure if suprnova is a pool that allows anything for password or not but I just wanted to point it out.
You can also look at the logging to figure out what is happening using this command:
tail -f screenlog.0
This will show the output of the miner (and other things if REMOTE) as it tries to start and connect.
Hope this helps.
