You should edit claymore config file located in /home/ethos/ folder if i remember correctly...

There you need to add dcr pool an wall address...

Also i think you should add -mode 0

so something like this

-epool eu1.ethermine.org:4444
-ewal xxxxxxxxxx
-eworker xxxxx
-epsw x
-dpool stratum+tcp://dcr.suprnova.cc:2252
-dwal xxxxxxxxx
-dpsw x
-mode 0
