ccminer -a x17 -o stratum+tcp://mpos-pools.com:3602 -u USERNAME.1 -p PASSWORD
you have to create the worker on your account and after that you insert the name of the worker and the password. It is working...but average time for a block is over 4 hours....
No, it's actually been slowly deteriorating - I was getting a few errors but still mining to mpos-pool, but now it's nothing but
"Stratum connection failed: Failed to connect to mpos-pools.com port 3602: Connection refused"
edit: and of course as soon as I post this, the connection works
