Does this sound correct now? I just put the below into the URL and nothing in Worker and Password?
cgminer -o stratum+tcp://solo.ckpool.org:3333 -u 1JuHMs8FZTzazq7B9B9Eg6oYpSQ9ADSTL9.0 -p x
Getting Socket connect failed: Connection refused error. Bloody thing.
I don't want to sound mean, but you mentioned that S17 is your first gear but you can't even set up the pool details, maybe get a cheaper gear to play with first?
anyway, to make it easier for you, here is exactly how to do it.
