So I don't have to change anything to miner.yourbtc.net ?
Yep right, you can use whateveryouwant.yourbtc.net or just yourbtc.net. The only important thing is to use Port 8999.
Hmm, as [mining|srv02].yourbtc.net and *.yourbtc.net resolv to different IPs you're doing some kind of port forwarding or proxying there.
For a transitional phase this is fine but in the long run you shouldn't do this as it
- undermines the pool/website separation (see above)
- adds a additional error source to the pool
- slows down the connection to the pool
- makes it unpredictable where users connect to (which might become a problem in the future).
Anyway the new server works like a charm! My efficiency raised up to ~99.6% and cgminer warnings ("Pool not providing work fast enough") dropped by ~50%. Great work, urstroyer!
