Any ideas what I've done (or not done)?
Solo mining is not profitable even at todays difficulty (around 110). To solo mine you should have at least 5% of the network hashrate, which is ~150MH/s. If you have hashrate lower than that you should join a pool to offset changing difficulty.
How do I change to stratum? The VTC profit calc said I should find a block about every 4-5 days with a diff of 120. I'm okay with that.
Please remember that this number is an avarage, this means you might also find a block in 10 min. You could, however, be trying to find a block for 10 years too but without succes. That's why i'd suggest to use a pool, just because you'll be getting payouts on a regular basis.
I aware that its probability. Just wanted to try solo.
Any ideas on how to fix my setup?
Wich .bat config are you using atm?
At the moment, none. My miner is running linux. My wallet is running on Windows. If it matters, I used telnet to confirm that all ports are open.
Hmm I really don't know anything about linux tbh. I'm sure Boris or someone else with linux will be around and he'll probably be able to answer your questions.
bump. Still looking for assistance on solo mining...
