I setup the rpc details and my GPU started generating mhashes... but, how do I know if namecoind is actually working on solving blocks? If I run "namecoind.exe getinfo" I see "hashespersec : 0". My GPU is doing work though?
also, if a block is found.. do I need to wait 120 blocks? how do I know if I found a block?
You don't need "-server", this is automatically applied when running namecoind. Just like with bitcoin, the "hashespersec" will show zero if you use an external getwork based miner. Your miner should tell you if it is working or not (it'll show a hash rate and/or accepted blocks).
Yes, you need to wait 120 blocks when a block is found. Your miner will tell you when you found a block. You can use 'listtransactions' to see immature blocks and how many confirmations they've had.
for listtractions I get -
error: {"code";-32601,"message":"Method not found"}
I am using the Windows exe.
Do I need to list the account?
