My node solved a block... but it is not mining

[Shevek]

I've got greatly surprised when, in rutinary browse of blockchain.info, I saw the IP-address of my node as solver of a block!

My node is running bitcoind (ubuntu, 0.8.1) during last 2-3 days, but mining options are unplugged. RPC-port is protected by password and I don't direct my external miners to my node (much better use of them in pools...). The node is rightly opened to internet, not behind proxy nor NAT.

Of course I quickly checked if the reward was driven to one of the addressed of my wallet... not the case :-(

So, what happened!?

No, you saw the IP-address of your node as the first to relay that block (that's why it says: "Relayed By" on top).
It might be the same node that solved the block, but it doesn't have to be.

Blockchain.info only reports the IP address where it first saw the block. 

So

Miner ---> you ---> blockchain.info

Blockchain.info saw the block "relayed from you" doesn't mean you mined it.

Actually it could be this

Miner ---> another node ----> another node -----> another node -----> another node ----> another node ----> you ----> blockchain.info

Yeeeah!

Thanks!
