The .conf I have is principally the same for all Alt-TC.
So, for PPC is
rpcuser=someusername
rpcpassword=somerandompassword
rpcport=9902
daemon=1
with one exception; for PPC, I also have this line there too:
server=1
The server=1, allows me to then run a commandline
ppcoind walletpassphrase MyWalletUnlockPassword 9999999 true
and have the "unlocked for block minting only" message over the lock, which apparently in time will let the interest accrue.
I'm not sure you even need the rpcport, if you aren't looking to port-forward from your router more requests than the usual 8 connections.
Serious Proof of Work mining is not something I've tried, having been put off by recognising I haven't got the hardware for it. If you were to mine, then there are plenty of guides for that from pools looking for your contribution that would encourage use of the other options above. I think I've seen it suggest one of them is a count of the number of CPUs available for example but not needed or useful if you're just holding coins and spending them.
