Why isn't bitcoind listening on its rpc port?

Question

I run

sudo netstat --ip -lpa | grep bitcoin

After starting the bitcoin daemon and all I get is the 8333 port and the connections with other peers.

But when I do the same but with | grep namecoin, I get the rpc port and everything else.

I'm not being able to make poolserverj to work because of that. Since it's not listening, poolserverj gives me a 404 response on the rpc port.

My bitcoin.conf:

server=1
rpcuser=xxx
rpcpassword=xxx
rpcport=8332
rpcallowip=*
gen=0
