Had you create a bitcoin.conf file within your data dir?
Also make sure there's a line server=1 and rpcallowip=0.0.0.0 at bitcoin.conf
# bitcoin.conf configuration file. Lines beginning with # are comments.
# Network-related settings:
# Run on the test network instead of the real bitcoin network.
#testnet=1
# Connect via a socks4 proxy
#proxy=127.0.0.1:9050

## Quick Primer on addnode vs connect ##
## Let's say for instance you use addnode=4.2.2.4 ##
## addnode will connect you to and tell you about the ##
## nodes connected to 4.2.2.4. In addition it will tell ##
## the other nodes connected to it that you exist so ##
## they can connect to you. ##
## connect will not do the above when you 'connect' to it. ##
## It will *only* connect you to 4.2.2.4 and no one else.##
## ##
## So if you're behind a firewall, or have other problems ##
## finding nodes, add some using 'addnode'. ##
## ##
## If you want to stay private, use 'connect' to only ##
## connect to "trusted" nodes. ##
## ##
## If you run multiple nodes on a LAN, there's no need for ##
## all of them to open lots of connections. Instead ##
## 'connect' them all to one node that is port forwarded ##
## and has lots of connections. ##
## Thanks goes to [Noodle] on Freenode. ##
