Bluetooth pairing

I'm trying to pair beagleboard xM with mobile phone using bluetooth.
Board has Bluez4.
I could get output of following commands :
1.hcitool dev
2.hcitool scan
But when I try ' rfcomm connect hci0 <bdaddr> ' & put any pass-key,
it says 'connection refused'.
Is there any way to store default pass-key?
Or is there any other way to pair with device?
