what operating system are you on?
what client or software are you using to ftp?
do you have firewall software installed or are you behind one? perhaps it is blocking all traffic to that port
Turning the fw off doesn't always turn the engine off.
Turning the fw to 'allow all traffic' might work better.
Or, you could make a new rule (tiny was a rule based fw right?) to allow all traffic to ident port.
