Cyberduck is not connecting to iPhone to SSH=[ help

Im trying to ssh into my iphone to delete some files that arent working right.
But Im using cyberduck, and ive put im pretty sure everything that im supposed to.

server= my ip address of iphone
port= 22
username= root
password= alpine

But when I try to connect it say," I/O Error: Connection Failed"

I've read other forums on this and I don't know what else to do=[

Please help try to walk me through this.

Also Any other things you might what to know is that my iPhone 3G is the 3.1.2. And no I do not have auto-lock on.

Disable ANY type of firewall or anything, turn it off and then reboot. It should work for you then.
