ssh android?

i just got an android htc,rooted it,downloaded connectbot for sshing but i can't use it.
I try to ssh to my netbook on the local network but nothing happens...i get "connection lost-host has disconnected".i'm using port 22.it's weird because i can use any computer to connect to my netbook but I can't connect via android.I want a way to ssh to my pc with my phone.What am i doing wrong?To tell the truth i'm confused.Any advice or documentation on this would be apreciated because i don't know anything about networking.thanks;-)

Do you have the correct key to connect?

like a public key?i think i don't...will i have to disable it somehow?
