[bitfolk] ssh problem

I am in Spain at the moment and am unable to log into my Bitfolk vm.
I could log in with no problem from England so can a friend in Florida
and it works from Brazil. The people I am staying with could log in
from an internet cafe so I think the problem is the ISP who is ya.com
part of Orange.

This is what happens (using a Mac)

zaphod$ ssh -vvv -p 2222 swalk@???
OpenSSH_5.2p1, OpenSSL 0.9.7l 28 Sep 2006
debug1: Reading configuration data /etc/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to swalk.eu [85.119.82.47] port 2222.
debug1: Connection established.
debug1: identity file /Users/zaphod/.ssh/identity type -1
debug1: identity file /Users/zaphod/.ssh/id_rsa type -1
debug1: identity file /Users/zaphod/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host

Can anyone advise me on what the problem is, why an ISP might do
whatever it does to stop the connection or suggest some sort of work
around.

PS I know I should be using SSH with authentication key instead of
password but I have been a bit lazy getting around to it.
