Er der nogen der kan hjælpe...

På computer2 (der opretter tunnelen) er der ikke noget problem at se 
idet tunnelen oprettes:

  ssh -p2222 -vv -R 2233:localhost:22 kristian@computer1
...
  debug1: remote forward success for: listen 2233, connect localhost:22
...
  Tunnel is up
  Press ctrl-c to close connection

Men når jeg så på computer1 forsøger at forbinde til tunnelen
(med: ssh -p2233 kn@localhost )
så siger computer2:

debug1: client_input_channel_open: ctype forwarded-tcpip rchan 2 win 
131072 max 32768
debug1: client_request_forwarded_tcpip: listen localhost port 2233, 
originator 127.0.0.1 port 43837
debug2: fd 7 setting O_NONBLOCK
debug2: fd 7 setting TCP_NODELAY
debug1: channel 1: new [127.0.0.1]
debug1: confirm forwarded-tcpip
debug1: channel 1: not connected: Connection refused
debug2: channel 1: zombie
debug2: channel 1: garbage collecting
debug1: channel 1: free: 127.0.0.1, nchannels 2

Hvorfor bliver denne "connection refused"?
