ssh says Cannot listen to port: 6000

[Anthony Campbell <ac@acampbell.org.uk>]

I'm trying to connect via ssh to a remote server, with
 ssh -f  -L 6000:localhost:4499 campbell@91.204.208.39 -N
channel_setup_fwd_listener: cannot listen to port: 6000

When I enter the password I get:

bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 6000
Could not request local forwarding


I can't find port 6000 with netstat -a.

There has to something wrongly configured on this machine because on a
different one it does work. Any suggestions what to try next?



Anthony
