SSH tunnel in Putty says "address already in use" but that's not true

I've configured a putty session from Lubuntu to a VPS on the Internet via a proxy server. The connection to the VPS is correctly established, but the tunnel isn't.

This is the tunnel configuration:

L1446 xx.xx.org:446

Before running putty:

$ netstat -na | grep 446
$ (No answer)

Whe I run putty, I get this log:

Event Log: Local port 1446 forwarding to xx.xx.org:446 failed. The address is already in use

But:

$ netstat -na | grep 446
$ (No answer)

So, I don't know where else to check. I would appreciate any help.

The error refers to local port (1446), not to the remote address/port.

Try to select another local port in PuTTY tunnel configuation.

2Thank you for your answer. I know the error refers to the local port; the "netstat -na | grep 446" was executed in the local machine. I tried other ports (my first try was 446, then 10446, but they all fail). I'm launching putty as gksudo putty in case it was a question with permissions, but... that fails too. – David – 2013-04-15T12:25:34.343
