I'm simply not sharing anything on the W98 box. On the XP box where I 
need the sharing facility, I'm planning to add a loopback card with 
another ip (procedure found here: 
<http://www.blisstonia.com/eolson/notes/smboverssh.php>). Don't know 
yet how I will bind the forwarding to that network through cygwin, 
tough.

I'm quite sure the port forwarding works, though, because:

1. I tried to add verbosity, and it seems that everything is ok
	...
	debug1: Authentication succeeded (publickey).
	debug1: Local connections to LOCALHOST:139 forwarded to remote address 
myserver:139
	debug3: channel_setup_fwd_listener: type 2 wildcard 0 addr NULL
	debug1: Local forwarding listening on 127.0.0.1 port 139.
	debug2: fd 4 setting O_NONBLOCK
	debug3: fd 4 is O_NONBLOCK
	debug1: channel 0: new [port listener]
	...

2. My lmhosts entry for 'myserver' is set to 127.0.0.1 and I can't get 
the next step to work if I don't forward the port according to step 
1...

Any idea on what it's going on?

Thanks a log,
