I have a problem where a user of ours is unable to tunnel
their ftp program (which is internal GoLive! software)
through ssh for a secure connection. I've even tried this
between two machines on the same subnet and it does not

This is what I do (note that I first disable the ftp server
on my own machine):

bash-2.05# ssh reznor.tcct.nmt.edu -l shippy -L21:reznor.tcct:21

successfully logs me in as shippy on reznor.

Then, on my machine in another window:

shippy@neptune:~> ncftp -ushippy localhost 21

NcFTP 3.0.3 (April 15, 2001) by Mike Gleason (ncftp@ncftp.com).
Connecting to

reznor FTP server (Version wu-2.6.2(1) Fri Nov 30 10:50:22 MST 2001) ready.
Logging in...

Password requested by for user "shippy".

      Password required for shippy.


User shippy logged in.
Logged in to localhost.

ncftp /u/shippy > put foo
connect failed: Transport endpoint is not connected.
Falling back to PORT instead of PASV mode.
put foo: PORT failed.

On reznor, I see:

chan_shutdown_read failed for #1/fd5 [i1 o128]: Transport endpoint is
not connected
