Hi,

I'm a bit baffled by the following problem. If I attempt to forward to
remote ports via putty, it works just fine. If I attempt to do the
same via command line openssh, I get a failure. I'm not sure what
putty is doing that I'm not! I'd like to be able to establish this
tunnel from a mac so I need to use the command line ssh.

[I've search-and-replaced specifics with generics like my-ssh-host, my-
remote-server and my-username, but of course in the real test I used
the actual values!]

The following is what I'm trying via command line:

$ ssh -f -g -N -R7000:my-remote-server:7000 -R 7001:my-remote-server:
7001 my-username@my-ssh-host
my-username@my-ssh-host's password:
Warning: remote port forwarding failed for listen port 7000
Warning: remote port forwarding failed for listen port 7001

as you can see, the forwarding fails.

And yes, I'm closing the putty-established tunnels before attempting
to forward the same ports via command line ssh!

When I try it via putty, it works. Below is an export of the registry
key from my putty profile. Can anyone tell me what I'm doing wrong or
what the equivalent command line options to create the connection that
putty is creating?

Thanks!

oops, ignore that space between the -R and the 7001 -- that wasn't
there in the original command I tried!

and have you tried
$ ssh -f -g -N -R 7000:my-remote-server:7000 -R
7001:my-remote-server:7001 my-username@my-ssh-host

instead? (one line command)

Yep. That's what I had done originally. I guess it wrapped onto
multiple lines in my post, but the original attempt was definitely all
on one line. I just can't figure out what equivalent options putty is
sending that makes it work!

me@my-workstation ~
$ ssh -f -g -N -R 7000:remote-host:7000 -R 7001:remote-host:7001
me@ssh-host
me@ssh-host's password:
Warning: remote port forwarding failed for listen port 7000
