sshd: Denied connection to local port

Hallöchen!

I'd like to know the reason for the sshd syslog message

Received request to connect to host 127.0.0.1 port 5000, but the request was denied.

(Trying to connect vie NXClient from a Windows machine.) An
extensive Google search didn't reveal much except for links to
openssh's source file where this log message is generated. Any
hints how to get rid of this barrier are highly appreciated.

Tschö,
Torsten.

Has a ListenAddress been specified in sshd_config?

No. sshd_config only contains:

Protocol 2
PermitRootLogin no
PasswordAuthentication no
X11Forwarding yes
Subsystem sftp /usr/lib/ssh/sftp-server

First, the remote nxclient logs in as user "nx", which works fine.
Then, it logs in as user "bronger". This works, too. If I don't
select "ssl encryption", even the third step (X login) is made
sucessfully because in connects to port 5000 directly.

However, I want everything in the ssh tunnel, so it has to connect
to port 5000 from local. It's strange: It works from outside but
not from the local machine. At least it seams so to me; I don't
understand the procedure fully though.

Tschö,
Torsten.

I guess try running the client and the server in debug mode, see what's
output.

Do you lock down your /etc/hosts.deny file (ALL: ALL)?
If you do, try allowing 127.0.0.1 in /etc/hosts.allow (ALL: 127.0.0.1).
