[SATLUG] SSH Forwarding Problem

[Tameika Reed]

You should look in your /etc/hosts.deny file.
Usually it is blocked in and placed in that file

Subject: [SATLUG] SSH Forwarding Problem



Maybe someone can help me figure this out.  I have three machines,
let's call them apple, banana and cherry.  Apple is my workstation,
banana is a box that I can SSH to, and cherry is only available from
banana.

If I run these commands everything works fine:

$ ssh -L 2022:cherry:22 banana
$ ssh localhost -p 2022

And I get immediately connected to cherry with no problem.

When I try to put these settings into my ~/.ssh/config file I get this
error on the client:
ssh_exchange_identification: Connection closed by remote host

And this error on the server:
channel 47: open failed: administratively prohibited: open failed

Here is a copy of my ~/.ssh/config file:

****************
Host banana
Hostname banana.full.domain.name
LocalForward 21031 cherry.full.domain.name:22

Host cherry
Hostname localhost
Port 21031
HostKeyAlias cherry
***************

What's really frustrating is that the config file works fine for some
hosts, but not for others.  There are about six problem hosts on my
network that are not allowing the local port forwarding.  Any
suggestions???
