- Yet another solution is to install Cygwin on your Windows machine. It has both ssh client and X11 server (be sure to install the corresponding packages). Keep in mind that many X11 installations forbid untrusted X forwarding. Perhaps the simplest way around this is to use -Y option in ssh. Ssh -Y user@server xclock.

I am trying to use my server as a 'proxy' with ssh. However, setting up tunneling with ssh -D localhost:8000 user@myserver does not work. I tested this on various machines with ssh and putty - It. – Skaperen Sep 15 '12 at 19:26. Juno editor 2 3 35. Answered Jul 25 '14 at 11:50. 151 1 1 silver badge 3 3 bronze badges.
Ssh Tunnel 15 11.5
It is possible to use SSH to encrypt the network connection between clients and a PostgreSQL server. Done properly, this provides an adequately secure network connection, even for non-SSL-capable clients.
First make sure that an SSH server is running properly on the same machine as the PostgreSQL server and that you can log in using
ssh
as some user. Then you can establish a secure tunnel with a command like this from the client machine:Ssh Tunnel 15 111
The first number in the
-L
argument, 63333, is the port number of your end of the tunnel; it can be any unused port. (IANA reserves ports 49152 through 65535 for private use.) The second number, 5432, is the remote end of the tunnel: the port number your server is using. The name or IP address between the port numbers is the host with the database server you are going to connect to, as seen from the host you are logging in to, which is foo.com
in this example. In order to connect to the database server using this tunnel, you connect to port 63333 on the local machine:To the database server it will then look as though you are really user
joe
on host foo.com
connecting to localhost
in that context, and it will use whatever authentication procedure was configured for connections from this user and host. Note that the server will not think the connection is SSL-encrypted, since in fact it is not encrypted between the SSH server and the PostgreSQL server. This should not pose any extra security risk as long as they are on the same machine.In order for the tunnel setup to succeed you must be allowed to connect via
ssh
as [email protected]
, just as if you had attempted to use ssh
to create a terminal session.You could also have set up the port forwarding as
but then the database server will see the connection as coming in on its
foo.com
interface, which is not opened by the default setting listen_addresses = 'localhost'
. This is usually not what you want. My medical 2 5.Ssh Tunnel 15 110

If you have to “hop” to the database server via some login host, one possible setup could look like this:
Note that this way the connection from
shell.foo.com
to db.foo.com
will not be encrypted by the SSH tunnel. SSH offers quite a few configuration possibilities when the network is restricted in various ways. Please refer to the SSH documentation for details.Tip

Several other applications exist that can provide secure tunnels using a procedure similar in concept to the one just described.
