| Answer CAPTCHA from server's IP
 | |
| ===============================
 | |
| 
 | |
| With a SSH tunnel we can send requests from server's IP and solve a CAPTCHA that
 | |
| blocks requests from this IP.  If your SearXNG instance is hosted at
 | |
| ``example.org`` and your login is ``user`` you can setup a proxy simply by
 | |
| :man:`ssh`:
 | |
| 
 | |
| .. code:: bash
 | |
| 
 | |
|    # SOCKS server: socks://127.0.0.1:8080
 | |
| 
 | |
|    $ ssh -q -N -D 8080 user@example.org
 | |
| 
 | |
| The ``socks://localhost:8080`` from above can be tested by:
 | |
| 
 | |
| .. tabs::
 | |
| 
 | |
|   .. group-tab:: server's IP
 | |
| 
 | |
|      .. code:: bash
 | |
| 
 | |
|         $ curl -x socks://127.0.0.1:8080 http://ipecho.net/plain
 | |
|         n.n.n.n
 | |
| 
 | |
|   .. group-tab:: desktop's IP
 | |
| 
 | |
|      .. code:: bash
 | |
| 
 | |
|         $ curl http://ipecho.net/plain
 | |
|         x.x.x.x
 | |
| 
 | |
| In the settings of the WEB browser open the *"Network Settings"* and setup a
 | |
| proxy on ``SOCKS5 127.0.0.1:8080`` (see screenshot below).  In the WEB browser
 | |
| check the IP from the server is used:
 | |
| 
 | |
| - http://ipecho.net/plain
 | |
| 
 | |
| Now open the search engine that blocks requests from your server's IP.  If you
 | |
| have `issues with the qwant engine
 | |
| <https://github.com/searxng/searxng/issues/2011#issuecomment-1553317619>`__,
 | |
| solve the CAPTCHA from `qwant.com <https://www.qwant.com/>`__.

| .. admonition:: :man:`ssh` manual:
 | |
| 
 | |
|    -D [bind_address:]port
 | |
|      Specifies a local “dynamic” application-level port forwarding.  This works
 | |
|      by allocating a socket to listen to port on the local side ..  Whenever a
 | |
|      connection is made to this port, the connection is forwarded over the
 | |
|      secure channel, and the application protocol is then used to determine
 | |
|      where to connect to from the remote machine .. ssh will act as a SOCKS
 | |
|      server ..
 | |
| 
 | |
|    -N
 | |
|       Do not execute a remote command.  This is useful for just forwarding ports.
