::

  ssh -A 1.2.3.4

To carry the ssh through ``sudo``::

  sudo -E -s

  ssh -l USER HOST | tee -a /path/to/file

``tee`` is a command which displays or pipes the output of a command and copies
it into a file or a variable.

``-a`` option appends the output to the end of file instead of writing over it.

Tunnel

In this example, our server is hosting a web site on port 80.  We want to
tunnel the HTTP requests to our local workstation (``localhost``) and browse
to the site on port ``8888``::

  ssh -N -L 8888:localhost:80 server

Browse to the site on http://localhost:8888/

Quit
====

`Close a hanging ssh session`_
