Using library and citation services on the move

Library and citation services are subscription services, for which the institute is paying (considerable) fees. Access to these services are in principle restricted to network adresses within the institute.

To gain access from outside, without assistance from a system administrator (see the proxy method for that case), you need to establish a "tunnel" via a login service, such as the secure shell (SSH).

The tunnel method

The principle here is that you gain access by logging in with SSH and use a functionality within SSH to "tunnel" other requests, such as web browsing, through the established connction.

You need to make separate changes in the preferences of your web browser and your SSH program:

SSH client changes

For the www.ssh.com client (which is an excellent free client for academic users), you need to activate tunneling of HTTP services ("Edit" -> "Settings ..." -> "Tunneling").

Make the choices (examples):

 Dislay name: HTTP
        Type: TCP
 Listen port: 8080
 Destination: proxy.fys.ku.dk
  Dest. port: 3128

After making these changes, close the SSH window (not just the Settings), be sure to remember to use "Save Settings" from the "File" menu, open the window again and log in to a host from which access is allowed to that proxy (in this case for example johansen.fys.ku.dk).

Web browser changes

In the proxy preferences of your web browser, make the choices

	proxy host:  localhost
	proxy port:  8080       (same as above)
