1. OpenSSH client - port forwarding
   connect to DSpace server and forward its port 8080 to localhost (machine we're connecting from) port 1234

   Code Block
   ssh -L 1234:127.0.0.1:8080 mydspace.edu

   makes mydspace.edu:8080 accessible via localhost:1234 (type http://localhost:1234 in browser address bar); also opens ssh shell
   exit ssh to terminate port forwarding
   Alternatively:

   Code Block
   ssh -N -f -L 1234:127.0.0.1:8080 mydspace.edu

   run with -N and -f flags if you want ssh to go to background
   kill the ssh process to terminate port forwarding

2. Putty PuTTY client - port forwarding
   The same with PuttyLocal port forwarding:

   Code Block
   Connection - SSH - Tunnels Source port: 80801234 Destination: localhost:12348080 Local Auto Add

   Once you're connected in PuTTY, visit http://localhost:1234/solr/ and you should see Solr's web interface. No browser configuration is necessary.

   
   Dynamic port forwarding/SOCKS proxy*:

   Code Block
   Connection - SSH - Tunnels Source port: 1234 Dynamic Auto Add

   Once you're connected in PuTTY, you'll need to configure your browse to use localhost:1234 as a SOCKS proxy (and remove "localhost" and "127.0.0.1" from addresses to bypass this proxy - like in the next step)

3. OpenSSH client - SOCKS proxy
   connect to DSpace server and run a SOCKS proxy server on localhost port 1234; configure browser to use localhost:1234 as SOCKS proxy and remove "localhost" and "127.0.0.1" from addresses that bypass this proxy
   all browser requests now originate from dspace server (source IP is dspace server's IP) - dspace is the proxy server
   type http://localhost:8080in browser address bar - localhost here is the dspace server

   Code Block
   ssh -D 1234 mydspace.edu

*Note about Putty as SOCKS proxy - while it can be configured, it raises a security exception when Solr is accessed. If you figure this out, please add this method here.
