| 3 | 1 | sph | This is more of a quick howto for those who are already somewhat familiar with SSH tunneling. For more detailed information about SSH tunneling you can check your SSH client's manpage. |
| 4 | 1 | sph | |
| 5 | 1 | sph | There are two ways to tunnel your client-core connection over SSH. You can either use static port forwarding or use a socks5 proxy. |

| 7 | 1 | sph | h2. Static port forwarding |
| 8 | 1 | sph | |
| 9 | 1 | sph | Forward local port 4242 to the correct on the core machine: |
| 10 | 1 | sph | |
| 11 | 1 | sph | > <pre>$ ssh -L 4242:localhost:4242 example.com</pre> |
| 12 | 1 | sph | |
| 13 | 1 | sph | The same can be achieved via PuTTY by entering _4242_ as source port and _localhost:4242_ as destination in the SSH > Tunnels tab. |
| 14 | 1 | sph | |
| 15 | 1 | sph | In the client simply connect to localhost, port 4242. |
| 16 | 1 | sph | |
| 17 | 1 | sph | h2. Socks 5 proxy |
| 18 | 1 | sph | |
| 19 | 4 | sph | Modern SSH clients like OpenSSH and PuTTY can also use dynamic port forwarding by turning itself into a socks proxy. Quassel can then set up a connection to the core using this proxy. |
| 20 | 1 | sph | |
| 21 | 1 | sph | > <pre>$ ssh -D 1080 example.com</pre> |
| 22 | 1 | sph | |
| 23 | 1 | sph | In PuTTY, you can select the _Dynamic_ option and then add _1080_ in the SSH > Tunnels tab. |
| 24 | 1 | sph | |
| 25 | 3 | sph | Now the client setup is a little bit more difficult since Qt 4.5 and earlier do not support hostname forwarding. You need to figure out the local IP address of the core because _127.0.0.1_ or _localhost_ will not work unfortunately. |
