Re: Password won't update

sudo passwd runs as the root (superuser, uid(0)) and will set it's password. passwd runs as the logged in user and will set it's password but you need the existing password to do that. sudo passwd someusernamehere will use superuser powers to set the password for someusernamehere without needing to ...

Re: How to send a byte through GPIO

How do I send a byte through the gpio pins? In parallel you need 9 pins. 8 for the data, 1 to go high on data ready. (Hence the reason why 7-bit ASCII was so popular for printing, that saved a bit and saved a wire.) In serial you need 1 or 2 pins (or more), with 2 pins 1 for the data, 1 clock bit t...

Re: no mac address at all

Do you have a Windows machine that works with your router/WiFi? (I'll assume you do since you're posting on this forum.)

Open a windows cmd window and enter ipconfig /all, paste the results of that here.

I use Win32DiskImager for all my Backups. Its fast and easy. Backups with DD on the RasPi are just too slow, especially when the web server has a 16GB SD card!

Re: Pin failure

I've no cable connected to the GPIO Those pins are died? Probably not. You get stray values if a pin is allowed to float without a pull-up or pull-down resistor. If you attach a wire to an open pin and use a finger on the other end you can get a signal. Pins only die when you send volts over 3V3 do...

What language do you think WiringPi is written in?
Why not use tried and tested code rather than developing your own?
Code re-use and pre-written libraries are the way of the world.

Re: Get started with Pi without any external hardware?

You can easily run headless.

You may need a HDMI monitor to get it set-up and get raspi-config run and the network configured. But once that's done running it without a monitor is easy. PuTTY is my preferred SSH client on windows. JuiceSSH is the one on my Android tablet.

Re: installing isc-dhcp-server

Your RPi isn't connected to your WiFi (and therefore isn't connected to the public Internet).
Or your subnet mask is incorrect.
Or your gateway / routing table is incorrect.
Your WiFi adapter has gone into power saving mode.
Or you cable isn't connected to a live port on your router/switch.
