All raspberry devices MAC addresses started with B8:27:EB.
So, on *nix systems, this can be accomplished by executing the following command:
sudo nmap -sP 192.168.1.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'
where 192.168.1.* will be your local network mask. You will get an answer like:
Nmap scan report for raspberrypi.localnetwork.lan (192.168.1....

If you're running MacOS or Linux, try this one:
$ arp -na | grep -i b8:27:eb
On windows, you can use:
arp -a | findstr b8-27-eb

If you want to login as root using SSH or WinSCP you need to edit the config of SSHD, do this:
Login, and edit this file: sudo nano /etc/ssh/sshd_config
Find this line: PermitRootLogin without-password
Edit: PermitRootLogin yes
Close and save file
reboot or restart sshd service using: /etc/init.d/ssh restart
Set a root password if there isn't one already: ...

The IDE (probably) isn't the right place to be looking at this from. The simplest solution is to work with shared filesystems of some sort.
For exporting from the Rapsberry Pi the easiest way to export to a Linux (or I think Mac) host is to use sshfs. You'll need to install that on the computer you want to work on (there are Debian/Ubuntu packages at least),...

To make the answer a little more explicit, here are all the steps I took to get it working:
On the raspberry pi
Install tightvnc server (designed to support lower bandwidth)
sudo apt-get install tightvncserver
Configure vnc desktop with screen resolution and color depth
vncserver :1 -geometry 800x600 -depth 24
On the mac
Enable the native vnc client ...

As @lenik's answer says, your TV needs to support CEC. I installed a compiled version of libcec which included the command line utility cec-client from SourceForge using the following commands:
wget http://sourceforge.net/projects/selfprogramming/files/libCEC.deb/libcec_2.1.0-1_armhf.deb/download -O libcec_2.1.0-1_armhf.deb
sudo dpkg -i libcec_2.1.0-...

later I found out another solution to make it work for Remmina 0.9.99.1. You can change the security authentication for the VNC server to be VNC Password instead of Unix password and create an admin user credentials so you can use it in the remote connection as the following:
On VNC Server side on Raspberry Pi 3
Go to the options on the VNC Server on ...

sudo sh -c "TERM=linux setterm -foreground black >/dev/tty0"
sudo sh -c "TERM=linux setterm -clear all >/dev/tty0"
This will change the font color to black, than clears the screen.
Or in a single line:
sudo sh -c "TERM=linux setterm -foreground black -clear all >/dev/tty0"
And set it back to normal:
sudo sh -c "TERM=linux setterm -foreground ...

A couple of things to try:
Are you able to ping the Raspberry Pi from the windows machine, open a command prompt and enter ping 192.168.0.198 (but with the IP address you are using for SSH), if you get replies the connection is good, if not there is a networking problem preventing SSH working
Did you set-up SSH using raspi-config, or did you set it up ...

Check to make sure your SSH config is set to listen on all interfaces.
This will ensure that if the system boots and only WiFi is available, it will listen on the WiFi interface. I suspect this is ok based on your above description, but it is worth checking anyway.
The other thing I would do is watch the boot process via a monitor (if possible, or via dmesg ...

I can switch my TV on using the following command:
irsend SEND_ONCE LG_AKB72915207 KEY_POWER
This is how I set it up.
Hardware Setup
I am using a Raspberry Pi P1 2011.12.
The bare Infrared LED connected to GPIO#18 and GND.

sudo apt-get install lirc -y
Update /etc/modules
sudo nano /etc/modules

omxplayer now has an option to set the background to black.
omxplayer -b
It works both on the terminal and in X.
This feature should be in the current version available in raspbian.

you need a TV set that supports CEC (Consumer Electronics Control) protocol over HDMI. it might be a good idea to consult your TV manual or company web site to find details regarding your particular case, also quick search for "TV_model + CEC" might give you a few pointers.
basically, if your TV set is made just a few years ago, there's a good chance you ...

If you want to use a GUI application for it, you can use Yakala tool (https://github.com/mozcelikors/yakala) for Debian/Ubuntu. This tool helps you not only search for available Type B and Type C networks, but also helps you to directly SSH into the network:
sudo add-apt-repository ppa:mozcelikors/yakala
sudo apt-get update
sudo apt-get install yakala

If you're using vino for the VNC portion of xrdp (rather than vnc4server), you could follow these instructions to enable session sharing:
Log in to your Pi and install the Vino Package
$ sudo apt-get install vino
Next Run X11
$ startx
Once that is done you can run the vino-preferences from the terminal.
$ vino-preferences
Configure it like you want ...

Someone already implemented a module for LIRC (http://aron.ws/projects/lirc_rpi/). Just connect the sensor to the gpio pins. lirc_rpi is already present in current raspbian builds. The only thing you need to take into account is that some IR-sensors don't work on 3.3volt.
Here a detailed explanation of how I added remote control to my pi (my orignal post at:...

What you would need to do is create a reverse SSH tunnel. You would have to configure the Pi to do this before you place it at the remote locations.
What happens is the Pi creates a connection from inside the network. With normal NAT that is considered safe and the connection is established and any data that comes back is routed to the correct IP.
Some ...

By default the raspberry's name is raspberrypi. You can just 'ping raspberrypi' and the ICMP echo reply gives you the IP address. It worked for me. Make sure though the DHCP server is reachable as the raspberry's NIC is by default in DHCP client mode. Otherwise the raspberry gets an APIPA address.

For your system-level watchdog, I was going to suggest building a hardware watchdog. There are connections on the RPi board (the P6 header) which you can short to reset the device. You could connect this to a countdown timer chip, and have your app regularly use the GPIO pins to reset the timer. If your app stopped working for too long, the countdown would ...

Ok I solved this problem by adjusting the display options in Raspi-config. Using the following:
sudo raspi-config
Advanced Options > Resolution > DMT Mode 85 1280x720

You can use VNC. It's is a graphical desktop sharing system to remotely control another computer.
If you have Raspbian Jessie or later, VNC Connect is pre-installed. To enable VNC:
Go to your Raspberry Pi > Open the application menu > Preferences > Raspberry Pi Configuration > tab Interfaces > Enable VNC
If not, install VNC server manually :
sudo apt-...

You have a few options.
PHP
As long as we have python and .NET we must also have PHP. And as long as you got a LAMP installed then this is pretty straightforward. Here is a example of PHP getting emails from GMAIL
PROS - More likely choice for anybody using Linux as there are many examples and libraries.
CONS - If you don't like PHP you wills still use it ...

You need to install x11vnc daemon on the linux distro with runs on Pi. Then run that command;
x11vnc -display :0 -usepw -noxdamage -ncache 10 -ncache_cr -listen IP_of_pi -allow allowed_ip_address
After ran the command, connect to pi with any VNC client.

If you want to do web development, Aptana Studio can directly edit through FTP, or SSH (SFTP).

The Problem seems to be the incomplete USB Descrioptors:
Couldn't open device, some information will be missing
Report Descriptors:
** UNAVAILABLE **
The Descriptor that could be read say that this is a Mouse.

And that there would be a Descriptor of 20 Bytes that describes the data format:

I would like to know if the reset pin is an okay method of starting the Pi assuming it was properly halted.
There isn't actually a pin, but there are two holes at P6 on the rev. 2 board (~1cm left of the HDMI jack) that if shorted together will reset the power. You can attach a switch to this.

You may want to use the usbnet driver (usbnet homepage) which allow you to map USB port as they were Ethernet port. Then you can route traffic through your USB port and therefore ssh your RPi by the mean of a regular USB cable.

TeamViewer cannot be used on the Raspberry Pi at this time. They do not have a build for it.
You can install a VNC server, and that would be your simplest option. You would have no issues connecting on your LAN, however if you wanted to connect remotely, you would need to set up port forwarding.
An alternative to port forwarding would be to use a NeoRouter ...

That file is not on RPI3 you are trying connect to, but on the computer where you are trying to connect FROM (Ubnutu?). Just run
ssh-keygen -f "/root/.ssh/known_hosts" -R 192.168.1.234
on your computer. Not on the Rpi.
