Finding the IP address on a headless RPi with dynamic IP can be tricky.
This will create a text file containing all your IP info (LAN, Wifi, Public) and upload it to an FTP server (or website).
This is useful, for instance, for mobile use of your SVXLink.
Simply view your website on your laptop/PC to find your RPi's address and login.

	# Create a script that will create a text file with your RPi's IP addresses
sudo nano /etc/uploadip.sh
----------------------------------------------------------------------------------------------------------------------
#!/bin/bash
echo Creating and uploading IP addresses to website . . .
echo "RPi name.......: `hostname`
LAN IP Address.: `/sbin/ifconfig eth0 | /bin/grep "inet addr" | /usr/bin/cut -d ":" -f 2 | /usr/bin/cut -d " " -f 1`
Wifi IP Address: `/sbin/ifconfig wlan0 | /bin/grep "inet addr" | /usr/bin/cut -d ":" -f 2 | /usr/bin/cut -d " " -f 1`
WAN IP Address.: `wget -q -O - http://icanhazip.com/ | tail`

sudo curl -T /home/pi/`hostname`.txt ftp://ftp.yoursite.com/folder/ip/ --user username:password
----------------------------------------------------------------------------------------------------------------------

	# Make it executable
sudo chmod +x /etc/uploadip.sh

	# Make it executable at startup via cron. The script wouldn't run via the /etc/rc.local file for some reason
crontab -e
	
	# FOR --== LAN CONNECTIONS ONLY ==--, add the following text at the end of the crontab config:
	# The @reboot will run uploadip.sh upon any reboot
	# The */10 * * * * will run uploadip.sh every 10 minutes
----------------------------------------------------------------------------------------------------------------------
@reboot /etc/uploadip.sh
*/10 * * * * /etc/uploadip.sh
----------------------------------------------------------------------------------------------------------------------

	# FOR --== WIFI AND/OR LAN CONNECTIONS ==--, add the following text at the end of the crontab config:
	# The 'sleep 120' command gives 120 seconds for a Wifi connection to complete prior to running the script
----------------------------------------------------------------------------------------------------------------------
@reboot sleep 120 && /etc/uploadip.sh
----------------------------------------------------------------------------------------------------------------------

sudo reboot
