After installed Raspberry Pi in your environment with Internet connection with my previous post, next step for Pi lover is how to configure your Pi so you can control it from anywhere you go. From the research by Google, I found there are two websites providing free service to remote access your Pi from anywhere through Internet.
1. Weaved Remot3.it
Note: Weaved has evolved to become remot3.it. Once Remot3.it process verfifed, I will update this part again. 1.1 Upgrade a Pi to remot3.it over a Weaved SSH connection
Use these instructions ONLY if you are connecting to the Pi over a Weaved ssh connection.Â
Add your Pi and all your Weaved services to remot3.it today
1.2 Upgrade your Pi to remot3.it from Weaved
Use these instructions ONLY when you have physical access to the Pi via a LAN connection (Wi-Fi or ethernet). Or use a USB (or bluetooth) keyboard+mouse and HDMI monitor.
Step 1 of 4
Open up a command line on your Pi using either a keyboard+HDMI monitor or an ssh connection over a Wi-Fi or ethernet LAN.
Step 2 of 4
Update the package list on your Pi so you will get the latest version of the weavedconnectd package
> sudo apt-get updateDownload and install the weavedconnectd deb package that includes support for remot3.it by entering the following command.
> sudo apt-get install weavedconnectdRun weavedinstaller from the command line.
sudo weavedinstallerUse the on-screen Sign In Menu (shown below) to Sign In to your remot3.it account by entering "1" at the prompt. Use your pre-existing Weaved account email and password to Sign In to www.remot3.it88.
Next, when prompted to enter a device name, give your Pi a device name (ex. my_Pi_001 ) as shown below. The device name entered will be displayed in the remot3.it portal. You can edit the device name later at any time. Type in a name and press Enter, then let the installer finish and return to the prompt. Then Exit the interactive menu installer by entering "4". (menu item 4).

2. Dataplicity
If your Raspberry Pi is connected to the internet, you can access it via Dataplicity from anywhere through Internet. You can even connect to devices behind firewalls without needing complex network configurations. Dataplicity connects using client-initiated HTTPS, so it's safe, encrypted and you don't need to make specific firewall exceptions. Dataplicity's homepage says only 60 seconds you can have your Pi to be ready for controlling from anywhere. Of course, it will take longer than 60 seconds but you will not wait more than 5 minutes. Here are all outputs with my test:

3. Raspberry Pi Dynamic IP DNS Update
3.1 install DDclient on Raspberry Pi
3.2 Configure /etc/ddclient.conf fileÂ
I am using Dynu free dynamic domain update service. Based on what I found the the suggested configuration file from Dynu website, I generated one for myself.

Last login: Sun Dec 4 22:43:54 2016 from 192.168.2.13 pi@raspberrypi ~ $ cd /etc pi@raspberrypi /etc $ sudo cat ddclient.conf daemon = 60 syslog=yes # Lheck every 60 seconds. mail=root # Mail all msgs to root. mail-failure=root # Mail failed update msgs to root. pid=/var/run/ddclient.pid # Record PID in file. use=web, web=checkip.dynu.com/, web-skip='IP Address' #Get ip from server. server=api.dynu.com # IP update server. protocol=dyndns2 login=jonnet # Your username. password=12345678 # Password or MD5 of password. 51sec.DYNU.COM # List one or more hostnames one on each line. 91sec.dynu.com #MYDOMAIN.COM pi@raspberrypi /etc $
3.3 Run ddclient as a daemon
Since we don't just want the IP address to update once, we still need to set up ddclient to run as a daemon so it can check for a change of IP address periodically and notify the dynamic DNS provider if necessary.
To start the daemon we need to open another configuration file,Â
/etc/default/ddclient and set:
You will notice there is aÂ
daemon_interval parameter there too, I think the default value of 300 seconds (5 minutes) is reasonable, so I didn't change it.
Save and close the file, and then run:
to start the daemon, and:
to check its status.
ddclient keeps a cache of your IP address, and it will only update the record with your dynamic DNS provider if your IP address hasn't changed. Since some ISPs seem to only allocate new IP addresses when the modem is power cycled, and some dynamic DNS providers will time out if you don't update the record in a while, there is one thing left to do - we need to add a cron job to force an update weekly, just in case.
Choose whether you want to force an update daily or weekly, and then create a file called ddclient in the relevant directory, e.g.Â
/etc/cron.daily or /etc/cron.weekly:
Fill in this information:
Then make the script executable:
Done :)
Note: For how to get your public ip address from Linux Command line
usingÂ
curl or wget  extract the information from public site:curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//'
orÂ
wget http://ipinfo.io/ip -qO -
