no-ip and openSUSE Raspberry Pi

We've seen how to install openSUSE image on the SD card.
Next step is to be sure that we can have access from outside our house (since most of the times, Raspberry Pi is located at home).
To do that we use Dynamic DNS services. A free service (so far) is No-IP. Most of the routers support it. You can use your router's service. But what if you want 2 different host names on the same IP? Let's say you have different ARM boards on the same router or you have a server etc.

1. First of all, install the needed programs to build the service (same as I did with ZNC)

zypper in gcc-c++ gcc git libopenssl-devel make nano

2. Then

mkdir noip

cd noip

3. Download the program


and decompress it

tar vzxf noip-duc-linux.tar.gz

4. Go to the directory

cd noip-2.1.9-1

5. Compile and install

make

make install

While it install’s the software you will prompted to enter the username & password. Once that is done it will ask you teh refresh interval … leave it.. to have the default value. You are required to answer some more questions … just ans NO an d you should be good to go.

6. Start the client

/usr/local/bin/noip2

To check if the service is running, use the command:

/usr/local/bin/noip2 -S

and the results should be like

1 noip2 process active.

Process 1516, started as noip2, (version 2.1.9)
Using configuration from /usr/local/etc/no-ip2.conf
Last IP Address set EXTERNAL IP
Account USERNAME
configured for:
host HOSTNAME
Updating every 30 minutes via /dev/eth0 with NAT enabled.


Auto start the client on reboot

But what if you reboot? You want to start the client everytime you reboot. This can be done with systemd.

1. Create the service file.

nano /usr/lib/systemd/system/noip.service

2. Add the following content.

[Unit]
Description=No-IP Dynamic DNS Update Client
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/noip2

[Install]
WantedBy=multi-user.target

3. Start the service

systemctl start noip.service

and enable the service

systemctl enable noip.service
