NO-IP on Centos 6

Hi all, we're about to learn how to set NO-IP on our Centos 6, first of all you'll need a no-ip account, so go to http://www.no-ip.com/ , create an account and then...
1.- Go to your account settings.

2.- Click on "Add a host".

3.- In the next form: "Hostname information" you'll need to fill in these mandatory fields:
    hostname: your desired hostname i.e.
        midominio + no-ip.org
    Ip adress: in this field you need to put your public IP, if you don't know what is your public IP, go to  this site http://www.whatismyip.com/

4.- This step is VERY IMPORTANT:
    Ir order to get access to your server from the public side, you'll need to open the necessary ports on your modem, go to your access point settings and edit the firewall rules or give access to your server machine on the correct ports, I mean if you're running a web server, then you'll need to address the port 80 of your modem to your ip server:

On the above example I gave access on the porst 22 and 80, because I'm using SSH and HTTPD.

5.- Now go for a beer.


6.- The rest is easy, you only need to do this on you terminal as root:
 cd /usr/loca/src
wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
tar xzf no-ip-duc-linux.tar.gz
cd no-ip-2.1.9
make
make install

7.- Eventually the binary will ask you for your no-ip user, no-ip passwd  and the minutes to refresh, the default for this last question is 30 minutes, so set your refresh time to 10 minutes if you want to.

8.- The result of the previous step will be a conf file, now you need to start the process, so go to your terminal and type:
./noip2

9.-  You can check if the process is running by doing:
ps -ef | grep noip2

10.- It is almost done, be patient only 1 more step, in order to get noip working everytime you reboot the server you'll need to add this line to your "rc.local" file:


whereis noip2
/usr/local/bin/noip2
echo '/usr/local/bin/noip2' >> /etc/rc.local

11.- Go for another beer and enjoy your new free public domain.

12.- Additional notes:
Some other options with noip2
noip2 Execute the binary
noip2 -S Shows the current status
noip2 -C to configure the client
noip2 -K This instruction kills the current process
