How To Install No-ip In CentOS

No-ip client; use to update/resolve a server with a dynamic IP.


  • Create a free no-ip account.  Log in to the no-ip website and create a host.
  • Install “Make” compiler program in preparation to compile the no-ip program.  You might also have to install the “GCC” compiler if “Make” compiler don’t work; I have both GCC and Make installed.  The following is the  commands to download &install them:

yum install gcc

yum install make

Now onto the easy step-by-step installation of no-ip client.  Run the following 6 commands from the terminal:

  1. mkdir noip && cd noip

  2. wget

  3. tar zvxf noip-duc-linux.tar.gz

  4. cd noip-2.1.9-1

  5. make

  6. make install

You will then need to answer the following prompts:

Please enter the login/email string for

(Email account that you used to set-up no-ip account from their website)

Please enter the password for user 

(Password that you used to login to no-ip website)

Please enter an update interval: [30] 30

(Increments in minutes that you want no-ip client to check if your router’s external dynamic IP address has changed and updates it accordingly.)

Do you wish to run something at successful update? [N] (y/N)

(Enter “N” here)

Now start no-ip client by running the following command:


Now have no-ip client start every time the computer reboot by issuing the following command:

echo ‘/usr/local/bin/noip2’ >> /etc/rc.local

More useful no-ip commands:

  • /usr/local/bin/noip2 -C                                       to configure noip client
  • /usr/local/bin/noip2 -S                                       to display info about running noip client
  • /usr/local/bin/noip2 -U                                       to set update intervals (in minutes)

    Thanks a lot for writing this.. Using your manual I got no-ip up and running. The problem I am now facing is that it wont automatically start on rebooting the system even though I used the command echo ‘/usr/local/bin/noip2′ >> /etc/rc.local

    Do I need to specifically make changes to some configuration file so that it starts up automatically each time the system reboots?

      Hello Ram. Apologize for the late reply, been busy this month. The following link is where I extracted the information from, My setup using this info appears to be working as stated. Out of curiosity, I will look revisit potential issue and post resolution if I find it. Thanks.

      I have confirmed again that setup works using, echo ‘/usr/local/bin/noip2′ >> /etc/rc.local (no-ip automatically startups for me.) The possible pitful maybe, if you reboot your system and then check if no-ip client is running by issuing the following command, /usr/local/bin/noip2 -S, it will come back with the following message, “Can’t locate configuration file /usr/local/etc/no-ip2.conf. (Try -c). Ending!” This does not mean that no-ip client did not start after reboot, it means that you have to be root to issue the command (/usr/local/bin/noip2 -S) to check status.
