How to Configure a Nagios Web Interface IP Address

Nagios is a software tool used for monitoring and managing Internet Protocol (IP) network servers, device performance and availability. While there are ways to configure automatic IP address assignment to a Nagios server, manually configuring a static IP address and subnet mask is best for Nagios server security and management.

Skill level:

Things you need

  • Linux-based Nagios server computer
  • IP address and subnet mask for the Nagios server

  1. 1

    Open a terminal console (command line) on the Linux computer if it runs a graphical user interface by default. Usually, the terminal program can be found in the "System" "Administration," or "Utilities" section of the programs menu (depending upon the Linux distribution installed on the computer).

  2. 2

    Type "sudo ifconfig eth 0 mask," replacing the "" with the IP address assigned to the computer and "" with the subnet mask of the network and then press the "Enter" key.

  3. 3

    Type "sudo ifconfig" and press the "Enter" key then view the output and confirm that the new IP address is configured on the system.

Tips and warnings

  • If you receive a "command not found" or similar error, then use "/sbin/ifconfig" in place of just "ifconfig" when following the procedure. Also try removing the "sudo" from the front of the command, as it may not be needed by your Linux distribution.
  • If assigning an IP address to a computer that has more than one network adaptor, use "eth1" for the second network adaptor, "eth2" for the third network adaptor and so forth.
