Changing Network Parameters of the Operating System

Changing Network Parameters of the Operating System

This section describes how to change the hostname/DNS and IP address of the operating system.


The tool of the eLog will be used to change the host name. The tool is in the eLog software installation package. In addition, the tool of the eLog will be used if one IP address is configured for bound NICs. This tool is also in the eLog software installation package.

Therefore, ensure that the eLog installation software is available. That is, the CD-ROM is available, or the software package has been downloaded. If the installation package is used, the integrity check is required. For details, see section Checking the Integrity of the Software Package. For how to send the software package to the server, see Using the WinSCP Tool to Send the Software Package to the Server.


  1. Log in to the Linux operating system as user root.
  2. Right-click the desktop and choose Open in Terminal from the shortcut menu to access the CLI.
  3. (Optional) Change the IP address and configure DNS.


    This step is used to configure an IP address for each NIC. To configure an IP address for bound NICs, see Configuring a Backup Port for the Web Access Port Using the Dual-NIC Binding Tool.

    1. On the CLI, run the following command. The Administrator Settings window is displayed.
      # yast2
    2. Select System > Network Settings.

    3. (Option) Click the Hostname/DNS tab, change the DNS server, and click OK.
    4. On the Overview tab, select the IP address to be changed and click Edit. The Network Card Setup dialog box is displayed.

    5. Click the Address tab, change the IP address, and click Next.

    6. Click Yes.
    7. Click the Routing tab, change the default gateway, and click OK.


      After configuring the default gateway on the Routing tab, run the ping command on the server to ping the default gateway. Ensure that the server and default gateway are reachable, so that the server can communicate with other devices.

  4. Use the tool provided by the eLog to change the host name of the operating system.

    1. Run the cd installation-file-path/tools command to access the directory of the tool.

      If the CD-ROM is used, the directory where the installation file resides is displayed after the CD-ROM is inserted. Access the tools directory, right-click and choose Open in Terminal from the shortcut menu to access the CLI, and run the subsequent commands.

      If the software package is used, the directory of the installation file is the decompressed directory of the installation package, for example, /opt/LogCenter_Install.

    2. Run the chmod +x command to empower the tool.
    3. Run the ./ command command to change the host name of the operating system and enter the new name.

  5. Restart the operating system to make the settings to take effect.
