Verifying the TCP/IP configuration

 

After configuring TCP/IP, you should verify that the configuration is correct.

You can verify that TCP/IP is set up correctly on your PC by issuing a PING command to the System i™ platform:

  1. Open a command prompt.

  2. Type PING system where system is the name of the System i platform that you want to connect to.

  3. If your TCP/IP configuration is correct, you should see reply messages from the System i platform. If you do not see these reply messages, here are some possible reasons why the PING command failed:

    • You might be trying to PING the wrong address. Check the address of the System i platform.

    • You might have an incorrect IP address listed for the System i platform in your HOSTS file or DNS entry. This occurs only when you try to PING a System i platform by name (as opposed to the IP address). If so, try PING nnn.nnn.nnn.nnn where nnn.nnn.nnn.nnn is the IP address of the System i platform that you want to connect to. You can obtain the IP address of the System i platform from your system administrator. If that works, update your HOSTS file or DNS entry with the correct address.

    • Incorrect LAN adapter address is set in the adapter properties on the PC.

    • There is no physical connection to the System i platform.

    • The System i platform or network name is not correct.

    • TCP/IP is not configured correctly on the PC.

    • TCP/IP is not installed or configured correctly, or is not started, on the System i platform. These problems need to be addressed by the system administrator.

    • The System i platform is down.

    • The System i platform is located behind a firewall that will not allow you to PING. Try telnet systemname.

    • If none of the above explain your problem, restart and go through the configuration process again.
