You can test whether your connection method to iSeries™ NetServer™ (for example, Domain Name System) is running if you experience connection problems.
To test your connection, follow these steps:
ping QSYSTEM1
QSYSTEM1 is the server name of iSeries NetServer on the i5/OS operating system.
If you get a positive return value, then the client connection to iSeries NetServer is operating normally. This means that the method the client uses to connect to iSeries NetServer and to the system is working.
