Communications Problems

Problem:

ZY is up and running, but connection is refused.

Possible Cause:

Some other program may already be connected to the ZY.

Remedial Action:

Wait for ZY to become free or disconnect the other program.

Problem:

ZY is up and running, but host cannot be found.

Possible Cause:

The network software on the ZY may not be properly configured.

Remedial Action:

Check the connection with the `ping' command from another host. If this fails, verify the configuration of the network software on the ZY[21].
