Environment

Novell ZENworks 10 Configuration Management

Situation

ERROR (from Discovery task error on ZCC):
 
"Unable to ping the device <ip address> by using the ping command.  Probable cause: The device may be unreachable

Resolution

The ping request to the discovered device is initiated by the linux server, not the discovery winproxy device.  If the discovered device is running, check that it can be pinged from the linux ZCM server.  If the ZCM server has problems pinging the device enable both ping request and ping response services in the server's firewall.
