Answer / Solution

No such host is known. The name you used is not an official host name or alias. This is not a software error, another type of name server request may be successful.
Check that you have a name server(s) and/or host table configured. If you are using a name server(s), check whether the server host(s) are up (e.g. try to ping the server(s)). You could also try to resolve another host name you know should work, to check if the name resolution server application is running.
