Method Detail

getHostName

public static java.lang.String getHostName()

Returns the host name of the local machine. This method first tries to determine the host name by running the "hostname" command. If this is not successful, the "HOSTNAME" (for UNIX-like systems) and "COMPUTERNAME" (for Windows) environment variables are tried. If the respective environment variable is not defined either, InetAddress.getLocalHost() is tried. If that method does not return an address with a valid host name or throws an exception, null is returned.

Returns:

host name of the local machine or null if the host name cannot be determined.
