Creating_a_File

   Use the XAUTH -f ADD command to manually create an X authority
   file. You must manually create an X authority file for the
   server when enabling authentication outside of a DECwindows
   Motif session. You can also choose to create additional user X
   authority files to store alternate authentication settings, such
   as for authorizing untrusted network connections.

   An X authority file name can consist of any characters currently
   supported by OpenVMS; however, the file extension is restricted
   to a maximum of 37 characters and version numbers are not
   allowed.

   The -f option specifies the name of the X authority file, and
   the ADD command creates the file by adding an entry. If you do
   not enter a fully-qualified filename, the new X authority file is
   written to the current directory by default.

   For example, the following command creates a new X authority file
   UNTRUSTED.DECW$XAUTH to be used to authorize untrusted network
   connections:

   $ XAUTH -f UNTRUSTED.DECW$XAUTH ADD :0 .
