NAME

       asecure - control access to Audio on a workstation (OBSOLETED)

SYNOPSIS

       [] [] [] [] []
	      [] [] [] []

DESCRIPTION

       On  Series 700 workstations, audio is secured so that only the user on the local workstation can access audio.  You use the command to mod-
       ify audio security. This command does not apply to X stations; on an X station, access to audio is unrestricted.

       To modify audio security, become root on the local workstation where you want make a change.  Then, use as follows:

       When prompted, enter any meaningful password.  Issuing creates the Audio Security File (ASF).  The ASF contains information that determines
       which hosts and users can access the Aserver, and which users (other than the superuser) can modify the ASF.

       If needed, you can allow unrestricted access to audio on this workstation.  To remove audio security, issue this command:

       If  instead,  you wish to modify security, you use to make changes to the information in the ASF.  (Because the ASF is a binary file, we do
       not recommend using an editor on this file.)  You can use to make these types of changes:

	      o  Allow all clients from a remote host to access the server.

	      o  Allow specific users from all other hosts to access the server.

	      o  Allow a specific user from a specific host to access the server.

	      o  Disable access control, allowing complete unrestricted access to the server, but leaving the ASF intact.

       Every operation that creates, reinitializes, or changes the contents of the ASF is logged in the file, so that you can track any changes to
       the ASF.

   Options
       supports the following options:

	      Add/delete     hostname,username	pair. You must be either superuser or a to do this. You can supply more than one hostname,username
			     pair separated by blanks.

			     To use either the or options, you MUST supply at least one hostname,username pair. This option will not work  without
			     a pair.

	      Create a new ASF file, called the
			     file. Access control default is enabled with no entries in the access list. Aserver can now be accessed only by local
			     users on the host machine. If an file already exists, it is re-initialized.

			     You must be superuser to execute this option. This option is mutually-exclusive of all other options.

			     This option requires a password. This is an extra layer of protection for the contents of the ASF. It is designed	to
			     prevent  surreptitious manipulation of the ASF. If you are creating a new ASF, you are prompted for a password and an
			     encrypted copy of that password is stored in the new ASF.

			     If the ASF already exists, you are prompted for the password. If your password matches the  password  stored  in  the
			     ASF, the ASF is then re-initialized.

	      Disable access control to the Aserver. This allows unrestricted access by
			     all clients.

	      Enable access control to the Aserver. This restricts access to clients listed
			     in the ASF. Enabled is the default state.

	      Add/delete     hostnames	for  ALL  users. You must be either superuser or a to do this. You can supply more than one hostname sepa-
			     rated by blanks.

	      List the contents of the ASF. This option shows a list of the hostnames
			     and/or usernames that have access to the Aserver.

	      Change password for
			     file. You must be superuser to do this. You are prompted once for the old password, then prompted twice for  the  new
			     password.

	      Add/delete     You  must	be  superuser to do this and must enter the password given when the ASF was created (see option). To see a
			     list of privileged users, you must be superuser and use the option.

	      Add/delete     usernames for ALL hosts. You must be either superuser or a to do this. You can supply more than  one  username  sepa-
			     rated by blanks.

EXAMPLES

       List entries in access list.

       Disable access control. This means anyone can connect to Aserver without restriction.

       Add host for all users to access list. Remove host for all users from access list.

       Add user for hosts and to access list.

       Add user to access list for all hosts. Remove users and from access list for all hosts.

       Create new access list.
