360 Systems DigiCart/E - Manual (Page 26)

• Administration
DigiCart can assume (192.168.1.16 to 192.168.1.32) to ensure that they are available for use if necessary. An
exclusion of 192.168.2.16 to 192.168.2.32 can be programmed in the subnet 2 scope if present.
All fixed IP Addresses in the system must either fall outside the range of all Scopes, or have exclusions
programmed for them.
See Windows 2000 Server Help for further information on programming DHCP service.
File Sharing
Before any DigiCart/E recorders on the network can utilize the NFS file server, you must configure the server
to share (or export) any directories you want them to see. Initially at least, you must set these shared
directories to allow both reading and writing for all users. When using Windows Services for UNIX, there is a
separate mechanism for NFS sharing apart from the normal Windows file sharing scheme.
Create several folders in which the DigiCart audio is to be held. You might have one dedicated to sound
effects and others for files related to various projects you may be working on. It doesn’t matter where in the
server’s directory hierarchy the new folders exist. The names you give to these folders will become drive
names from the DigiCart perspective, so it is good to be concise. If you right-click on one of these folders, a
pop-up window appears that lets you enable NFS sharing. The share name defaults to the name of the folder,
and all share names must be unique. If you try to share duplicate folder names you will be prompted to select
a different share name.
The NFS Share names should be the same as their folder (Windows directory) names, and should be no more
than 14 characters. The DigiCart user sees the NFS Share name, not the folder name, when mounting a
network drive or selecting drives. An administrator working at the server or other attached computer sees the
folder name. NFS Share names cannot contain spaces, the underscore character ( _ ) is used instead.
When an available drive number on a DigiCart/E is assigned to one of these shared folders, the DigiCart will
create within this folder 11 new directories, 10 for holding audio files, and one dedicated to playlists. Hence,
the standard DigiCart directory structure will automatically be established.
Do not add additional folders to a network drive folder. It is best to avoid adding non-DigiCart files to a
DigiCart network drive; however, a limited number of small data files can be placed in the folder. For
example, a text file describing the contents of the drive.
Make sure the permissions are set to allow both reading and writing for everyone, unless you need to restrict
access. (This is the default in Windows Services for UNIX 2.0. Version 3.0 defaults to read only, and also
requires you to check “Allow Anonymous Access”. See the section Setting Up Ethernet Audio Directories.)
File Security
Individual net drives can be protected from editing or deletion of any contained file, or addition of files by
copying or recording. On the server, right click the net drive folder and select Properties. Click the NFS
Share tab, and select Read Only. Click Accept and OK. It is also possible to protect individual files,
directories or net drives by selecting the Read Only attribute in properties.
Permissions can be set up to allow some DigiCarts to have full access to a net drive and others Read Only or
no access. This is accomplished by setting up User Groups that contain one or more DigiCarts and then
specifying those groups as having write permission in the NFS Share properties of the net drive.
1. Determine the IP addresses of the DigiCarts that are to have full access to the net drive. The current
IP address of the DigiCart is displayed by pressing the Enter key while in Stop mode. Each press of
Enter alternates between displaying the IP address and the machine ID number.
2. On the server, run Services for Unix Administration (Start>Programs>Services for Unix>Services for
Unix Administration)
