HELIOS EtherShare UB User manual

3 HELIOS Admin

This cross-platform based administration service is comprised of two components, the HELIOS Admin server and the HELIOS Admin client.

The HELIOS Admin client is a convenient tool that allows configuring users, groups, volumes, printer queues, etc., and which is supported for various client platforms due to its Java heritage. For details see the chapter "HELIOS Admin" in the Base manual.

In this manual we focus on the EtherShare related usage of HELIOS Admin, such as configuring AFP volume settings, PAP printer settings, etc.

Note: EtherShare Administration server and EtherShare Admin are still supported by HELIOS, but it is recommended to use the cross-platform HELIOS Admin instead. For details on EtherShare Admin, refer to the EtherShare 2.6 manual on the HELIOS product CD-ROM, or in the "HELIOS Applications" volume.

3.1 General remarks

This chapter describes the use of the application HELIOS Admin to perform EtherShare related configuration from any workstation in a convenient and secure way.

In order to use HELIOS Admin, the HELIOS Admin server must already be running on the host you want to configure. The HELIOS Service Controller is configured to start this server automatically when the system is booted.

Other chapters in this manual describe how administrative work, which is required to configure and maintain the EtherShare system, can be carried out directly on the host, e.g. by using "prefvalue" (see "HELIOS utility programs" in the Base manual). Most of these tasks can be carried out much easier using HELIOS Admin from one of the workstations.

HELIOS Admin offers a high degree of convenience to the system administrator. The application allows the host configuration to be represented graphically with lists and windows. Using HELIOS Admin from any workstation, server users, groups, volumes, and printers can be installed, configured and deleted. You can also interrogate each PostScript printer for available resident fonts and install downloadable fonts to the print server.

HELIOS Admin accesses and modifies the "Preferences" configuration file just as if the changes had been made manually. However, HELIOS Admin and the HELIOS Admin server have built-in safety checks to avoid conflicting or invalid configuration settings.

HELIOS Admin has the additional advantage that almost all changes are immediately effective, without having to restart the affected service.

Benefits:

• Any new suffix mappings or changes to existing ones will be available immediately.
• Any new HELIOS volume or printer will be available immediately.
• Any changes to HELIOS volumes, e.g. setting groups membership, will be available immediately.

Potential drawbacks:

• Any changes to HELIOS volumes, e.g. removing or changing mount points, switching characteristics to read-only, or changes in groups membership may result in side effects for EtherShare clients. This may range from write errors to volumes getting dismounted(!).
• Especially important - Removing access rights to volumes for clients that still have documents open on that volume might cause damaged or only partially saved documents.

Make it a habit to check the Active Users list prior to making any changes that might affect connected users. Use the HELIOS Admin feature to send messages to connected clients to notify them in advance of potentially damaging changes. In the Active Users list you can verify which users have certain volumes in access.

3.2 Macintosh server settings

In the Settings > Server Settings window (Fig. 1), in the Macintosh tab, you can specify the Server Name (if no server name is specified here, the system uses the host name) and select the AppleTalk Zone and the Default Client Charset. From the IP Access pop-up menu choose the desired IP access list for the server. The chapter "HELIOS Admin" in the Base manual describes in detail how to edit the default IP access list according your needs.

Note: If you wish to share both HELIOS server volumes and other Mac OS X server volumes via the native AFP file sharing, then the HELIOS server must be assigned a Macintosh server name that is different from the OS X server name.

3.3 Volume AFP settings

This chapter refers to AFP related volume settings only. For general information on volume settings and instructions on how to change them see "Volume settings" in the HELIOS Admin chapter of the Base manual.

The Volumes list shows all HELIOS volumes on the host (Fig. 2). The HELIOS Admin server automatically creates this list by inspecting volume-related entries in the "Preferences" file (see "Volume preference keys" in the Base manual).

Choose the Volumes tab. If it is not available, activate it in the Lists menu.

Changing AFP volume data

Before changing AFP volume data, make sure that the volume is not in use. All users should unmount the volume, because changes take effect immediately and this could lead to strange effects.

Select the volume name, and choose Open from the File menu (or double-click the volume name).

The Macintosh tab displays the AFP information about the selected volume (Fig. 3).

Fig. 3: Macintosh tab on host "ankh"

The Macintosh visible checkbox determines whether the volume is visible at all in the Macintosh Connect To Server- dialog (Mac OS X) or in the Chooser (Mac OS 8/9).

The AFP Name field allows specifying the name by which the volume is published in an AFP environment, and which is visible in the "AFP Name" column (Fig. 2).

The Password field allows specifying a volume specific password, which Macintosh clients must enter prior to mounting the volume.

Important: The Password option remains without effect on Windows users in case the volume is also published in the Windows environment!

From the AFP Charset pop-up menu you can choose the AFP character set which is used by the volume: MacRoman, MacIcelandic, EUC-KR, or SJIS.

If AFP UNIX Permissions is NOT active, a folder inherits the permissions of the parent folder when used with Mac OS X clients.

3.4 Printer spooler settings

This chapter refers to AppleTalk "papsrv" settings only (see papsrv in 7.2 "The print server programs"). For general information on printer settings, e.g. how to create and delete printers see "HELIOS Admin" in the Base manual.

The Printers list shows all HELIOS printer queues on the host (Fig. 4). The HELIOS Admin server automatically creates this list by inspecting printer-related entries in the "Preferences" file (see "Printer preference keys" in the Base manual).

Choose the Printers tab. If it is not available, activate it in the Lists menu.

Before changing printer data, make sure that the printer is currently not in use.

Select the printer, and choose Settings from the Printer menu (or double-click the printer name while holding down the Option key).

The Macintosh tab displays information about the selected printer (Fig. 5).

Macintosh PAP

The name of the AppleTalk PAP printer (PAP Name) is specified in the Macintosh - PAP section. This is the name by which it is known to the network. In addition, an AppleTalk Zone - if available - can be chosen from the pop-up menu. The AppleTalk name of the printer only becomes visible in the network if the Macintosh - PAP checkbox is active.

Mac OS 8/9 clients only: The Require Authentication checkbox determines whether printing to a LaserWriter queue is password-protected or not. If active, user name and password have to be entered before printing.

HELIOS TCP

The TCP Name field in the TCP Printer section specifies the name under which the TCP printer is registered by SLP, and under which this printer can be reached via the master TCP port. The TCP name of the printer only becomes visible in the network if the TCP Printer checkbox is active.

For instructions on how to create and configure a HELIOS TCP Printer see 7.4.1 "Mac OS 8/9 client configuration" and 7.4.2 "Mac OS X client configuration".

Optionally, a dedicated TCP/IP port can be set:

Specify a port number for the TCP printer in the Port field.

Defining a port may be helpful to share a TCP/IP queue over the internet. By default all EtherShare printer queues are handled on port 2007.

3.5 PAP printer output settings

AppleTalk (Fig. 6) connects a printer to the server via AppleTalk.

To set the printer type to AppleTalk PAP (see papif in 7.2 "The print server programs"), choose AppleTalk from the pop-up menu of the Interface tab (Fig. 6).

Then the AppleTalk type, zone and name of the printer must be specified. You only need to change the default Type (LaserWriter) if printers of other types, such as AppleTalk ImageWriter printers, are available.

Now choose the Zone in the pop-up menu and then click on the Name menu to pop up a list of all devices of the specified type that are available in the selected zone.

The list is determined by interrogating the network for all printers. Accordingly, the printer you wish to configure must be connected and online.

Choose a printer and click Save.

Important: Make sure that you choose a physical printer from the list, and not another printer queue!

The Hide Printer option - which is only available with the printer type "LaserWriter" selected in the Type pop-up menu - may be checked if you want to prevent the printer from being displayed in Apple's Printer Setup Utility. Thus, users cannot choose this printer and thus cannot print directly to the output device. This is reasonable because printing to an output device both directly and through a spool queue may lead to long waiting periods on the Macintosh, e.g. if the printer is executing a large job from a queue and the job that has been sent directly is not accepted instantly.

If any of the entries in Zone/Name is displayed in italics, this indicates that this zone or device is currently not available. You should make sure that the desired printer is connected and online.
