for Linux
The Novell® ClientTM for Linux* software allows users of Linux workstations to access and use all of the services available on servers running Novell eDirectory power, ease of use, manageability, and security of eDirectory to Linux workstations. The Novell Client for Linux fully supports NetWare workstation, including security, file, and print services through Novell iPrint.
This section contains the following information:

1.1 Understanding How the Novell Client for Linux Differs from the Novell Client for Windows 2000/XP
Using the Novell Client for Linux differs in a few ways from using the Novell Client for Windows*. For users and network administrators who are familiar with the Novell Client for Windows, knowing these differences can help the transition to Linux run more smoothly.

Installation and Upgrades
The Novell Client for Linux can be installed and upgraded using either YaST or an installation
script. For more information, see the “Novell Client 2.0 for Linux Installation Quick Start.”
There is no Automatic Client Upgrade available on Linux.
The Client Configuration Wizard lets you set up a configuration file that can be used to
preconfigure workstations during installation. For more information, see Section 2.2, “Using
Configuration Files to Preconfigure the Novell Client,” on page 20.
Logging In
When a user logs in to a local workstation and then opens a remote SSH session and logs in as
the same user, the network resources that user has rights to are available to the user.
The Novell Client for Linux can use the NMAS
NMAS login is not integrated in to the Novell Client for Linux login screen, so the default login sequence cannot be set in the Novell Client Login screen.
The Novell Client for Linux uses OpenSLP, whereas the Novell Client for Windows uses
Novell’s implementation of SLP. The network administrator must set up OpenSLP before users can look up trees, contexts, and servers using the Browse buttons in the Novell Client Login window. If OpenSLP is not set up, the user must enter a username, tree, and context to connect to the network. See Chapter 3, “Managing Login,” on page 23 for more information.

login method to authenticate. However, the
Understanding the Novell Client for Linux

Because Linux uses OpenSLP, the implementation is different and the user’s experience is different. For more information, see Section 3.4, “Using OpenSLP to Simplify Login,” on
page 27.
The Novell Client for Linux does not use the Dynamic Local User or Location Profiles that are
available in Windows.
User Interface
Both a graphical user interface and command line utilities are available to complete client actions such as mapping drives, setting trustee rights, and copying files.
Login Scripts
Novell has ported the vast majority of login script functionality to the Linux platform. This means that the login scripts you create in your network can be used for both Windows users and Linux users with very little difference in functionality.
Some differences do exist, however. For example, mapped drives are implemented by creating symbolic links and search drives are not available on Linux. Other small differences are created by the inherent difference between Windows and Linux. All the differences and issues are listed in the
Novell Login Scripts Guide.
novdocx (en) 26 August 2007
1.2 Understanding the Novell Client for Linux Virtual File System
The Novell Client for Linux differs from previous Novell Clients to enable it to work on the Linux platform. In Windows, the Novell Client loads a single binary that works on multiple operating system platforms without modifications. The Novell Client for Linux has a Virtual File System that consists of a kernel module (novfs.ko) that runs as part of the Linux kernel and a daemon (novfsd) that runs in the user space. Both components must be running on the workstation for the client to connect to the network.
The daemon can run on any of the supported Linux platforms without modification. The kernel module, however, is dependent on the kernel version and must be compiled to match the kernel on the workstation. When the Novell Client is installed, it compiles the kernel module during the installation process. If this process fails, the kernel module cannot load. It attempts to recompile when the workstation is restarted.
1.2.1 Understanding When the Virtual File System Kernel Module Needs to Be Compiled
The following is a list of the instances when you must compile the Novell Client Virtual File System Kernel Module (novfs.ko):
You installed the Novell Client and received an error message. This generally occurs because
all the required packages are not installed on a workstation. You must install these packages, compile the Novell Client Virtual File System Kernel Module (novfs.ko), and restart the workstation. See “System Requirements” in the Novell Client for Linux Installation Quick Start for more information.
You have previously compiled the Novell Client Virtual File System Kernel Module
(novfs.ko) and then made changes to the kernel.
10 Novell Client 2.0 for Linux Administration Guide
You have a custom kernel of any of the supported versions.
Kernel updates are automatically pushed to the workstation via Red Carpet
®
.
In all of these instances, you must recompile the Novell Client Virtual File System Kernel Module (novfs.ko) to ensure that it is compatible with the Linux kernel version on your workstation. However, when later shipping versions of SLED are provided by Novell, the Novell Client Virtual File System Kernel Module (novfs.ko) is installed and you do not need to recompile it because the module is included in the kernel.
For more information, see Appendix A, “Compiling the Novell Client Virtual File System Kernel
Module,” on page 45.
NOTE: If you patch the kernel for any reason, you must make sure that you have the required packages that correspond to the kernel patch. For a list of the required packages, see “System
Requirements” in the Novell Client for Linux Installation Quick Start. The Novell Client for Linux
then recompiles when the workstation is restarted. Without the corresponding packages, the recompile fails.
Under certain conditions, your version of novfs.ko could be rolled back when you install a new kernel module. For example, if you download and install a patched version of novfs.ko, and then later install an SLED 10 update to your kernel, the Novell Client Virtual File System Kernel Module patch might be overwritten. You should then reinstall the novfs.ko patch and recompile the kernel in order to ensure that the kernel module and the kernel are compiled.

) during login. NMAS authentication can add additional security to the network, but
if the network does not use NMAS, login might take additional time, so you can disable NMAS authentication by disabling this setting. This option is selected by default.
Clear Previous User Name: Clears the previous username from the User Name field on the
Novell Login dialog box every time you open the dialog box.
Advanced Button: Enables or disables the Advanced button in the Login dialog box. This
option is selected by default.
Integrated Login: Enables the integrated login feature for the entire system. This is set by the
administrator and cannot be overridden by the user.
Display Integrated Login Results: When this option is disabled, all login scripts are run
silently and the script results window is not displayed, but login scripts are still processed.
Delete Integrated Login Profiles: Removes the existing login profiles for all users on this
workstation.
Default Tree: Specify the default tree that Login attempts to log in to. This setting is
overridden by the Login Dialog Tree history.

For more information on using the Novell Login dialog box, see “Logging In to the Network” in the Novell Client for Linux User Guide.
2.1.2 Configuring Map Settings
Use the Map Settings page in the Novell Client Configuration Wizard to specify the directory on the local workstation where symbolic links to network resources are created and to select the first letter to use when creating these links.
Figure 2-2 Map Settings Page
Configuring the Novell Client for Linux 15
This page contains the following options:
Map Link Default Location: Specify the path to the directory where Map creates symbolic
links to network resources. A value of %HOME (the default) causes Map to create symbolic links in the user’s home directory.
First Network Drive: Select the first letter for Map to use when creating symbolic links to
network resources. This setting is used in commands such a Map *1 or Map next.
2.1.3 Configuring Protocol Settings
Use the Protocol Settings page in the Novell Client Configuration Wizard to determine the level of enhanced security support, select the providers to perform name resolution, and enable the Client to obtain configuration information from your DHCP server.

Changing the value of this setting to 2 or 3 increases security but decreases performance.
Dynamic Host Configuration Protocol (DHCP): If a DHCP server is set up on your network,
the DHCP server can inform the Novell Client of network-specific configuration information. This information is made available when a user click the Tree, Context, or Server buttons on the eDirectory tab of the Novell Login dialog box.
If you make changes to the Protocol Settings page, you must reboot the workstation for those changes to take effect.
2.1.4 Configuring Tray Application Settings
Use the Tray Application Settings page in the Novell Client Configuration Wizard to automatically launch the Novell Client Tray Application when the desktop starts and to determine which options are available to users on the Tray Application menu.

18 Novell Client 2.0 for Linux Administration Guide
Volume Statistics: Enables or disables the Volume Statistics tab on the Volume Properties page
(available when users right-click a Novell file system volume in a file manager and then click Novell Properties).
2.1.6 Configuring OpenSLP Settings
Use the Service Location Protocol (OpenSLP) Settings page in the Novell Client Configuration Wizard to specify where and how the Client requests network services.
In an IP-only network, the Novell Client needs a way to resolve the eDirectory tree, context and server names to an actual IP address of an eDirectory server that can provide authentication. On a simple LAN, the client can send an IP broadcast to discover this information, but on a multisite WAN, the SLP scope and Directory Agents must be listed.
Figure 2-6 Service Location Protocol (OpenSLP) Settings Page
novdocx (en) 26 August 2007
This page contains the following options:
Scope List: Specify the scopes that a user agent (UA) or service agent (SA) is allowed when
making requests or registering, or the scopes that a directory agent (DA) must support.
Directory Agent List: Specify the specific DAs that UA and SA agents must use. If this
setting is not used, dynamic DA discovery is used to determine which DAs to use.
Broadcast Only: Select this option to use broadcasting instead of multicasting. This setting is
not usually necessary because OpenSLP automatically uses broadcasting if multicasting is unavailable.
SLP is designed to use IP multicasting; however, if any SLP Agent does not implement IP multicasting, then all Agents must use broadcasting to reach that Agent. If a DA does not support multicasting, we recommend using the Directory Agent List to configure that Directory Agent rather than using this option.
Configuring the Novell Client for Linux 19
If the network does not contain a DA, IP servers must use their own SAs to specify the services that are available. If the SA does not support multicasting and if there are any services advertised by that SA that are needed by the UA on this machine, then use the Broadcast Only option.
Broadcasting has the disadvantage of being limited to the local LAN segment.
Maximum Results: Specify a 32-bit integer giving the maximum number of results to
accumulate and return for a synchronous request before the time-out, or the maximum number of results to return through a callback if the request results are reported asynchronously.
If you make changes to the Service Location Protocol (OpenSLP) Settings page, you must reboot the workstation for those changes to take effect.

2.2 Using Configuration Files to Preconfigure the Novell Client
novdocx (en) 26 August 2007
The Novell Client for Linux allows you to apply preconfigured client settings contained in one or more configuration (.conf) files. This option works similar to the unattend file that can be used to configure the Novell Client for Windows (see Creating the Configuring File (http://
www.novell.com/documentation/noclienu/noclienu/data/bu01sei.html#hn62kppa) in the Novell
Client for Windows Installation and Administration Guide for more information).
Preconfiguring the Novell Client for Linux requires the novell-client-conf.spec file and the make_novell-client-conf_rpm Bash script located in the /add-on/novell- client-conf subdirectory in the directory where you unarchived the Client download file.
1 Create the preconfigured settings using the Novell Client Configuration Wizard.
See Section 2.1, “Using the Novell Client Configuration Wizard,” on page 13.
2 Copy the appropriate .conf files to the /add-on/novell-client-conf directory.
Depending on the settings you preconfigured, copy one or more of the following files:
Conf File Path and Name Configuration Settings
/etc/opt/novell/ncl/file_browser.conf File browser settings
/etc/opt/novell/ncl/login.conf Login settings
/etc/novell/ncl/map.conf Map settings
/etc/opt/novell/ncl/protocol.conf Protocol settings
/etc/opt/novell/ncl/tray_app.conf Novell Client Tray Application settings
/etc/slp.conf SLP configuration settings
3 Run the make_novell-client-conf_rpm script to create a novell-client-conf-
version_number.platform.rpm file (for example, novell-client-conf-
1.0.0-0.i586.rpm) using all of the .conf files contained in the /add-on/novell­client-conf directory.
20 Novell Client 2.0 for Linux Administration Guide
3a Make sure you are the root user.
3b Enter the following in a terminal:
bash make_novell-client-conf_rpm
4 Install the preconfigured settings contained in novell-client-conf-
version_number.platform.rpm using one of the following methods:
Install manually in a terminal: Enter rpm -i novell-client-conf-
version_number.platform.rpm in a terminal.
Install using the ncl_install script: When you launch the ncl_install script (located
in /opt/novell/ncl/bin or in the directory where you unarchived the Client download file), it looks for novell-client-conf- version_number.platform.rpm in the /add-on/novell-client-conf directory and adds it to the list of RPMs it installs as part of the Client.
Install with the Novell Client using YaST: Add the location of the newly created
novell-client-conf-version_number.platform.rpm to the list of installation sources in YaST (add a local directory in the Installation Source option and point it to the directory containing novell-client-conf-
version_number.platform.rpm). When the YaST install runs, novell- client-conf-version_number.platform.rpm is added as one of the RPMs in
the Novell Client selection.
The Novell Client configuration settings on a workstation can be updated at any time using the YaST method.
novdocx (en) 26 August 2007
The .conf files contained in the RPM are copied to the /etc/opt/novell/ncl directory, overwriting the files of the same name that already exist there. The installation then copies the slp.conf file to the /etc directory, overwriting that file as well.
TIP: Backup copies of the existing files are made in the same directory so that you can revert to the old files if you need to.

IMPORTANT: The integrated login feature is not available if you log in as the root user, and the integrated login feature does not work if a workstation is set up to not ask for a password in the display manager greeter.
For integrated login to work, the Novell Common Authentication Services Adapter (CASA) must be installed and enabled. CASA is a common authentication and security package that provides a set of libraries for application and service developers to enable single sign-on to an enterprise network.
3.1.1 Installing and Enabling CASA
CASA is installed by default with SLED 10 SP1, but it is not enabled. CASA is not installed or enabled by default with openSUSE 10.2.
Installing CASA
1 Launch the YaST Control Center.
GNOME: Click Computer > More Applications > System > YaST.
KDE: Click the menu button > System > YaST.
2 If you are not logged in as root, type the root password, then click Continue.

3.1.3 Managing System Wide Integrated Login Settings
1 Launch the Novell Client Configuration Wizard using either of the following methods:
Click > System Settings.
In YaST, click Network Services > Novell Client.
2 Select Login, then click Start Wizard.
novdocx (en) 26 August 2007
3 On the Login Settings page, select or deselect Integrated Login.
This enables or disables the integrated login feature for the entire system. This is set by the administrator and cannot be overridden by the user.
4 Select Display Integrated Login Results to display the Integrated Login Script Results window
when the user desktop is launched.
If this option is disabled, all login scripts are run silently and the Integrated Login Script Results window is not displayed, but login scripts are still processed.
5 Select Delete Integrated Login Profiles if you want remove the existing login profiles for all
users on this workstation.
6 Click Finish.
3.2 Setting Up Login Scripts
When a user successfully logs in to the network, one or more login scripts are executed that automatically set up the workstation environment. Login scripts are similar to batch files and are executed by Novell Login. You can use login scripts to map drives to Novell file system volumes and directories, display messages, set environment variables, and execute programs or menus.
Login scripts were originally created for use with the Novell Client for Windows. However, the Novell Client for Linux can take advantage of the majority of the functionality available in Windows. This means that the login scripts you created for Windows workstations can also be used with Linux workstations without modification, so you need to administer only one set of login scripts.
Because login scripts are very flexible and dynamic, offer a high degree of customization, and are cross-platform, you should customize the scripts to optimize workstation login to your network. For more information on setting up login scripts, see the Novell Login Scripts Guide.

3.3 Setting Up Login Restrictions
novdocx (en) 26 August 2007
Login restrictions are limitations on user accounts that control access to the network. These
TM
restrictions can be set by an administrator in Novell iManager for each user’s eDirectory
User
object and include the following:
Requiring a password
You can specify its minimum length, whether it must be changed and how often, whether it must be unique, and whether the user can change it.
Setting the number of logins with an expired password and the number of incorrect login
attempts allowed
When a user violates login restrictions by entering an incorrect password or exceeding the number of logins with an expired password, the account is disabled and no one can log in using that username. This prevents unauthorized users from logging in.
Setting account limits such as an account balance or expiration date
Limiting disk space for each user by specifying the maximum blocks available for each user on
a volume
Specifying the number of simultaneous connections a user can have
Specifying (by node address) which workstations users can log in on
Restricting the times when users can log in (you can assign all users the same hours or you can
restrict users individually)
To manage user login restrictions:
1 Launch iManager by entering the following in the Address field of a network browser:
http://server_IP_address/iManager.html
2 Log in using your username and password.
You will have access only to those features you have rights to. To have full access to all Novell iManager features, you must log in as Supervisor/Administrator of the tree.
3 Make sure you are in the Roles and Tasks view by clicking on the top button bar, then select
Users > Modify User in the navigation panel on the left.
4 Type the name and context of the User object you want to modify, or use the search feature to
find it, then click OK.
5 Click the Restrictions tab (or drop-down list, depending on the browser you are using).

3.4 Using OpenSLP to Simplify Login
The service location protocol (SLP) was developed so that networking applications such as the Novell Client for Linux could discover the existence, location, and configuration of networked services in enterprise networks. Without SLP, users must supply the hostname or network address of the service that they want to access.
Because SLP makes the existence, location, and configuration of certain services known to all clients in the local network, the Novell Client for Linux can use the information distributed to simplify login. For the Novell Client, having SLP set up allows users to see the trees, contexts, and servers available to them when they use the Novell Client for Linux Login screen. When they click the Browse button, a list of available trees, contexts, or servers appears and they can select the appropriate ones. For example, instead of remembering an IP address or DNS name for a server, users can select the server’s name from a list of available servers.
SLP must be activated and set up on your Novell servers in order for the Novell Client to take advantage of it. For more information, see “SLP Services in the Network” in the SUSE LINUX
