Linux-based HP Compaq t5125, t5515, t5525 Thin Clients
This guide provides the network administrator with instructions for
local and remote configuration of the Linux-based thin client and
explains the various configuration utilities. This guide provides
instructions for both the HP Compaq t5125, t5515, and t5525 thin
client.
Not all features described in this guide are available in all
✎
Linux-based terminal models.
Typically, you configure a terminal locally and then use it as a
template for other terminals, which you can then configure using
remote administration tools. You can create server and application
connections through the XFce Settings Manager Network
management interface.
Chapters in this guide are specific to the desktop interface and
programs in the XFce Settings Manager, which is the control panel
for the Linux-based image.

A default user account is pre-installed with the following settings:
✎
User name: root
Password: root
This default account is also the Administrator “rights” account for
Linux. Therefore, HP recommends that you change the password and
create a new separate user account for non-administrator users.

Introduction
Thin client image
HP developed this Linux image especially for thin client use by
integrating a comprehensive set of open source, commercial, and
custom-developed components. You can use the Altiris client to
provide remote management of the thin client and to upgrade the
Linux image with feature enhancements, device drivers, and
maintenance updates.

Introduction
Programs
Console
The following sections describe the programs available on the
desktop. Program access depends on your thin client. You can
configure the thin client so that the user will have access to these
programs through HP Connection Administrator or Citrix.
The Console provides a dialog box with a prompt # for entry of
various shell commands. To start the Console, right-click anywhere
on the desktop and select Console.
The suite of commands provided come from the BusyBox suite. You
can determine the specific commands currently supported once you
invoke the Console dialog box. For a list of supported commands,
type
busybox in the Console dialog box. You can find complete
documentation on command syntax at
www.busybox.net.
BusyBox combines scaled down versions of many common UNIX
utilities into a single executable. The utilities in BusyBox generally
have fewer options than their full-featured GNU counterparts;
however, the options that are included in BusyBox provide the
expected functionality and behave very much like their GNU
counterparts. Most BusyBox commands support the
-h option to
provide a terse runtime description of their behavior.
Using shell commands
Shell commands provide for administration of user management. Use
the Console dialog box for this purpose. User management shell
commands include:
■ addgroup
■ adduser
■ chgrp
■ delgroup
■ deluser
■ passwd
■ chown
■ su

Web browser
The HP Compaq t5515/t5525 thin client image includes the Firefox
Web browser with JRE (Java Runtime Environment). For more
information about creating a Firefox connection, see “Firefox
connection” on page 2-15.
HP also includes an integrated Adobe Acrobat reader for viewing
PDF files on the t5515/t5525.
Citrix
The Citrix (ICA) program allows you to set up and configure Citrix
ICA client connections.
For more information about creating Citrix connections, see
Chapter 3, “Citrix.”
HP Connection Administrator
HP Connection Administrator allows you to manage server and
application connections by setting up Web, RDP, XDM, ICA, and
other types of connections, setting up user accounts, and assigning
connections to users.
Introduction
For information about setting up connections, see Chapter 2, “HP
Connection Administrator.”
VNC viewer
The VNC viewer dialog box provides connection to a VNC server.
The VNC viewer allows control of the desktop environment of
another thin client, PC, or server that has VNC service running. For
information about allowing control of the thin client by another unit,
see “VNC Shadow” on page 4-6.
Administrator’s Guidewww.hp.com1-7
Introduction
VNC server
the VNC server is available only on the t5515 and t5525.
✎
Virtual Network Computing (VNC) is a remote control program that
allows you to view and interact with one computer (the “server”)
using a simple program (the “viewer”) on another computer anywhere
on the Internet. The VNC Server runs as a service and therefore is
available even when the user is logged off the thin client.
The system stores the VNC server password in encrypted form in a
hidden directory named “.vnc” in the user’s home directory. For
example, the system stores the password for user “fred” at:
/home/fred/.vnc/passwd.
If you delete the passwd file to reset the password, the system
prompts the user for a new password the next time the VNC server is
started. The password must be six to eight characters long.
Additional information about VNC server features is available at:
http://www.tightvnc.org
XFce Settings Manager
The thin client includes a control panel called XFce Settings
Manager. You can access a wide variety of utilities from the settings
manager. For more information, see Chapter 4, “XFce Settings
Manager.”
HP Desktop Options
The thin client features different desktop interface options. These
options provide different ways for you to manage your connections,
and as well as determine the appearance of your desktop. Your
selection in this utility determines what your thin client looks like and
how it communicates.

This chapter provides an overview of the Citrix (ICA) program. For
more detailed help in configuring the Citrix client, see the Clients for UNIX Administrator’s Guide at:
The HP Linux thin client allows for the loading of different startup
shells or user interfaces when the thin client boots. One of these shells
is the Citrix ICA client.
You set the Citrix ICA client as the default shell for a variety of
reasons. For example, you may require access to features, such as
Citrix ICA PNAgent capability, that are not accessible from HP
Connection Administrator.

Frequently Asked Questions
System Administrator
How are users managed?
A System Administrator creates new user accounts and assigns users
to groups. The image provides the System Administrator with two
different methods to manage users:
■ The User management utility, accessible by clicking Settings >
User management.
■ Standard command-line tools to manage users - all from the

using command line names and option switches.
How do you prevent a user account that is set to
auto logon from being logged in?
Press the left Shift key as soon as the login screen displays.
How are groups created using BusyBox?
The System Administrator uses the addgroup command to create a

addgroup command overview follows:
How are file permissions handled using
BusyBox?
The Linux operating system uses file permissions as its basis for
security. A Linux operating system considers all resources and
directories as files within the security structure. File permissions
determine each file’s read, write, and execute permissions for all users
and groups on the system. Under Linux permissions, these are in
three groups - owner, group, and others. Each group has three
permission options - read, write, and execute.

./hprepset (without
parameters) and follow the listed options.
How do you synchronize the BIOS and system
time?
To synchronize the BIOS and system time, use the hwclock
command. This command allows you to either synchronize the BIOS
time to the system time, or synchronize from system time to BIOS
time. This command without any parameters displays the current date
and time.
-wSet the hardware clock to the current system time
-uThe hardware clock is kept in coordinated universal time
-lThe hardware clock is kept in local time
How is the VNC password reset?
The system stores the VNC server password in encrypted form in a
hidden directory named “.vnc” in the user’s home directory. For
example, the system stores the password for user “fred” at:
/home/fred/.vnc/passwd.
If you delete the passwd file to reset the password, the system
prompts the user for a new password the next time the VNC server is
started. The password must be six to eight characters long.

Can you capture and deploy settings separately
from an image?
Yes. HP has developed custom scripts for Altiris that capture system
settings and defined HP Connection Administrator connections from
a source HP Compaq Linux thin client system through the Altiris
deployment console. You can then deploy these captured system
settings and connections out to a target HP Compaq Linux thin client
system through the Altiris deployment console. For more
information, see the white paper entitled, “Altiris Manageability
Scripts for HP Compaq Linux Thin Clients” at
Are there other management methods available
from HP to manage HP Linux thin clients?
Yes. Beginning with Linux image verson L1ST3149, L3ST3149,
L4ST3149, you may update images using new HP FTP image update
and DHCP image update for HP Linux thin clients. For more
information, see the white paper entitled, "FTP/DHCP Image Update
for HP Linux Thin Clients" available on the
support site.
