Samsung Syncmaster 911lt Quick Start Guide

							 You can perform bi-directional mapping between serial devices that are attached to the Thin 
Client (e.g. scanners, serial printers) and the Citrix Servers COM ports. This enables 
programs running on the server to exchange data with the local devices. 
COM Port Devices
 
Select the COM port your device is attached to  from this drop-down box: /dev/ttyS0 stands for 
the local COM1 and /dev/ttyS1 stands for the local COM2. 
 
Firewall
  This “
Firewall ” page allows you to configure ICA connections through a firewall or a SOCKS 
proxy server. (Firewalls and SOCKS proxy serv ers are used on networks to improve security.)
 
  Use Alternate Address
 
If you are using ICA sessions to connect to a specific Citrix server behind a firewall, you have 
to activate this option. The Citrix server (usually) has a different IP in the local network than 
from the outside world. (For details on server configuration, look up the “ altaddr” command in 
your Metaframe admin manual.) 
Connect via SOCKS or Secure Proxy Server  
You can configure the ICA sessions to connect to a Citrix server through a SOCKS proxy 
server or a Citrix Secure Gateway (in relay mode). After enabling the alternate address, add the server in the “ Address List” in the “
Server 
Location ” box of the “
Global ICA Settings ”
To make the 
Secure Gateway  field accessible, the 
Browser Protocol in the 
Server 
Location  tab has to be set to 
SSL/TLS + HTTPS
Auto Reconnect
  The options are self explanatory
 
						

							  
PNAgent
  This “PNAgent” (Program Neighborhood Agent) page allows you to configure and search for 
published applications by Metaframe servers.
 
  Server:
 
You need to provide the IP address of server with which you want to connect. The “ Refresh 
Settings ” or “
Change->Update ” settings will update the settings published by Metaframe 
server. 
Logon Method:  
Here you may want to specify how you want to connect to server. You can select either 
“ Prompt User ” or “
Anonymous Logon ”.

 This page allows you to configure how you want to connect to your Metaframe servers. 
However options are self explanatory. 
Session Options:The page is enabled only when the you have selected your Logon Method as Prompt 
User at Server page.
 
  Most of the options in this page are self explanatory. 
Handling of Keyboard Shortcuts 
 
Translated  applies keyboard shortcuts to the local desktop rather than the remote desktop. 
For example, pressing ALT+TAB switches between all the windows currently open on the local 
desktop, including both local and remote windows.  
Direct  applies keyboard shortcuts to the remote desktop rather than the local desktop. For 
example, pressing ALT+TAB switches between all the windows currently open on the remote 
desktop, excluding any windows open on the local desktop. 
Direct in full screen desktops only  applies keyboard shortcuts to the remote desktop rather 
than the local desktop when the remote session is running in full screen mode. If the session is 
running in any other window size mode, keyboard shortcuts are applied to the local desktop 
rather than the remote desktop. If you select Direct, keyboard shortcut translations are disabled to ensure that the 
keystrokes are applied to the remote desktop.
If you select Direct in full screen desktops only and the remote session is running in full 
screen mode, keyboard shortcut translations are disabled to ensure that the keystrokes are 
applied to the remote desktop.
If you come across any issue with Samsung Connection Manager while configuring ICA 
settings, you can also use  Citrix Connection Manager  by running wfcmgr on command 
line.

  Apart from these options, there also is a Factory Reset option available that is used to reverse any 
unnecessary changes being made by the user knowingly/unknowingly. It replaces the main settings 
and configuration files in the system with the default files that were present at the time of installing the 
OS. 
Upgrade
  It is used to upgrade the STC OS. During the upgrad ation, the user preferences and other  critical 
changes made by the user while operating the old OS  are preserved and are made effective in the 
upgraded OS. 
Firmware can be upgraded over following protocols  
zHTTP  zFTP  zNFS  
The different protocols used here provide different methods of accessing the firmware upgrade files 
present over the network. The upgrade function disables all other functions of the STC, so before 
starting the upgrade utility, the user is supposed to quit all other work that is under progress and 
save all the settings that is wished to be retained after the upgrade. For this, a warning message is 
popped up. On selecting OK in this dialog box, the upgrade process starts, else the upgrade 
process is cancelled. 
Upgrade Using HTTP   
The firmware upgradation file is present in the location specified by the HTTP address. No 
username or password is required for this.
 
Upgrade Using FTP   
The firmware file is present in the location specified by the FTP address. A username and 
 
						

							password has to be provided.
Upgrade Using NFS  
The firmware file is present in the location specified by the NFS share address. No username or 
password is needed. 
The upgrading process displays a warning message before starting the process. This warning 
message is used to remind the user that once the upgradation process starts, there is no way that 
the user can access the STC or the files present on it.

Citrix ICA Client Introduction
  The Citrix ICA Client is the front end used in STC for establishing a connection to an ICA 
Server present on the network. Most of the settings have already been explained above 
ICA 
(Global ICA Settings)  across several pages, so we keep a bit briefer here. Many of the 
settings adjusted in the  ICA (Global ICA Settings)  are the defaults for new sessions. 
The very first source of further details regarding ICA and Metaframe should always be the 
corresponding documentation from Citrix. This manual only gives some general 
configuration hints.
Interface
  The Citrix ICA can be configured by using STC Connection Manager. 
Establishing a New Connection
  In order to establish a new connection to the ICA Server, the following steps are to be 
followed: 
zSelect New... option in the main GUI.  zSelect Citrix ICA Client and ADD.  zSelect the Protocol to be used and enter the Server Location in the form of IP.  zChoose if you want to connect to server for desktop or for published applications.  zOnce this is done, click on the button labeled ... besides the Description and Server 
text boxes. If the server is found, its description will be shown in a separate window. 
Click on the description provided to select the particular server as the default ICA 
Server.  
Mozilla Firefox
  Mozilla Firefox is the first choice browser used in the Thin Client. Because of its superior  performance and reliability, it is the primary browser used to connect to the Internet and browse 
various HTTP as well as FTP sites. It already has  PDF viewer and media player integrated into it, 
thus making it a multi-functional application. 
 
 
						

							 
  Xterm
  Xterm is the terminal used in STC wherein we can execute local commands using a shell. It is the  basic busybox shell that is used in the Xterm as the command prompt. The X-term can be used to 
perform all the functionalities that we can do from the various application GUIs. The terminal can be 
invoked from the start menu, desktop icon, mouse  right click or from shortcut provided on the 
taskbar.
 
 
  We can also perform many functions with the Xterm using the local commands. One of them is to view the contents of a directory using the ls command. Also we can use the commands like cp and 
mv for file management purpose. The Xterm is a shell similar to the Linux Terminal, but with far less 
number of applications. Here is a list of some of the common local commands that can be performed 
on the thin client:
