• Backup Time @ full load= 3.2 minutes

• Surge energy rating= 365 Joules


New Operating System

• RHEL 5.4–Faster (supports 64-bit processing)

–No longer necessary to periodically reboot the workstations

–TFMS application (TSD, NTML, FSM, etc.) functions remain unchanged

–Slight differences in window and desktop menu appearance

–New Firefox browser


Tech Refresh Enhancements

• To relieve site personnel of repetitious system or troubleshooting activities, many support functions are now automated or performed by the SMCOs at the TFMS Consolidated Service Desk:– Included are all SUP mode script functions and anything requiring

“Root” password

–Onsite SA and TO staff may be asked by the SMCOs to assist with activities such as fileserver swaps, HW/SW diagnostics, workstation reboots, etc

–Hewlett Packard Open View Operations (HP OVO) agents will be installed on the new workstations and fileservers. OVO provides automated monitoring and will deliver 24x7 equipment status information to the SMCOs


Tech Refresh Enhancements (cont.)

• To enhance system security, the new equipment does not support removable media such as CDs, DVDs, or thumb drives. A new FTP process will be covered later

• To provide system stability, a Redundant Array of Independent Discs (RAID) has been installed on all servers and workstations–One drive will function as the primary

–The secondary drive will be updated regularly to mirror the primary drive

– If the primary drive fails, the secondary drive automatically takes over the primary function

–The SMCOs will be alerted by the OVO agent and will contact HP for a replacement drive


Tech Refresh FAQs

• Desktop FAQs–The panel bar can be hidden, but not moved as it could be in the old

operating system

–The RHEL Applications, Places, System, TFMS, and browser launcher menu icons are locked on the panel bar and cannot be moved, hidden, or deleted. All other icons can be moved

–There is only one screensaver – a blank screen. Adjust the time limit for screensaver activation using the System menu

–Fonts for individual applications can be changed. System-wide font changes are made from the System menu on the panel bar


Tech Refresh FAQs (cont.)

• Desktop FAQs–Windows can be rolled up/down with a double click

–The workspace switcher looks different by default. Right click on it to access the preferences to put names on the workspaces, rearrange them in stacked rows, or add more workspaces

–Workstations have an onboard speaker. On the right side of the GNOME panel there is a speaker icon. Click on the icon to open up a dialog box to mute or adjust the volume as needed. To check the sound level, open a terminal window and press the backspace key to force a beep



• Web Browser FAQs–The browser for the TFMS workstation has changed from Sea

Monkey to Firefox

–SeaMonkey was a web browser and an HTML editor, while Firefox is strictly a web browser

–The items on the Firefox menu bar differ from SeaMonkey

–The Globe launcher on the panel bar was configured to start a single browser

–You can also use the Applications menu to open a browser



• Web Browser FAQs–The Globe launcher on the GNOME panel was configured to start

only a single browser window, but you can add your own launcher to the panel bar and use it to open multiple windows

–To add your own launcher to the panel bar, click on Applications, Internet, Firefox Web Browser, right click on Firefox Web Browser, and choose Add this launcher to panel



• Printer FAQs–The new printers can perform duplex printing. For individual jobs,

you can choose the 2-sided option from the Page Setup tab in your print property options

–Your NTML SA may have to edit the PRINT_MODE keyword found in the NTML configuration file and change the option to postscript to successfully print your logs

–To change the printer defaults, please call the TFMS Consolidated Service Desk



• System Admin FAQs–The Remote Access Commands like rlogin have been replaced with

the Secure Shell Commands (slogin, scp, ssh, etc.) to provide a more secure operating environment

–Files can be copied from one workstation to another using the secure shell commands

–The NTML and TSD configuration files are located in the same directories as in the old system. They can still be edited with a Text Editor, such as gedit or VI



• System Admin FAQs–NTML and TSD configuration files can be still copied from one

workstation to another over your local network. Use the secure shell Commands

–The TM Shell tool is no longer available for scheduling CRON jobs . Bur you can create CRON jobs and schedule them from the command prompt in a terminal window

–You do not have to have the ROOT password to create and execute a CRON job


Presenter Note (cont.)

• Places Menu–Access to folders, other drives, and computers on the network

–File Search capability

• Gnome Menu–Access to standard applications:

• GIMP, OpenOffice, Calculator, Text Editors

• Workspace Switcher–Workspace names can be user defined

–User can add/subtract workspaces

–Has Help and can be moved on panel bar


Presenter Note (cont.)

• Panel Bar–Locked, standard menus cannot be deleted or changed

–Users can add applets to the panel, e.g., notification areas and launchers

• Workspace Right Click Menu–Options no longer accessible in 5.4:

• New window

• Scripts

• Disks

• Use default background

–Options renamed in 5.4:

• New folder

• New launcher


Working with RHEL 5.4

• Customizing the GNOME Desktop–The panel bar

Working with RHEL 5.4


A Tour of RHEL 5.4


The TFMS FTP Process

• The procedure meets all FAA TFMS security requirements and policies

• The FTP process transfers files from the TFMS network to the Administrative / Mission Support network

• Secured TFMS Web Portal servers connect to FTP servers at the TFMS Consolidated Service Desk


The TFMS FTP Process (cont.)

• A Linux script is used to perform the transfer from the local TFMS workstation to the TFMS Web Portal (FTP Server)

• The user runs the script and identifies a file(s) to be transferred

• The script executes a background transfer of the file(s) to the Service Desk where the files are stored on the TFMS Web Portal server

• The TFMS Web Portal server can be accessed from FAA administrative workstations


The TFMS FTP Process (cont.)

• Each site has a folder on the TFMS Web Portal for storing the files uploaded from the TFMS network

• Authorized users to the website can download files to an admin workstation

• A quota of 5 gigabytes per site is the current limit

• Uploaded files are retained for 60 days before they are automatically removed


TFMS Web Portal Server

• File size can not exceed 5 megabytes. The TFMS Consolidated Service Desk can assist with transfer of a larger file

• Executables cannot be transferred

• Weather files cannot be transferred

• Users may set options that effect how the browser displays the download window –To set options to edit the Browser Preferences

• Set options for a default download folder for all downloads

• Set options to display the download manager when a download begins and upon completion


Sending the File to the FTP Server

• Logon to a TFMS workstation

• Open a terminal window

• Change the directory to the directory where the file is located

• Identify the file to be transferred

• Transfer the desired file by typing the following:

upload <filename> Enter


Retrieving the File from the FTP Server

• Connect to the TFMS Web Portal from an Administrative / Mission Support workstation

• A Web Portal Page menu entry link is displayed on the Admin user’s page for the Admin File Downloads


Retrieving the File from the FTP Server (cont.)• Select Admin File Download link, which redirects you to the File Transfer Server (FTS) web page

• Select your facility folder


• You have two download options:–Option 1, Download one

file:

–Option 2, Download multiple files:

Retrieving the File from the FTP Server (cont.)


Retrieving the File from the FTP Server (cont.)• Option 1, Download one file: –Double-click file name.

–A browser window opens allowing you to specify a target directory and file name

–Once started the file transfer will initiate


Retrieving the File from the FTP Server (cont.)• Option 2, Download multiple files: –Select one or more files in

the directory list

–Select Download

–A browser window opens allowing you to specify a target directory and file name

–Once started the files will be compressed into a single zip file and file transfer will initiate
