The most important webpage l.jpg
The most important webpage

  • The Computer Center web page is your friend - http://cc.jlab.org/

  • Most references are on the above web page


Before we begin l.jpg
Before we begin…

  • In Windows, there are several ways to do the same thing, so the way I am showing you is not the only way, but is the simplest way I know.

  • All examples are based on Windows XP


Get to know your computer l.jpg
Get to know your computer

  • System Properties will show you Operating System Information, Registration and Computer Information

    • Right Click ‘My Computer’ and select Properties. Select a General tab.


Get to know your computer continue l.jpg
Get to know your Computer – continue…

  • What’s my computer’s name?

    • Right Click ‘My Computer’ , select Properties and Computer Name tab.


Network configuration static vs dhcp addresses l.jpg
Network Configuration:Static vs. DHCP Addresses

  • A static IP address is assigned to a specific computer and is only intended for use on that specific computer. If that computer needs to move to a different building, you will need to request a new IP. Requesting one is easy; see http://cc.jlab.org/docs/networks/internal/IPrequest.html

  • A DHCP address (one automatically assigned by the JLab servers to PCs), is being used for mobile PCs, e.g., laptops or PCs used for analysis and moved frequently.

  • All new build systems are using DHCP to get their IP addresses.


Using dhcp l.jpg
Using DHCP

  • If you are going to use DHCP, you must follow the instructions on http://cc.jlab.org/docs/helpdesk/dhcp_info.html

  • If you don’t follow the instructions, your computer will be denied access to the network automatically.

  • If your system is build by automatic build system (RIS (will cover this later slide)), your system is automatically registered.


Find out what my network configuration is l.jpg
Find out what my Network configuration is..

  • Open the Command prompt by Start, All Programs and select Command Prompt

    • or Start , Run and type cmd

  • Type ipconfig /all

  • Demo


Modifying network configurations l.jpg
Modifying Network Configurations

  • Right click “My Network Places” and Properties.

  • Right click “Local Area Connection” and Properties.

  • Select Internet Protocol (TCP/IP) and Properties.

  • Please see; http://cc.jlab.org/docs/services/windows/WinXPconfig.html for more detailed instructions


Using wireless l.jpg
Using wireless

  • You must have a wireless card that will support 128 bit encryption

  • In order to use wireless, you need to obtain a WEP (Wired Equivalent Privacy) key

  • All detailed information is on; http://cc.jlab.org/docs/networks/internal/guide/wireless/wireless_main.html


Being in the jlab domain l.jpg
Being in the JLAB domain

  • All Windows machines must be a member of the JLAB domain.

    • More information on joining the domain is available at http://cc.jlab.org/docs/services/windows/WinXPconfig.html, in the Windows section

  • When your machine joins the JLAB domain, your login screen should look like these:


Login process l.jpg
Login Process

  • During login, at a minimum, your J, K, L and M drives will be mapped. When you open My Computer, those drives should be there.

  • You will, also, see a black box with unread News. You should read all News messages. They contain valuable information such as Computer Center maintenance days, Outage alerts, and much more.

  • If you don’t see your mapped drives or News box, please call the helpdesk (x7155) or submit a CCPR via email to [email protected]



Installing cue supported software new way l.jpg
Installing CUE supported software- New way

  • Go to Start, Control Panel, Add/Remove Programs, Add New Programs.


After joining the domain l.jpg
After joining the domain

  • After your machine has joined the domain, the following will be installed on your system automatically.

    • Systems Management Server (SMS) clients

    • Symantec Anti-Virus Corporate Edition software (Symantec CE is the only approved Anti-Virus software in JLAB, do not install different anti-virus software)

      • We are testing the new version of Symantec CE that includes Spyware & Adware removal tools.


Automated updates windows patches l.jpg
Automated Updates – Windows Patches

  • Software Updated Service (SUS) is used for patching your Windows System.

  • Normally, patches are released once a month by Microsoft, and the Computer Center will deliver them on maintenance day

    • If the patch is critical, they could be delivered on non-maintenance days.

  • When Microsoft releases a patch, Computer Center staff will test each patch to make sure it will work in our environment. When it has passed the test, Computer Center staff will approve the patch through SUS.

  • Upon approval, SUS will deliver patches at 3 AM on following day in the following order:

    • If a user with Administrator privileges is logged on

      • Restart notification  allows the user to initiate the shutdown or postpone it

    • If a user with non-Administrator privilege logged on

      • Restart notification allows the user to initiate the shutdown but not to postpone it.

    • If no users are logged on

      • Automatically restarts the system immediately following installation

    • If the system was turned off during the scheduled installation and missed the update

      • It will install updates 15 minutes after restart.


Automated updates windows application patches l.jpg
Automated updates – Windows/Application patches

  • Currently, SUS can only deliver Widows operating systems patches and does not have reporting features.

  • An upgrade of SUS has just been released (June 6, 2005), called WSUS (Windows Server Update Services) which will deliver OS patches as well as application patches.

  • WSUS will have a reporting functionality.

  • An evaluation of WSUS has already been started.


Automated updates sms l.jpg
Automated Updates – SMS

  • Systems Management Server, SMS, is used for hardware/software inventory, deliver patches and install software.

    • SMS, also, allows CC to remote control client systems for troubleshooting

  • Windows XP has built-in remote desktop and Remote Assistance to get help from different users (i.e. helpdesk)


Automated updates symantec anti virus software l.jpg
Automated Updates – Symantec Anti-Virus software

  • When your Windows system is in the JLAB domain, you get weekly updates to your Symantec Anti-Virus’s virus definitions (more often if we receive notification of new destructive viruses in the wild).

    • CUE PCs are configured to run weekly scans and provide real time virus protection (which scans all files you open or receive via email).

  • Symantec Antivirus CE has three group permissions:

    • Normal (default):

      • Automatic weekly scan – User can not stop it

      • Automatic virus definition update – User can not initiate download

      • Realtime protection on – User can not turn it off

    • Mobile

      • Automatic Weekly scan – User can stop it

      • Automatic virus definition update – user can initiate download

      • Realtime protection on – User can not turn it off

    • Control

      • Automatic weekly scan – not scheduled

      • Automatic virus definition update – not turned on. User’s responsibility

      • Realtime protection on – User can turn it off

  • Users can request to be in Mobile or Control group via CCPR


Symantec shields l.jpg
Symantec Shields

  • If your Norton shield on lower right hand corner looks like this:

    • Good – do nothing

    • Bad – call Helpdesk

    • Very Bad – notify Helpdesk immediately


Spyware adware removal l.jpg
Spyware/adware removal

  • Spyware, also known as adware, is Internet jargon for any data collection program that secretly gathers information about you and relays it to advertisers and other interested parties.

  • You can unknowingly install spyware by installing a new piece of software, most commonly a piece of freeware or shareware (e.g., KaZaA, iMesh, WeatherBug). Many of these programs are intended to track your Internet browsing habits, such as frequented sites and favorite downloads, then provide advertising companies with marketing data.

  • We have a site license of Lavasoft Ad-aware SE Professional to remove spyware/adware.

  • Removal tool can be installed from following earlier slide (Control Panel, Add/Remove Programs, Add new Programs) instruction.

  • The new version of Symantec Antivirus CE will detect/remove spyware/adware, also.


Storing data files safely l.jpg
Storing Data Files Safely

  • Always store your data on the Network drives. NEVER STORE ANY CRITICAL DATA ON YOUR LOCAL HARDDRIVE

  • The Computer Center backs up and protects all files stored in home (J: ), site (K: ), apps (L: ) and group (M: ) directories in real time (well, almost).

  • Within your home directory, there is a subdirectory named J:\Jde. All files stored in or in subdirectories of Jde can only be accessed by you.

  • IMPORTANT: All files outside of JDE can be read by Everyone by default. (DEMO)


Storing data files safely24 l.jpg
Storing Data Files Safely

  • Here’s my thought: “It’s not a matter of ifmy hard drive will fail me, it’s a matter of when.”

  • Files stored on a local hard drive, unless backed up on a frequent and regular schedule by a reliable method, are not safe. They can be destroyed by being overwritten, deleted, infected by a virus, or failure of hardware.

  • Very few people have the time or are willing to make the effort to back up files. We always mean to do it… but it’s rarely done.

    • Remember - Anything stored on Government equipment belongs to government, not you…. so, it’s your responsibility to protect.


Storing data files safely25 l.jpg
Storing Data Files Safely

  • There are two files you’ll need to copy to your home directory fairly often, bookmarks and address books. These save locally by default, and many users find them personally important.

    • http://cc.jlab.org/docs/services/email/import_export_pab.html

    • http://cc.jlab.org/docs/services/email/import_export_bookmark.html


Retrieving data from j k l m drive l.jpg
Retrieving data from J, K, L, M drive

  • If you need to retrieve data deleted for less than 3 days, retrieve it from the ~snapshot directory.

  • ~snapshot is being backup every 1 hour

  • If the data was deleted more than 3 days ago, submit a CCPR and we will get it from tapes.

  • Demo


If you need temporary storage spaces l.jpg
If you need temporary storage spaces…

  • Jlab scratch area is available for you to file storage needs for two weeks; after that, it is deleted.

  • Start, Run and type \\jlabscr\scratch

  • Scratch area is not being backed up, so if you delete a file from the scratch area, it’s gone.


Checking permissions on the fileserver l.jpg
Checking permissions on the fileserver

  • Need to use a special tool called “Secure Access”

  • Can be installed from Jlab-Cue/Client Installed Programs/

  • Demo

  • There are a few folders on the M drive (group) which are using NTFS style permissions

  • The NTFS style group area is created by special request


Checking group membership l.jpg
Checking Group membership

  • Used for assign access rights on files/directory

  • Windows groups and Unix groups are different but they are synchronized

  • Use following commands to find what groups you are in;

    • Windows: net user /domain username

    • Unix: groups

  • Demo


Checking quota l.jpg
Checking quota

  • Fileservers have a limited amount of disk space, so everyone has a disk quota.

  • Users need to check their quota before they start to copy large volumes of data

  • Users can check their quota from http://cc.jlab.org/ , in the Quota Check section
