Research Labs

Creating/Renewing CS Research Accounts

Students:

When you join a research lab, you must give your professor the following information to obtain a research account.

  • Full Name
  • 80 Number
  • UTEP Email Address
  • Preferred Email Address

Faculty:

To request a new account for a research student, obtain the information from the student as listed above and send an email to sysman@utep.edu containing the following information:

  • Full Name
  • 80 Number
  • UTEP Email Address
  • Preferred Email Address (If not from UTEP)
  • Key Request Information (If you do not want default. See Below.)
  • Termination Date (Required for Non-UTEP researchers)
  • Windows Account, Linux Account, or both)
  • SVN Access Requests (Site Information Required)

By default, all research accounts must be renewed every semester. All faculty members will receive a spreadsheet at the beginning of the semester that contains information for all their research students so that they can indicate which accounts should be renewed and which should be disabled. Accounts will be renewed or disabled when CSTS receives the revised spreadsheet.

CS Research Lab and Building Access

Chemistry and Computer Science Building

When a new research account is created, CSTS will automatically submit a key request form and a building access form for the corresponding research lab and the Chemistry and Computer Science Building.

Students:

When accepting a key to your research lab, keep the following in mind:

  • You are responsible for keeping your key safe. If you lose the key, you will be financially responsible for re-keying the research lab door.
  • Do not lend your key to anyone. This keeps your research lab secure and your research materials safe.
  • If you leave the research group, you must promptly return your research lab key.
  • If you are graduating, you must return the key regardless of whether or not you will be returning as a Master's or PhD Student. You will not be cleared to graduate until you do so.

Faculty:

When a new research account is created, CSTS will automatically submit a key request form and a building access form for the corresponding research lab and the Chemistry and Computer Science Building. If you do not want this default, then you should indicate this when you request the new research account. If your new researcher is not a UTEP student, staff, or faculty, you will need to purchase an Affiliate ID Card for them for a small cost at the MINER Gold Card Office. This will allow them to use the building access system and pick up a key.

Old Computer Science Building

When a new research account is created, CSTS will automatically submit a building access form for the Old Computer Science Building.

Students:

You need to talk to the professor in charge of your lab to get a keypad code for your research lab door. It will change every semester, so be prepared to ask him or her whenever a new semester begins.

Faculty:

CS Tech Support will send you a new keypad code for your students every semester so that you can distribute it to the students working in your labs.

How to Save Your Work in the Research Labs

The My Documents folder in Windows, which stores "My Pictures," "My Music," desktop, etc, is mapped to a share on the research server (Your H: Drive) and is backed up on a regular basis. Whenever you log into any computer on the SE Domain, your files will be under My Documents. You should always save your files there.

For safety, you should always check to make sure that your My Documents folder is being mapped correctly. To do this, follow these steps:

  • Click on Start, then right-click on My Documents.
  • Click on Properties
  • Examine the window that comes up. Under Target, you will see if your drive is being mapped. The key idea is that if the target is from a server, Deimos2, then all is good. If it comes from the local machine, C:, then something is wrong.

    img1img2

  • If there is a problem with the drives mapping, send an email to sysman@utep.edu with the following information:
    • Your name
    • Your email address
    • Your Username
    • Your Research Group

Remember, it is illegal to store non-research multimedia files on the server (Desktop, My Music, My Videos, etc).

CS Research Account Disk Quota

If you get messages saying that you cannot save anymore, then you most likely have filled your cache. To remedy this problem, follow these steps:

  1. Delete any non-research data you have.
  2. Reduce the size of your cache for all internet browsers to the minimum. For instructions, click here.
  3. Empty your recycle bin (Windows) or your Trash (Linux).

If, after you've completed these steps, you still cannot save, then send an email to cstechs@utep.edu, and provide your username and research group.

Administrator Access on CS Research Machines

If you need administrator access on a Windows machine to install a program, ask your professor for permission. You will need to give him or her the following information:

  • Your name
  • Your email address
  • Your Username
  • The Machine Name (Found on the white label in front of the machine)
  • The machine IP Address (Also on that label)

Your professor will forward this information to us. As policy, we only allow one administrator on each machine. If your machine is taken, and the student is still working on it, then you'll have to choose another machine. If that student is gone, then your professor will need to send us an email saying that we can remove the previous person and grant you access.

Once you get administrator access, we'll give one final warning:

Any files placed anywhere outside your My Documents folder will *NOT* be backed up. If these files are lost, they are gone forever!

You have been warned.

To help safeguard your research files, the CS Tech Support policy limits one administrator per computer. If a computer currently has an administrator, then you cannot have administrator access. The only exception to this rule is when the administrator is no longer in the research group, and your professor approves you taking the former administrator's place or if your professor approves of more than one administrator after understanding the potential risk.

No one will be granted administrator access in any way on a CS Server. There will never be a situation or program requirement where you absolutely have to have administrator access on a server to function properly.

Stand-Alone Windows Machines

If you need a Windows stand-alone machine, you will have to follow these guidelines:

  • You must request a stand-alone image from CS Tech Support. The image includes the following:
    • Windows XP Pro
    • Antivirus
    • Visual Studio Pro
    • Java JDK
    • SSH Client
    • Microsoft Office
  • You must keep up with the Windows Updates and virus definitions at all times.
  • You will be responsible for your own backups.
  • If you want to use remote desktop from outside campus, you'll have to provide a name for the machine so that CS Tech Support can provide a static IP address.
  • This machine will never be part of the CS Windows Domain.

^ Return to Top


Root Access on Linux Machines

You can have root access to a Linux research machine, but you will have to meet the following conditions:

  • The machine MUST be stand-alone. (To safeguard all research users)
  • You MUST provide the root password to CS Tech Support any time it changes. (For security reasons)

If the machine is going to be a member of the CS Domain, then you cannot have root access on that machine. However, we can provide sudo access on that machine based on your needs.

CS Tech support only installs and supports CentOS. All other Linux distributions are not supported. However, you can have a stand-alone Linux distribution, provided that you follow these regulations:

  • You must report the installation to CS Tech Support
  • You must report the machine's name to CS Tech Support
    • If this machine will only be used for a few days, you can skip this step.
    • You will receive a static IP and a fully qualified name under the DNS.
    • Once you complete this step, you cannot change the name of the machine unless you request a change with CS Tech Support.
  • You must configure the firewall.
  • You must keep up with the updates.
  • You must provide the root password to CS Tech Support
  • Root must be disabled from direct SSH
  • You must create a secondary account for daily work. (No using the root account for work)

Sudo Access on CS Research Linux Machines for non-root users

With sudo access, you can install software, change network settings, and configure other software and hardware for your machine. Sudo access is granted by research groups and machine groups. If you find that the command you need are not accessible, you will need to contact CS Tech Support for assistance.

i.e on using sudo

  • To install software, use the command:
    # sudo /usr/bin/pirut
  • Configure soundcard, use the command:
    # sudo system-config-soundcard
  • Mounting a USB flash drive, use the command:
    #sudo mount /dev/sdb1 /media/usb
  • To unmount a USB flash drive, use the command:
    #sudo umount /media/usb

Can't Access Your Stand-Alone Machine From Off-Campus

If you cannot communicate with your stand-alone machine from off-campus, it means that your machine was not officially reported to CS Tech Support. When you report the machine to CS Tech Support, then you will get a static IP address, and the campus firewall will not block the incoming traffic.

^ Return to Top



How to install software in Linux for non-root users

First you must know what version of CentOS is installed on your machine:

  • # cat /etc/redhat-release

If you are running CentOS 5.x

  • # sudo pirut

If you are running CentOS 6.x

  • # sudo gpk-application

Both commands will launch the graphical software installation GUI. This is the recommended method to install or remove software since it will update all necessary files. Do not use YUM or RPM as these applications will not update all the necessary files unless you are ROOT.
