CAEDM Resources

VPN Policies:

Connecting to the CAEDM VPN establishes an encrypted link between your device and CAEDM's network. Thus, while connected, your device has access to CAEDM resources and acts as if it were plugged into the department and university network. Of course this means that devices connected via the VPN are still required to maintain CAEDM technology and connection policies.
Most CAEDM resources can be used form off-campus without using the VPN. However, certain resources needing additional security and/or licensing must be connected to the department network. Thus, the VPN is necessary in these situations. Examples are:

• Workstations used by researchers, faculty, and staff
• License servers
• Free access to the HBLL's subscription services (Compendex, EBSCO, RefWorks, IEEE Xplore Digital Library, and Proquest Safari Books Online)
• Content-filtered internet access
• Other campus computers or services protected from public internet connections

Connecting to the VPN:

IKEv2 (Internet Key Exchange v. 2)

This is the preferred VPN connection protocol as it is the most simple and preinstalled for most operating systems (Windows 7 and newer, MacOS 10.11 and higher, and is available for non-preinstalled operating systems for Linux, Android, iOS, MacOS versions lower than 10.11). However, this protocol may experience connectivity issues in large, crowded places due to heavy virtual traffic. In such situations, SSL VPN may help.

SSL VPN (Secure Sockets Layer Virtual Private Network)

Certain internet providers may not allow IKEv2 VPN connections as well. In this case, SSL VPN client may be downloaded for Windows, Mac OS X, iOS, and Android.

Clientless SSL VPN

Without the need to install or configure software, a web browser is used for more basic services and content-filtered browsing.

All three examples of connecting are listed in the instructions below:

Troubleshooting:

• When using software install on a personal computer that require a license server, make sure to include et.byu.edu extension.
  
  • Ex) If Wizbang 2000 requires a license server to run, normally that license server may be set to look like "1234@licserv". However, when using the VPN, it needs to be "1234@licserv.et.byu.edu". This extension will work fine on-campus and off-campus, so you could always have the license with the added extension.
• Do not use split tunneling.
• If the VPN provides the error "Parameter is incorrect," see this solution prior to reaching out to any CAEDM employee.

J:Drive

Each CAEDM account and group has a separate network fileshare space to save files and access them on your own time. Each J:Drive fileshare space is backed up and limited to a 10gb quota. Coming close to that 10gb cap may result in an inability to sign-in to any lab computer with a Linux OS. This issue arises because Linux systems store all user data on the Linux user's J:Drive directly. Thus, without adequate space, a user cannot sign-in to Linux systems because of limited space in their J:Drive folder.

J:Drive usage, both personal and groups spaces, can be viewed via the main CAEDM website by using the "Files" tab and selecting "My Disk Use".

More information on quotas can be found on the CAEDM website.

User Folder:

Personal folder linked to one's CAEDM account. No other user may access this saved space. Again, each user has the typical quota of 10gb, which is ample space when coupled with Box.

Groups Folder:

The "groups" folder within the J:Drive contains any shared folders between CAEDM users. All CAEDM users can create a group, which is placed in the "group" fileshare space by default. Do NOT delete or rename the "groups" directory, as well as save any documents within the main "groups" folder, only in subfolders that are shared.

On-Campus Access

Windows

Default locations:
- All CAEDM Lab spaces
- Most department labs a part of the Ira A. Fulton College of Engineering and Technology
- RGS Blade workstations using the CAEDM HP/SAM client
- Citrix applications

Built into Windows is the procedure to "map" a network drive. Mapping enables the J:Drive to be treated almost like any other drive on your computer, like a USB or C:Drive. Thus, streamlining and improving efficiency in terms of accessing the J:Drive.

This PC/My Computer Method:
1) Right click "This PC" (Windows 10) or "My Computer" (Windows 7) and select "Map Network Drive...".
2) Select j: as the drive in the "Drive" box.
3) Type in the "Folder" box \\fs-caedm.et.byu.edu\YOURCAEDMUSERNAME
4) Select "Connect using a different user name".
5) Enter "CAEDM_AD\" and then your CAEDM user name and password. For example: "CAEDM_AD\engineer1" (without the quotes)
6) Click "OK" and then "Finished".

Command Prompt (CMD) Method:
1) Use the 'net use' command with server 'fs-caedm.et.byu.edu'.
2) It should look like "net use j: \\fs-caedm.et.byu.edu\username"

To unmap the J Drive, do the following:
1) Right click "This PC" (Windows 10) or "My Computer" (Windows 7) .2
2) Select "Disconnect Network Drive...".
3) Select from the list of network drives "J:".
4) Click "OK".

If you are using a laptop computer, keep in mind that BYU Guest wireless and other on-campus networks may not currently support mapping your J Drive. The easiest thing to do is connect physically by ethernet to BYU's network or to BYU Secure wireless if you wish to map your J Drive to your computer.

*If you receive an error like "The specified network password is not correct." then you need to take the following steps:
1) Go to Run (Windows + R) and type secpol.msc. Hit enter.
2) Navigate to Local Policies > Security Options
3) Double click on Network Security: LAN Manager Authentication Level
4) Select "Send NTLMv2 response only. Refuse LM & NTLM"
5) Click apply. Then, try mapping the drive again.

MacOS

Mapping a Samba Drive:
1) Select the Finder
2) From the top menu, select go > connect to server.
3) In the window type the following: smb://fs-caedm.et.byu.edu/YOURCAEDMUSERNAME
4) Click 'Connect'
5) A screen will pop up prompting you for your username and password. Enter the info you'd use to log into a CAEDM lab computer.
Done! You can access your J Drive files straight from your Mac's finder.

Linux

Nautilus:
1) In Nautilus (An app called files on most linux distributions) select "Other Locations" from the left bar
2) In the "Enter server address..." bar at the bottom type "ssh://<username>@ssh.et.byu.edu"
Terminal:
1) Enter the command "ssh <username>@ssh.et.byu.edu"
2) When prompted, enter your password.
SAMBA:
1) In the "Enter server address...' bar at the bottom type "smb://<username>@fs-caedm.et.byu.edu/homes/"

Off-Campus Access

To access the J:Drive, you must establish a gateway to access the J:Drive remotely using the CAEDM VPN. This allows you to map and use your J:Drive as if you were physically on-campus. This also allows you to use most on-campus software and resources.

NOTE: Accessing your J:Drive on your own computer from on- or off-campus is significantly slower than using CAEDM lab machines. If you can, try doing large file transfers on lab machines.

Backups

All user data not stored in the 'scratch' directory is backed up nightly. To restore lost data from the tape backup, use the CAEDM WebRestore tool accessible from the "Restore My Files" option in the "Files" menu of the CAEDM website.

Using a Personal Computer with CAEDM:

Software and Hardware Requirements

Using CAEDM services remotely requires client software, on compatible hardware. All CAEDM client software is easy to install on Windows, and is easy to use. Accessing the J Drive from off campus on all platforms will require using SCP or mapping a drive through the VPN. On-campus access is readily available on any computer by mapping the J drive directly. There is Citrix client software available for Linux and Macintosh, but installation may be more difficult, and the client software is not as polished.

*The necessary software is probably already on your computer.

Applications

ZCentral Remote Boost
HP ZCentral Remote Boost (formerly known as HP RGS/Remote Graphics Software )

ZCentral Remote workstations support graphics-intensive applications such as CAD or 3D modeling. RGS clients are available for Windows and Linux, and access is available both on and off campus. RGS workstations do not include less graphic intensive software such as Microsoft Office; use Citrix to access such software.

For detailed instructions on how to set up ZCentral on a personal computer, click here.

Citrix
Citrix allows a laptop, tablet, or even phone to remotely run most software available in the CAEDM labs through a web interface. Citrix is used for programs that don't require 3D graphics, such as Microsoft Office or MATLAB.

For detailed instructions on how to set up Citrix on a personal computer, tablet, or phone, click here.

SSH
SSH provides a remote command shell to a Linux workstation. It can be used to modify files, run command line applications, and even run limited graphical applications.

For detailed instructions on how to set up SSH on a personal computer, click here.

LabConnect
LabConnect was created in answer to the increased demand for remote computing in response to classes being taught online (Mar 2020-Aug 2021) due to the COVID-19 virus. Now that classes are being held on-campus once again, LabConnect is available but with fewer computing resources. LabConnect allows users to directly connect to college and department lab machines remotely from off campus. Check with your individual department to find out which labs are available via LabConnect.

J:Drive Access

The J Drive is a convenient place to store files. It provides a generous amount of space, and it's backed up every night. It is available without any setup from the labs, on RGS workstations, and inside Citrix applications. You can also map the J Drive, making it accessible on-campus just like the C drive, or use SCP to simply transfer files to and from the J Drive.

Printing

Printing to any CAEDM printer from a personal Windows or Linux computer is easy using the CAEDM Print Driver. The driver enables printing to all CAEDM printers from anywhere on campus.

Network Requirements

The university provides wireless internet in most buildings on campus. BYU Guest Wireless severely limits functionality and will not work with most CAEDM services. All CAEDM services function properly over Eduroam. The laptop stations in the CAEDM labs have a wired connection to the campus network that support all CAEDM services.

Free Software

CAEDM also provides free access to download Microsoft and VMWARE software to your own computer. The Microsoft Developer Network Academic Alliance or MSDNAA and The VMWare Academic Program allow students, faculty, and staff of the College with CAEDM accounts to download software programs for academic related non-commercial purposes. MSDNAA provides Windows operating systems, compilers, server software and much more. The VMWare Academic Program offers software to help create and manage virtual workstations and servers. There is software compatible with Windows, Linux and Macintosh operating systems.
