Using Windows Cloud Instance

If you are using TIGER from a Windows OS, you can find information here about; accessing TIGER while you are now connected to OSU's network, logging in and out of

TIGER, starting programs, saving files, and getting data into the cloud.

• Access Outside OSU Network

  If off campus or otherwise not connected to the OSU network, connect to the OSU VPN.

  • Log into https://osuvpn.okstate.edu/ with your OKEY credentials

  • Install the Cisco AnyConnect client

  • Open AnyConnect client and connect to osuvpn.okstate.edu

  • Once logged into AnyConnect and the VPN connection is established, you can access TIGER resources as if you were on campus

• Logging In

  To log into system:

  • Connect to the cloud VMs by using a Microsoft Remote Desktop client (Use the computer names provided in your Cloud setup email.)

  • Log in with your OKEY username and password.

  • If prompted the first time you log in to trust a script “\\storage.c\netlogon\login.cmd”. Choose the “yes” option as this is the login script for the cloud VMs.

    • NOTE: You should only see the warning the first time you log into a particular VM.

• Starting Programs

  • Click Start Menu

  • Click down arrow in lower left corner to get the programs list.

  • The following programs can be launched from the start menu at this time:

    1. 7-zip

    2. Anaconda (python)

    3. ArcGIS

    4. Matlab

    5. Notepad++

    6. PuTTY

    7. PyScripter

    8. R

    9. RStudio

    10. SAS

    11. WinSCP

• Saving Files

  After the login script runs, several network drives will show connected within the VM.

  • The “H:” drive is your campus drive provided by IT.

  • The “K:” drive stores programs/files that don’t have to be installed locally on the cloud VMs.

  • The “L:” drive is your private storage area. This is where you should save your files by default.

  • The “M:” drive is a group storage area. This is where you will need to put files to be shared with other users. We can create folders here for each group/project that needs one.

  NOTE: Be sure to save all important files to either the L: drive or the M: drive. Do not save important files in the “Documents” folder, the Desktop, or anywhere else on the C: drive.

• Logging Out

  It is important to log out when done using a cloud VM so that it will be available for other users.

  Closing the remote desktop window does not log users out.

   

  To log out:

  • Click the start menu

  • Click your name

  • Choose "Sign out".

• Getting Data Into the Cloud

  • Remote Desktop Client (The simplest but also slowest method – only recommended for small files/datasets)

    1. Before clicking “Connect” in remote desktop, click “Show Options”

    2. Click the “Local Resources” tab

    3. Click the “more” button and check the “Drives” option

    4. Click “OK”. Click “Connect”

    5. The drives from your computer will appear in the cloud VM.

  • GLOBUS (Use this option for large files/datasets.) - Step by Step instructions located HERE

Using Linux Cloud Instance

If you are using TIGER from a LINUX OS, you can find information here about; accessing TIGER while you are now connected to OSU's network, logging in to

TIGER, saving files, and getting data into the cloud.

• Outside OSU Network

  If off campus or otherwise not connected to the OSU network connect through VPN.

   

  To use the VPN:

  • Log into https://osuvpn.okstate.edu/ with your OKEY credentials

  • Install the Cisco AnyConnect client

  • Open AnyConnect client and connect to osuvpn.okstate.edu

  • Once logged into AnyConnect and the VPN connection is established, you can access TIGER resources as if you were on campus

• Logging In

  To log into system:

  • You can connect to the Linux cloud VMs by using secure shell (ssh).

  • Log in with your OKEY (short name) username and password.

• Saving Files

  • Save all important files under either "/data/users/okey_short_username" or "/data/groups/groupname"

    • NOTE: Do not save important files in the home folder, the Desktop, or anywhere else outside of “/data/users”

• Get Data into Cloud
  • scp - Use an scp program to copy files to the VM. The path to your private storage space on the cloud VMs will be “/data/users/okey_short_username”.
    • Example (pscp): pscp -scp some_local_file okey_short_username@vm:/data/users/okey_short_username/
  • GLOBUS (Use this option for large files/datasets.) Step by Step instructions located HERE.
    

Cloud File Transfers

Globus

• Globus is an online service to facilitate fault tolerant large data transfers. The OSU Research Cloud is setup as an 'endpoint' with the name 'okstate#cloud_dtn'. To use Globus go here.

  • You can set up your computer as the other endpoint by downloading the Globus personal client here.

• Globus can be utilized easily by following these steps:

  1. Create an account with Globus Online.

  2. ​Verify the account and login to Globus.

  3. Find the "Manage Data" drop down menu and click "Transfer Files".

Log in to Globus with OKEY credentials

• The endpoint for files on the Cloud is: 'okstate#cloud_dtn'

• Authenticate to access this endpoint.

  • Enter username in the form of: your_okey_shortname

  • Password will be your OKEY password

• Set your path to: /data/users/your_okey_shortname

• Once both endpoints are entered correctly, clicking one of the arrows will commence file transfer.
