Troubleshooting Tips

There are 2 ways to power on the monitor.

1. With the “Remote”:
   • The “Remote” is being held at the front desk with the student assistant.
2. Without the remote:
   • There are buttons on the back of the monitor. The location of these buttons can be found using the labels which are in front of the monitor. (See image below)
   • The power button is circled in red. The buttons are on the back of the monitor approximately 3 inches above its label.

Connecting wirelessly to screen share

Once the monitor is on, use the input with AirMedia. This will provide an IP address and display further instructions for students to complete the screen share process.
 

Connecting to Zoom meetings

• Use the input with the Mac PC for Zoom. Be sure to power on the mouse and keyboard.
• The mouse takes appx 3 minutes to sync. Please be patient.
• Be sure to power off the mouse and keyboard once you are done.

The Knight Foundation School of Computing & Information Sciences provides our students with a webspace available to host your own website. Create a directory called “public_html” in your U: drive or UNIX home directory and place the website files in there.

Your website is accessible as:  https://www.aul.fiu.edu/~yourUserName

On Ocelot:

# chmod 711 ~

This sets your home directory world searchable

# chmod 755 ~/public_html

This sets your public_html directory world readable

Did you accidentally delete a file from your home directory (U: drive)? Do you need to restore a file from an earlier point in time? We strongly urge our students and faculty to store your data in your home directory (U: drive). This network drive is backed up regularly and snapshots of your home directory are taken daily every morning.

If you need to restore a file, follow the steps below:

1. SSH to the server where your home directory lives. Generally, faculty, staff, and graduate students are on bear.cs.fiu.edu. Undergraduate students are on buffalo.cs.fiu.edu.
2. For Faculty and Staff and Graduate students – Once you are logged in to bear.cs.fiu.edu, type the following command: cd ../../.zfs/snapshot/n-backup-YYYYMMDD/users/[username] Where YYYYMMDD is the date you would like to go back to and [username] is your username.
3. For Students – Once you are logged in to buffalo.cs.fiu.edu, type the following command: cd ../../.zfs/snapshot/n-backup-YYYYMMDD/homes/[username] Where YYYYMMDD is the date you would like to go back to and [username] is your username.

There you will find your home directory as it was at the time of the snapshot that day. If you would like to restore a file or folder, simply type:

# cp [filename] ~

# cp -r [folder] ~

That will copy a file from the snapshot location to your home directory. If you are copying a folder, you must use the ‘-r’ option.

Send an email to request@cis.fiu.edu and the staff can assist you with resetting your password.

Once your logged in, open a terminal and type ‘yppasswd’.

Once your logged in, press CTRL + ALT + DELETE and select the option that says “Change a password”.

The Knight Foundation School of Computing & Information Sciences uses roaming profiles. Roaming profiles allow a user’s desktop and application settings to follow them no matter which workstation they login to on the domain. This roaming profile is downloaded to the computer when you login and uploaded back to the server when you log off. The reason it takes you a long time to login is that you have a lot of data in your roaming profile.

Your roaming profile lives in a hidden directory in your home directory called “.ad-profile-win10”. In Windows, C:\Users\ is your Roaming Profile. The most common culprits for slow logins are Dropbox and virtual machines. When installed incorrectly, these can add numerous gigabytes worth of data to your roaming profile which translates to a substantial login time.

The contents of this folder should not be modified while you are logged in to a Windows PC. You will need to SSH in to one of our Unix servers and move or delete the offending folders and or files from your roaming profile.

There are two sets of login credentials. One set is for the Windows PCs and Macs and the other is for the Linux machines. If this is your first time logging in to one of the systems, your username is your FIU username. Your FIU username is the first part of your email address before the ‘@fiu.edu’ and in the form: jdoe001. Your password is the standard initial password which is the initial of your first name, followed by your Panther ID, and the initial of your last name.

For example: A student named ‘John Doe’ with a Panther ID of ‘1234567’ would be ‘j1234567d’.

These instructions are specifically for CASE 238 & CASE 234

Step 1. Tap the Crestron display to wake it

Step 2. Tap the Crestron display again to begin.

Step 3. Choose the source you want to work with (desktop, AirMedia, or Aux HDMI)

If you choose Desktop, use the wireless keyboard found under the Crestron display. Be sure to look for the switch on the keyboard on the top right of the keyboard. The keyboard is on when switched to green.

If you choose to use AirMedia, follow the onscreen instructions on the Newline to access it.

If you choose to use your own device, connect an HDMI cable to the part found near the NewLine display. It is approximately two feet from the ground.

Step 4. If you have chosen to use the desktop, and you have the wireless keyboard in hand, you may have to wake the screen up. Press any key on the keyboard. You should now be able to log into the desktop. Please use your KFSCIS credentials to sign in.

Step 5. If you need to use Zoom, visit zoom.fiu.edu with your preferred browser and sign in with your University credentials to download an updated exe.

Step 6. Once Zoom has started your meeting, check that your audio settings have your speakers and microphone set to “Echo Cancelling Speakerphone (TesiraFORTE)”

Step 7. You may need to adjust the angle of the camera. Go to the Crestron display and tap the camera icon at the bottom right of the display. Use the arrows to move the camera to your desired angle and use the zoom-in and zoom-out buttons until you reach the desired effect.

Step 8. When you have finished, be sure to log out of the desktop, switch-off the wireless keyboard, and place it beneath the Crestron display. Tap the red power button on the Crestron display to turn the system off.

If at any point you encounter issues, you can reach out to your friendly neighborhood KFSCIS support team for assistance. We can be reached at request@cis.fiu.edu.

Note: The wall mounted camera is not available if you choose AirMedia or AuxHDMI as a source.

SSH

Windows: Windows users need to download an SSH client first. Students can obtain a free SSH client called PuTTY fromhttps://www.chiark.greenend.org.uk/~sgtatham/putty. Once you have downloaded and installed PuTTY, connect using the following:

Host Name: ocelot.aul.fiu.edu
Port: 22

Click ‘Open’. Once you have clicked open, you will receive a prompt for your username.
Enter your FIU username and press enter. You will then be prompted for your password. Enter your password and press enter.

Note: You may receive a PuTTY security alert saying that the server’s host key is not cached in the registry. Click ‘Yes’ to continue.

Mac: Your Mac comes with an SSH client. Search for ‘Terminal’ in Spotlight.
Type the following command and press enter:

ssh yourUserName@ocelot.aul.fiu.edu

Note: You may receive a warning saying that the authenticity of host ‘ocelot.aul.fiu.edu’ can’t be established. Type ‘yes’. You will be prompted for your password. Enter your password and press enter.

Linux: Your Linux OS comes with an SSH client. Open a terminal and type the following command and press enter:

ssh yourUserName@ocelot.aul.fiu.edu

Note: You may receive a warning saying that the authenticity of host ‘ocelot.aul.fiu.edu’ can’t be established. Type ‘yes’. You will be prompted for your password. Enter your password and press enter.

My login credentials do not work

Make sure you are using your Unix credentials and not your Windows credentials. If you have not logged in to a Unix server before, your username is your FIU username. Your FIU username is the first part of your email address before the ‘@fiu.edu’ and in the form: jdoe001.

If you do not know your FIU username, log into MyFIU, select Main Menu > Campus Solutions Self Service > Campus Personal Information > Email Addresses. You will see your ‘Campus’ email address in the form: jdoe001@fiu.edu. The characters before ‘@fiu.edu’ is your FIU username.

Your initial password is the first initial of your first name, followed by your Panther ID, and the first initial of your last name.

For example: A student named ‘John Doe’ with a Panther ID of ‘1234567’ would be ‘j1234567d’.

Please send an email to request@cis.fiu.edu and we will replace the toner as soon as possible. If it is after 5PM, it may not be replaced until the following business day. In this case, you should print to another printer in another laboratory.

If you have lost any items in the laboratory, you can try visiting the lost and found in CASE 258.

Any found items should be taken to the laboratory managers in CASE 258.
