Remote access instructions for the Meliora 178 computing classroom
Preface
I'm Chris Freemesser, the IT Manager for Brain & Cognitive Sciences.
To allow you to complete your coursework for this semester we've configured the Meliora 178 computing classroom so you can access the computers in the lab remotely. If you experience any problems with the system please email me directly at "cfreemes@ur.rochester.edu" for assistance.
When using this system please act responsibly and be respectful of your other class members. Abuse of the remote access system will result in increased security restrictions that may restrict/prevent your ability to access the classroom.
How this works
There are two steps to the process:
1) You need to connect to the UR network, either locally (if you're on campus) or via VPN (if you're off campus)
2) You will remotely control one of the computers in the lab using VNC (Virtual Network Connection)
Both steps require you to perform some basic configuration on your personal computer.
Step 1 - network connectivity
If you're on-campus and connected to the UR network (either through an Ethernet connection or a wifi connection to a NON-GUEST UR wifi network), then proceed to Step 2. If you are off-campus, you need to make a VPN connection to the UR network. You cannot connect to the classroom through any UR guest wifi network.
Virtual Private Network, or VPN, allows you to securely connect to a remote network (in this case the UR River Campus network). If you don't already have your computer configured for a RC VPN connection, please follow these instructions for enabling VPN & Duo authentication:
https://tech.rochester.edu/services/remote-access-vpn/
Step 2 - Installing VNC & remotely connecting
VNC Viewer is a free app that allows you to remotely control another computer. You will use this to remotely control one of the computers in Meliora 178.
1. Go to https://www.realvnc.com/en/connect/download/viewer/ and download the correct version of VNC Viewer for your operating system
2. Install the program on your computer...the installer is straightforward with no options to choose.
3. Run the "VNC Viewer" application.
4. The VNC Viewer application has field for you to enter the address of the computer you want to connect to. Each computer in Mel178 has an address equal to:
128.151.170.x
Where "x" is a number between 66 and 85 inclusive.
* 66 through 80 are assigned to computers that can only be used remotely...these are the preferred addresses you should try using first.
* 81-85 are for computers that can be used both remotely and in-person and should ONLY be used if 66-80 are all currently in use.
* 85 does NOT have Prism installed.
Pick an address within the appropriate range (for example, 128.151.170.74), enter it into the field, and hit Return.
5. VNC Viewer is going to complain that the connection isn't secure. Checkmark the "Don't warn me about this again" box and then click the Continue button.
6. You will now see a login box...enter "bcsuser" for the username. The password should be provided to you by your instructor.
7. If everything went well, the desktop of the lab computer should now appear. The login credentials for the computer itself are the same as for the VPN connection.
PLEASE NOTE: It is possible for multiple people to remotely connect to a computer simultaneously. If you log into a computer that somebody else is using, please be respectful and disconnect your VNC connection IMMEDIATELY.
8. When you are done using the lab computer, please close whatever program you were using and simply close your VNC window. Do *not* use the Sleep/Restart/Shutdown/Log Out" commands under the Apple menu on the lab computer!
Troubleshooting
If you are unable to connect to your assigned computer via VNC...
1) Make sure your computer is either plugged into a UR wired network, is on a UR non-guest wifi network, or that you are connected to the UR network via a VPN connection from off-campus. If you are on a UR guest wifi network or you are off-campus and are using a plain Internet connection without VPN, you will not be able to connect to the classroom.
2) If you are connected to the UR network via VPN, open the Cisco VPN client and click on the gear icon to go into the client's settings. There's a checkbox in the preferences for "Allow local (LAN) access when using VPN". Make sure that is NOT checkmarked....if it is, UNcheck it, disconnect your VPN session, restart your computer, then reconnect via VPN and try again.
3) The specific computer in the lab you're trying to connect to may have gone offline. As a test, try connecting to a different computer in the lab (valid addresses are 128.151.171.66 through 128.151.171.85, inclusive). If your assigned computer is the problem, please contact me (cfreemes@ur.rochester.edu) so I can remedy the situation.
