   -As the above site mentions, you will need **Google two-factor authentication (2FA)** whose code will be the second password in the AnyConnect software. The 2FA code is read from an app that you install on your smartphone.

-==== Method 1: VNC Remote Connection Setup ====
+==== Method 1: VNC Remote Connection Setup (Preferred Method) ====
 You can use a [[vnc_install|VNC client]] with X11 forwarding over ssh to access the servers. A VNC remote connection is slightly tedious to setup the first time but infinitely more stable than X2Go.
+Some of my PhD students successfully use [[https://mobaxterm.mobatek.net/|MobaXterm]] but I haven't explored it.
 -----
 ==== Method 2: X2Go Client Setup ====
-Follow the instructions at [[x2go_install|X2Go Client]] to download and install X2Go client.
+X2Go software is buggy and we have switched to VNC.
+If needed, follow the instructions at [[x2go_install|X2Go Client]] to download and install X2Go client.

-==== Alternative Method: X11 Forwarding over SSH ====
+==== Method 3: X11 Forwarding over SSH ====
-If for some reason X2Go connect is not working, Windows users can use graphics forwarding over ssh by following the link:  [[ssh_X11|SSH X11]]
+If for some reason VNC or X2Go are not working, Windows users can use graphics forwarding over ssh by following the link:  [[ssh_X11|SSH X11]]
-Linux and Mac users can use ssh instead of the X2Go client. Mac users will need to install the [[https://www.xquartz.org/|XQuartz]] software. Use the following command

 <code> ssh -XY [username]@cpeg424.ece.udel.edu  </code>
+You could also try using [[https://www.realvnc.com/en/connect/download/viewer/macos/|MacOS]] version of RealVNC client. Please note that the Mac options haven't been tested by the instructor/TA. Please contact IT helpdesk for help with Mac issues.

+==== Useful Tips on Improving Remote Desktop Performance ====
-==== Useful Tips on Improving X2Go/Xsession Performance ====
  <note tip>For VPN access problems, check if you are using the right VPN client for your OS. Also make sure that you don't have any Firewall blocking VPN access/ports on your personal computer.</note>
-  * If possible, use an Ethernet LAN connection at home instead of accessing Cadence over the Wireless LAN. Wireless LAN in a dense urban environment offers lower throughput due to interference and due to the protocol overheads. A slow WLAN connection may drop a user session, make X2Go freeze up, and you may lose your work.

   * There are some Ethernet-to-USB adaptors on the market which can be used in laptops that don't have an Ethernet port.
-  * When you log off X2Go, use System-Log Off from the top menu bar. Otherwise your session will be in a suspended state on the server and when you connect the next time it may create issues. In case that happens, "terminate" the prior session by clicking on the corresponding symbol in the GUI.  After this you will be able to create a new session.

   * Please keep saving your work and occasionally take backups using FTP. The ECE IT Admins may reboot the Server every Friday midnight.
-  * In case of issues, please post on Piazza and somebody would be able to help.
 <note tip>Its a good idea to save your files and take regular backups. It is recommended that you take FTP backups (e.g. using bitvise sftp or Filezilla) from the server on your personal machine (or mail to yourself).</note>
