X11 Forwarding over SSH

Use X11 Forwarding on Windows only when you can't get X2Go to work.

There are couple of different SSH Clients available for windows. You can use either Putty or Bitvise clients below:

Download and install Bitvise SSH client from https://www.bitvise.com/ssh-client-download
From your SSH client, connect to cpeg424.ece.udel.edu using the default port (22).
Enter your EECIS username and password when prompted as in the screenshot below.
You can select whether you want to open the sftp window each time you login. Stfp is useful for file transfer
It's a good idea to install a local Xserver on Windows such as VcXsrv or Xming.
To run Cadence, you will need to export graphics display from linux. You can alternatively use X2Go instead of using SSH at all. In the SSH client's Terminal tab, enable X11 forwarding. Use the default display setting: 127.0.0.1:0.0.
Then click on “Login” at the bottom of the screen.
A SSH session will then open up to the course server something like in the figure below:
Use xhost command to allow any hosts to connect to the display.

xhost +

You can start Cadence by using the virtuoso command in the background (append with &)

You should see a graphical window of Cadence command interpreter window (CIW) show up as below. If it doesn't then you probably forgot to use xhost +

You can save this bitvise profile for future use and load it the next time you need to login.

Download and install Putty SSH client from https://www.putty.org/
From your SSH client, connect to Host Name cpeg424.ece.udel.edu using the default port (22).

In the Tab Connection → SSH → X11, Enable X11 forwarding and set the X display location to 127.0.0.1:0.0
Go back to the Session tab, and Save this as a profile.
Click the Open button to initiate your connection.
Enter your EECIS username and password when prompted as in the screenshot below.
