Read the ECE Support instructions.
Since the waveform viewer requires the display of its X window, X forwarding must be handled correctly. Within the ECE department from linux, ssh machinename should work however if it does not, type man ssh to see which options are needed. The key is to enable trusted X11 forwarding.
Common possible options include: -X for correct X11 operation, -Y for correct X11 operation, and -l ECEusername in case your local machine's username is different from your ECE username.
ssh (secure shell) is program and protocol that allows secure logins over insecure networks. Using ssh is the best way to log into ECE machines and work with them from remote computers.
You will need an ssh client and X server to be able to run magic and irsim from a department computer. These applications come standard on UNIX-based systems such as linux. Some helpful links to various programs for other systems are listed at the bottom of this page.
If needed, start your X Server. Refer to its documentation on how to setup "X11 Forwarding". In Linux and HP-UX the X server is always running.
Log into an ECE machine from your local ssh client.
Verify that you can display X11 applications on your local computer.
Putty is a free, robust, and very easy to setup ssh xterm program for Windows.
Download and install Xming and PuTTY from the links below. Installing Xming will require that you first download the executable file (.exe), then install the program.
Putty can also be found from: putty.org > "Download PuTTY here" > www.chiark.greeneend.org.uk > Binaries > LatestReleaseVers > For Windows on Intel x86 > PuTTY > putty.exe
After installation, start Xming from the start menu. It is normal that you will not see any changes. Xming is necessary for applications running on the ECE computers to show windows on your local computer (using the X11 protocol).
Run PuTTY by double-clicking the icon you downloaded.
In the "Host Name (or IP address)" field, type "ComputerName.ece.ucdavis.edu". For example, for "python", then this field should be: "python.ece.ucdavis.edu"
"Port" field should already be "22"
"Connection type" should already be "SSH"
In the left column, click the "+" symbol next to "SSH", then click "X11". Check the box next to "Enable X11 forwarding".
In the left column, click "Session" at the very top.
In the "Saved Sessions" field, type a short name to remember the machine name such as "python"
Click "Save" so you can quickly double-click on python to log into that machine with one simple step.
Double-click on python to log into the machine.
Type in your ECE login and password. Verify your display is working using the tests above. Your Putty terminal window will now behave in exactly the same way as if you were logged into the console of the machine in Kemper Hall.
MobaXterm is another option for a ssh terminal program. Read the ECE Support instructions for MobaXterm. I have not used the it however it sounds like it has very nice features.
From Windows/Putty: follow the instructions given above.
From Linux/MacOS, type:
"ssh email@example.com -X"
for example using the machine "gopher". See "Available ECE Machines" web page for a full list.
Type "xeyes" or "xclock" to verify that your display is working correctly. Type ctrl + c to kill the application.
You can also type "setenv | grep DISPLAY" and verify that a line of the form "DISPLAY=localhost:10.0" is displayed. If neither appear to be correct check your local client settings.
Negatives: Once started, the environment must be run on the same machine. The session window size can not be changed which can be inconvenient if you log into your environment from different machines with different monitor sizes.
