NOTE: Wireless connections for SSH connections must use the UARK Wi-Fi network. The UARK Guest Wi-Fi will not work!
- Check which version of Mac OS X you are using.
(Apple menu at top left. Choose About this Mac)
- If you are running OS X 10.8 or newer, you will need to install X11 support by downloading and installing XQuartz. As you will see from the XQuartz web page, most earlier versions of OS X already have the X11 support installed.
- Once XQuartz is installed, to insure settings are in place, log out and log in again (or restart).
- Open a terminal as you would normally, type the ssh command to connect to turing, but add the -X (dash capital X) option to your command,:
ssh -X firstname.lastname@example.org
(of course with your own username, of course, ahead of the @ symbol)
NOTE: if you get an error about no trust, etc. you should try using the -Y option instead of -X, thus: ssh -Y email@example.com
- Once logged into Turing, type the command gedit to start this editor.
Tip: if you type the command followed by an ampersand (e.g., gedit & or firefox &) you will not only start the program, you’ll also get your prompt back for use for shell commands.
NOTE: Acxiom lab machines are already have the software, but you do need to follow setup steps.
For command line access, only a secure shell client is needed. The preferred choice supported on our campus is PuTTY). In addition to the shell client, users can configure settings to provide graphical programs using X forwarding. For this you must also install an X server program.
- PuTTY download here
- PuTTY User Documentation here
- The X server application is called Xming can be found here.
(Xming information page – here. )
Setup PuTTY SSH Client
- After installing PuTTY, run the program. You will presented with a screen similar to the one above.
- Type “turing.csce.uark.edu” in the “Host Name (or IP Address) box and leave the port as 22
- Navigate to Connection->Data->X11 to enable X11 forwarding
- Navigate back to the main page and type in a name for this configuration (“Turing” works fine) and click save.
- Click Open, the program may ask you to save an RSA key, just click yes or continue.
If you need more details, look at the section about “Windows Installers” at the link here: http://www.straightrunning.com/XmingNotes/#head-13
How to Use X-forwarding with Xming
- SSH to Turing and login as usual, then try a graphical program like xclock to test that xming is running. Just type xclock at the prompt and press enter. If a graphical clock pops up on your screen, you’re good to go! If not, and you get a “can’t open display” then Xming may not be running. From your start menu or desktop icon run Xming, then re-start the Secure Shell session.
Note: When you startup Xming nothing seems to happen, but the XWindows service or process will have started in the background. When you close the xclock graphical program, you’ll be returned to your turing prompt. You can also run graphical programs in the background like such:
- gedit &
- netbeans &
- Open a terminal, type:
ssh -X firstname.lastname@example.org
where username is your own actual UARK username.
- Type in your password when prompted, and you’re good to go.
- Try it out with programs like xclock, netbeans, eclipse, etc.
TIP: Put a space and then an ampersand (one of these &) after your command, e.g.,
xclock & and you get to keep an active shell prompt in your terminal.
For Mac, Windows and Linux we recommend FileZilla. Clients for these platforms are here: https://filezilla-project.org/
