Use common terminal application for command line access See the VPN page for software download and setup instructions. A VPN ensures that all communication between your computer and RC resources is encrypted even when using a public wireless network. If you are using your RC account mainly for access to the SPINAL instrument scheduling software, the VPN and OpenAuth installations described above are not required.ĭownload VPN and install VPN software appropriate for your computerĬluster resources must be accessed through a virtual private network software (VPN) for any off-campus connections. NOTE: SPINAL access does not require two-factor authentication See the OpenAuth Guide for instructions if you have not yet set up OpenAuth.įor troubleshooting issues you might have, please see our troubleshooting page. Unless you’re only interested in using the SPINAL scheduling software, logins to FASRC cluster resources use a two factor authentication scheme that is supported by the OpenAuth tool. See How Do I Get a Research Computing Account for instructions if you do not yet have an account.Ĭluster access requires the OpenAuth tool for two factor authentication If you’re new to the cluster, please see our Quick Start Guide first.Ĭluster resources (storage, software downloads, special workstations, instrumentation scheduling, etc.) can be accessed through a number of paths (see below), but all require an RC account. The following page is a quick reference with links to many of the basics. SSH x11-forwarding sshd_config file "Xorg-x11-xauth " package Export display=:0.0 DISPLAY environment Variables set-up X11 Forwarding over ssh x-server X Window SystemĢ.There are various tasks and options for using the FAS RC cluster. Tunnel x over SSH from OS X Unix terminal to login Far_away_machine (a Linux server) There is a problem or to solve, here are some search terms, the proposed use of Google, the information on Baidu is still difficult to search: Following the actions given above, it is inevitable that problems will occur. Maybe your machine environment and the machine environment I use are not consistent, maybe you have installed more or less installed, I am not sure of these. You may not have x authority installed under your Linux system, please install sudo yum installed Xauthġ. Say more, in order to be more convenient, later you can also execute gnuplot-persist-e "plot sin (x) under the shell. Try the command plot sin (x), and OS X will appear with a new window with a sinusoidal curve above it.ĥ. (Always get this prompt before the configuration succeeds, gnuplot:unable to open display ': 0.0 ' gnuplot:x11 aborted.) You will see a hint like this: Terminal type set to ' X11 ' Under the SSH Terminal Login window you can work under the Linux system, type the command The X11 installed on OS X system will be automatically adjustedĤ. Log in to the Linux system from OS X, you can use the system terminal or ITERM, etc. Without such a setting, you may be prompted when you log in:X11 forwarding request failed on Channel 0ģ. Linux system open x fowarding functionĢ.1 sudo vi/etc/ssh/sshd_config for the following settings: No configuration is required for X11 after installation and no configuration is required for OS X systems.Ģ. X11 is now no longer integrated in OS X, so we need to install it. When you use the OS X system search function (Control+space) to try to find X11, will be prompted to install X11, choose to continue, will be taken to the online store, download xquartz-2.7.7.dmg This file, download complete installation. I'm using OS X Yosemite 10.10, going to ssh RedHat Linux, and these are all done under these prerequisites.ġ. Use a terminal under OS X, such as Iterm,ssh to a Linux machine, and then use Gnuplot on a Linux machine to draw.
