Ssh -Y -J is now an X11 capable command-line session on .edu connecting through the bastion host. To log on to the .edu front-end from on-campus and allow X11 forwarding, the command is: Once this is done and XQuartzshould start automatically once an X program is launched from your terminal. To use graphics on MacOS from the HPC cluster, you will not only need to pass -Y, but you also need to install XQuartz on your Mac so the terminal has the ability to forward graphics from HPC to your Mac: Connecting directly to HPC clusters from off-campus via Linux through the IT bastion host with X11 forwarding: Ssh -J is now a command-line on .edu that connected through the bastion host. Once this is complete, you will then need to enter your W&M password again to log into .edu. If you do not have an ssh key added to the bastion host (see for more information), you will need to authenticate via DUO after entering your W&M password. Logs of this container contain the same problem: libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast. To ssh through the IT bastion host to a HPC cluster front-end server, you must simply add -J the previous ssh command: I have downgraded Xquartz to version 2.7.8 but my app opens like black window and instantly closes. Connecting directly to HPC clusters from off-campus via Mac through the IT bastion host: This is now an X11 capable command-line session on .edu. Ssh -Y is an example with the -Y passed along, note that the session is able to launch the program xterm from bora which opens a new terminal on my local computer (the white window): Once this is done and XQuartz should start automatically once an X program is launched from your terminal. To use graphics on MacOS from the HPC cluster, you will not only need to pass -Y, but you also need to install XQuartz on your Mac so the terminal has the ability to forward graphics from HPC to your Mac. Connecting directly to HPC clusters from on-campus (main or VIMS) via Mac with X11 forwarding: This is now a command-line session on .edu. Here is an example with = ejwalt making an ssh connection to the HPC front-end with = .edu : For almost all HPC users, your is your W&M username. It will be explicitly included in all examples. Ssh that can be omitted if it matches your local computer username. Using ssh to connect to an HPC cluster front-end consists of one command: On a Mac, ssh commands within the terminal program can be used to connect to main- or VIMS campus HPC front-end hosts (such as .edu or ). Off-campus via Linux through the IT bastion host via Mac w/ X11 forwarding using XQuartzĬonnecting directly to HPC clusters from on-campus (main or VIMS) via Mac.Off-campus via Linux through the IT bastion host via Mac Once MacPorts is installed, we need to now install something called XQuartz.On-campus (main or VIMS) via Mac w/ X11 forwarding using XQuartz.
