• 18:44, 6 March 2026 Mcnabb talk contribs created page Ssh alias and ssh-keygen (Created page with "CAS servers support connections using ssh. You may find the following using to use ssh-keygen and ssh alias. === Linux: === Create a public/private key pair with ssh-keygen. ssh-keygen -t ed25519 -C "your_email@example.com" Depending on your use case, you may or may not want to enter a passphrase. If you do use a passphrase it should not be the same as your password for our servers! This should create two files: ~/.ssh/id_ed25519        # private key (keep secr...") Tag: Visual edit

To properly set up virtual environments so that they will work on both the servers and the cluster compute nodes, all files need to be in your /data/common/${USER} directory, not your home directory. Symbolic links in /data/common will not suffice, however symbolic links to these di...") Tag: Visual edit

The GNU Compiling Collection (GCC) is available for compiling C, C++, and Fortran code. Individuals wishing to use python are advised to use individual virtual environments, instead of the system wide install of python, for running existing python based codes or for their software development.

You go to https://jupyter.cas.hamptonu.edu/ On the left hand side are the files in your home directory.  On the right will be a launcher.  If you open the terminal it will allow you to do commands, although it does not allow xwindows to be used, so no GUIs.  You can open ipynb files which will should work, but may need a kernel other then the default pytho...")
