+===== Portal SSH Login Cluster =====
+**__Portal is NOT a website__**
+The ''%%portal%%'' cluster is a general purpose cluster of servers which is the gateway into the CS Dept. computing environment. Logins are load balanced among the servers. Upon an 'ssh' to ''%%portal.cs.virginia.edu%%'', your login will be placed on the least loaded of the cluster's servers (portal[01,02, etc.]). Each system is running **Ubuntu Linux** and has plenty of memory, CPU cores, and scratch space. Your home directory is automatically mounted and available when you login.
+----
+===== Logging in with SSH =====
+Replace ''%%<userid>%%'' with your CS userid (which is identical to your UVA Computing ID), and provide your password to 'ssh' into portal.
+Temporary passwords are sent via email when your CS account is created initially. After logging in for the first time, you will be required to change your password
+<code>
+~$ ssh <userid>@portal.cs.virginia.edu
+</code>
+Note, for the first time you connect via SSH, you will see the following output
+<code>
+Are you sure you want to continue connecting (yes/no)?
+</code>
+Enter **yes** to continue
+Note, that if you are opening a terminal on your Mac or PC, your username on the Mac or PC may be different from your CS domain userid. So be sure to include your CS/UVA userid on the 'ssh' command line.
+==== SSH for Linux & MacOS ====
+Application for running this command are **Terminal**
+==== SSH for Windows ====
+Applications for running this commands are **Command Prompt** or **PowerShell**
+For further reading see: ([[linux_ssh_access|SSH Logins]])

+===== Additional Information =====
+Most popular software is already available on portal, so you do not need to install it. See: [[software_modules|Software Modules]]
+You can use portal to perform many interactive tasks, like editing files, compiling code, testing code, etc. If you intend to run long, compute intensive programs, you should use other [[compute_resources|Computing Resources]] which are available for general login or through the job scheduler (see [[compute_slurm|Scheduling a Job using the SLURM job scheduler]]).
+See [[linux_ssh_access|Linux Server Access]] for more information about accessing CS Dept servers.
