== Available Servers == === AArch64: red ===
The first server is an [[ARMv8]] AArch64 system known simply as '''red'''. This machine is accessible via SSH using port 2222 on the host <code>Morocco.proximity.on.ca</code>. To connect from a command-line ssh client:
ssh ''username''@red
=== x86_64: australia ===
The other server is an x86_64 system known as <code>Australia.proximity.on.ca</code>. To connect to it, issue this command:
ssh ''username''@australia.proximity.on.ca
== Sudo Access ==
To perform operations which require ''privilege'', such as installing software, use the <code>sudo</code> command to execute the desired instruction as the <code>root</code> user.
For example, to install the software packaged <code>ncurses-devel</code>, execute: <code>sudo dnf install ncurses-devel</code> or <code>sudo yum install ncurses-devel</code>
{{Admon/caution|Danger! Use at your Own Risk|Note that the use of the superuser account via <code>sudo</code> removes almost all restrictions on what you can do. It is easily possible for you to completely destroy the operating system! Take your time, double-check your commands, and if in doubt, ask.}}
== Multiuser Access ==
Remember that these machines are multi-user systems. Use the <code>w</code> or <code>who</code> commands to see who else is using them; you can also try using the <code>write</code> command to communicate with another user if required.
