{{Admon/important|Access Changed Jan 16March 17, 2015|Access to the host "Red" was changed on January 16March 17, 2015 -- the gateway host ''Red'' is now ''Moroccodirectly accessible at <code>red.proximity.on.ca'' </code> instead of ''Iraq.proximity.on.ca''going through a gateway host. You will need to change your <code>~/.ssh/config</code> file if you set it up before that date.}}
In [[SPO600]], remote access to two servers is provided for learning and project work. It is recommended that you also set up [[SPO600 Host Setup|a personal Fedora system]].
== 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 as <code>Moroccored.proximity.on.ca</code> (note that Morocco is just the gateway - your connection will be forwarded automatically to Red). - To connect from a command-line ssh client: ssh -p 2222 ''username''@morocco.proximity.on.ca If you are using the OpenSSH client, you can simplify this process by creating an entry in your <code>~/.ssh/config</code> file: Host "red" hostname "morocco.proximity.on.ca" port 2222 You can then simply:
ssh ''username''@red.proximity.on.ca
{{Admon/note|Why Red?|When the first three servers arrived for the [[EHL]], we named them Red, Green, and Blue, after the colours of the ethernet cables we had - so that we could tell them apart easily. In the EHL cabinet, they're labelled x1 (Blue), x2 (Red), and x3 (Green), along with the other 1u ARM64 servers.}}
