+= Automation using Python and Paramiko =
+If you are using the [https://www.paramiko.org/index.html Paramiko Python module] to automate your workflow, this is how you can make it work with the robot nodes:
+<source lang=python>
+# ====================================================================================================
+#! /usr/bin/env python3
+# ====================================================================================================
+import os
+import paramiko
+# ====================================================================================================
+key = paramiko.Ed25519Key.from_private_key_file("/home/username/.ssh/cc_allowed")
+user = "username"
+host = "robot.graham.alliancecan.ca"
+ssh = paramiko.SSHClient()
+# If the host is not known, it is OK.
+ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
+ssh.connect(hostname=host, username=user, pkey=key)
+cmd = "ls -l"
+stdin, stdout, stderr = ssh.exec_command(cmd)
+print("".join(stdout.readlines()))
+ssh.close()
+# ====================================================================================================
+</source>
+This code connects to the robot node on '''Graham''' using an automation key specified in CCDB and
+executes the <code>ls -l</code> command to get the list of files.
+Then prints the list to the screen.
+Note, that it is important to install '''paramiko''' with the
+ $ pip install paramiko[all]
+command. This will make sure that the support for the '''Ed25519''' key type will also be installed.
