 Using the command "sudo fail2ban-client status sshd", from the output, get the banned ip addresses and sort them into the file "banned_ips.txt" displaying 1 ip address per line.
 </code>
+Answer from chatgtp needs some work:
+<code>
+#!/bin/bash
+# Get the banned IP addresses using the fail2ban-client command
+banned_ips=$(sudo fail2ban-client status sshd | grep "Banned IP list" | awk '{print $NF}')
+# Sort the banned IP addresses and store them in a file
+echo "$banned_ips" | sort | uniq > banned_ips.txt
+</code>
+This however only shows last ip address
+==== Patch Red Hat and Debian based systems and perform reboot if required using an ansible playbook ====
+<code>
+---
+- name: Patch both Debian and Red Hat based systems
+  hosts: all
+  become: yes
+  tasks:
+    - name: Update package index
+      apt: update_cache=yes
+      when: ansible_os_family == "Debian"
+    - name: Update package index
+      yum:
+        name: "*"
+        state: latest
+      when: ansible_os_family == "RedHat"
+    - name: Install patches
+      apt: upgrade=dist
+      when: ansible_os_family == "Debian"
+    - name: Install patches
+      yum: name=* state=latest
+      when: ansible_os_family == "RedHat"
+    - name: Check if a reboot is required
+      shell: "ls /var/run/reboot-required"
+      register: reboot_required
+      changed_when: false
+    - name: Perform reboot
+      reboot:
+      when: reboot_required.rc == 0
+</code>
+In this playbook, the apt module is used to update the package index and install patches on Debian-based systems, while the yum module is used for the same on Red Hat-based systems. The when statement is used to conditionally execute the correct module based on the value of ansible_os_family.
+After the patches have been installed, the playbook checks if a reboot is required by running the ls /var/run/reboot-required command. If the command returns a zero exit code, indicating that a reboot is required, the reboot module is used to perform the reboot.
