fail2ban whitelisting an IP address

From a terminal:

sudo ls -l /etc/fail2ban/jail.conf

sudo nano jail.conf

Add the IP address to whitelist to the ignoreip = <your_ip_address>

sudo systemctl restart fail2ban

Sep 7, 2022

fail2ban unban command

fail2ban-client -i

then in interactive mode type read the status of a jail:

status sshd

you'll get:

Status for the jail: ssh
|- Filter
|  |- Currently failed: 0
|  |- Total failed: 3
|  `- File list:    /var/log/auth.log
`- Actions
   |- Currently banned: 1
   |- Total banned: 2
   `- Banned IP list:   192.168.0.100

then type in fail2ban interactive mode:

set sshd unbanip 192.168.0.100

you'll get:

192.168.0.100

it means no longer 192.168.0.100 in ban list.

Journal article based off of 9,570 people tested to see if replacing a diet of Saturated Fat with Vegetable Oil rich in Linoleic Acid would reduce coronary heart disease and death. It decreased cholesterol but increased death--authors conclusion: this was due to the negative oxidative effects on lipoprotein from the consumption of Vegetable Oil.

Journal article discussing the Sugar industry's demonization of fat during the 1950's. The industry singled out fat and cholesterol as the dietary causes of CHD and downplayed evidence that sucrose consumption was also a risk factor. This alone caused decades of issues for American dietary education.

Apply
System > Alerts > Click Enabled for Enable Platform Event Filter Alerts
Apply
System > Alerts > Email Alert Settings > Enter destination email and Email Description
System > Alerts > Email Alert Settings > Enter in either your internal email server or external email relay. iDRAC 6 does work with external email relays outside of your organization.
Apply
System > Alerts > Email Alert Settings > Click Send to Test E-Mail

A successful email will be sent:

Subject: Alert from iDRAC

Message: [DELL IDRAC WARNING]
Message: TEST PAGE
Event: Email paging test to user.

Fixed: Jira server.xml special characters error

Issue:
When starting up Jira, an error is displayed blocking the startup. The error says server.xml has an issue with special characters then directs the admin to go https://confluence.atlassian.com/jirakb/changing-server-xml-to-handle-requests-with-special-characters-958453799.html.

Server setup:

Self-signed certificate for https
Https Port 8443

Here is the server.xml file that worked for me. I inserted at all Connector lines: relaxedPathChars="[]|" relaxedQueryChars="[]|{}^\`"<>"

How to: Installing Pi-hole on the Raspberry Pi w/CLI and SSH

This tutorial will build a Pi-hole server running on a Raspberry Pi 3. Pi-hole enables network-wide adblocking. Pi-hole is your own personal DNS Server and will not only protect your network from ads, but also from malicious websites, all the while improving page load performance. You will be able to access the Pi-hole via a web interface, and also manage the Raspberry Pi unit via SSH.

Hardware Required:

Raspberry Pi 3

4GB+ microSD card

Ethernet

Monitor connected via HDMI

Keyboard

Step 1: Getting the Raspberry Pi up and running

Download RASPBIAN STRETCH LITE https://www.raspberrypi.org/downloads/raspbian/

Unzip the image

Download Etcher https://github.com/balena-io/etcher/releases/download/v1.4.8/balenaEtcher-Setup-1.4.8-x64.exe

Flash the image to the microSD card (use a 4GB card or larger)

Connect keyboard and monitor and power to Raspberry Pi

Boot up

https://www.raspberrypi.org/documentation/linux/usage/users.md
Log in using

pi
passwd

Change password using: passwd

ifconfig
Write down the MAC address

If possible, assign the Raspberry Pi a static IP from within your router/firewall

Reset the Raspberry Pi so that the device gets assigned the new IP address from the router/firewall

ifconfig
confirm the IP is correct

Step 2: Installing Pi-hole

https://github.com/pi-hole/pi-hole/#one-step-automated-install

From Raspberry Pi's CLI, enter the following commands:
wget -O basic-install.sh https://install.pi-hole.net
sudo bash basic-install.sh

This will bring up the GUI to install Pi-hole. Use all of the default recommended settings.

Write down the password that is generated. This will be used to log into the web admin interface.

Step 3: Enabling SSH

https://www.raspberrypi.org/documentation/remote-access/ssh/

From Raspberry Pi's CLI:

Enter sudo raspi-config in a terminal window
Select Interfacing Options
Navigate to and select SSH
Choose Yes
Select Ok
Choose Finish
Alternatively, use systemctl to start the service

sudo systemctl enable ssh
sudo systemctl start ssh

Step 4: Configuring Pi-hole from web admin interface

Go to another computer/device connected to the same network

Open a browser

Visit the IP address of the Pi Hole device

Begin configuring Pi-hole.

Step 5: Set up Router's DNS settings to point to Pi-hole

Log into your Router

Change the DNS to point to the IP address of Pi-hole

Reboot all client machines to update their DNS server
