  • It’s finally working again. The new feature rustdesk privacy mode is really cool!

    This is most important for me to work on troubleshooting with PC Sticks. So I don’t want an expose password that i type. This is great.

    I’ve also set up three more rust desk relay servers on my machine so we can connect without any issues between Washington State and Arionza.

    We commenced utilizing rustdesk in August 2023, and their updates have been impeccable. We desire the service we receive, and I am grateful for their dedication to their work. I recommend that you consider purchasing a professional license if you wish to construct your own server.

  • DNS amplification attack | closing the 53 port on my AdGuard Home Server.

    Today, I turned off the DNS port 53. Since we have been cutting off our store’s DNS server, it has been a DNS amplification attack. So I found out that my Router does have a DNS Proxy, My DNS Server does have HTTP over TLS and DNS-over-HTTPS. Everything is working and attacking is currently stopped after I set up 853 port encryptions and disable Plain DNS. I also want to keep my stores safe.

    Disable Plain DNS and DNS over TLS is 853.

    My router has a DNS Proxy option, so I added my DNS IP Server,

    Then I have gone to Wired Networks → LAN, then go to Admin

    If you change DNS Server to your DNS, please change to Auto So DNS Proxy to do the job.

    Now we have an encrypted DNS over TLS.

  • How to set up MariaDB with Portainer Stacks +(Docker-compose)

    We’re using MariaDB for our business because it’s meant for big business, and it’s my favorite database to use for small businesses. And I have a lot of skill experience with MariaDB than any other database, but few other databases are lacking in my experience. Therefore, I do not have sufficient time to undertake these experiences. After I document all my notes and work for sure, I will study these (MongoDB, PostgreSQL) I use some on app after I document all my notes and work for sure. I will study these after I document all my notes and work for sure. Which is a pain for me, but I got the app working and stable. So let get start to Tutorial for MariaDB.

    Please ensure that you complete this first. Before starting build this,

    How to set up Portainer with nginx Proxy Manager

    We need to create a network for the MariaDB database for another app to communicate. We prefer to refrain from exposing our port.

    docker network create mariadb

    Now we can begin to create details for the MariaDB Database on Portainer.

     version: '2'
    services:
      mariadb:
        container_name: mariadb
        networks:
          - mariadb
        image: mariadb
        command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
        restart: always
        environment:
          - MYSQL_ROOT_PASSWORD=yourownpassword
          - MARIADB_AUTO_UPGRADE=1
          - MARIADB_DISABLE_UPGRADE_BACKUP=1
        volumes:
          - /mnt/nasdrive/mariadb/:/var/lib/mysql
    networks:
      mariadb:
        external: true

    Then you deploy the stacks. Your app will then be operational. Thereafter, you can easily add PhpMyAdmin to this docker-compose. But I like stacks because we can use the same app for many server databases.

    OPTIONAL BONUS for PhpMyAdmin How to set up.

  • How to set up PhpMyAdmin with MariaDB on Portainer with NGINX Proxy Manger.

    PhpMyAdmin is easy to set up for any app and fix the table database or troubleshoot. So, we will set up PhpMyAdmin with NGINX SSL secure for our HTTPS. Due to the possibility of a grabber username and password exploit, we would prefer not to expose this on HTTP.

    Please ensure that you complete this first. Before starting, we should make sure that this tutorial prevents hacking and exposes our port to the public. We do not want that to happen. We only want 80 and 443 to be open.

    How to set up Portainer with nginx Proxy Manager

    After you complete Portainer and nginx, we are good to go to build this app with nginx and PhpMyAdmin.

    Open Portainer → Stacks→ create stacks

    version: '3'
    services:
      pma:
        networks:
          - nginx
          - mariadb
        image: phpmyadmin/phpmyadmin
        container_name: pma
        environment:
          PMA_ARBITRARY: 1
        restart: always
        #ports:
         # - 8081:80
    networks:
      nginx:
        external: true
      mariadb:
        external: true

    I put hashtags on ports and port numbers because we don’t need them. We’ll just use nginx network on this app. Nginx proxy can talk to PhpMyAdmin instead of port or public. It is more secure to build our app before it is published to the public. Your sites can be injected with any insecure port.

    After deploying the stacks, your PhpMyAdmin is now online, but it won’t show up on the site because you didn’t set up the nginx proxy info. That would be our next step.

    You should open the nginx proxy manager for your site. My will be nginx__.richardapplegate.io.

    Thereafter, you’ll need to access your admin account. Add proxy host, then fill this detail.

    I configured the PMA to forward hostname/IP as a result of setting docker-compose on the PhpMyAdmin container_name to the PMA. And this app uses 80 ports on the NGINX network.
    Make sure you enable SSL and HTTP/2 and HSTS.

    Now you may be able to open your site with a domain without port. My will be phpmyadmin.richardapplegate.io. and working!

    Server: your database container_name on docker-compose. Mine is mariadatabase
    Username: your primary account for all database control. Mine is root.
    Password: you create the password and the password should on your docker-compose. You won’t be possible to log in my PhpMyAdmin because 3 times incorrect information, then you will be banned. You won’t access from my server or see my sites anymore for 1 week.

    You’re in the MariaDB database.

    “SSL is not being used” is normal because itself PhpMyAdmin is not on public, it is on nginx proxy manager. So, PhpMyAdmin is not public, it is full secured under the nginx. And you can see that we can create databases or tables or control user accounts.
  • How to set up Baserow on Portainer with nginx proxy manager

    This baserow is my absolute favorite, it’s more like a spreadsheet with more options and an easy-to-use database. It also had a Grid and Form and a Gallery and a Calendar! It’s great for our list of things to do.

    Look over Baserow.io!

    You’ll need Portainer and nginx running, remember? If not, here are my instruction to set up on your server.

    Let’s build stacks now.

    Open Portainer site → stacks → add stacks

    version: "3.4"
    services:
      baserow:
        container_name: applegate-baserow
        image: baserow/baserow:1.24.2
        networks:
          - nginx
          - mariadb
        environment:
          BASEROW_PUBLIC_URL: 'https://sub.domain.com'
        volumes:
          - /yourpath/baserow/data:/baserow/data
    networks:
      nginx:
        external: true
      mariadb:
        external: true
        

    Before you deploy, please ensure you follow the high light and modify and edit the networks to match your nginx proxy manager and MariaDB Database Network. Then, deploy the stack and this app is online but not show on site. We need to go to nginx proxy manager to set up a proxy host for baserow.

    Scheme – HTTP
    Forward Hostname – Your container_name here
    Forward port – Expose 80 to here.
    ensure to enable SSL and HTTP/2 and HSTS

    The sign-up form should appear when you open the base row. Please complete it for the first user, and this account will provide you with an admin account.

  • How to set up agent edge on multiserver

    Docker-compose is my go-to for secondary or distributed servers. It’s better than docker run because it’s more clean and organized and easier to set up. And one time, too.

    So all you need to do is make sure the Secondary Server or Multiserver needs to install Docker and Docker Compose. Please follow this step by step.

    Install Docker Engine on Ubuntu | Docker Documentation

    Now that we have created the docker-compose files, we can create them where you want them to be saved. The secondary server has not yet set up Portainer, so this tutorial is for using SSH instead of Portainer. The docker compose will do the job, and our primary server will attach secondary from an outside server. This is cool, no need to use a port or anything else.

    Open the Portainer site on the primary server, then go to environment, add environment, Docker standalone, start wizard, and edge agent standard. Write down your edge ID and key in this way.

    You should see Edge ID and Edge Key on the primary Portainer site.

    Please ensure that you obtain the Edge ID and Edge Key. Make sure to change your volume path and change your volume path. Look for the highlights below.

    Version: '3.9'
    services:
        agent:
            image: 'portainer/agent:2.20.2'
            container_name: portainer_edge_agent
            environment:
                - EDGE_INSECURE_POLL=1
                - EDGE_KEY=
                - EDGE_ID=
                - EDGE=1
            restart: always
            volumes:
                - '/yourpathportainer/data:/data'
                - '/:/host'
                - '/var/lib/docker/volumes:/var/lib/docker/volumes'
                - '/var/run/docker.sock:/var/run/docker.sock'
    

    After deploying the stack, your secondary portainer should be active and should appear on your primary portainer. Look like this:

    Continue to deploy and build Docker Portainer many more servers to benefit the future!

  • Fail2ban – how to unbanip on your sshd

    IP address unban

    Fail2Ban is an intrusion prevention system that protects computer servers from brute-force attacks. It can monitor specific logs and block IP addresses that act like brute-force attacks.

    Fail2Ban particularly monitors the number of connection attempts. After 5 failed SSH connection attempts, Fail2Ban will ban the IP address from connecting via SSH for 10 minutes. If this address fails several times, it might be banned permanently until you contact admin@richardapplegate.io and explain why you are attacking my server.

    Unban an IP address

    To unblock an IP address, you must first access it from another IP (VPN) address or internet connection than the one that is blocked.

    Look at the Fail2Ban log to find out where the IP address was banned.jail

    sudo tail /var/log/fail2ban.log 
    2019-01-07 16:24:47 fail2ban.filter  [1837]: INFO    [sshd] Found 11.22.33.44 
    2019-01-07 16:24:49 fail2ban.filter  [1837]: INFO    [sshd] Found 11.22.33.44 
    2019-01-07 16:24:51 fail2ban.filter  [1837]: INFO    [sshd] Found 11.22.33.44 
    2019-01-07 16:24:54 fail2ban.filter  [1837]: INFO    [sshd] Found 11.22.33.44 
    2019-01-07 16:24:57 fail2ban.filter  [1837]: INFO    [sshd] Found 11.22.33.44 
    2019-01-07 16:24:57 fail2ban.actions [1837]: NOTICE  [sshd] Ban 11.22.33.44 
    2019-01-07 16:24:57 fail2ban.filter  [1837]: NOTICE  [recidive] Ban 11.22.33.44

    Here, the 11.22.33.44 IP address has been banned in the sshd and recidive jails.

    Then use the following commands to unban the IP address.

    sudo fail2ban-client set sshd unbanip 11.22.33.44
    sudo fail2ban-client set recidive unbanip 11.22.33.44
  • Backup and Restore with Docker Compose

    All of my data is on folder drive mounts that where our data is to make backup and restore operations easier. Stopping your stack with docker-compose down will allow you to back up all the files and subfolders in the folder next to the docker-compose.yml file.

    For example, if you want to create a ZIP archive, you can use the following command:

    zip -r myarchive.zip .
    

    To restore from a ZIP archive, please unzip the archive into the original folder using the following command.

    unzip myarchive.zip -d /path/to/original/folder
    

    Once your backup has been completed, you can start your stack again with the following command:

    docker-compose up -d
    

    This is all. With these simple steps, you can easily backup and restore your data volumes with Docker Compose.
