Linux Firewall Basics: ufw vs firewalld (Quick Start)

<p><img alt="Linux ufw firewall status showing allowed SSH and web ports" src="https://blog.gnomeitsolutions.com/wp-content/uploads/2026/08/blogger-firewall-ufw.png" style="max-width:100%;height:auto;border-radius:6px;"/></p><p>Every Linux server needs a firewall. On Debian/Ubuntu you usually see <strong>ufw</strong>; on RHEL/CentOS/Rocky it's <strong>firewalld</strong>. Both wrap iptables/nftables—pick one and stay consistent.</p><h2>ufw (Ubuntu / Debian)</h2><pre><code>sudo ufw default deny incoming

sudo ufw allow 80,443/tcp comment 'Web'

sudo firewall-cmd --reload
sudo firewall-cmd --list-all</code></pre><h2>Before you lock yourself out</h2><ul><li>Keep an active SSH session open while testing rules</li><li>Allow SSH <em>before</em> enabling the firewall</li><li>Use a cloud console (VNC/serial) as backup access</li></ul>

Detect SSH Brute-Force Attacks on Linux (auth.log + fail2ban)

<p><img alt="fail2ban SSH jail status on Linux server terminal" src="https://blog.gnomeitsolutions.com/wp-content/uploads/2026/08/blogger-ssh-fail2ban-2.png" style="max-width:100%;height:auto;border-radius:6px;"/></p><p>SSH is the front door to most Linux servers. Attackers scan the internet 24/7 looking for weak passwords and open port 22. This guide shows how to spot brute-force attempts quickly and block repeat offenders with <strong>fail2ban</strong>.</p><h2>1. Check auth.log for failed logins</h2><pre><code>sudo grep 'Failed password' /var/log/auth.log | tail -20
sudo grep 'Invalid user' /var/log/auth.log | awk '{print $10}' | sort | uniq -c | sort -rn | head</code></pre><p>The second command lists usernames attackers tried most often (root, admin, ubuntu, etc.).</p><h2>2. Count attempts by source IP</h2><pre><code>sudo grep 'Failed password' /var/log/auth.log \
  | awk '{print $(NF-3)}' | sort | uniq -c | sort -rn | head -15</code></pre><p>Any IP with hundreds of failures in a short window is almost certainly a bot.</p><h2>3. Install and enable fail2ban</h2><pre><code>sudo apt update && sudo apt install -y fail2ban
sudo systemctl enable --now fail2ban
sudo fail2ban-client status sshd</code></pre><h2>4. Harden sshd (do this first)</h2><ul><li>Disable password login: <code>PasswordAuthentication no</code></li><li>Disable root login: <code>PermitRootLogin no</code></li><li>Use a non-default port or restrict with firewall</li><li>Allow only your admin IP if possible</li></ul><p>After editing <code>/etc/ssh/sshd_config</code>, run <code>sudo sshd -t && sudo systemctl reload sshd</code>.</p><h2>5. Monitor bans</h2><pre><code>sudo fail2ban-client status sshd
sudo zgrep 'Ban' /var/log/fail2ban.log | tail -10</code></pre><p>Review banned IPs weekly. Legitimate users behind NAT can trigger bans if they mistype passwords—adjust <code>maxretry</code> and <code>bantime</code> in <code>/etc/fail2ban/jail.local</code>.</p>

How to Install Jitsi Meet on Ubuntu 22.04

The Jitsi project began with the Jitsi Desktop (previously known as SIP Communicator). With the growth of WebRTC, the project team focus shifted to the Jitsi Videobridge for allowing web-based multi-party video calling. Later the team added Jitsi Meet, a full video conferencing application that includes web, Android, and iOS clients. Jitsi also operates meet.jit.si, a version of Jitsi Meet hosted by Jitsi for free community use.

<p style="text-align: center;"><span style="color: #2b00fe; font-family: verdana; font-size: large;"><b><u>How To Install MySQL Server on Ubuntu 22.04</u></b></span></p><p><span style="font-family: verdana; font-size: large;">MySQL is an open-source relational database management system (RDBMS).Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqb_IjkqiXKg6rDmYejq7XSHARNEO7FQeNRUS_wOIn21jrjNbbAU7E6G9eRLRdYqi_Rde4_MExFxTI7vEQLKUepAv77VJY1ZcxLbpmQ-UaCqNfiVGecOeUXAnJxJOQqO-mHBETDm6S0oRb/s698/mysql-hackthesec.png" style="margin-left: 1em; margin-right: 1em;"><span style="font-size: large;"><img border="0" data-original-height="400" data-original-width="698" height="366" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqb_IjkqiXKg6rDmYejq7XSHARNEO7FQeNRUS_wOIn21jrjNbbAU7E6G9eRLRdYqi_Rde4_MExFxTI7vEQLKUepAv77VJY1ZcxLbpmQ-UaCqNfiVGecOeUXAnJxJOQqO-mHBETDm6S0oRb/w640-h366/mysql-hackthesec.png" width="640" /></span></a></div><span style="font-size: large;"><br /><span style="font-family: verdana;"><br /></span></span><p></p><p><span style="color: #2b00fe; font-family: verdana; font-size: large;"><b>Step 1 – Installing MySQL on Ubuntu 22.04</b></span></p><p><span style="font-family: verdana; font-size: large;">The default Ubuntu repositories contain MySQL 8.0.
