diditho — Wed, 04 Nov 2026 11:40:26 +0000

Running an older database version in production is not necessarily a problem, especially when it is stable and has been running reliably for years. However, there comes a point when security updates, performance improvements, and new features make upgrading a reasonable decision. Recently, I needed to plan an upgrade of a MariaDB environment running on... Continue reading →

MariaDB 11.8 Upgrade on Debian 12, Fixing Missing Compression Provider Plugins

diditho — Wed, 04 Nov 2026 06:52:12 +0000

Upgrading a database server is usually straightforward when everything goes according to plan. Update the repository, install the new packages, restart the service, and verify that the database is running. But sometimes, a successful package installation is only half the story. Recently, I upgraded a MariaDB Master–Slave replication environment from MariaDB 10.11.19 to 11.8.9 on... Continue reading →

Upgrade Node.js 20 to Node.js 24 on Debian 12 Using APT: A Security-Focused Guide

diditho — Sat, 24 Oct 2026 01:07:34 +0000

Node.js is a critical component of many production environments, powering REST APIs, background workers, web applications, and real-time services. Keeping the runtime updated is an important part of maintaining server security. On April 30, 2026, Node.js 20 reached End of Life (EOL). This means it no longer receives official upstream security updates. The October 21,... Continue reading →

Ada Suara yang Tidak Semua Orang Bisa Dengarkan

Beberapa hari lalu, ritme kerja kami terhenti sejenak karena tim mendapat kabar bila salah satu agency rekanan kami akan libur pada hari Jumat dan Senin. Kita harus mengatur ulang deliverables salah satu project client. Menariknya adalah alasan libur tersebut, karena setahu kami tidak ada libur nasional di tanggal 9 dan 12 Oktober 2026. Wow, keren...

How to Stop MongoDB 8.x.x Log Files from Exploding on Debian 12/13

diditho — Thu, 16 Apr 2026 05:45:11 +0000

MongoDB 8.x.x is one of those services that can run quietly for a long time, until one day you check disk usage and realize the log file has grown into something unreasonable. Not because MongoDB 8.x.x is broken, but because the logging behavior is doing exactly what it was told to do, keep writing, keep... Continue reading →

How to Upgrade Wazuh on Ubuntu 24.04 and Fix a wazuh-manager Timeout During the Process

diditho — Tue, 31 Mar 2026 07:59:50 +0000

Upgrading Wazuh on Ubuntu 24.04 can look successful at first, only to stall at the final step when wazuh-manager fails to complete its post-install process. In this guide, I walk through a real upgrade from Wazuh 4.13.1 to 4.14.4, explain why the dashboard may still load while the API remains unavailable, and show how a simple systemd override can allow the manager to start cleanly and complete the upgrade.

How to Sync Only MariaDB Users and Passwords from Master to Slave

diditho — Mon, 16 Mar 2026 06:03:43 +0000

Sometimes I want a MariaDB slave to have the same user accounts and passwords as the master, but I do not want it to inherit the same permissions. This is common when the slave is used for reporting, internal access, standby, or a limited failover role. The accounts may need to match, but the grants... Continue reading →

Moving a MariaDB Database Between Servers (The Simple Way)

diditho — Fri, 13 Mar 2026 03:20:48 +0000

Sometimes the hardest problems in infrastructure are actually the simplest ones. Not because they are complicated, but because we forget the exact commands when we need them. Migrating a MariaDB database from one server to another is one of those things. You’ve done it many times, but when you need it again six months later,... Continue reading →

Docker SFTP Port Works on localhost but Times Out from Outside (Debian 12 + ferm + Linode NAT)

diditho — Tue, 03 Mar 2026 07:37:49 +0000

I hit a classic “it must be Docker” moment. This post documents what was actually happening and the minimal, correct fix. The setup Symptom, “Local open, remote timeout” On the server: Everything looked correct: Docker was listening on 0.0.0.0:22222, and localhost could connect. But from outside, connections to port 22222 timed out. First principle, don’t... Continue reading →

Reseeding MariaDB Master–Slave Replication (Non-GTID) While the Master Stays Online

diditho — Thu, 12 Feb 2026 12:13:54 +0000

MariaDB replication breaks at the worst possible time, right when you need the database to be calm, predictable, and boring. If you’re running classic (non-GTID) master–slave replication, the fastest way out of a messy drift is usually not to “skip errors” or “restart services” endlessly. The cleanest recovery is to reseed the slave from a... Continue reading →
