Hi, Admin command, scans a specified range around the admin. It gathers about players within the specified range, including their clan names, party leaders, and class names. Counting all players around can be a helpful task for admins. You could limit the scanning to players within the same region or zone as the admin - this would reduce the number of players to be processed and improve performance.

The client side only changes the information and skill category. What you need to change on the server side is the target, skill type, operation type and effect to be Damage Over Time instead of Buff.

I didn't read the whole code: final Player tmp = _player.getClient().getPlayer(); final Party party = tmp.getParty();

Kindly delete this code permanently. I'm not kidding.

You need the client side as well.

It's necessary for you to indicate the pack and the type of client protection you're using. By default, I don't believe the client is capable of supporting that.

Moved to client section.

You don't need: final Player tmp = getClient().getPlayer(); Change: final Party party = tmp.getParty(); To: final Party party = _player.getParty();

Why would you even want to do that?

I have refreshed the GitHub repositories referenced in the main topic to enhance the coherence between the guides.

I've added Webmin Installation Guide - a web-based system administration tool.

Not related to Lineage 2.

Cool.

Thanks for pointing out that I forgot to add the installation of conntrack in my GitHub repository, as it is already integrated into this repository. To install conntrack, you can use the following command: sudo apt-get install conntrack -y it's possible that your system has some restrictions on the maximum allowed values for net.ipv4.tcp_rmem and net.ipv4.tcp_wmem, try to lower the values. It's basically min, default, max - receive buffer space for TCP connections. Which configuration did you try to apply? P.S. I've updated the GitHub repo.

It's time to focus on the most popular Linux distro. I've shared the following repositories on GitHub: Installing IPTables, Ipset, Conntrack and netfilter-persistent on Ubuntu Server 22.04 This guide will walk you through the process of installing IPTables, Ipset, Conntrack and netfilter-persistent on Ubuntu Server 22.04. netfilter-persistent: allow you to save and load your IPSET and IPTABLES rules automatically on boot. This ensures that your firewall settings are always loaded, even after a reboot. Optimizing Ubuntu 22.04 for Low Latency and High Performance This guide will walk you through the steps for optimizing your Ubuntu 22.04 system for low latency and high performance. The optimizations aim to improve the performance of a Linux-based system by modifying various network settings. Some of the changes include increasing the maximum number of open file descriptors, increasing the maximum number of processes, enabling TCP time-wait reuse, adjusting TCP keepalive time, setting the local port range for TCP connections, and increasing the maximum number of allowed concurrent network connections. Additionally, the values for the system's network buffer sizes are also increased to improve network performance. The optimizations aim to improve the system's overall stability and responsiveness in handling high network traffic. MariaDB installation and optimization on Ubuntu This guide explains how to install and optimize MariaDB on Ubuntu Checking if the script is run as root Checking if the script has been run before Updating package lists and upgrading packages Installing MariaDB if it's not already installed Prompting the user to select an optimization level (either to use up to 50% of total RAM and CPU, or up to 100% if MariaDB is the sole service on the server) Backing up the original MariaDB configuration file Calculating hardware-based settings (based on total memory and CPU cores) Configuring MariaDB performance settings based on the chosen optimization level and hardware Restarting the MariaDB service if the user agrees MariaDB Management Script for Ubuntu This shell script provides a simple way to manage MariaDB on Ubuntu 22.04 or newer. Creating, deleting, and flushing MariaDB users. Creating, deleting, and updating databases. Importing and exporting SQL files. Webmin Installation Guide for Ubuntu Server 22.04 Webmin is a web-based system administration tool for Unix/Linux systems that allows users to manage their system resources and services through a web interface. It provides a graphical user interface (GUI) for many common administrative tasks and simplifies the management of a Linux system for both novice and experienced users. System configuration: Webmin provides a GUI for configuring many aspects of your system, including network settings, user accounts, system services, and hardware settings. Package management: Webmin makes it easy to manage software packages on your system. You can view and install available packages, update installed packages, and configure package repositories. Server management: Webmin supports a variety of server applications, including Apache, MySQL, and PostgreSQL. You can configure server settings, manage virtual hosts and databases, and view server logs. File management: Webmin includes a file manager that allows you to browse and manage files on your system, including copying, moving, and deleting files. Monitoring: Webmin provides real-time monitoring of system resources such as CPU usage, memory usage, and disk space. You can also set up alerts to be notified when resource usage exceeds specified thresholds. Security: Webmin includes a variety of security features, including SSL/TLS encryption for web traffic, authentication and authorization for user accounts, and firewall configuration. Your feedback is welcome.

Is this classic client adapted to Interlude's protocol or what?

Use computeIfAbsent() to avoid creating empty effect maps for players with no effects. Use Entry in the forEach() loop instead of two parameters.

My reply is strictly referring to server side.
