How the CS 1.6 MOTD window loads motd.txt, the size limit that truncates it, the URL mode, and how to write HTML that renders in the in-game browser.

sys_ticrate, -pingboost and the CPU are the three things that decide whether your server holds a high tick rate. Here is how they fit together on Linux, and why ReHLDS is the real fix.

The internet server list is empty. The cause is usually an outdated master-server list, a blocked UDP query port, or a client that is too new. Here is how to get servers back.

Read and write entity variables with pev/set_pev, call engine and DLL functions, and hook engine forwards like FM_PlayerPreThink and FM_EmitSound.

Compile ReHLDS yourself in a reproducible Docker container instead of trusting a random binary, and verify the engine you built is the one your server loads.

The connect handshake behind 'Connection failed after 4 retries' - UDP reachability, sv_lan, rate/netchan limits, wrong port, and provider-level UDP filtering - each with a concrete test.

Choke and loss look similar but have opposite causes: choke is your server hitting a rate cap, loss is real packet loss. How to tell them apart with net_graph and fix each.

Install YaPB, the actively maintained CS 1.6 bot, as a Metamod plugin, get the navigation graph loaded, and control bot count with yb_quota.

The correct way to install an AMX Mod X plugin: where the .amxx goes, registering it in plugins.ini, config and module dependencies, and why plugins silently fail to load.

Work through every reason AMX Mod X reports a module as failed to load: wrong architecture, missing system libraries, version mismatch, and modules.ini configuration.

Swap Valve's swds.dll for ReHLDS on a Windows CS 1.6 server, verify the engine actually loaded, and avoid the DLL and antivirus traps.

A worked estimate of the outbound and inbound bandwidth a full CS 1.6 server consumes, how rates and updaterate drive it, and how to turn Mbps into a monthly total.
