CS 1.6 server.cfg Explained: Key Commands and Examples

A practical CS 1.6 server.cfg guide covering file location, a copyable baseline, access and gameplay commands, mod caveats, reloading, and troubleshooting.

server.cfg is the plain-text file that applies your Counter-Strike 1.6 dedicated-server rules when HLDS starts. Put it at <HLDS install>/cstrike/server.cfg, save it as plain text, and use exec server.cfg (or authenticated rcon exec server.cfg) to apply edits without rebuilding the file.

The settings below cover server visibility, passwords, player limits, round pacing, economy, team rules, and basic integrity controls. They are a practical baseline rather than a universal competitive standard: installed server builds and gameplay plugins can change which values are accepted or override them later.

What server.cfg controls

HLDS reads server.cfg as a list of console commands. Each non-blank line sets a cvar or invokes a command. The file normally runs during server startup, so persistent rules belong there instead of being typed manually after every restart.

Use a basic text editor, not a word processor. Save the filename exactly as server.cfg; an accidental name such as server.cfg.txt will not be loaded. Keep comments after // when you want to document a choice, and put quoted text around names or passwords that contain spaces.

Where to put the file

For a standard dedicated installation, the path is:

<HLDS install>/cstrike/server.cfg

For example, if HLDS is installed in D:HLDS, the file is D:HLDScstrikeserver.cfg. Linux installations use the equivalent HLDS directory and forward slashes. If a host supplies a control panel, its file manager may open the same cstrike directory; verify that you are editing the live instance rather than a backup or a different game installation.

A copyable baseline configuration

This compact starting point gives an internet-facing, 20-slot server with conventional round and economy timings. Change the name, capacity, and rules to suit your group before deploying it.

hostname "My CS 1.6 Server"
sv_password ""          // blank keeps the server open; set a value for private play
sv_lan 0                 // internet server; use 1 for LAN
maxplayers 20

mp_timelimit 25
mp_roundtime 2.5
mp_freezetime 6
mp_startmoney 800
mp_buytime 0.25
mp_c4timer 35

mp_friendlyfire 0
mp_autoteambalance 1
mp_limitteams 2
sv_cheats 0
sv_consistency 1

The example values come from commonly used CS 1.6 templates and command documentation. Treat them as defaults to verify against your HLDS build, map cycle, and installed plugins. A mod can change a cvar after this file executes, so the value shown at runtime is the value that matters.

Identity, access, and capacity

These commands determine what players see in the browser and who can connect.

Command Function Typical use
hostname Sets the public server name shown to players. hostname "My CS 1.6 Server"
sv_password Requires a password to join. An empty value leaves the server open. sv_password "scrim123"
sv_lan Selects LAN-only mode when set to 1; 0 is used for an internet server. sv_lan 0
maxplayers Sets the player-slot ceiling for the process. maxplayers 20

Public server

Use a descriptive hostname, leave sv_password blank, and set sv_lan 0. Choose maxplayers conservatively: every additional slot increases CPU, memory, network, and administrative load, and a larger capacity does not improve a server that cannot maintain stable latency.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Private scrim or event

Set a non-empty sv_password and distribute it only to participants. Do not place an RCON password in a public article, screenshot, or shared configuration example. RCON credentials grant administrative control and should be stored separately from material intended for players.

LAN testing

Set sv_lan 1 while testing on a local network. Switch back to sv_lan 0 before an internet session; otherwise remote players may not be able to discover or join the server as expected.

Round pacing and the bomb timer

Five match cvars shape how long players prepare, buy equipment, and complete a round.

Command Unit Example Effect on play
mp_timelimit Minutes per map mp_timelimit 25 Ends or advances the map after the time limit.
mp_roundtime Minutes per round mp_roundtime 2.5 Controls the maximum pre-objective round duration.
mp_freezetime Seconds at round start mp_freezetime 6 Gives teams time to coordinate before movement begins.
mp_buytime Minutes for purchasing mp_buytime 0.25 Defines how long the buy period remains available.
mp_c4timer Seconds after bomb plant mp_c4timer 35 Sets the post-plant countdown.

Choosing values

A shorter mp_roundtime creates faster rotations and less time for late objectives; a longer value permits slower defaults and more retakes. mp_freezetime is preparation time, so reducing it speeds public play while increasing it gives organized teams more planning time. The decimal 0.25 for mp_buytime represents a quarter of a minute, not 25 seconds. Keep the unit beside every value in your notes to avoid confusing minutes and seconds.

mp_c4timer matters only after a successful plant. A shorter countdown compresses the retake window; a longer one gives defenders more time to move back into position. If a map or plugin imposes its own objective rules, test the resulting timer in a live round rather than assuming the file value won.

Starting money and economy

mp_startmoney determines the cash players receive at the beginning of a session or after the server’s economy rules award a fresh start. The baseline uses 800, a conventional low starting balance that preserves pistol-round decisions. A higher value lets players buy stronger equipment immediately and can be useful for aim practice or casual formats.

Economy changes interact with buy time and round length. If you raise starting money but leave a very short buy window, players may still fail to purchase before movement begins. Conversely, a generous buy period combined with long rounds gives teams more opportunities to make full purchases. Change one variable at a time when diagnosing an unexpected match feel.

Team rules and fair play

Command Values Purpose
mp_friendlyfire 0 off; 1 on Controls whether teammates can damage one another.
mp_autoteambalance 0 or 1 Allows automatic balancing between teams when enabled.
mp_limitteams Number such as 2 Limits how far team sizes may differ.

For an open public server, mp_friendlyfire 0, mp_autoteambalance 1, and mp_limitteams 2 reduce accidental team damage and lopsided queues. Organized matches may deliberately enable friendly fire and use stricter team administration; coordinate those settings with the players before the first round.

Automatic balancing can move players when teams diverge. If a tournament format requires fixed rosters, disable it and enforce team composition through your match procedure instead. The cvars regulate server behavior; they do not replace an administrator watching for deliberate imbalance.

Cheats and consistency checking

Keep sv_cheats 0 for normal play. Setting it to 1 is intended for controlled private testing and exposes cheat-related commands; never enable it on a public match server.

HUANUO FlowLift™ Dual Monitor Stand, Fully Adjustable Gaming Monitor Desk Mount for 13–32″ Computer Screens, Full Motion VESA 75x75/100x100 with C-Clamp & Grommet Base, Each Arm Holds 4.4 to 19.8 lbs
  • Compatible with Wide Screens - To ensure compatibility with the dual monitor mount, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 4.4 to 19.8 lbs. Third, the back of the monitor screen must have VESA mounting holes with a pitch of 75x75mm or 100x100mm.
  • Regarding the compatibility with desks - Your desk must meet three conditions at the same time: First, desk material: Only wooden desks are recommended, plastic or glass desks cannot be used. Second, desk thickness range: 0.59" - 3.54". Third, the bottom of the desk should not have any cross beams or panels, as this will interfere with installation. We recommend carefully checking that your desk and monitors meets all above conditions before purchasing.
  • Dual C-Clamp Hold - Worried your dual monitors might wobble or slip? Our upgraded base uses a larger platform plus a dual C-clamp structure to lock the dual monitor arm firmly to your desk. Each arm safely keeps your screens steady while you type, click and game—no shaking, no sliding, just a clean and secure setup you can trust every day.

  • Full-Motion Adjustment For Comfortable View - Pull the screen closer when you’re deep in a spreadsheet, push it back to watch videos, or rotate to portrait for coding — moving everything smoothly with just one hand. The monitor stand offers +85°/-50° tilt, ±90° swivel and 360° rotation. Raise your monitor up to 15.75″ to support a healthy sitting posture. Whether you’re working from home, gaming through the night, or switching between video calls and documents, getting the screens to your natural line of sight helps relieve neck, shoulder and back strain so you can stay focused longer with less fatigue.
  • Keep Your Desk Organized: By lifting both screens off the desktop, this dual monitor stand opens up valuable space for your keyboard, notebook, docking station or a simple, clutter-free work area. Built-in cable management guides wires along the arms, keeping cords out of sight and out of the way. Enjoy a tidy, modern workstation that looks as good as it feels to use.

sv_consistency 1 enables consistency checking. This helps the server reject incompatible client assets or modified files that conflict with required resources. Custom maps, sound packs, and gameplay plugins can legitimately need different handling, so test a custom content package with the intended clients before opening the server. If players receive consistency errors, identify the named resource and make sure everyone is using the same map and files rather than disabling checks blindly.

Useful round and spectator controls

Some command guides also document mp_fadetoblack and mp_forcecamera. These are useful for competitive or spectator-focused formats: fade-to-black can hide a dead player’s view, while force-camera settings can restrict what eliminated players observe. Their exact behavior can vary with the game build and plugins, so add them only after checking a test round.

Restart controls such as mp_restartgame can reset a match after configuration changes. A restart affects players immediately; announce it before using it on a live server. Use a map change or a full process restart when a plugin only reads its settings during initialization.

How to apply edits without restarting HLDS

  1. Stop or pause administrative changes long enough to avoid editing while another process is overwriting the file.
  2. Open <HLDS install>/cstrike/server.cfg in a plain-text editor.
  3. Change one group of settings, preserve the command spelling, and save the file as UTF-8 or another plain-text format supported by your host.
  4. From the server console, run exec server.cfg.
  5. For remote administration, authenticate through RCON and run rcon exec server.cfg. Keep the RCON password private; it is not part of the example command.
  6. Check the console output for unknown-command or malformed-value messages, then verify the live cvar with the corresponding command, such as mp_roundtime or sv_lan.
  7. If a plugin or map immediately changes the value again, inspect that mod’s configuration and load order. The last command executed normally wins.

Reloading applies cvars, but it does not guarantee that every command takes effect mid-round. A round restart may be needed for timing changes, and a full server restart may be required for settings read only during startup.

Vanilla servers, bots, and mods

Vanilla CS 1.6 does not include built-in bots. Bot play requires a mod such as ZBot or PODBot. Bot commands therefore are not universal server.cfg commands: place them in the mod’s documented configuration section and follow that mod’s syntax.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Keep the universal file focused on HLDS and game cvars. Separate mod-specific files make upgrades safer and help you determine whether a changed value came from server.cfg, a bot package, an AMX-style plugin, or a map configuration. When a mod supplies a command with the same name as a stock cvar, use the mod’s documentation and verify the final value in the server console.

Three practical profiles

Profile Key choices Why use it
Open public sv_lan 0, blank sv_password, mp_friendlyfire 0, balancing enabled Easy discovery and forgiving team play.
Private scrim Non-empty sv_password, optional friendly fire, fixed teams, announced restarts Restricts access and supports organized rules.
LAN test sv_lan 1, small maxplayers, short test rounds Validates maps, plugins, and timing before internet hosting.

These are operating profiles, not extra commands. Start with the baseline, select the profile closest to your session, and record every deliberate deviation so another administrator can reproduce the match.

Troubleshooting checklist

  • Changes disappear after a restart: confirm the file is in the live instance’s cstrike directory and is named exactly server.cfg.
  • The server is invisible to remote players: check that sv_lan 0 is loaded, then verify network forwarding and the host’s firewall separately.
  • Players cannot join: inspect sv_password for an unintended value and check that maxplayers has not filled all slots.
  • A command is reported as unknown: the command may belong to a mod, not vanilla CS 1.6, or may be unavailable in that server build.
  • Timing feels unchanged: run the cvar by itself in the console to read the active value, restart the round, and check whether a plugin overwrote it.
  • Clients receive consistency errors: synchronize map and custom assets first; do not turn off consistency checking until you understand which file differs.
  • Reload causes confusion: announce exec server.cfg and any restart, because some settings alter the next round while others affect players immediately.
