Settings

ReHLDS adds a set of server console variables (cvars) on top of the standard HLDS ones, mostly for anti-cheat/anti-abuse tuning, networking, and behavior fixes. Set them in server.cfg or any config executed at startup.

Cvars

Cvar	Default	Description
sv_auto_precache_sounds_in_models	0	Automatically precache sounds attached to models.
sv_delayed_spray_upload	0	Upload custom sprays after entering the game instead of when connecting. Increases upload speed.
sv_echo_unknown_cmd	0	Echo in the console when a client tries to execute an unknown command.
sv_rcon_condebug	1	Print rcon debug output in the console.
sv_force_ent_intersection	0	Used by third-party plugins to force collision of SOLID_SLIDEBOX entities.
sv_rehlds_force_dlmax	0	Force a client's cl_dlmax cvar to 1024, avoiding excessive packet fragmentation.
sv_rehlds_hull_centering	0	Use the center of the hull instead of a corner.
sv_rehlds_movecmdrate_max_avg	400	Max average level of "move" commands allowed before a ban.
sv_rehlds_movecmdrate_avg_punish	5	Ban time in minutes for exceeding sv_rehlds_movecmdrate_max_avg (0 = permanent, negative = kick).
sv_rehlds_movecmdrate_max_burst	2500	Max burst level of "move" commands allowed before a ban.
sv_rehlds_movecmdrate_burst_punish	5	Ban time in minutes for exceeding sv_rehlds_movecmdrate_max_burst (0 = permanent, negative = kick).
sv_rehlds_send_mapcycle	0	Send mapcycle.txt in the server info message (matches original HLDS behavior; unused by the client).
sv_rehlds_stringcmdrate_max_avg	80	Max average level of "string" commands allowed before a ban.
sv_rehlds_stringcmdrate_avg_punish	5	Ban time in minutes for exceeding sv_rehlds_stringcmdrate_max_avg (0 = permanent, negative = kick).
sv_rehlds_stringcmdrate_max_burst	400	Max burst level of "string" commands allowed before a ban.
sv_rehlds_stringcmdrate_burst_punish	5	Ban time in minutes for exceeding sv_rehlds_stringcmdrate_max_burst (0 = permanent, negative = kick).
sv_rehlds_userinfo_transmitted_fields	""	Only userinfo keys listed here are transmitted to clients over the network. Empty means all fields are transmitted (except keys prefixed with _). Prefix each key with a backslash, e.g. \name\model\*sid\*hltv\bottomcolor\topcolor. See Userinfo keys for the full reference.
sv_rehlds_attachedentities_playeranimationspeed_fix	0	Fixes a gait animation speed bug that occurs when a player has attached entities (aiments). Can cause animation lag when cl_updaterate is low.
sv_rehlds_maxclients_from_single_ip	5	Limit simultaneous connections from a single IP address (does not affect already-connected players).
sv_rehlds_local_gametime	0	Reduces perceived "lag" when the same map runs for a long time.
sv_rehlds_allow_large_sprays	1	Allow custom logos larger than 64x64.
sv_use_entity_file	0	Controls use of a custom entity file per map (maps/[map name].ent). 0 = original entities, 1 = use .ent files from the maps directory, 2 = use .ent files and create one if it doesn't exist.
sv_usercmd_custom_random_seed	0	Populate an additional random seed independent of the client.
sv_net_incoming_decompression	1	Decompress incoming compressed file-transfer payloads.
sv_net_incoming_decompression_max_ratio	80.0	Max allowed ratio between compressed and uncompressed data for file transfer, 0–100. A ratio close to 90 indicates large uncompressed data with low entropy.
sv_net_incoming_decompression_max_size	65536	Max allowed size in bytes for decompressed file-transfer data, 16–65536.
sv_net_incoming_decompression_min_failures	4	Minimum decompression failures required before a connection is flagged for potential punishment, 0–10.
sv_net_incoming_decompression_max_failures	10	Max decompression failures allowed within the tracking window before action is taken, 0–10.
sv_net_incoming_decompression_min_failuretime	0.1	Time window in seconds, 0.1–10.0, within which decompression failures are tracked.
sv_net_incoming_decompression_punish	-1	Ban time in minutes for malformed/abnormal bzip2 fragments (0 = permanent, negative = kick).
sv_tags	""	Comma-delimited list of "gametags" for the server, used for filtering in matchmaking/server-browser interfaces.
sv_filterban	1	IP filtering mode. -1 = reject all players unconditionally, 0 = no checks, 1 = kick players matching an IP filter/ban entry.
sv_rehlds_movecmd_max_ticks	24	Max number of movement commands the server processes from a single player in a single frame (commands, not packets).
sv_rehlds_movecmd_max_null_streak	0	Max allowed consecutive movement commands with zero time duration (empty commands). 0 disables the check.
sv_rehlds_movecmd_clamp_interp	1	Block movement commands with an out-of-range ex_interp value.
sv_rehlds_movecmdtime_samples	120	Number of frames used to average a client's movement speed. Higher = more accurate but slower detection.
sv_rehlds_movecmdtime_max_error	300	How far (in ms) a client's internal game clock may drift from the server's clock before speed is evaluated. Penalties apply only if sv_rehlds_movecmdtime_max_scale / _min_scale are also violated.
sv_rehlds_movecmdtime_max_scale	3.0	Max client base game-speed ratio. Clients speeding up beyond this receive warnings.
sv_rehlds_movecmdtime_min_scale	0.5	Min client base game-speed ratio. Clients slowing down below this receive warnings.
sv_rehlds_movecmdtime_max_warnings	-1	Max allowed speedhack/slowmo warnings before punishment. -1 disables detection.
sv_rehlds_movecmdtime_punish	-1	Punishment for speedhacking/slowing (-1 = kick, 0 = permanent ban, negative = kick).
sv_reconnect_timeout	30	Hard deadline in seconds for a client to re-initiate its connection after a level change, independent of netchannel activity. Closes a phantom-slot exploit where a cheat blocks the reconnect command while keeping the netchannel alive so sv_timeout never fires. 0 disables it.

note

sv_rehlds_userinfo_transmitted_fields is the setting most commonly used together with privacy/anti-cheat configurations. See the Userinfo keys wiki page for value type, default transmission, and privacy notes for every standard key.

Files

Cvar	Default	Description
listipcfgfile	listip.cfg	File used for permanent IP bans.
syserror_logfile	sys_error.log	File used for the system error log.

Console commands

Command	Description
rescount	Prints the total count of precached resources in the server console.
reslist <sound | model | decal | generic | event>	Prints the precached resources of the given type. Useful for managing resources and the GoldSrc precache limits.
rcon_adduser <ipaddress/CIDR>	Adds an IP address or CIDR range to the RCON user list, granting it privileged console access. Without any RCON users, anyone with a valid password can use RCON.
rcon_deluser <ipaddress> {removeAll}	Removes an IP address or CIDR range from the RCON user list.
rcon_users	Lists all IP addresses and CIDR ranges in the RCON user list.
