| Variable | Value | Default | Description |
|---|
| sv_password |

|
Password required to enter the server. Similar to the 'password' cvar provided by some mods, but at the server level. |
| sv_restartmap |
|
|
Map name to restart the server with if the Game DLL quits due to a handled errror (eg, no free edicts). If not specified, the server will stop running if the Game DLL quits. Specify only the map name, eg q2dm1. |
| sv_filter_userinfo |
0 (Disabled)
1 (Enabled (normal))
2 (Enabled (strict))
|
0 |
Filter the client userinfo string to remove unprintable characters. The normal filter filters out low ASCII values, the strict filter filters both low and high (colortext) values. |
| sv_filter_stringcmds |
0 (Disabled)
1 (Enabled (normal))
2 (Enabled (strict))
|
0 |
Filter client commands to remove unprintable characters. The normal filter filters out low ASCII values, the strict filter filters both low and high (colortext) values. |
| sv_blackholes |
0 (Disabled)
1 (Enabled)
|
1 |
Control the use of the automatic blackholing (IP blocking) system for clients who try to do illegal things. |
| sv_allownodelta |
0 (Disabled)
1 (Enabled)
|
1 |
Allow use of cl_nodelta. If a client is using cl_nodelta, they will require much more bandwidth than a client that is using deltas. |
| sv_iplimit |
|
3 |
Maximum number of players allowed to connect from the same IP address. |
| sv_connectmessage |
|
|
A message to show to clients while they are connecting to the server. Supports \n for newline expansion. |
| sv_nc_visibilitycheck |
0 (Disabled)
1 (Hide Entities)
2 (Remove Entities)
|
0 |
Control the use of NoCheat-style visibility checking. This tries to calculate if a player is visible to another player on the server and hides or removes players that aren't visible, reducing the effectiveness of wallhacks. However this causes significant CPU load and also produces false positives and causes issues for players with high pings. Not recommended. |

8388608 |
The maximum file size (in bytes) of a file that a client will be permitted to auto download. |
| sv_downloadserver |

|
A URL to a server where clients can download game content over HTTP. See the R1Q2 forum for more information on this feature. |
| sv_download_drop_file |
|
|
The name of a file that if a client tries to download, will kick them from the server. Useful for preventing players who do not have the mod from connecting to the server. Example: models/doomsday/tris.md2. |
| sv_download_drop_message |

Kick players who send more than this number of packets per second. Use zero for no limit. A value of less than 100 is not recommended. |
| sv_randomframe |
0 (Disabled)
1 (Enabled)
|
0 |
Randomize the server frame number when loading a map to thwart map timers. |
| sv_uptime |
0 (Disabled)

Include server uptime in the status response. Use the compact option if the server info string space is limited. |
| sv_gamedebug |
0
1
2
3
4
|
0 |
Enable debug information for the Game DLL. When set to 1, R1Q2 will print a warning whenever the Game DLL does something in an incorrect or dangerous way. Setting this to values higher than 1 will cause a breakpoint to occur depending on the severity of the problem. Setting this to 4 will breakpoint on every single problem. |
| sv_strafejump_hack |
0 (Disabled)
1 (Enabled (p35))
2 (Enabled (forced))
|
1 |
Enable a fix for the 'feature' that causes strafe jumping to sometimes fail and the player becomes stuck to the floor briefly. This is properly supported in protocol 35 (R1Q2, AprQ2, EGL, Q2Pro, Quetoo) clients, but if forced, it will be enabled for all clients. Non-protocol 35 clients may notice small prediction errors whenever this fix takes effect. |
| sv_reserved_slots |
|
0 |
Number of reserved player slots. |
| sv_reserved_password |
|
|
Password required to use a reserved player slot. Clients set this password using the 'password' cvar. |
| sv_allow_map |
0 (Disabled)
1 (Enabled)
|
0 |
Allow use of the 'map' command to change levels. Use of the map command causes a full Game DLL reset, losing any game state. The recommended way to change level is by using the 'gamemap' command. |

1 (Enabled)
|
0 |
Allow players who are still connecting to use commands such as 'say'. Not recommended. |

| sv_calcpings_method |
0 (No ping calculations)
1 (Normal calculations)
2 (R1Q2 calculations)
|
1 |
Control how a player's ping is reported in game. The R1Q2 calculation uses the best ping time from the series of packets received which presents a more accurate ping time, however it is less effected by lag. |
| sv_no_game_serverinfo |
0 (Disabled)
1 (Enabled)
|
0 |
Disallow the Game DLL from setting serverinfo variables. Must be set before the Game DLL loads. Use this if you get 'serverinfo string length exceeded' a lot. |
| sv_ratelimit_status |
|
15 |
Maximum number of status requests to reply to per second. |
| sv_new_entflags |
0 (Disabled)

| sv_validate_playerskins |
0 (Disabled)
1 (Enabled)
|
1 |
Validate the structure of skins set by the client 'skin' cvar. Skins must be in the form model/skin or they will be replaced by male/grunt. |
| sv_idlekick |
|
0 |
Number of seconds before an idle player is kicked from the server. Zero means no limit. |
| sv_packetentities_hack |
0 (Disabled)
1 (Enabled (normal))
2 (Enabled (zlib))
|
0 |
Under heavy activity, the entity updates may not fit in to a single packet. If this occurs, the packet is dropped and the client receives a 'freezing' effect. This cvar allows partial amounts of entities to be sent. If set to 1, the packet will simply be cut off and sent if it gets too large. If set to 2, zlib compression is first attempted to compress the packet into a usable size (for protocol 35 clients only). |
| sv_entity_inuse_hack |
0 (Disabled)
1 (Enabled)
|
0 |
Some mods to not properly clear the state of unused entities, and they may still be sent over the network. If this is enabled, entities that are marked as 'not in use' will never be sent over the network, regardless of state. |
| sv_force_reconnect |
|
|
Force a reconnect on connection to this IP:port or hostname. Useful for bypassing some proxy-based cheats. |
| sv_enforcetime |
0 (Disabled)
1 (Limit only)
2 (Kick (aggressive))
5 (Kick (normal))
10 (Kick (safe))
|
1 |
Enable speed cheat detection / limiting. If set to 1, any player exceeding the speed limit will be frozen in place. Values higher than 1 will kick players for exceeding the speed limit, higher values are less sensitive. Note that lag may also be responsible for false detection of speed cheats, so be conservative with the kick threshold. |
| sv_download_refuselimit |
|
0 |
Refuse auto downloading if this many players are currently connected. Zero for no limit. |
| sv_blackhole_mask |
|
32 |

|
0 |
Maximum number of duplicate packets a client can request with the 'packetdup' command to help overcome packet loss. |
| sv_func_entities_hack |
0 (Disabled)
1 (Enabled)
|
0 |
Attempt to fix sound origins from the Game DLL for elevators and perform server-side attenuation calculations for elevators and doors. If enabled, this will save bandwidth and provide more accurate sound spatialization for these entities. TEST BEFORE USING as some mods may already provide such a fix or may be incompatible with this setting. |
| net_maxmsglen |
|
1390 |
Maximum packet size that may be requested by a client. If you set this to zero, the highest possible size will be allowed. If your network connection / router supports it, it is recommended that you set this to zero to allow for large packets where required by protocol 35 clients. Please test this feature before keeping it set as it may not be immediately obvious if your network connection doesn't support it until a client which also has net_maxmsglen 0 tries to connect. |
| net_ignoreicmp |
0 (Disabled)
1 (Enabled)
|
0 |
Ignore ICMP unreachable messages. On Windows and Linux, if the server receives an ICMP unreachable message, it will look up the appropriate client and kick them with the message 'connection reset by peer'. This helps to remove client that have crashed without waiting for the full client timeout. |
| sv_anticheat_required |
0 (Disabled)
1 (Optional)
2 (Forced)

0 |
Control use of the r1ch.net anticheat module for clients. You must have access to the anticheat server before using this cvar. See the R1Q2 forums for further information. |
| sv_anticheat_error_action |
0 (Fail-open)
1 (Fail-closed)

| sv_anticheat_badfile_action |
