Q2Admin

Q2Admin is a management and security addon for Quake 2 servers. It acts as a proxy game module; the Quake 2 server loads q2admin as its game library and q2admin will open the actual game library and proxy between the two. This allows q2admin to inspect and alter much of the data between client and server on the fly.

Compiling

Linux

Simply run make in the mod source directory

Windows (via MinGW)

Edit .config-win32mingw file to suit your environment and rename it to .config. Then run make to build your DLL.

Configuration

• Copy all the .cfg files from the runtime-config directory to your mod directory.
• Edit q2admin.cfg to suit your needs.
• Inform q2admin what the actual game library is.
  • Either set the gamelibrary option in q2admin.cfg (recommended)
  • Or specifically name the real game library: game{arch}.real.{ext}
    • Linux libraries have a .so extension while Windows uses .dll
    • For 32-bit systems the architechture should be x86
      • Older R1Q2 and 3.2[01] servers will probably look for i386 for arch
    • For 64-bit systems, the arch will be x86_64
    • Examples:
      • 64-bit Linux: gamex86_64.real.so
      • 32-bit Windows: gamex86.real.dll
      • Ancient Linux: gamei386.real.so
    • You cannot mix architectures. The Quake 2 server, q2admin, and the mod all need to either by compiled for 32 or 64 bit. Unfortunately many mods are only available as compiled binaries, the source code is not available or long lost. So depending on what mod you want to run, that will almost certainly dictate what architecture you'll need to run.
  • Or use +set gamelib <libraryname> starting your Quake 2 server.
• Edit each of the q2a_*.cfg files to setup the features you need.

Dependencies

1. libcurl
2. libssl
3. libcrypto
4. zlib
5. libpthread

All dependencies are included and statically linked. The resulting binary is about 8MB, most of which is related to libcrypto. This is unfortunately required for the Cloud Admin connection (authentication and transit encryption).

entity_classname_offset	number	280	What byte offset can the classname property be found in the edict_s struct? Since most of the edict_s struct is opaque and filled in by the game library, it's not possible for q2admin to know where that value is located. This value can be different for each game mod. Using an incorrect value here can lead to crashes, especially if you're doing entity substitution/blocking. Common values: baseq2 = 280 opentdm = xxxxxx

http_verifyssl	bool	yes	When downloading a file via https, verify the TLS certificate is signed, valid, trusted and the common name on the cert matches the domain in the URL. Q2admin doesn't download and execute arbitrary files from the internet, so certificate issues are fairly low risk. Try disabling this if you're having trouble fetching https files (especially with https redirects)
impulsestokickon	string	""	A comma-separated list of impulse values that will earn a player a kick. These values are what zbot's use for their onscreen menu. Default is empty, but a good value for this is "169, 170, 171, 172, 173, 174, 175"
inverted_command[1-4]	string	""	Private commands stuffed to a player as part of the standard proxy check.
ip_limit	number	0	The number of players allowed from the same IP address. Exceeding this limit kicks the player. 0 = unlimited/no filtering
ip_limit_vpn	number	0	The number of players allowed from the same VPN provider. The ASN number of the provider is used here, so players can be on discontiguous netblocks and still be kicked. 0 = unlimited/no filtering
ipbanning_enable	bool	yes	Enable the functionality of banning players based on their IP address.
kickonnamechange	bool	no	If a player successfully joins with a password-protected name, kick them if they change names after connecting.
lock	bool	no	lockdown mode, prevent anyone from joining. This is presumablity to allow for some kind of maintenance without player interference.
lockoutmsg	string	"This server is currently locked."	The message to display to clients attempting to connect while the server is locked.
lrcon_timeout	number	2	The seconds from now that an lrcon random password/request is valid for.
mapcfgexec	bool	no	On new map (or connect), stuff these commands to player: - exec mapcfg/{oldmapname}-end.cfg - exec mapcfg/{newmapname}-pre.cfg
maxclientsperframe	number	100	The number of players q2admin can deal with per server frame. This assumes default of 10HZ, don't touch this unless you know what you're doing
maxfps	number	0	The maximum value for cl_maxfps cvar allowed on this server. It should be evenly divisible by 1000, 125 is a good value. I've seen 150 used on map q2duel5 for making some otherwise impossible jumps. Value of 0 means no max.
maximpulses	number	1	Max impulses before taking action
maxmsglevel	number	3	Max value allowed for the msg userinfo variable.
maxrate	number	0	Max value allowed for the rate userinfo variable. Value of 0 means no limit.

minfps	number	0	The minimum value allowed for the cl_maxfps cvar
msec_action	number	2	What action should be taken if there are msec violations? 0 = legacy behavior, kick if over limit 1 = do nothing 2 = announce and kick the player
msec_max_allowed	number	5600	The maximum cumulative msec consumption for msec_timespan amount of time. This value should be (1000 * msec_timespan) * 1.12 -ish. The 1.12 multipier allows for some slop. This is a similar calculation to how q2pro allocates msec to clients but on a shorter timespan.
msec_max_violations	number	2	How many violations allowed before taking action.
msec_min_required	number	0	This is the minimum msec consumption required for the msec_timespan amount of time. If you really want to get strict, set this to (1000 * msec_timespan) * 0.88 -ish. Modified clients can underflow their msec consumption in order to bank it and use it later in the same msec_timespan for a speed boost. Be aware packet loss can affect this causing a player to be in violation if their move packet is never received, so they could be kicked simply for having poor network performance. Use at your own risk.
msec_timespan	number	5	Span of seconds to evaluate msec consumption. The smaller the value the more unforgiving to things like packet loss and network jitter. The larger the span the more accurate reading you get, but that delays the ability to take action for that amount of time.
namechangefloodprotectmsg	string	"%s changed names too many times."	The message the player will see when they change their name too many times
nickbanning_enable	bool	yes	Enable the ability to ban based on player name
numofdisplays	number	4	How many times to in a row to broadcast that a player was caught cheating
printmessageonplaycmds	bool	yes	Display when a player uses one of the play_* commands. This command is useless for the actual play command because that command is kept in the client and not sent to the game library anymore with modern clients. Ancient 3.20 clients still send it though.
private_command[1-4]	string	""	Private commands stuff to a player as part of the standard proxy check
private_command_kick	bool	no	If responses to the private commands are not received, kick the player.
proxy_bwproxy	number	1	Check for bwproxies
proxy_nitro2	number	1	Check for nitro2 proxies
q2adminrunmode	number	100	100 = fully operational, 0 = passthru - don't touch this value
q2a_command_check	bool	false	???? (seemingly unused?)
randomwaitreporttime	number	55	Used for seeding a random delay time for proxy checking. Only used if zbotdetectactivetimeout is set to -1.
rcon_random_password	bool	yes	Change the actual rcon password to random string and back for lrcon usage
rcon_insecure	bool	yes	If no, lrcon commands are executed directly on the server rather than let the client execute it, this means the output is never seen by the client.
reconnect_address	string	""	The IP/hostname to force the client to reconnect to.
reconnect_checklevel	number	0	How specific to do userinfo checking for reconnecting player. Positive integer means check the keys, 0 means just compare the whole userinfo string (different ordering will cause non-match)
reconnect_time	number	60	The max time to wait for a reconnect
say_group_enable	bool	no	Allow players to send chats to a specific group of other players
say_person_enable	bool	yes	Allow players to send chats to another specific player, not everyone
serverinfoenable	bool	yes	Add q2admin version to the server info string so it will appear in server browsers

skinchangefloodprotectmsg	string	""	Message to display to players who change their skin too many times
skincrashmsg	string	""	Message to display to players who attempt to use a special skin designed to crash the server
soloadlazy	bool	no	Linux only. Sometimes the forward mod doesn't load properly and crashes. Try setting this to fix this behavior.
spawnentities_enable	bool	no	Enable entity-related stuff like swapping or disabling
spawnentities_internal_enable	bool	no	Whether q2admin will run it's own SpawnEntities function before forwarding to the real game library.
speedbot_check_type	number	3	Whether or not to display when a speedbot is detected
swap_attack_use	bool	no	If attack input is detected, change it to use. Vice-versa
timers_active	bool	no	Whether q2admin timer support is enabled
timers_max_seconds	number	180	The largest timer value allowed
timers_min_seconds	number	10	The smallest timer value allowed
timescaledetect	bool	yes	Monitor players' timescale variable. This is a cheat-locked cvar that would allow players to move faster
timescaleuserdisplay	string	???	Message to send player if their timescale is greater than 1.0
userinfochange_count	number	40	Players changing userinfo more than this will result in being kicked
userinfochange_time	number	60	The timespan for flooding the server with userinfo changes

zbotdetect	bool	yes	Detect zbots
zbotdetectactivetimeout	number	0	Number of seconds to delay zbot proxy checking. Use -1 for random time linked to randomwaitreporttime
zbotuserdisplay	string	"%s is using a client side proxy."	The message sent to users when they're detected as a zbot

Commands

ban

Add an entry to the banlist. The action of each entry can either be exclusionary (keeping players out (the default)) or inclusionary (allowing players in). Every filter defined in a ban command must match in order for the action to apply, if not, the opposite action is applied. Ban checking stops at the point where the first entry matches a player. This means exceptions (inclusion rules meant to override some other exclusion rule) have to match first. Ban entries are checked from newest to oldest or in the context of the banlist file, from bottom up. New ban commands are checked against all currently players immediately unless the NOCHECK parameter is used.

Related commands: listbans, delban

Player attributes available for filtering:

• Player name
• IP address
• ASN
• Player client version

Additional controls

• Password (inclusionary)
• Max number of connections (inclusionary)
• Custom messages to affected players
• Text flood controls
• Time-to-live
• Materialization

chatban

Add an entry to the chatban list. This acts just like the ban command for chat messages.

Related commands: delchatban, listchatbans

sv !CHATBAN [LIKE/RE(LIKE)] xxx [MSG xxx] [SAVE [MOD]]

Examples:
// don't allow players to say "fart", use the default msg
sv !chatban LIKE "fart" 

// don't allow players to say "fart" and the friend "f4rt"
sv !chatban RE ".*f[a4]rt.*" MSG "potty talk not allowed"

chatfloodprotect

Set the params for what constitutes a chat flood:

1. The number of chat messages to trigger
2. The number of seconds those messags are seen in
3. The number of seconds that player will be silenced

// sending 10 chats in 5 seconds will result in a 30 second mute
sv !chatfloodprotect 10 5 30

checkvarcmd

Manually add an entry to the checkvar list. These ensure client-side variables are set to specific values or fall within specific ranges. If a value does not match the client will be stuffed the appropriate value.

Related commands: checkvardel

Syntax:
sv !checkvarcmd [CT/RG] "variable" ["value" | "lower" "upper"]

CT = constant value
RG = range

// force cl_maxpackets to be between 30-100
sv !checkvarcmd RG cl_maxpackets 30 100

// force gl_shadows to 1
sv !checkvarcmd CT gl_shadows 1

checkvardel

Delete a checkvar entry from the list. The only arg is the index number of the entry to remove.

sv !checkvardel 2

clearlogfile

Delete all entries in a particular log file. The only arg is the number of the log file.

sv !clearlogfile 3

clientchatfloodprotect

Set custom chat flood protection for a specific player

sv !clientchatfloodprotect [CL # | name] [num] [secs] [silence]

Specify the client either by number using CL or directly by name. Num is the number of chat messages seen within secs seconds to trigger the rule resulting in this player being muted for silence seconds.

// Silence player #3 for 1 minute if they say 20 chats in 7 seconds
sv !clientchatfloodprotection CL 3 20 7 60

// Silence claire for 30 seconds if they say 10 chats in 5 seconds

Enable/Disable or check the status of the Cloud Admin server connection

// enable connecting to cloud admin server
sv !cloud enable

// disable connecting to CA
sv !cloud disable

// show the connection status
sv !cloud status

cvarset

Set (or unset) a CVAR to a specific value on the server

// set the variable "foo" to value "bar"
sv !cvarset "foo" "bar"

// unset the variable "foo"
sv !cvarset "foo" none

delban

Delete a ban entry from the list. The only arg is the number of the ban entry to remove. Related commands: ban, listbans

disabledel

Delete a disabled command from the list. Takes the entry number as an arg. Related commands: disablecmd

// remove entry #5
sv !disabledel 5

displaylogfile

Spit out an entire log file to the server console. In order to not DOS the server, it spits out a single line per server frame. Quake2 server logs can grow to absurd sizes, displaying entire log files is really dumb, don't use this command! Once the process is started, there doesn't seem to be a way to stop it.

// display the whole file for log #12 one line at a time
sv !displaylogfile 12

floodcmd

Add an entry to the floodcmd list. The floodcmd entry is for applying normal flood rules to any arbitrary command. Only the first part of the command is matched, not any arguments. Do not use this for any command that outputs chat messages (say, say_team, say_person, etc).

sv !floodcmd [SW/EX/RE] "command"

SW = starts with
EX = exact
RE = regular expression

// add floodcmd for the play command
sv !floodcmd EX "play"

// any command starting with "play_"

Logtypes:

• ADMINLOG
• BAN
• CHAT

sv !logevent view chat

// setup a new log for chatban logtype
sv !logevent edit chatban log yes logfiles "chatbans.log" format "%s"

// disable and existing log definition for chatbans
sv !logevent edit chatban log no

logfile

View/edit all log file definitions. Unclear how this is different from logevent command.

sv !logfile [view [#]] / [edit # [mod] [filename]] / [del #]

// list all logfiles
sv !logfile view

// change the filename for logfile 2 and keep it in the mod directory
sv !logfile edit 2 yes newlogname.log

// delete the log definition for log 3
sv !logfile del 3

lrcon

Add limited-rcon entries in the current list. An lrcon entry is a least-privilege implemention of rcon passwords that are only allowed to run very specific commands. You're able to create up to 1024 of them. You can use these add moderators to watch over your server who can only do things like change maps or mute/kick players. You can also simply revoke this access and never have to reveal/change your actual rcon password. This functionality has since been integrated into q2pro and r1q2 (I think), so mileage may vary.

The entire command (including args) is evaluated

Related commands: listlrcon, lrcondel

sv !lrcon [SW/EX/RE] "password" "command"

SW = starts with
EX = exact
RE = regular expression

// Allow changing map to only q2dm1 through q2dm8 (as a regular expression) with password "dingleberry"
sv !lrcon RE "dingleberry" "gamemap q2dm[1-8]"

// allow the map to be changed to anything (note the space)
sv !lrcon SW "dingleberry" "gamemap "

// allow user to see the status output (to see ips)
sv !lrcon EX "1ngr0wn" "status"

lrcondel

Delete an lrcon entry from the list. To view the current list use the listlrcon command.

// delete lrcon entry #4
sv !lrcondel 4

mute

Toggle a player's ability to speak for a specific timespan or for the duration of their playing session. If the player is already muted, they will be unmuted. The time arg is not needed to unmute.

Related commands: stifle

sv !mute [CL # | [LIKE] name] [[time in secs]|PERM] 

For a permanent mute, use "PERM" as the duration, otherwise it's a length of seconds. Permanent is relative here, if the player quits and rejoins, the mute will be gone.

// mute player 3 for 30 seconds
sv !mute CL 3 30

// mute claire for this whole playing session
sv !mute claire PERM

// unmute claire if they're already muted
sv !mute claire

namechangefloodprotect

Set the global parameters for name-change flooding. These apply to all players but are tracked individually, so one player triggering this rule will not affect other player's ability to change names.

sv !namechangefloodprotect num_changes time_span prevention_time

// Set limits to 5 name changes in 30 seconds, prevent change again for 5 minutes
sv !namechangefloodprotect 5 30 300 

readloadbanfile

Reread the banfile from disk. Useful to rehash the bans without needing to restart the server. This will reload ALL banlist files q2admin knows about, including:

1. any q2a_ban.cfg file in the main q2 directory
2. any q2a_ban.cfg file in the mod directory
3. any remote (http) ban files included in 1 & 2.

Ban file processing is recursive, so creating an include-loop will result in a very bad day.

sv !reloadbanfile

reloadanticheatlist

Reread the anticheat exception list. This will first take any anticheat exceptions from a remote exception file (if one is defined), and then the the local config file.

sv !reloadanticheatlist

reloadexceptionlist

This is an alias for reloadanticheatlist

sv !reloadexceptionlist

reloadhashlist

Reread the anticheat hash list files:

1. anticheat-cvars.txt
2. anticheat-hashes.txt
3. anticheat-tokens.txt

sv !reloadhashlist

reloadcheckvarfile

resetrcon

Reset the server's rcon password to it's original value. Every time an lrcon password is used, the real rcon password is changed to something random to prevent sniffing traffic to see the real rcon password. It's set back automatically after a timeout, but this command forces that reset.

sv !resetrcon

say_group

Send a private chat msg to a select group of players instead of to everyone.

Related commands: say_person, say_person_low

// say hi to players 0, 4, and 5
sv !say_group CL 0 + 4 + 5 "hey there"

// say hi to player 2
sv !say_person CL 2 "yooooo!"

say_person_low

Send a message to a particular player as a PRINT_LOW message. This will not highlight the message as chat and will not trigger the chat sound in-game.

Related commands: say_person, say_group

sv !say_person_low CL 3 "The white zone is for loading and unloading only"

setadmin

Seemingly unimplemented...

skinchangefloodprotect

Set parameters around skin changes

// if someone changes skins 3 times in 10 seconds, prevent changes for 5 minutes
sv !skinchangefloodprotect 3 10 300

spawncmd

Add an entry to block the spawning of a particular entity. This won't despawn entities that already linked, but can prevent them from respawning.

Related commands: listspawn, spawndel

sv !spawncmd [SW/EX/RE] "classname"

SW = starts with
EX = exact
RE = regular expression

// prevent health from spawning
sv !spawncmd SW "health_"

// make it dark (untested probably won't work)
sv !spawncmd RE ".*light.*"

spawndel

Remove a specific disabled spawn entry from the list. This isn't persistent, restarting the server will reload spawncmds from disk and restore the entry.

// remove spawn entry #4
sv !spawndel 4

stifle

Half-mute for players. This allows the player to say one thing every minute.

sv !stifle [CL # | name] length_in_secs

The length_in_secs arg is how long the half-mute applies to the player, not the length of time between allowing the single chat message.

// half-mute for player named 888 for the next 10 minutes
sv !stifle 888 600

// half-mute player 0 for the next 30 minutes
sv !stifle CL 0 1800
