QStat is a command-line program that displays information about Internet game servers. The servers are either down, non-responsive, or running a game. For servers running a game, the server name, map name, current number of players, and response time are displayed. Server rules and player information may also be displayed.
Games supported include Quake, QuakeWorld, Hexen II, Quake II, HexenWorld, Unreal, Half-Life, Sin, Shogo, Tribes, Tribes 2, Quake III: Arena, BFRIS, Kingpin, and Heretic II, Unreal Tournament, Soldier of Fortune, Rogue Spear, Redline, Turok II, Blood 2, Drakan, KISS, Nerf Arena Blast, Rally Master, Terminous, Wheel of Time, and Daikatana. Note for Tribes 2: QStat only supports Tribes 2 builds numbered 22075 or higher.
Some games use query protocols compatible with an existing game. These servers can be queried using the flags for the compatible game. For instance, Turok2 should work using the -uns flag. Unreal Tournament is also supported by the -uns but is not really a different game. You can distinguish Unreal Tournament games with the "minnetver" server rule (standard Unreal servers have a "mingamever" server rule).
The Quake servers can be divided into two categories: POQS (Plain Old Quake Server) and QuakeWorld. Quake shareware, Quake commercial (from CD), winquake, winded, unixded, and Hexen II are all POQS. The various versions of QuakeWorld and Quake II use a QuakeWorld type server. The distinction is based on network protocol used to query the servers, and affects the kind of information available for display.
The different server types can be queried simultaneously. If QStat detects that this is being done, the output is keyed by the type of server being displayed. See DISPLAY OPTIONS.
The game server may be specified as an IP address or a hostname. Servers can be listed on the command-line or, with the use of the -f option, a text file.
One line will be displayed for each server queried. The first component of the line will be the server's address as given on the command-line or the file. This can be used as a key to match input addresses to server status. Server rules and player information are displayed under the server info, indented by one tab stop.
QStat supports two additional display modes: raw and templates. In raw mode, the server information is displayed using simple delimiters and no formatting. This mode is good for programs that parse and reformat QStat's output. The template mode uses text files to layout the server information within existing text. This is ideal for generating web pages. The raw mode is enabled using the -raw option and template output is enabled using -Ts.
These options select which servers to query and what game type they are running. Servers are specified by IP address (for example: 199.2.18.4) or hostname. Servers can be listed on the command-line or in a file (see option -f.) The game type of a server can be specified with its address, or a default game type can be set for all addresses that don't have a game type.
The following table shows the command-line option and type strings for the supported game types. The type string is used with the -default option and in files with the -f option.
| Option | Type String | Default Port | Game Server |
|---|---|---|---|
| -qs | qs | 26000 | Quake |
| -h2s | h2s | 26900 | Hexen II |
| -qws | qws | 27500 | QuakeWorld |

| -gsm | gsm | 28900 | Gamespy master |
| -gps | gps | - | Game using "Gamespy style" protocol |
The command-line options can be specified multiple times, one for each server to be queried.
A broadcast query is specified by prefixing an address with a '+' (plus sign). The address should be 255.255.255.255 or a valid broadcast address for a local network. On Unixes, 'ifconfig -a' will display the broadcast address for all attached networks.
The query argument can also be any string that the Gamespy master responds to. Most of these games support a "standard" server status protocol that I'll call the "Gamespy status protocol". Not surprisingly, it is almost identical to the Unreal server status protocol. This means that QStat can support any game that supports this protocol. In QStat these games are queried using the gps game type. Through experimentation I've found the following query arguments.
| Query Argument | Game |
|---|---|
| roguespear | Rainbow Six: Rogue Spear |
| redline | Redline Racer |
| turok2 | Turok 2: Seeds of Evil |
| blood2 | Blood 2: The Chosen |
| drakan | Drakan: Order of the Flame |
| kiss | KISS Psycho Circus: The Nightmare Child |
| nerfarena | Nerf Arena Blast |
| rally | Rally Masters: Michelin Race Of Champions |
| terminous | Terminous (?) |
| wot | The Wheel of Time |
| daikatana | Daikatana |
t2m,query-arg=value, ...
| Query Argument | Values | Description |
|---|---|---|
| game | mod path | Mod path the server is using. The mod path of unaltered servers is "base". Use query=types to get the list of known game types. |
| mission | Bounty, Capture the Flag, CnH, Deathmatch, Hunters, Rabbit, Siege, TeamHunters | Mission type the server is currently running. Use query=types to get the list of known mission types. |
| minplayers | 0 - 255 | Servers with fewer players than this will not be returned. |
| maxplayers | 1 - 255 | Servers with more players than this will not be returned. |
| regions | list of regions or 0xhex-value | Limit servers to those in the given geographical regions. See Region List table. The regionlist is sent as a bit mask to the Tribes 2 master. If you know the bit mask for a region QStat doesn't support, you can specify the bitmask directly by supplying a hex value: regions=0x11. |
| build | build version # | Only return servers matching this build version number. [4/20/2001] This filter only seems to work if the build version # is 22337. If the filter is 22228, then the master returns 0 servers. This appears to be a bug in the T2 master. |
| status | list of dedicated, linux, nopassword or 0xhex-value | Limit servers to those with these status flags set. The list is
one or more status flags separated by colons (':'). To filter on
dedicated Linux servers, specify status=dedicated:linux If you know a status flag that QStat doesn't support, you can specify the status flags directly by supplying a hex value: status=0x3 |
| maxbots | 0 - 255 | Servers with more bots than this will not be returned. |
| mincpu | 0 - 65535 | Servers with lower CPU speed than this will not be returned. |
| query | types | Get the list of game and mission types. This is not a filter but a different master request. Using this query argument overrides any other query arguments. The list of game and mission types known to the master server will be displayed. In raw mode, the first line is the list of game types and the second line is the list of mission types. There is no output template support for game and mission lists. |
The Tribes 2 master query arguments can be used on the command-line or in a server list file (via the -f option). If the values contain spaces, be sure to quote the arguments for your shell. The second example below demonstrates this usage for most common shells. To query for Capture the Flag servers that have more than 6 players:Region List
The region list is one or more region arguments separated by colons (':'). For example, to filter on North American servers specify regions=naeast:nawest
Region Argument Geography naeast North America East nawest North America West sa South America aus Australia asia Asia eur Europe
qstat -t2m,mission=Capture the Flag,minplayers=6 master-server-ipIf you want to do this in a server list file, that would look like this:
qstat -t2m,mission="Capture the Flag",minplayers=6 master-server-ip
t2m,mission=Capture the Flag,minplayers=6 master-server-ipMaster server filters can be combined with the "outfile" option. Just put outfile some where in the query argument list and put the name of the output file after the master IP address:
t2m,outfile,mission=Siege,minplayers=4 master-server-ip,siegeservers.txtWarning: There is a bug in the 22075 build of Tribes 2 that doesn't return the game name. For those builds, QStat will use the game info in place of the game name. The bug is fixed in the 22228 build. In fixed servers, the game info can be found in the "info" server rule.
The QStat output should be self explanatory. However, the type of information returned is different between game types. If QStat queries multiple server types, then each server status line is prefixed with its type string. The GAME OPTIONS table lists the available type strings.
The 'l' (ell) sort key displays servers in the order they were provided to qstat. For example, the order in which they are listed on the command-line or in a file. The 'l' sort key cannot be combined with other server sort keys, but it can be be combined with player sort keys. If the 'l' sort key is used with other sort keys, then the 'l' sort key is ignored.
Servers queried using the "Gamespy style" protocol use the same raw output format as Unreal servers.
The response time is a measure of the expected playability of the server. The first number is the server's average time in milli-seconds to respond to a request packet from QStat. The second number is the total number of retries required to fetch the displayed information. More retries will cause the average response time to be higher. The response time will be more accurate if more requests are made to the server. For POQS, a request is made for each server rule and line of player information. So setting the -P and -R options will result in a more accurate response time. Quake and Hexen II are POQS. For most other game servers, QStat makes just one request to retrieve all the server status information, including server rules and player status. The -P and -R options do not increase the number of requests to the server. Half-Life supports three different requests for information; general status, players, and server rules. Each requires a separate request packet, so a total of three are used to retrieve player and rules.
Quake supports a number of control codes for special effects in player names. QStat normalizes the codes into the ASCII character set before display. The graphic codes are not translated except the orange brackets (hex 90, 10, 91, and 11) which are converted to '[' and ']'. Use the hex-player-names option -hpn to see the complete player name.
POQS do not return version information. But some small amount of info can be gathered from the server rules. The noexit rule did not appear until version 1.01. The Quake II server rules include a "version" key that contains the id build number. Recent releases of QuakeWorld have a "*version" key in the server rules. Unreal servers include a "gamever" key in the server rules that contains the server version without the decimal point. Most other game servers include some kind of version info in the server rules.
The following is an example address file that queries a QuakeWorld master, several Hexen II servers, some POQS, and a few Quake II servers.
QWM 192.246.40.12:27004 H2S 207.120.210.4 H2S 204.145.225.124 H2S 207.224.190.21 H2S 165.166.140.154 H2S 203.25.60.3 QS 207.25.198.110 QS 206.154.207.104 QS 205.246.42.31 QS 128.164.136.171 Q2S sm.iquest.net Q2S 209.39.134.5 Q2S 209.39.134.3
If the above text were in a file called QSERVER.TXT,
then the servers could be queried by running:
qstat -f QSERVER.TXT
QStat sends packets to each host and waits for return packets. After some interval, another packet is sent to each host which has not yet responded. This is done several times before the host is considered non-responsive. QStat can wait for responses from up to 20 hosts at a time. For host lists longer than that, QStat checks more hosts as results are determined.
The following applies only applies to POQS. If QStat exceeds the maximum number of retries when fetching server information, it will give up and try to move on to the next information. This means that some rules or player info may occasionally not appear. Player info may also be missing if a player drops out between getting the general server info and requesting the player info. If QStat times out on one rule request, no further rules can be fetched. This is a side-effect of the Quake protocol design.
The number of available file descriptors limits the number of simultaneous servers that can be checked. QStat reuses file descriptors so it can never run out. The macro MAXFD in qstat.c determines how many file descriptors will be simultaneously opened. Raise or lower this value as needed. The default is 20 file descriptors.
Operating systems which translate ICMP Bad Port (ICMP_PORT_UNREACHABLE) into a ECONNREFUSED will display some hosts as DOWN. These hosts are up and connected to the network, but there is no program on the port. Solaris 2.5 and Irix 5.3 correctly support ICMP_PORT_UNREACHABLE, but Solaris 2.4 does not. See page 442 of "Unix Network Programming" by Richard Stevens for a description of this ICMP behavior.
Operating systems without correct ICMP behavior will just report hosts without Quake servers as non-responsive. Windows NT and Windows 95 don't seem to support this ICMP.
For hosts with multiple IP addresses, QStat will only send packets to the first address returned from the name service.
QStat supports Unreal version 2.15 or greater.
UNIX - QStat has been compiled and tested on Solaris 2.x, Irix 5.3/6.2/6.3/6.4, FreeBSD 2.2/3.0, BSDi, HP-UX 10.20/11.0, and various flavors of Linux.
WINDOWS - The Windows version of QStat (win32/qstat.exe) runs on Windows 95 and Windows NT as a console application. On Windows 95 and NT 4.0, short-cuts can be used to set the arguments to qstat. On Windows NT 3.51, use a batch file.
OS/2 - An OS/2 binary is no longer included. Try contacting Per Hammer for an OS/2 Warp binary. per@mindbend.demon.co.uk.
VMS - The source includes a VMS patch from John Ross Hunt. This patch was tested on QStat 2.0b, but has not been tested on the current version. See COMPILE.txt for instructions.
This is QStat version 2.4c.

QStat output templates provide greater control of the appearance of server status information. The results of a server query can be organized, formatted, and wrapped within any other text. The most obvious use is to generate HTML for web pages. However, it could also generate custom output for redisplay within another tool.
There are four output templates:
| Template | Option | |
|---|---|---|
| server | -Ts | Output once for each server queried. (required) |
| player | -Tp | Output once for each player. Must be used with -P. Invoked by the $PLAYERTEMPLATE variable. |
| header | -Th | Output once before any servers are queried. |
| trailer | -Tt | Output once after all servers are queried. |
The server template must be specified to enable template output. The other templates are optional.
Each output template is a file containing text and QStat variables. The text is output unchanged by QStat, but the variables are processed and replaced by QStat. Most variables are replaced by values from a queried server. Some variables have hardcoded values, and some generate no output, but affect how the template is processed.
Variables are grouped according to the templates where they can be used. General variables may be used in any of the templates. Server variables may be used in the server or player templates. Player variables may be used in the player template. Expression variables may only be used with the $IF and $IFNOT variables. If a variable is used where it doesn't make sense, it is ignored and generates no output.
Variables are specified using one of several syntaxes:
$VAR
$VAR:OPTION
$(VAR)
$(VAR:OPTION)
$(VAR:OPTION(ARGUMENT))
The syntax used does not affect the output. However using the $()
syntax is somewhat more readable when the text gets cluttered. If you
want the variable to be followed immediately by text, then the $()
syntax must be used.
| $QSTATURL | Output the web address of the QStat home page. | ||||||||||||||||||||
| $QSTATVERSION | Output the version of QStat being run. | ||||||||||||||||||||
| $QSTATAUTHOR | Output the name of the QStat programmer. | ||||||||||||||||||||
| $QSTATAUTHOREMAIL | Output the email address of the QStat programmer. | ||||||||||||||||||||
| $HTML | Enable HTML friendly string output. Server
results may
include characters that have special meaning in HTML. These are replaced
by equivalent SGML entities. QStat converts '<', '>',
and '&' to '<', '>', and
'&'. Use this variable once in the header template.
| $IF | Conditional output. If the variable option is "true,"
the template is output up to a matching $ENDIF variable. If the variable
option is "false," the template is ignored until after a matching
$ENDIF. See Conditional Options for a list of supported conditional
options.
| $IFNOT | Conditional output. Same as $IF, but the opposite
sense.
| $ENDIF | End conditional output. There must be one $ENDIF for
each $IF and $IFNOT within a template.
| $NOW | Output the current local time.
| $TOTALSERVERS | The total number of servers to be queried.
| $TOTALUP | The number of servers up and running.
| $TOTALNOTUP | The number of servers either DOWN or TIMEOUT.
| $TOTALPLAYERS | The number of players found on all servers.
| $\ | Ignore the next newline.
Not really a variable, but a way to curtail the output of extra newlines.
Saves space in the output while the template remains readable. Must be
the last thing on the line.
| $DEFAULTTYPE | The full name of the default server type specified
with -default.
| |
| $HOSTNAME | Output the host name of the server if known, otherwise the server address as given to QStat. |
| $SERVERNAME | Output the name of the server. |
| $PING | The time in milli-seconds to get a response from the server. If the server is DOWN or TIMEOUT, nothing is output. |
| $PLAYERS | The number of players on the server. |
| $MAXPLAYERS | The maximum number of players allowed on the server. |
| $MAP | The name of the map being played. |
| $GAME | The name of the game being played. This is usually the name of the "mod" run by the server. |
| $RETRIES | The number of retries needed to get the server status. This is a measure of packet loss. |
| $IPADDR | The IP address of the server. Does not include the port number. |
| $PORT | The port the server is running on. |
| $ARG | The server address as given to QStat. |
| $TYPE | Output one of the following depending on the server type:
Quake
Quake II
Quake II Master
QuakeWorld
QuakeWorld Master
Hexen II
HexenWorld
Unreal
Half-Life
Half-Life Master
Sin
Tribes
Tribes Master
Tribes 2
Tribes 2 Master
Shogo: Mobile Armor Division
Quake III: Arena
Quake III Master
BFRIS
Kingpin
Heretic II
Soldier of Fortune
Gamespy Master
Gamespy Protocol
If the server type is not known, nothing is output.

These options maybe used with the $IF and $IFNOT variables. For example, to display player information, the following could be used in the server template:
$(IF:PLAYERS)$(IF:FLAG(-P))
