This Python script is a command line tool that reads a list of IP:PORT Steam
servers from stdin and outputs information about the servers in a pretty format.
Read more about A2S_INFO and A2S_PLAYER at Valve's Server queries wiki.
To get started, just clone the repository. A list of Left 4 Dead 2 servers is provided in the serverList directory.
Since the script reads from stdin, just redirect your list of IP:PORT like so:
$ ./a2sInfoPlayer.py < serverlist/compList
SirPlease NY #1 | Zonemod v1.9.4 192.223.24.99:27015 25 ms c5m1_waterfront 10
SirPlease NY #3 192.223.24.99:27017 26 ms c2m1_highway 0
Asylum NY T100 #1 | Zonemod v1.9.3 192.223.24.187:27015 28 ms c2m3_coaster 1
[2] Larry's L4D2 Realism 104.153.108.80:27016 31 ms c1m3_mall 0
SirPlease CHI #2 74.91.122.107:27016 31 ms c2m1_highway 0
SirPlease NY #2 | Zone :X: Skeet 192.223.24.99:27016 32 ms c2m2_fairgrounds 1
[...]
The server list file must respect the IP:PORT format, for example:
192.223.24.99:27015
192.223.24.99:27016
192.223.24.99:27017
192.223.24.99:27018
192.223.24.99:27019
192.223.24.99:27020
Any line that doesn't match what an IP:PORT should look like is ignored.
There are many command line options available, here's the help page:
$ ./a2sInfoPlayer.py -h
usage: a2sInfoPlayer.py [-h] [-a] [-e] [-v] [-s] [-n NAME] [-p PLAYER]
[-m MINPLAYER] [-x MAXPLAYER] [-t TIMEOUT] [-r RETRY]
[-c THREADCOUNT] [-o OUTPUTFILESUCCESS]
[-f OUTPUTFILEFAILED] [-w OUTPUTFILESHOW]
[--sort {name,ip,ping,map,player}] [--sortreverse]
[--printestimate]
Make A2S_INFO and A2S_PLAYER requests to steam game servers. The ip:port list
is read from stdin.
optional arguments:
-h, --help show this help message and exit
-a, --active only show active servers
-e, --empty only show empty servers
-v, --verbose verbose information
-s, --showplayers show players
-n NAME, --name NAME search for server name, accepts multiple values
(disjunction)
-p PLAYER, --player PLAYER
search for player, accepts multiple values
(disjunction)
-m MINPLAYER, --minplayer MINPLAYER
minimum player count (inclusive)
-x MAXPLAYER, --maxplayer MAXPLAYER
maximum player count (inclusive)
-t TIMEOUT, --timeout TIMEOUT
timeout before retry (ms)
-r RETRY, --retry RETRY
request retry amount
-c THREADCOUNT, --threadcount THREADCOUNT
max requests at once (MAX_THREAD_COUNT)
-o OUTPUTFILESUCCESS, --outputfilesuccess OUTPUTFILESUCCESS
output destination file for successful connections
-f OUTPUTFILEFAILED, --outputfilefailed OUTPUTFILEFAILED
output destination file for failed connections
-w OUTPUTFILESHOW, --outputfileshow OUTPUTFILESHOW
output destination file for showing connections
--sort {name,ip,ping,map,player}
sort by field
--sortreverse reverse sort
--printestimate prints an execution time estimate
Increasing --threadcount improves performance but can easily overload your network card if the value is too high. You will get more failed connections because of dropped UDP packets. Increasing --retry to 2 (default is 1 try) will increase reliability but also increase execution time and load on the network card. The --timeout option can also be viewed as a maximum ping filter.
Finally, the bash directory contains quick one liner bash commands that I use frequently.
