Example Server Configs

The 2014 and 2021 releases ship a full config set in server-config\ (with ls_query.ini and the gameplay tables), but it was made for a multi-machine service. The 2019 release has none. This page gives a clean example set for one machine, with every server on 127.0.0.1, that works as a starting point for all three. Key names and defaults come from the server code of the 2021 source (checked against 2014 and 2019), and the port layout and values follow an original, unmodified 2021-era config set.

Download

Download all files as a ZIP, unpack it, and copy each server’s .exe into its folder.

Not a complete server yet

The game server also needs the gameplay tables in config\ and clientconfig\, and the DB agent needs a full ls_query.ini. Neither is included in any release. These files get the servers to start and connect to each other; they do not make the game playable on their own.

Tested sets per release

The files on this page are a reference for how the configs work. These sets are the ones actually run on one PC on 2026-11-07, with the database scripts and tools each release needs:

Release	Download	Ports	Servers listen on	Locale	Details
2014	2014.zip	14000 to 14103	the PC’s LAN address	Korea	Run it locally
2019	2019.zip	19xxx	the PC’s LAN address	Indonesia	Run it locally
2021	2021.zip	21xxx	127.0.0.1 with LS_BIND_IP	Korea	Run it locally

Replace every CHANGE_ME, and the example addresses in the 2014 and 2019 sets, with your own values.

Ports used in this example

Server	Port	Used by
ls_mainsvr	40000 (servers), 40001 (GM tool)	game servers
ls_dbagent game	30001	main server
ls_dbagent log DB	30002	main and billing server
ls_dbagent log server	30003	game servers
ls_billingsvr	14011	game servers
ls_gamesvr	14009 (clients), 20001 (servers), 7139 (monitor)	client; relay and login use 20001
ls_relaysvr	55001 (UDP + TCP)	client
ls_loginsvr	40005	client
ls_filewritesvr	14030	client uploads
SQL Server	1433	DB agents

A second game server on the same machine takes the next ports: 14010, 20002 and 7140.

Start order

1. ls_dbagent_game\ls_dbagent.exe -c ls_dbagent.ini
2. ls_dbagent_logdb\ls_dbagent.exe -c ls_dbagent.ini
3. ls_dbagent_logserver\ls_dbagent.exe -c ls_dbagent.ini
4. ls_mainsvr\ls_mainsvr.exe -c ls_mainsvr.ini
5. ls_billingsvr\ls_billingsvr.exe -c ls_billingsvr.ini
6. ls_gamesvr\ls_gamesvr.exe -c ls_gamesvr.ini
7. ls_relaysvr\ls_relaysvr.exe -c ls_relaysvr.ini and ls_loginsvr\ls_loginsvr.exe -c ls_loginsvr.ini

Start every server from its own folder and pass the ini as a plain file name. The -c path is resolved against the folder you start from.

Rules that trip people up

• Comments must start the line. Port=9000 ; game port makes the value 9000 ; game port. Put comments on their own line.
• Section and key names are not case-sensitive, so [DBA_Game] and [DBA_game] are the same.
• The first copy wins. If a key appears twice, the first one is used.
• PrivateIPFirstByte must match your machine. It is the first number of your private IP: 192 for 192.168.x.x, 10 for 10.x.x.x. The servers only start with one or two IPv4 addresses on the machine. With two, the one starting with this number is the private address. Disable extra adapters (VPN, Hyper-V, VirtualBox) if a server refuses to start.
• Defaults differ per server. PrivateIPFirstByte defaults to 0 in most servers, 10 in the billing server and 192 in the relay. Always set it.
• The DB password is encoded. Run ls_dbagent.exe -x yourpassword and put the printed value in PW. A plain-text password does not work.
• Lists end at the first gap. 1=, 2=, 3=… and the server stops reading at the first missing number. The login server list starts at 0, the relay list at 1.
• No spaces in server lists. The login server does not trim name,ip,port, so a space breaks it.

global_define.ini

Shared by all servers, placed in the parent folder of the server folders.

server/global_define.ini

; LosaDev example - shared address book, placed in the PARENT folder of every server folder.
; One machine, everything on 127.0.0.1. Port layout follows the original Korean config.
; Lists are numbered from 1 and end at the first missing key. Values are ip:port.
; Comments must start the line. Text after a value is NOT treated as a comment.

[Main]
1=127.0.0.1:40000

; Optional, IP only (no port). Leave it commented out unless you run a Wemade log server.
;[Wemade_Log]
;1=127.0.0.1

Section	Read by	Notes
[Main]	game server	Main server address. The game server exits if this is wrong.
[DBA_Game]	main server	Game DB agent. Fatal if empty.
[DBA_Log]	main and billing server	Log DB agent. Fatal if empty.
[Log]	main server, passed to game servers	DB agent in log server mode
[Billing]	main server, passed to game servers	Billing server. The game server shuts down if empty.
[Wemade_Log]	main server	Optional. IP only, no port.
[ClassPrice]	main server	LoadTime, default 10
[DBA_AUTH]	billing server	Philippines build only (2019 and 2021)

The game server gets the billing, DB agent and log server addresses from the main server, so it only needs [main].

DB agents

The same ls_dbagent.exe runs three times: once for LosaGame, once for LosaLogData, and once as a log server.

ls_dbagent_game/ls_dbagent.ini

; LosaDev example - DB agent for the game database (LosaGame).
; Start with: ls_dbagent.exe -c ls_dbagent.ini
; PW must be ENCODED. Run "ls_dbagent.exe -x yourpassword" and paste the printed value. Plain text does not work.

[Default]
Port=30001
LogServerPort=0
Log=MLOG

[SQL]
IP=127.0.0.1
Port=1433
Database=LosaGame

ls_dbagent_logdb/ls_dbagent.ini

; LosaDev example - DB agent for the log database (LosaLogData). Listed as [DBA_Log] in global_define.ini.
; Copy ls_config_dba.ini and ls_query.ini from ls_dbagent_game into this folder too.

ls_dbagent_logserver/ls_dbagent.ini

; LosaDev example - the same ls_dbagent.exe in "log server" mode, listed as [Log] in global_define.ini.
; When LogServerPort is not 0, the agent skips SQL completely and listens on LogServerPort instead of Port.
; Copy ls_config_dba.ini from ls_dbagent_game into this folder too.
; Not confirmed yet: whether the original setup used this mode or a separate log server program for [Log].

[Default]
Port=30003
LogServerPort=30003
Log=MLOG3

ls_config_dba.ini (copy into every DB agent folder)

; LosaDev example - DB agent tuning. The same file works for every DB agent folder.
; PrivateIPFirstByte = first number of this machine's private IP (192 for 192.168.x.x, 10 for 10.x.x.x).

ls_query.ini

; LosaDev example - query map for the DB agent.
; The 2014 and 2021 source releases ship the full file in server-config\ls_dbagent\ls_query.ini. Use that one.
; Format: count=N, then 1..N = "<procedure> <parameter types>" separated by single spaces.
; Types: INT8 INT16 INT INT32 INT64 FLOAT DATETIME STR. An unknown type stops the agent from starting.
; With count=0 the agent starts, but every query from the game servers will fail.

[QUERY]
count=0

Password in the log

If the DB agent cannot open the database, it writes the decoded password to its log file. Do not share DB agent logs without checking them first.

Main server

ls_mainsvr/ls_mainsvr.ini

; LosaDev example - main server. Start with: ls_mainsvr.exe -c ls_mainsvr.ini
; Port is for the other servers (private IP). ManagerToolPort is for the GM tool.
; Keep the two ports different: on a machine with one IP both bind to the same address.

[Default]
Port=40000
ManagerToolPort=40001

In the 2014 source the main server has no [MatchingTime] and no match pools, and CCU_sync_time defaults to 10.

Game server

ls_gamesvr/ls_gamesvr.ini

; LosaDev example - game server. Start with: ls_gamesvr.exe -c ls_gamesvr.ini
; CSPORT is the port the CLIENT connects to (TCP and UDP). SSPORT is for the relay and login servers.
; ClientMoveIP: leave empty on a LAN. Behind NAT, set it to the address players use.
; For a second game server on the same machine use the next ports (14010 / 20002 / 7140).

CSPORT is where the client connects, on both TCP and UDP. SSPORT is what the relay and login servers connect to. MSPORT only opens on 127.0.0.1 when UseMonitoring=1.

[Local] Version=119483910 is the Korean version, which the original config uses for both the game and the billing server.

Billing server

ls_billingsvr/ls_billingsvr.ini

; LosaDev example - billing server. Start with: ls_billingsvr.exe -c ls_billingsvr.ini

Never share these files as they are

Real server folders often contain files you must clean before sharing them with anyone:

• ls_mainsvr\ls_auth.ini: GM tool accounts and their passwords.
• ls_billingsvr\ls_config_billingsvr.ini: publisher API keys and client secrets.
• Every ls_dbagent ini: the SQL login and its (encoded, but reversible) password.

Not confirmed yet

• Whether [Log] pointed at a DB agent in log server mode or at a separate log server program in the original setup.
• The [Local] Version values for the other region builds.
• How the servers behave as Windows services instead of -c console mode.

If you get a server running with these files, please share what you had to change.
