Operation Flashpoint:Dedicated Server
This article covers some of the aspects of the dedicated server for Operation Flashpoint. Please feel free to update this article with any related information.
"OFPR_Server.exe -config=server.cfg -netlog -nomap -port=2302 -mod=hisky"
-config= <---- Specifies the config file to use. See Operation Flashpoint: Server Config File -mod= <---- Extra command to run folder mods -nomap <---- Command to run default addons and only run extra addons when mission is Exe -netlog <---- Command to Record IP address to find id changers and cheaters -restart <---- Restarts the server if it is crashed/shutdown -port= <---- Port for the server to listen on. -dplay <---- In OFP this specifies Direct Play networking option
Performance Tuning Options
There are also some parameters that can be used to fine-tune network performance. You can add the following entries to the Flashpoint.cfg / ColdWarAssault.cfg (the main Flashpoint configuration file)
|MaxMsgSend||128||Maximum number of messages that can be sent in one simulation cycle. Increasing this value can decrease lag on high upload bandwidth servers.|
|MaxSizeGuaranteed||512||Maximum size of guaranteed packet in bytes (without headers). Small messages are packed to larger frames. Guaranteed messages are used for non-repetitive events like shooting.|
|MaxSizeNonguaranteed||256||Maximum size of non-guaranteed packet in bytes (without headers). Non-guaranteed messages are used for repetitive updates like soldier or vehicle position. Increasing this value may improve bandwidth requirement, but it may increase lag.|
|MinBandwidth||131072||Bandwidth the server is guaranteed to have (in bps). This value helps server to estimate bandwidth available. Increasing it to too optimistic values can increase lag and CPU load, as too many messages will be sent but discarded.|
|MaxBandwidth||2147483647||Bandwidth the server is guaranteed to never have. This value helps server to estimate bandwidth available.|
|MinErrorToSend||0.01||Minimal error to send updates across network. Using smaller values can make units observed by binoculars or sniper rifle to move smoother.|
|MaxCustomFileSize||131072||Users with custom face or custom sound larger than this size are kicked when trying to connect. Although the default is 128 KB the game will ignore faces larger than 100 KB and sounds larger than 50 KB.|
The greatest level of optimization can be achieved by setting the MaxMsgSend and MinBandwidth parameters. For a server with 1024kbps we recommend the following values:
MaxMsgSend = 256; MinBandwidth = 768000;
To install and use the dedicated server on Linux, you'll need the following:
- Game data from a Windows installation of OFP.
- The server executable installer archive (dead link)
- The gunzip compression program from the gzip package.
- The gcc C compiler package.
- The "uudecode" program from the sharutils package.
Getting the game data
In order to run a dedicated linux server, you won't need all the OFP files that are installed on your Windows machine. Community member Kegetys has made a useful script that will create an archive with just the files you need. Visit his OFP page and download and use the Linuxarch10.zip script to create a minimal set of files needed. Then, upload the resulting archive to your server.
There's a post on the BI forums describing the installation: Linux server setup howto (dead link)
