Frequently Asked Questions

About Openkore

What is Openkore?

Openkore is an open source bot program, mostly written in perl for Ragnarok Online, created back in 2003. It is licensed under the GNU General Public License GPL.

What functions does Openkore have?

Openkore is capable of doing almost everything a normal player could do on Ragnarok. Its AI permits the use of automatic tasks, like attack, move, use items and skills, storage, buy and sell, open a shop, teleport. You can see a list of currently supported tasks in the Overview page.

Installation and Configuration

Where do I download Openkore?

You can download it on the Links page. Be sure to check the Quick Start Guide if you are new on Openkore.

How do I make it connect in my server?

Currently, Openkore only comes with Official Servers information, so if you want to play on a private server, for example, you will need to get its server's information. See Connectivity Guide.

How do I configure it?

Openkore is based on text configuration files, which are located on control folder. Each file has it's own function and can easily be configured according to your needs. See Manual.

Why is everything in a single line in control/table files?

That's not the problem of our files, but the problem of your text editor. Try another editor.

How can I update it?

There are two ways to update Openkore:

• Using Openkore SVN AutoUpdater - see Updating Openkore Guide (recommended for normal users)
• Using TortoiseSVN - see TortoiseSVN Guide (recommended for testers, supporters, developers users)

Does Openkore work on Linux?

Yes, Linux users have to run Openkore directly in perl. See How to run OpenKore on Linux/Unix.

Connecting Errors

Unknown error code 10060 when connecting to the server

Your server information, set on servers.txt, is wrong. See Connectivity Guide to learn how to get your server's information correctly.

Timeout on Account server, error when connecting to the server

Wrong server information, on servers.txt, or the server has some kind of anti-bot protection againts bots. See Connectivity Guide to check your server's information and Unsupported servers for a list of unbottable servers.

Openkore is showing character information incorrectly

Wrong value for charBlockSize on servers.txt. Possible values are 106, 108 or 112 for servers with Renewal Interface.

Common Problems

My server has some kind of anti-bot, that doesn't let Openkore connect

Unfortunately, Openkore doesn't have any kind of code to break those anti-bots.

OpenKore is showing NPCs and monsters as "unknown"

Wrong serverType, on servers.txt, or outdated recvpackets. See Connectivity Guide to get the correct serverType and Packet Length Extractor to extract the recvpackets.

OpenKore is showing items and skills as "?????"

That's probably your terminal failing to show Korean names which are used with kRO serverType by default. Change your server's settings or use command line arguments to select another table set.

Packet Tokenizer: Unknown switch: xxxx

Packet switch not found in recvpackets.txt, we don't have this packet's length. Recvpackets file needs to be updated for your server. See Packet Length Extractor.

Note: if this switch does not start with a 0 (0123) then a previous packet's length was wrong.

Packet Parser: Unknown switch: xxxx

Packet switch not found in packet_list{switch}, packet switch hasn't been added to the hash.

Packet Parser: Unhandled Packet: xxxx Handler: xxxxxxxxxx

Packet handler not found, there is no function that handles this packet yet.
