How to block logon when client is conecting by razor??

This is just a guess. But I think it would work best, at least I'm pretty sure this is the only way to.

Use an insanely out of date client not supported by razor.

Why do you want to block it anyway?

I search for a way to block some razor options (light level etc)

Light level is handled by the client. Its configurable by sending packets from the server but in the end, its either gonna be blocked or overridden by third party programs. Theres really no way to stop it unless you have a custom client that breaks third party program support. Razor isn't the only thing that handles light level specifically. There are others that modify the client itself to break it.

Seems like RunUO already has support for disabling some Razor features (like filtering the light level). Downside is that every player should use Razor for this to work (*). Check this thread: http://www.runuo.com/forums/custom-script-releases/84092-1-0-2-0-razor-feature-negotiation.html.

I have to say I haven't used, nor tested, that in any ways, so this might not really be what I think it is, and even if it is, you might not be able to use in on POL (for a long time).

* Because POL does not support this AFAIK, if someone could make (script) it to, the razor only requirement could be disabled. If done so, of course, one couldn't force all players to not disable light levels, but only the ones that allow negotiation, so...

So...

Done some runuo script walkthrough and...

RunUo on logon of a player sends a packet to the client:

first four bytes id the head: f00000fe

later there are 8 bytes of feature enabled/disabled

every bit of 8 byte is a feature

so a packet should look like??? f0 00 00 fe 00 00 00 00 00 00 00 02
(to enable only light in razor)

The problem is when I write a simple text command to test:
program razor(kto)

var pakiet := sendpacket(kto,"f00000fe00000000000000ff");

Sendsysmessage(kto,"Pakiet razora: "+pakiet);

endprogram

sending this packet freezes the client...

I`m not so good in programming (since i`m a physic), but somebodu could find this data usefull and help to write something to force the razor to cooperate:)
