[ANet] Using a hostname to connect to - 10/08/10 23:57

Hi all,

I've tried to use a hostname like "mypc.no-ip.com" to connect to my anet server. When using the IP that is behind that adress, it connects fine.
When I try to use the hostname acknex freezes instantly and crashes with the following info (in german):

Code:

Is there a way to use PRAGMA_API to resolve the host to an IP i can then connect to? I've never worked with the windows API. Any chance to get this included directly into ANet?

Thanks,

Hmmm... I'm not sure about that. I guess you would have to use DNS to resolve the hostname into an IP. But I don't know how difficult this would be to implement.

I think this would be a useful feature. I will take a look into that.

I just tried it with my public server and it works fine. Are you sure that it's not caused by your code?

I used this testapplication:

Code:

#include <acknex.h>
#include "anet.h"
#include "default.c"

void main()
{
	level_load("");
	wait(3);
	
	enet_init();
	
	while(1)
	{
		if(key_1)
		{
			enet_init_server(2300,4,"");
			while(key_1) wait(1);
		}
		if(key_2)
		{
			enet_init_client("mail.aauer.com",2300,"");
			while(key_2) wait(1);
		}
		wait(1);
	}
}

I used [F11] to open the debug panel and checked if I get a ClientID. Even if ANet can't resolve the name, it shouldn't crash but throw a disconnected event.

Please test this out. It's possible that this is a bug of ANet.

I can also confirm that Enet (and thus also Anet) is able to handle hostnames instead of just IP addresses.

Dark_samurai, I've used your testapplication and it still crashes to client on connection, just a second after i'm trying to connect. There seems to be no timeout or similar.

I only changed the adress to connect to. Mine is a bit longer, its 20 characters long, could that be of any problem? I'm using no-ip.com and it works for other games and stuff.

I'm using 3DGS 7.86.2 and ANet 1.3.2.0.

Thanks for the report!

Yes you're right. Because an IP can't be longer than 15 signs, the string was limited to 15 signs. I removed this limit. Now it should work. I've sent you a beta version. Please try it out and tell me if it's working now.

Thanks for the fast fix, it works now.
There is a new bug in the password system now, I've send you an email about it.

The password bug is also fixed now.

I think I will release the current beta version after another few days of beta testing.

Ah, maybe this is the bug I just sent you an email about? If it's already fixed - great! Would you be able to send me the new version? We want to distribute a demo of the game tomorrow and I'd not like to have to disable the password system...
