login server and domain

[Nemesiz]

Hi,
I was looking some information about domain in server address but I couldn't find. So my question is: does login server report to client the server list with domain name instead of IP?

[UnAfraid]

com.l2jserver.loginserver.network.serverpackets.ServerList.write()

Code: Select all

            writeC(server._ip[0] & 0xff);            writeC(server._ip[1] & 0xff);            writeC(server._ip[2] & 0xff);            writeC(server._ip[3] & 0xff);

Ok. But does l2 client support/understand domain names?

[UnAfraid]

Sadly no you could make login server to resolve the domain before sending it to the client but not to send it as hostname

[Nemesiz]

Sad. But maybe it is possible to send multiple IP address ?

[UnAfraid]

Multiple ips but you must send only one maybe at random.
Are you trying to re-invent Round Robin in l2j?

[Nemesiz]

I`m thinking theoretically. Some of closed source l2j GS have internal and external IP settings and both are send to l2 client. So its very interesting of L2 client limits.

[UnAfraid]

It exists in l2j since years you can use domain but login server will resolve the domain as IP and then will send it to the client.
So its the same..

I already got it about LS and IP. But it can be done by sending all IP address assigned to domain if only L2 client understand this way.

I`m trying to understand internal/external IP settings. As in code:

Code: Select all

 // Server is not GM-OnlyaddServer(client.usesInternalIP() ? gsi.getInternalHost() : gsi.getExternalHost(), gsi.getPort(), gsi.isPvp(), gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), gsi.isShowingBrackets(), gsi.isShowingClock(), gsi.getStatus(), gsi.getId()); 

client.usesInternalIP() ? gsi.getInternalHost() : gsi.getExternalHost()

AS I see if internal is empty external is used. So way I have to set 2 settings then they means the same ? I thought both internal and external IPs are send to client.

[Nemesiz]

Ups. I didn't checked usesInternalIP(). Now i see how its works.
