@jaclas this is actually covered in Indy's installation notes. And no, the REST library does not use Indy, but DataSnap and LiveTiles do
Backing up a little.. Using a binding that's added at design time seems to be different to what I'm doing at runtime:
var
LBinding: TIdSocketHandle;
begin
IdIPMCastClient1.IPVersion := TIdIPVersion.Id_IPv6;
IdIPMCastClient1.DefaultPort := 6000;
IdIPMCastClient1.MulticastGroup := 'FF02::1';
IdIPMCastClient1.Bindings.Clear;
LBinding := IdIPMCastClient1.Bindings.Add;
LBinding.IPVersion := IdIPMCastClient1.IPVersion;
LBinding.IP := '::';
LBinding.Port := IdIPMCastClient1.DefaultPort;
IdIPMCastClient1.Active := True;
end;
When there are no connections to an IPv6 network, it crashes on the setSockOpt call (called from TIdStackVCLPosix.SetSocketOption) when AddMulticastMembership is called. If I use the bindings editor to do the same thing (at least I hope it's the same), it does not crash
I'm guessing I'm doing something in the wrong order

Dont get me started on JS.. .one fo the worst designed langauges ever.. decades behind others yet they think its cutting edge...... they get a new fewature in ES2015 other langs have had for 20 years and they all crow like they are the most advanced thing out there.... but until they get a feature all they do is downplay it....
My personal goal is to use as little of it as possible.. meanwhile I do some Angular development for my main client :-(
...where they put boatloads of business logic into the JS..
@DelphiWorlds the
Bindings property editor is implemented in IdDsnPropEdBindingVCL.pas and IdCoreDsnRegister.pas. And of course, if you are not connected to an IPv6 network when activating the TIdIPMCastClient, you are going to run into errors trying to join an IPv6 multicast group. Populating the Bindings doesn't allocate any socket at design-time, and activating the client at runtime can still allocate an IPv6 socket and bind it locally without being connected to an IPv6 network, but joining the group requires communicating with the network, so a network connection is needed.
You can share something with me?, tks.
I would like to develop a backend with Indy to hear and reply information using a ISO and a front end in IW to see this information formatted.
@JNPSoftware ok, so what's stopping you? What are you stuck on exactly?
I've read that I could use "TClientSocket" for this, but I find it weak
@rlebeau It's a good idea develop a server to receive and a client to response this messages or do all in one place?
but you said you wanted an IW frontend, but IW is web-based so its also a backend, too. Unless you mean you want IW communicating with yet another backend, then it would make sense to use Indy for communications between IW and that other backend, in which case you would likely have IW act as a server for the web browser and a client for the other backend
@rlebeau, i'm sorry, i'm confusing things. I would like to develop separated parts. IW is accessing a database with information of cards numbers, value, transactions list, etc.
Indy server receive/write ISO messages and use a same database of IW. But they are totally separated.

I'm will act like a bank for authorizing a card transaction. I will receive ISO messages from another systems. this is my problem, how can i create a server to receive these messages, and response then in a ISO format.
Since EMBT forums are funky/down again.. .we have put some Delphi as well as Indy forums up to test.. join in!
@JNPSoftware well, the ISO 8583 protocol is fairly straight forward (see https://www.codeproject.com/Articles/100084/Introduction-to-ISO), so what is not clear about it to you exactly? Do you even know how to use Indy in general? Let's start with that.
