TCP / UDP component for laxarus, wich one ?

[pietrobossi]

Hello,

i used to work in Delphi7 with Indy......... to do a very simple program that send and receive UDP broadcast messages on a PC LAN.

I am very interested in porting this software (radio communications simulation) in the linux world, building from scratch. I saw that for lazarus i can select between:

- Indy
- Lnet
- others

The simplest look lnet, but i would like tro try Indy too, but i am confused about my google search......... does it exist a indy version that can be easy installed under lazarus ?

release ?
download from ?
simple examples ?

thanks all gentlemens for your help !

The best one I have found, hands down, is synapse.

Ciao Pietro,

the best I tryed is lnet...

I tryed to install Indy tons of times without success, it's still hard to use inside Lazarus.

Just to take some practice I suggest you to start with lnet or something similar (if you have to use databases use SQLdb).

I don't want to create a new topic, so I ask here.
I tryed lnet for Server (TlTcpComponent and Listen procedure) but it can only receive messages from another lnet client. So if the sender is not and lnet client, i receive nothing, in the OnReceive proceudre with the aSock.GetMessage(s), s will be empty. If there is a solution or a better visual component which has OnReceive etc. procedures I would like to know about that. Thx

I get these errors before I can read anything

Shutdown error: [107] Transport endpoint is not connected

Receive Error: [104] Connection reset by peer

What client do you use on the other side? These errors mean that the connection got closed uncleanly by them...

It's always different, what I want to write is a hublist server, and there are a lot of hubsoft with different client sockets. But I already wrote a hublist server for windows with delphi, on that program I used TServerSocket and everything worked well, but in lazarus there isn't a built-in socket server like that

Why don't you try Synapse? http://synapse.ararat.cz

Because it's not a visual component, and as I said it hasn't got an Onreceive method, and to use it I have to create new threads for that( like in the echoserver demo ). So it's a bit complicated, and I hope there is an easiest way too.
