Do you tried Indy component? I used them in both graphical and console application. It is straight forward.
If you need any sample I will be glad

Yours,
Amir

I Installed on Linux(FC4/5).
I followed the instruction from
http://wiki.lazarus.freepascal.org/index.php/Indy_with_Lazarus. with some changes.

Try it!

Hi all,

I need to developer an application to act as a tcp server that be compatible with windows/linux (debian).

I want to make a command line application (without graphical interface) because my linux server don't have the X installed.

I need of an example of how can I make this.

Does someone have an example of a tcp server to send me?

Regards,

Fabrício

Hi Amir,

I tried, but I couldn't install it on my freepascal/lazarus. Can you help with this installation?

PS: I'm using windows xp

Thanks Amir, I saw this, but I don't have the packets bellow on the Indy 10 installation :(

* Open and compile indysystemlaz.lpk
* Open and compile indycorelaz.lpk
* Open and compile indyprotocolslaz.lpk
* Open, compile and install dclindycorelaz.lpk
* Open, compile and install dclindyprotocolslaz.lpk

How do you do to install without the packets?

Why not Synapse? You must not install Synapse into your Lazarus, because it is just set of units with set of classes and functions. Just include unit in 'uses'...

Sample for simple TCP server is included in demo. (it implementing simple echo)

Latest snapshot of Synapse needs FPC 2.0.4 and it using native Freepascals units for socket communication - you can use it on any linux/unix platform. (and, of course, on Windows platform too)

I believe a simple make in the directory builds the libs+ demoes.

Then run make info as root to check where it installs. (root or not influences the info)

If Ok then run make install as root.

Use Synapse instead of Indy. After I have found Synapse, I dumped Indy.

Lukas has done a very fine tool !!

Cheers, Adrian.

OK,

I downloaded the synapse, but I don't know how to use it to make a TCP server.

I need to do a server that listen on a specific port. After connected the client will send some commands to the server that will make some actions and return the results to the client.

Basicly the client will send strings to the server and receive another strings.

Why synapse? Why indy? You may use fpc unit "sockets" for it. For more information see standard fpc documentation - http://www.freepascal.org/docs-html/rtl/sockets/index.html

Some examples in http://www.freepascal.org/docs-html/rtl/sockets/accept.html , http://www.freepascal.org/docs-html/rtl/sockets/connect.html ... and others.

They are in Lib folder. I myself once tried the synapse but I could not figure it out.
What you want to do is not a hard one, I have written some programs in this style all using Indy.

> Why indy? You may use fpc unit "sockets" for it.

May be because of OOP (at least about Indy).

Check out the echo demo in synapse. It seem to be exactly what you want.

OK I was able to run the echo server example. Now I need to know how can I make a server that gets the commands sends by my client application and make the right actions with these commands.

Can anyone help with this?

PS: I'm trying to install the indy on windows xp without succes, if someone can help me I'll be thanks.

Hello Fabricio,

there are some examples at the synapse wiki page. I suggest that you also subscribe to the - this is the right
place to ask questions about synapse. There are many active users which can answer your questions.

Anyway, if you have the echo server running, than you have "almost" done the job. Instead of echoing the the data back to the client, you have to analyze the commands and send the results back to client.

Cheers,

Adrian.
