Please, FPC for linux is not yet ready for writing servers. I spent many time before came to this conclusion.

I create a unit. It use the ssockets unit. I copied (but another name) from the fcl. I compile it, and want to use, but the program give this output:
something happened
An unhandled exception occurred at 0x080680B9 :
Access violation
0x080680B9
0x0807214C
0x0804847F
0x0804846C
0x00000000

And the unit:

unit Cow_Server;
interface
{$MODE objfpc}
uses
    ssockets;
type
    CowServer=class(TObject)
    private
	CS:TInetServer;
    public
	constructor Create(Port:longint);
	destructor Destroy;override;
	procedure OnConnect(Sender:TObject;Data:TSocketStream);
	procedure Start;
	procedure Stop;
    end;
implementation
    constructor CowServer.Create(Port:longint);
    begin
	CS:=TInetServer.Create(Port);
	;
    end;
    destructor CowServer.Destroy;
    begin
	CS.Free;
    end;
    procedure CowServer.OnConnect(Sender:TObject;Data:TSocketStream);
    begin
	writeln('Connected');
    end;
    procedure CowServer.Start;
    begin
	CS.StartAccepting;
    end;
    procedure CowServer.Stop;
    begin
	CS.StopAccepting;
    end;
end.

I don't know, what is the problem.
PLease Help!
Cow.

It is. We have some apps running here which do a _lot_ of network I/O without problems.

If you wont to write servers, you must use low
level networking functions (libc calls).

FPC for Linux can do these calls !

I'm writing FPC networking programs since 1998
and i have not any problems in this direction !
