Re: [twsocket] Sending video data via UDP

2005-05-07 Thread Francois PIETTE 
  The UdpSend/Lstn demo generates an error here (ListenBackLog Property
does
  not exist), but I can read all the source.

It is likely you have an old wsocket.pas or wsocket.dcu somewhere. Check you
installation and be sure to delete every old file version. Use the latest
version from my website.

  The question is, I suppose to use TWSocket.Send(buf,size) ok? Will the
udp
  stack take control over the 20Kb I am trying to send? How do I control
  that

You must set TWSocket.BufSize to the largest packet you want to send. By
default, it is 1460 bytes which is the largest TCP packet on Ethernet.

Note that WinSock may fragment you packets depending on the hardware layer.
You have no control about it. It may also limit the maximum packet size to
some limit depending on the implementation. Also no control about that.

 Other question is, there is the SendTo(Addr,buf,size) method, maybe I
should
 use that, but is there any easy function to convert the normal dotted IP
 address (127.0.0.1, ie) to the 'sockaddr_in' type?

Use WSocket_inet_addr function (not a method of the component, a simple
function).
Something like:
var
DestAddr : TSockAddr;
begin
FillChar(DestAddr, SizeOf(DestAddr), 0);
DestAddr.sin_family  := AF_INET;
DestAddr.sin_addr.S_addr := WSocket_inet_addr('192.168.1.1');
WSocket1.SendTo(DestAddr, SizeOf(DestAddr), Data, DataSize);
end;

 Hello,

 I made some authentication test with the THttpCli component. I use
 Ethereal to see what the component send and receive. With my big
 surprise, when the component made an authentication using NTLM,
 Ethereal show me the credential as clear text!!!
 At this point the question is: the NTLM is secure as Basic?

There is something wrong in your test.

Not in my test but in my eyes. WHat will be showed are user and host
name :-)
Sorry for false allarm...

[...]

 P.S. A little question to the Ethereal users. Someone know if it is
 possible to monitoring the local tcp traffic?

You mean loopback capture on local interfaces?

Exactly.

I think this is not possibile due to a limitation of Windows IP stack.

:-(


Bye, Maurizio.
