This does not work as (I) expected. I see the packet arriving in
Wireshark, but on a port I never specified. Port 59395 that is.
Use this:
INetBroadcast.sin_port := htons(1000);

Subject: Re: [twsocket] WSocket.SendTo uses wrong port
Sorry to bother you again.
Can someone please explain to me if there is a bug in the code or if the
problem is located in that grey matter between my ears?
Regards
Stefan
ICS 7.29, RAD Studio 2007
Using this socket:
object LanOut: TWSocket
Addr = '255.255.255.255'
Port = '1000'
Proto = 'udp'
LocalAddr = '0.0.0.0'
LocalPort = '0'
MultiThreaded = False
SendFlags = wsSendNormal
SocksLevel = '5'
SocksAuthentication = socksNoAuthentication
end
I can call:
LanOut.Send(@Buffer[0], aLen);
This works fine, I see the packet arriving in Wireshark on port 1000.
Now trying the same like this:
var INetBroadcast: TSockAddrIn;
INetBroadcast.sin_family := AF_INET;
INetBroadcast.sin_port := 1000;
INetBroadcast.sin_addr.S_addr := INADDR_BROADCAST;
LanOut.SendTo(INetBroadcast, SizeOf(INetBroadcast), @Buffer[0], aLen);
This does not work as (I) expected. I see the packet arriving in
Wireshark, but on a port I never specified. Port 59395 that is.
Is there a fundamental misunderstanding on my side?
Any help welcome.
