[twsocket] UDP broadcast error Permission denied
Hi, When I try a SendTo() address 255.255.255.255 with an UDP listening TWSocket I get error WSAEACCES Permission denied, is this normal?. SendTo() 192.168.1.255 works, Firewall is turned off. procedure TMyServer.UdpListen; begin if FUDP = nil then FUDP := TWSocket.Create(nil); FUDP.Proto := 'udp'; FUDP.Addr := '0.0.0.0'; // listening on one interface doesn't change it. FUDP.Port := '30003'; FUDP.OnDataAvailable := UdpDataAvailable; FUDP.ReuseAddr := TRUE; FUDP.Listen; end; procedure TMyServer.SendHelo; var Dst: TSockAddrIn; DstLen : Integer; Buf: AnsiString; begin FillChar(Dst, SizeOf(Dst), 0); Dst.sin_family := AF_INET; Dst.sin_port:= WSocket_htons(StrToIntDef(FPort, 30003)); Dst.sin_addr.S_addr := u_long(INADDR_BROADCAST); Buf := 'Helo'; if FUDP.SendTo(Dst, DstLen, PAnsiChar(Buf), Length(Buf) + 1) = -1 then raise Exception.Create(WSocketErrorDesc(WSocket_WSAGetLastError)); end; -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] UDP broadcast error Permission denied
To broadcast on 255.25.255.255, use connect() and then send(). Connect() will set SO_BROADCAST option at the socket level. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be - Original Message - From: Arno Garrels arno.garr...@gmx.de To: twsocket@elists.org Sent: Thursday, December 23, 2010 12:20 PM Subject: [twsocket] UDP broadcast error Permission denied Hi, When I try a SendTo() address 255.255.255.255 with an UDP listening TWSocket I get error WSAEACCES Permission denied, is this normal?.

Thanks, I have to use the listening socket in order to avoid Bind errors, setting SO_BROADCAST after Listen actually works fine.

Re: [twsocket] HttpCli / Async in thread problems
Forgot to say that the logged status after the call is almost always
HttpDnsLookup
and that the exact line in HttpRequestDone is
If (Sender as ThttpCli).State in [httpReady,httpAborting,httpClosing]
then
Begin
PostMessage((Sender as THttpCli).CtrlSocket.Handle, WM_QUIT, 0, 0);

Subject: [twsocket] HttpCli / Async in thread problems
I have this code
HttpClient.OnRequestDone := HttpRequestDone;
HttpClient.OnCommand := HttpClientCommand;
HttpClient.OnLocationChange := HttpClientRelocate;
httpclient.GetASync;
httpclient.CtrlSocket.MessageLoop
in HttpRequestDone i have the following code
PostMessage((Sender as THttpCli).CtrlSocket.Handle, WM_QUIT, 0, 0);
///
Sometimes when I check the status after the GetAsync with this code
if HttpClient.State httpready
then LogEvent('Execute','After
MakeTheCall',StateToStr(HttpClient.State),HttpClient.Url);
I find several entries in the log event, but I have trouble understanding.
Can someone give me a hint
As far as I can find the problems begin when the call gets a 302 and in
this case the 302 will relocate from www. to www2.xxx
Tested both in V6 and V7
Frans

Found an error in OverbyeIcsHttpProt, not the reason for the error above
line 1760 :
DebugLog(loProtSpecDump, Format('PrepareNTLMAuth end, FStatusCode = %d ' +
should be
DebugLog(loProtSpecDump, Format('PrepareNTLMAuth Begin, FStatusCode = %d ' +
seems like a copy past errror.
seems that the bug is also somewhere related to the NTLM code or call
because the icslogger shows the following
- Starting relocation process
- state = httpReady
- PrepareNTLM
- PrepareNTLM
- RequestDone psss why is that there?? It
will trigger the onRequestDone but at the same time the relocation is still
going on because this is the rest of the ics log while I also get the trace
from my own software due to the trigger.
- Login www2.xxx
- State = httpDnsLookup
