Re: [twsocket] TWSocket and data packet length
Hello, Packet fragmentation is something you may not fully control whenever you trick MTU size on both client and server side as many devices in between may also fragment your packets. For example a firewall with different MTU size set on its Ethernet interfaces. I regularly have such problem (I work for an French ISP). regards. FS Thanks for your help... FS I found why it didn't work anymore, the device was connected on a 10Mb Hub, and at the beginning I made the tests with the device connected on a 100Mb switch. FS This makes a huge difference ! FS This explains why it worked at a time and didn't work for the last days... FS The real problem is that the device is too sensible to packet fragmentation and anyway we cannot assume we can always have the best MTU size ! FS I will try to get the device behavior modified (not sure how many chances I have !!) FS PS: The TCPOptimizer seems an interesting tool ! FS Thanks again !

FS Usually the packet size (called MTU) has a 1500 byte default size. FS If you try to send a 2500 byte packet then this packet will probably be fragmented into 2 packets as you wireshark dump showed. FS I recommend you to use TCPOptimizer from http://www.speedguide.net/downloads.php FS This tool will show your actual System level TCP settings and MTU size and eventually change it. Default should be 1500 but you may increase this size but think that this may have some side FS effects especially if the machine also need to communicate over Internet as packet fragmentation may not be managed very well (web page don't show up, FS POP3 may not receive full mail...). FS TCP Optimizer also have a function to test largest packet you can send to destination (MTU/Latency tab and then Largest MTU button). FS You may also manually do this test by sending non-fragmented pings with forced size to detect if your destination can fully receive big FS packet. FS example : ping -4 -f -l 1472 192.168.0.1 FS This will do a ping to IP 192.168.0.1 with 1472 packet size (1500 - 16 of ethernet encapsulation) and -f say no packet fragmentation allowed. This basic test should work but you may set FS bigger packet (try the packet size you need +16). FS regards. FS Thanks François for your help ! FS I will try this tomorrow... Just to be sure I'm not asking in the FS wrong direction, this already worked with my program a few weeks FS ago... And now without changing anything (or nothing consciously FS at least !) it doesn't work anymore.

Re: [twsocket] TWSocket closing after every transaction with external HTTP server
Hello, How do you now socket has been closed ? have you done some tcpdump compare between wroking and non-working system ? May be some users are going out thru a proxy that remove the keep-alive ? regards. r Hello, r I have a Delphi 6 application that talks to an external device that acts as an HTTP server. I am using the ICS TWSocket components for this application. I open up a socket to talk to the device r and handle the necessary header and body crafting to talk to the server. In other words, I am not using the ICS HTTP client component but using the lower level TWSocket component and handling the r necessary HTTP handshaking myself. r The headers I craft and send to the external device have the keep-alive flag set to TRUE. On my system, after I send anything to the external device, the connection will stay open continuously and r will not close until approximately 30 seconds of inactivity occurs (30 seconds where I don't make any requests of the external device as an HTTP server). I don't know if the external device closes r it or if Microsoft Windows does it. But the important point is that normally I can do multiple sends and the connection will stay open until I send nothing for about 30 seconds. This works fine r and is what my code expects. r However, on some of my users systems the socket is closing after every send. I do have code that checks for a closed socket and attempts a reconnect to the external device if necessary, but does r not expect to have to do a reconnect with each transaction. r My questions are: r Is there a system setting for sockets that might be causing this anomalous behavior on some users systems? r If so, are there Windows API function calls I can use to query the offending parameter and then set it to the expected close on 30 seconds of inactivity instead of with each transaction? r If so, can I, or how do I do it in a manner that will not adversely affect any other programs running on the users system? r Thanks, r Robert r -- r To unsubscribe or change your settings for TWSocket mailing list r please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket r Visit our website at http://www.overbyte.be -- 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

TB When I use the software supplied with my TEMPerLAN, I now see what I TB take to be the outbound transaction, the Command BB 83 from my PC TB to the TEMPerLAN. More in a moment. I've always been able to see the TB part where the TEMPerLAN sends back the data. TB I'm not sure how I am supposed to tell which way stuff is flowing TB when I look at the SmartSniff screen... other than knowing by common TB sense, when, as now, I know what's in the messages. TB Is my guess at what is going on reasonable? TB It seems that the software in my PC generates a thing that it sends TB to the TEMPerLAN, well, to whatever is at the IP address I've given TB it, which, as it happens, is where the TEMPerLAN it. TB That thing then triggers the TEMPerLAN to do the same, but in TB reverse, and sending back to the IP address which came with the TB message from the PC. TB (I'm pretty sure that the TEMPerLAN, for this, is not using UDP. I TB even have an idea that I know what UDP is, you'll be glad to know!) TB A better statement, with proper terms, of what (may) be going on TB would be welcomed. TB SmartSniff has two lines now, as I said.

Re: [twsocket] ICSV6 package _InToStr unknown procedure
Hello, AG Anyway, since you use Delphi 7 why don't you work with ICS v7, AG v7 is better than v6. Good question :-) ICS V6 was the last one I used and since I have not seen any comparison sheet between v6v7 I never took the time to test it.

Re: [twsocket] ICS V5 and V6 installed at the same time ?
Hi, Instead of running Delphi on vitualized machine you can also start it from a Virtualized version you create with ThinApp (from VMWare) that is different from full machine virtualization as it will only virtualize a specific application instaed of full machine into a stand-alone big single EXE file you can start instantly on any machine without installation, only copy/run EXE file ! So you could create different virtualized Delphi environment. You could also virtualize your own delphi app so no need to make installers. regards. -- 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
[twsocket] [OT] Delphi virus
Hi, I suppose some of you have been informed about a virus spreading aver Delphi 3-7 installed machines. I've been infected myself on my 3 Delphi 7 machines ! The virus itself is not dangerous (glad) and only spread if your machine is installed with Delphi 3-7, then it change code of sysconst.pas, rename old .dcu to .bak, recompile it, and put .pas back to original, so once infected your Delphi machine each time you compile a new EXE then virus is inside it and once executed on an other machine it search for possible Delphi 3-7 installation to spread using same scheme. Look like tons of Delphi apps you can download around Internet are already infected, so the virus may exis for some months but has only been discovered last week. Virus do not hurt anything on system, only try to spread on Delphi installed machines but for now any up-to-date anti-virus with trigger an alarm so your customers may be estonished. regards. -- 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] Using lots of TSmtpCli in a single application

Also if a MX refuse you because of some blacklist then remove thoses mails from the queue and send you a mail alert so you can investigate why destination refused your mail. ARMSL It's important not to fail an email on a first refusal, due to the wide ARMSL usage of 'greylisting' where the SMTP server rejects the first email ARMSL attempt and then allows a second attempt, typically 10 to 15 minutes ARMSL later.

Re: [twsocket] Using lots of TSmtpCli in a single application
Hello Angus, You are true, I made a mistake talking about multiple threads, I meant multiple components in a single thread with a thread dedicated to the smtp component's so it is separated from the main GUI thread so the visual interface (if any) should be always responsive whenever the smtp thread is working hard. regards. The application I'm working on is 9 years old, has many thousands of man hours spent on it, and whilst it would be nice to have a single TSmtpCli, in order to avoid a massive code rewrite it's much easier for me to have lots of TSnmpCli components, rather than one (you can't see it, but I can of course). ARMSL The issue we were discussing was not the use of a single TSmtpCli which ARMSL is clearly unsuitable for all but the most simple mail servers, but ARMSL whether you should be using threads with multiple TSmtpCli components (or ARMSL most other ICS components for that matter). ARMSL I have an application that captures data on 400 TWSockets simultaneously, ARMSL in a single thread. ARMSL As was said, two or more threads are beneficial where there are multiple ARMSL processors available to the application and you can hog the entire server, ARMSL or where you really are handling thousands of simultaneous connections.

Re: [twsocket] Using lots of TSmtpCli in a single application
Hello Pete, 200 mails per hour is really not much, a single thread can do much more. But you may be slowed by the other side smtp server if it is slow or timeout. So doing multi-thread is a good way to maintain a good average speed. You can create 20 threads with a common queue that each thread can take mails from, so if a thread is slowed because of slow or timed-out smtp server, then the other threads continue to empty the queue and send e-mails to other smtp servers. In case you send multiple mails so same MX domain, then make some function that will re-arrange the queue to move slow or timed-out domains to the end of the queue so you'll retry them later. Also if a MX refuse you because of some blacklist then remove thoses mails from the queue and send you a mail alert so you can investigate why destination refused your mail. regards. PW Hi PW I've used ICS components for a while now and had great results. PW I have something new to do and wanted some advice before starting a new project. PW Previously my app used a single TSmtpCli and this all worked fine. Now however I have to send mail on behalf of lots of accounts and the number of TsmtpCli components in use simultaneously, used PW in a multi threaded application, could be in excess of 100. PW Assuming that the machine has enough memory and processor power, am I likely to run into any problems? PW I don't evisage the email volumes being massive - say 20 per hour per account, meaning something like 200 per hour outgoing per application. PW My reason for asking is simple - I'm doing something unusual. If it is likely to be a problem I can try concentrating all emails through a single Tsmtpcli but because of the code base I am PW working with this will be much harder to do. PW Any comments welcome.

Re: [twsocket] Async in 1GBit LAN, high CPU?
Hello Arno, 1GB networks are very difficult to tune as many hardware behind the network cards can't handle such high speed, for example hard drives on client machines usually can't handle full 1Gb speed reception and will stay at average 80-100Mb only this making different bottlenecks on the machine that could go 100% CPU when it should not. Also an other thing, if you force 10Mb or 100Mb on one side you may encouter some problem if other side is set to auto-negotiate as the other side will always try to re-negotiate to higher speed (and them produce a lot of garbage due to negotiation). regards. AG Francois PIETTE wrote: That makes me think we need a throttle at the root (TWSocket). Would be interesting. AG Will think about it. Just switched the roles, installed the mail server on a slow(er) box and ran the TSmtpCli application on the fast(er) one. CPU use of the TSmtpCli application was max 35% whereas the other way around 60%. Try setting the network speed to 10 Mbps (you should be able to set the speed in the hardware config). AG I changed it from Autodetect to 10 MBit/s full duplex. There's now AG just 0-1% CPU use and the connection became incredible slow, much too AG slow, that must have messed up something. AG -- AG Arno Garrels I guess you'll see a dramatic drop in CPU usage because your app will be really network bound.

Hello Arno, I am using Delphi 7 / ICS 6 The SmartCard I am working on is the French Doctor's HealthCare professionnal card.

Re: [twsocket] SSL PEM error
Hello, As I told you I am still learning about thoses Smartcards but it seems that the SmartCards has some functions you can call, I tested one called random number generator, but it also can make authentication key calculation and I suppose this is why the private key cannot not be extracted but only used by the card when you call some of its functions to compute some encryption or crypto key validation. I know the card I use has a signature and a authentication X.509 certificate that I can access, but it do not have a encryption certificate so I cannot use it to do strong Virtual Disk Image encryption, for this i'll need to request the encryption certificate to the authority of the SmartCard constructor.

Re: [twsocket] Windows 7 Beta
Hello Angus, A few hours to install ?!? tired to download the beta from the link provided here earlier, but every time at around 330 MB size I get a broken download. ARMSL I think Microsoft removed the files from the original link I published on ARMSL Saturday, both my attempts stopped mid afternoon. ARMSL There is a new link on the W7 home page to the beta, which provides a ARMSL license key and then downloads from different servers using the Akamai ARMSL downloader (MSIE only, Firefox does nothing). ARMSL The ISO then came down in 30 minutes last night, but took a few hours to ARMSL install.

Re: [twsocket] OT: Beta yet stable secure tunnel client--looking forward to your comments!
Hello, FT Ok I see how you view it. I had read that MS had great plans for Windows FT 2008 as a server OS. How do you guys evaluate it? Do you think Linux TCP/IP FT is superior or is it just people preferring Linux because it's free? Linux is free that's true, but it is also prefered for firewall/ssl/ssh blackbox solutions. FT Also, Dod, you mentioned stunnel being unstable. What other free solutions FT do you have experience with? How do they compare to our ICS-based solution? I have not tested the other solutions from Kiwi or Barracuda. The main problem I have with stunnel is that sometime the connection between client and stunnel goes into timeout and then I must retry multiple times until stunnel accept the conneciton or stop/start stunnel service. I have not yet investigated about this problem and found a workaround by scheduling an stunnel service's stop/start each hour (for POP3 usage it's not a problem). But this is a personnal experience, I am not SSL or stunnel expert at all. regards. -- 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] OT: Beta yet stable secure tunnel client--looking forward to your comments!
Hello Fastream, FT Ok, is there any way to compile ICS/BCB2009 code for Linux? FT I had enabled WSocket::keepalive for the timeout problem! You should add a setting to specify timeout delay. I suggest you to read stunnel help page to see what kind of conf parameters it provide, may be you could implement some of them that can also be usefull (they have multiple kind of TIMEOUT setup for example that may tune up some delay problems). But I explained myself bad about my stunnel problem. The client connect to stunnel but nothing happend until some timeout happend, I don't know who decide to drop the cnx and why stunnel do not proceed, may be because it also get timeout from stunnel-gmail connection side, this is what I must investigate. Talking commercial I think you may provide the client part for free so users can use/discover it in conjuction with any SSL server and then see that you also have a strong Windows SSL server product to sell.

That pattern HS basically results in a virtual ack/nack process, which orders data by HS default. UDP is not only unreliable, it is also inherently UNORDERED. So, HS it is possible that packets could appear out of order, if you were sending HS multi-packet bursts. This requires you to provide for orderly logic as well. HS Hence, the queue of some type.

Re: [twsocket] ICS functions blocked when UI is active
Hello,
I personnaly always create and manage the socket component in a
separated thread. This permit to avoid such problem, and also when the
reverse appear when your socket procedures has a very high activity
that could slow down the main's app message queue that make it less
responsive (or near freezed).
regards.
I have observed that Windows does not pass messages to an application when
FP certain User Interface functions are active. Examples are an open drop-down
FP menu or a user dragging a window. This can cause ICS functions such as this
FP Socket Open code to fail:
{ Use while to repeat connects to ensure enough time for reset to end }
tTarget := Time + ((FiResetTime / 1000.0) / 86400.0);
while not FfConnected and (Time tTarget) do begin
FiLastError := SocketConnect; { Sets FfConnecting }
if FiLastError = FX_OK then
begin
{ FfConnecting is cleared by FWSocketSessionConnected, may happen
FP on
socket connection timeout }
while FfConnecting do
Application.ProcessMessages;{ This can be
FP FWSocket.MessagePump; }
end; {if FiLastError=FX_OK}
end; {while not connected}
With a drop-down menu open, this will run as for long as FiResetTime is
set ( 30 seconds) without connecting.
Is there a way to make Windows continue to pass messages even if a
FP drop-down menu or other UI function is active?
Thanks,
John

I don't understand very well what you mean, but an image in a mail is

To do this you may have to decode attached picture into its orignal

JC Currently I have a program that works 99% OK ;-)
JC I compose a rich text email in
JC BodyText: TJvRichEdit;
JC and I send it with code like this:-
JC if BodyText.PlainText then sl.Text := BodyText.Text
JC else Common.JvRichEditToHtml.ConvertToHtmlStrings(BodyText, sl);
JC where sl is a TStringList.
JC Then (code that was straight out of an example) :-
JC procedure TSMTPMailMsgForm.SmtpClientGetData(Sender: TObject;
JC LineNum: Integer; MsgLine: Pointer; MaxLen: Integer; var More:
JC Boolean);
JC var
JC Len: Integer;
JC begin
JC if LineNum sl.Count then
JC More := FALSE
JC else begin
JC Len := Length(sl.Strings[LineNum - 1]);
JC { Truncate the line if too long (should wrap to next line) }
JC if Len = MaxLen then
JC StrPCopy(MsgLine, Copy(sl.Strings[LineNum - 1], 1, MaxLen - 1))
JC else
JC StrPCopy(MsgLine, sl.Strings[LineNum - 1]);
JC end;
JC end;
JC Now this works and we get nicely formatted emails sent out. EXCEPT when
JC the user puts an Image into the BodyText (TJvRichEdit).
JC In this case the image is simply dropped.
JC I'm hoping that there is a simple solution that doesn't involve
JC rewriting too much !

Re: [twsocket] UDP Newbie...
Hello zayin,
I tried same sample as Wilfried and its OK for me.
Are you sure your port was not in use at the time you tried to start
the program ?
netstat -an will show you all opened/listening port.
if none is listening on your port then you application should
listen.
regards.
Did you try the code that I have posted?
z Yes, copy and paste with:
z ...raised exception ESocketException with message Error 10049 in function
z bind address not available.
z Changing the ip address or port does not change the error. It gives the
z error on the listen.
z Minutes later
z Now after playing with the settings, changing port, ip address etc it works.
z Does not make since.
z Windows firewall did appear for unblocking permission.
z Minutes later
z Now, back to my testing application and changing connect to listen generates
z the same error.
z Going back to connect, all if working again.
z Something I do not understand is going on.
z Ciao,
z Mark

z Hello Mark,
z if you look into source code you see that SendStr call Send, so it is exacly
z the same. I used SendStr just because I was lazy :) I tryed it on a machine
z with an older version of ICS, but it is exacly same result with latest

Re: [twsocket] small but pertinent doubt
Hello João, One more thing, I recommend you to create the TWSocketServer into a separated thread just to avoid your appplication interface to be overloaded/non responsive in case of hudge activity. You can also dettach some client sockets and attach them into some separated thread if they may take longer time to execute (for exemple long database request or disk file activity). As ICS uses an event driven model this permit to manage very easy tons of connections but you must be responsive and make each triggered event finish as fast as possible or the next event (for exemple an other OnDataAvailable for other client) will have to wait. You may also create some worker thread that you can send thoses longer operation the release the event faster. Regards. JG Hello, JG Jus tone more thing: can youn point me to that example?

Re: [twsocket] small but pertinent doubt
Hello João, No, Put only the main TWSockerServer into a separated thread, that's all, this is if your applicationis not a service and has a graphical interface (one or more windows), so even if you have hudge network activity, your buttons/menus in your forms will stay responsive. Making one thread per client is non-sense using asynchronous ICS model. But eventually, you may create some worker thread or temporary thread that will proceed some longer requests without queueing for too long time all other events ICS sockets will receive. Regards. JG OK, let me se if I understood JG The best option is to take the TCpSrv example from ICs, put it on a new JG Thread, and create a new Thread for each client, like the example on the JG MtSrv?

Re: [twsocket] sub: FTPServer Timeout

[twsocket] Listening UDP port and specify same port for UDP sending
Hello,
I have a machine with only one IP address and a listening
WSocketServer on UDP port XXX.
From same project I want to send UDP data to an other machine but with
.LocalPort set with same as current listening server port.
On Win2K, XP and Vista it works well, UDP data is sent with a forced
src port number same as the listening one, but on NT4 (sp6a) it give a
#10048 Addr already in use.
There is an application on this NT4 machine that already work that way
(I have not the sources) Any idea how to do make it work is there
something special to set in socket options ?
I know I already sent a previous message meaning nearly same but I
forgot to tall that an application was already doing it perfectly on
the NT4 machine so there should be a way to do it with ICS.
Thanx for any help.
Here a very small code that can reproduce the problem :
procedure TForm1.Button1Click(Sender: TObject);
begin
// first we make it listen
WSocketServer1.Port:='12345';
WSocketServer1.Proto:='udp';
WSocketServer1.Addr:='127.0.0.1';
WSocketServer1.Listen;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
// then we try to send
WSocket1.LocalPort:='12345';
WSocket1.Port:='12345';
WSocket1.Addr:='127.0.0.1';
WSocket1.Proto:='udp';
WSocket1.Connect;
WSocket1.SendStr('hello world');
WSocket1.Close;
end;
procedure TForm1.WSocketServer1DataAvailable(Sender: TObject; ErrCode:
Word);
begin
// this trigger nciely on 2K/XP/Vista, not NT4
showmessage(TWSocketServer(sender).ReceiveStr);

Re: [twsocket] Problem using same UDP port for both listen and send
Hello Dave, Thanx for this long answer, I am already aware of all the way it should be done, but I have to work on a very old client/server project for which the sources has been lost, so I need to keep the same way it actually works and do the patch thru a proxy that will emulate the original server way of managing it's UDP protocol. Neverless, I found a workaround. Regards. DB Unless you are using an existing known protocol, in which case you'd DB idealy use one of the recognised existing port numbers Port 80, DB 8008, 8080 for an HTTP server for example. DB Letting the system pick a random port to listen on as a server is a bit DB unproductive, as how would you inform any likely clients (not on the DB same machine) what server port to connect to?... DB Best I think to pick a specific port number to start with for the server DB to create and listen on, and then let the clients pick a unused port for DB them to talk with, to connect to your server that is listnening on a DB known port. (UDP is a connectionless protocol of course) DB It is posible to use the same port number to talk and listen on, but not DB generaly on the same physical machine for both a client and server, DB something has to be different between them, either the IP address, or DB port number (or both) Or, the system hasn't a clue as to who what DB where etc... DB I guess you could define another localhost address, 127.0.0.2 for DB example perhaps? AFIK there is no reason why a single machine can't DB have multiple local loopback addresses. Unless someone else knows DB different. Then you could use the same Port number for both client DB and server, with care... DB Check out... DB http://www.iana.org/assignments/port-numbers DB For typical known port numbers, some may be of use, many are worth DB avoiding! (to keep script kiddies away, and to avoid strange connect DB requests)... DB Note, that ports in the range of... DB 49152 through 65535 are avaialable for Private or Dynamic port DB assignments. You can use any of them for anything, and being way up DB there in High Port Land should be well out of the way of any malicious DB port scanners looking for something to play with DB Hope something helps..

Re: [twsocket] TFtpClient, DataSocket.OnSessionClosed event is not always fired.
Hello asvetov, Firewalls and Anti-virus are NEVER 100% disabled because they load low level drivers on system boot. So the only way for you to be sure that firewall is not involved in your problem is to uninstall it or you may reboot Windows in safe mode and temporary rename kl1.sys klf.sys klim5.sys so Kaspersky will not run at all next boot. regards. a once again: firewall is completely deaktivated. Background file scanner too. But seems to be, that some Kaspersky componnents still active and only when I complete deactivate protection works all a fine. a BTW: As for Kaspersky, I really like it and did my BEST experiense with it. a 08.03.08, 20:52, Arno Garrels [EMAIL PROTECTED]: Sounds more like somebody is blocking/intercepting the call to Connect? BTW: I do not use any real time AV scanners or other background security tools, it's my experience that they make more trouble than they help. Same applies to personal firewalls. They all hook the API function calls as they like. If they do not hook correctly the hooked application will fail or even crash. And especially Kaspersky is known to do ugly things in their drivers (as I read in a nice analysis from some driver-guru on the internet a couple of months ago).

[twsocket] Problem using same UDP port for both listen and send
***second sending as the first mail ssems to never reach the mailing list*** Hello, I am working on something like (very old project using applicatons for which I have not the sources): - Create Server UDP socket port 0 (Winsock select the listening port itself) and do .Listen - I retrieve port number using GetSockName/.sin_port - I create a client socket to connect to an other machine but I set LocalPort with same socket number as the one retrieved by server socket - I .Connect the client to other machine and .Send the data, and all is fine, the machine on the other side receive UDP packet and the application now to which port it has to send data back (that is the way it works and I can't change this). All works fine on my XP dev machine but the program must finally run on NT4 and once I try on it,I get WSAEADDRINUSE ( 10048 ) Address already in use. So I tried to understand and it seems it has something to deal with Port usage not Addr really. Now if i set LocalPort to 0 before .Connect then all is fine of course because NT4 will select its own free port for sending. Any idea why NT4 do not accept localport for UDP sending to be set with same number has a listening server port on same machine/ip ? May be an old NT4 Winsock limitation ? I know NT4 is old but I have to work on a very old server that can't be upgraded. May be some of you remember such limitation ?

Re: [twsocket] UDP problem
Hello Skok,
I don't really know what the problem is but I think you do something
too complicated...
A simple .Send to 255.255.255.255 is enought, then OnDataSent do a .Close
why use a TTimer ?
ST I'm trying to create application that would run on multiple machines.
ST This application has to know IP addresses of all other machines running
ST same software.
ST I'm trying to do something like discovery on network. Protocol I decided
ST to use for discovery is UDP. On mailing list I already saw, that only
ST one TWSocket component
ST can be used for receiving and sending data. So, I wrote following code
ST for listening:
ST UDPSocket.Proto :='udp';
ST UDPSocket.Addr :='0.0.0.0';
ST UDPSocket.Port :='1234';
ST UDPSocket.Listen;
ST Timer1.Enabled :=True;
ST and on timer event there is code for sending broadcast data to notofy
ST others about existence:
ST procedure TForm1.Timer1Timer(Sender: TObject);
ST var
ST SendTo:TSockAddrIn;
ST LenSendTo:integer;
ST Data:string;
ST begin
ST LenSendTo:=SizeOf(SendTo);
ST Data:='Test'+#0;
ST SendTo.sin_port :=htons(1234);
ST SendTo.sin_addr :=StrToInAddr('255.255.255.255');
ST SendTo.sin_family :=AF_INET;
ST UDPSocket.SendTo(SendTo,LenSendTo,@Data[1],Length(Data));
ST end;
ST StrToInAddr is function that I found in mailing list.
ST On receive even I have code from udplistener sample:
ST var
ST Buffer : array [0..1023] of char;
ST Len: Integer;
ST Src: TSockAddrIn;
ST SrcLen : Integer;
ST begin
ST SrcLen := SizeOf(Src);
ST Len:= WSocket.ReceiveFrom(@Buffer, SizeOf(Buffer), Src, SrcLen);
ST if Len = 0 then begin
ST Buffer[Len] := #0;
ST listbox1.Items.Add(StrPas(Buffer));
ST end;
ST end;
ST Problem is that sending is ok (no error), but ondataavaliable event
ST never gets fired, so I'm assuming that nothing is sent.
ST What am I doing wrong.
ST P.S. I have been using ICS for awhile now and I think that this is most
ST stable component suite for networking. Keep the good work.
ST Regards,
ST Skok Tone

[twsocket] Error #122 OnSessionConnected (UDP)
Hello, I use ICSv6, and do .Connect using standard TWSocket component server but inside OnSessionConnected the ErrCode is #122 instead of 0. If I don't care about ErrCode code and do .Send inside OnSessionConnected as usual, then UDP buffer seems correctly sent and is received as it should by UDP server.

Re: [twsocket] TCP and fragmentation
Hello Markus, Fragmentation as other guys said is IP issue and you can do nothing about it if any device between sender and receiver's machines cannot bring packet the same size they have been sent from source. IP protocol has come message system to ask for sender to resend packet as fragmented (below and under no control of ICS). But as it is ICMP messages and many firewalls may block it default, then your machine may never receive the fragmentation's request. This also happend when you are using some VPN network and you may have to set MTU size of sender's machine down to 1400 that is a good value. This can be done thru registry or using some tools like DoctorTCP 0.21 (DrTCP) or SG TCP Optimizer 2.0.3 Regards. MH since the device I want to talk to does only support sending back the MH UDP answerts to a predefined IP thus requiring a fixed IP adress on PC MH side I have to experiment with TCP now. MH I originally used UDP because it's fragmentation free because behind the MH device I'm talking to sits another one which actually gets the data I MH send but doesn't accept any fragmentation. MH The vendor of the device I'm talking to now suggested I use TCP to get MH rid of my fixed IP and that he's also using ICS and doesn't get MH fragmentation (assuming max. bytes sent MTU which is the case here as MH well). MH So what about TCP fragmentation now? How often does it occur in this MH situation? Is it less likely to occur on a lan than on some internet MH connection? Can I influence it in any way? MH I'm using ICS V5 (the one on the partner DVD of Rad Studio 2007).

Re: [twsocket] How to simulate 10053?
Hello DZ-Jay, Try NetStat32 (delphi source provided) it will show you connected TCP on the machine and using del key you can kill each connection you want and generate your error I think. http://smeschini.altervista.org/download/netstat32.php regards. DJ Unplug the network cable midway through transaction? DJ dZ. DJ S.Korotky wrote: Hello All! Is there a way to generate 10053 error from ICS? Calling Abort does close a connection gracefully as well as CloseDelayed (except for a dropped buffered data, if any). Some soft, such as MS IE, often produces 10053 when it closes a connection. FF does not. I need to reproduce this MS feature for testing purposes. Thanks in advance.

Re: [twsocket] Strange e-mail problems Server 2003
Hello Arno, I see in the log that there is 5 seconds delay between DATA and the 10054 error. This may be interesting. During this delay do you send data ? I say this because some server will close cnx if no data transmitted fast enought and do not receive data for xx seconds, usually the timeout is between 1 or 3 minutes but I know a server that wait only 3 seconds (may be bad configuration). The best is to ask client to manualy telnet port 25 into the server and type a SMTP sequence and wait 5 seconds betweent each line you type. Also may be there is some check-back cnx to the client's machine and if FW is ON then machine cannot be checked. regards. AG One of my customers reported problems sending mail with an TSmtpCli AG application when the Windows firewall is turned on. Strange is that AG sending mail data fails for some reason and the server drops the AG connection after ~2 minutes (of inactivity) even though port 25 AG is explicitely opened.

Re: [twsocket] ICS hidden window cannot be created error #8--what isthis?
Hello, Try my little TinyResMeter ( http://www.pesoft.com/trm ) and select the Windows and Handles fields, then you'll see if you reach a big number you must subscribe to get improved 0.97 version but 0.96a should be enought just to view thoses values. regards. rgn there may be also another problem: afaik windows xp 32bit has only 64K rgn handle numbers for windows available. this problem also occurs if you have a rgn lot of apps open, ie. 2 browsers with a lot of tabs, and the the bat rgn email client which uses a lot of handles, also some instances of rgn winrar and explorer. rgn if that condition occurs you cannot open a new window even if you have rgn plenty of ram available, it may be that you open an explorer window rgn and a part is completely gray. rgn you can use taskmanager to see the number of handles a process uses rgn (in the view menu).
