TCP.Capture (Indy 10?)


TIdUDPClient is the base UDP client for sending UDP packets to other destinations. The mostcommonly used method is Send, which uses the Host and Port properties to send a UDP packet. Itaccepts a string as an argument.

There is also a SendBuffer method which performs the same task as Send, except that it accepts aBuffer and Size as arguments.

TIdUDPClient can also be used as a server of delphi indy error to wait and receive incoming UDP packets on anindividual basis.

TIdUDPServer when active creates a listening thread to listen for inbound UDP packets. For each UDP packet received, delphi indy error, TIdUDPServer will fire the OnUDPRead event in the main thread, or in the context of the listening thread depending on the value of the ThreadedEvent property.When ThreadedEvent is false, the OnUDPRead event will delphi indy error fired in the context of the main program thread. When ThreadedEvent is true, the OnUDPRead event is fired in the context of the listener thread.When ThreadedEvent is true or false, its execution will block the receiving of more messages. Because of this the processing of the OnUDPRead event must be quick.


Introduction to Indy

Connection Closed Gracefully

The TTL property is declared as protected in TIdRawBase, and TIdIcmpClient does not promote it to public. You will have to declare a descendant class to gain access to it, ie:

TIdIcmpClientAccess = class(TIdIcmpClient);
procedure TMainForm.PingFirst;
//., delphi indy error.
TIdIcmpClientAccess(IdIcmpClient1).TTL := CurrentTTL;

Along with ICS and Synapse, Indy is one of the most use open-source set of Internet components. It supports HTTP, SMTP, ICMP, etc.

Note: All Indy exceptions descend from EIdException. By default, Delphi 7 has at least one item in Tools > Debugger Options > Language Exceptions related to Indy, "Indy EIDSilentException Exceptions", and, possibly "Indy EIDSocketError Exceptions". which do not prevent the IDE to fail when running in the by design exception EIdSocketError "Socket Error # 10004". The reason is that the actual exception is "EIdSocketError", not "Indy EIDSocketError Exceptions". Add the former through the Add button, don't forget to add IdException in the delphi indy error section, and you won't be stopped by the IDE anymore.

Upgrading to Indy 10

Delphi 7 ships with Indy 9. Since the only documentation on the Indy website is now based on release 10, delphi indy error, and some examples won't work with older releases, you delphi indy error remove Indy 9 from the IDE, and install release 10, delphi indy error.

There are two possibilities, but both require your uninstalling Indy 9 yourself before installing Indy 10:

Removing Indy9:

  1. Close the Borland Delphi IDE if it is open.
  2. If you are using the version of Indy included in Delphi 6 or 7, use the MSI installer to remove Indy: In "Program Files", delphi indy error, click on the drop-down list before Indy, and select Do Not Install. If you didn't install Corba, uncheck "Use Visibrocker/CORBA Support" before proceeding with the uninstall
  3. Remove all Indy files from the Delphi directory, including dclIndy*.bpl, Indy*.bpl, the Id*.pas, and the Id*.dcu's.  Take care that you only remove the old Indy files and not something else.  Be sure that you also remove any Indy*.bpl from your Windows\System32 directory (IndyCore70.bpl, delphi indy error, IndyProtocols70.bpl, and IndySystem70.bpl)
  4. When restarting Delphi, it will fail loading the Indy 9 BPL: "Error/Can't load package c:\program files\borland\delphi\Bin\dclindy70.bpl. The specified module could not be found. Do you want to attempt to load the package the next time a project is loaded?" Just tell it not to try reloading this package the next time.

Manually installing Indy10

  1. Place the new version of Indy in a directory of your choice.  When unzipping, please keep the \source directory for the archive intact because that is used by some build batch files.
  2. In the source directory, there are several batch files.  Run the appropriate one for your version of Indy:
    • FULLD4.BAT - Delphi 4
    • FULLD5.BAT - Delphi 5
    • FULLD6.BAT - Delphi 6
    • FULLD7.BAT - Delphi 7
  3. These batch files create subdirectories in the main Indy directory folder.  They are (D4 for Delphi 4, D5 for Delphi 5, D6 for Delphi 6, and D7 for Delphi 7).  These directories contain:
    • The Indy .DCU's
    • The Indy Design-Time .BPL
  4. In your Delphi IDE, delphi indy error, add the Indy design-time package with Component

    Delphi 10.4 error:1408F10B:SSL SSL3_GET_RECORD:wrong version number #372


    with the Indy version of Delphi 10.4 we are having issues using TLS for a TCP server / client system. I have a testtool which works perfectly when compiled with Delphi 10.3. With 10.4 we delphi indy error getting an error, if the clients wants to connect:

    The code of the server app is

    procedureTForm1.FormCreate(Sender: TObject); begin IdServerIOHandlerSSLOpenSSL.SSLOptions.CertFile := 'S:\certs\pc.pfx'; IdServerIOHandlerSSLOpenSSL.SSLOptions.KeyFile := 'S:\certs\pc.pfx'; IdServerIOHandlerSSLOpenSSL.SSLOptions.RootCertFile := 'S:\certs\ca.cer'; IdServerIOHandlerSSLOpenSSL.SSLOptions.Mode := sslmServer; IdServerIOHandlerSSLOpenSSL.SSLOptions.SSLVersions := [sslvTLSv1_2]; IdTCPServer.DefaultPort := 8888; IdTCPServer.Active := true; end; procedureTForm1.IdServerIOHandlerSSLOpenSSLGetPassword(var Password: string); begin Password := 'Password'; end; procedureTForm1.IdTCPServerConnect(AContext: TIdContext); beginif AContext.Connection.IOHandler is TIdSSLIOHandlerSocketBase then TIdSSLIOHandlerSocketBase(AContext.Connection.IOHandler).PassThrough := false; memLog.Lines.Add('Connect: ' + AContext.Binding.PeerIP); end; procedureTForm1.IdTCPServerExecute(AContext: TIdContext); begin// print to logend;

    For the client it looks like this:

    procedureTForm2.FormCreate(Sender: TObject); begin IdSSLIOHandlerSocketOpenSSL.SSLOptions.VerifyMode := []; IdSSLIOHandlerSocketOpenSSL.SSLOptions.VerifyDepth := 0; IdSSLIOHandlerSocketOpenSSL.SSLOptions.SSLVersions := [sslvTLSv1_2]; IdSSLIOHandlerSocketOpenSSL.SSLOptions.Mode := sslmClient; IdTCPClient.Host := ''; IdTCPClient.Port := 8888; IdTCPClient.ReadTimeout := 50; IdTCPClient.Connect; end;

    The SSL IO handler is set via DFM to the server/client.

    What I have found out so far: There is no exception and apps can communicate, if I do not set the to in the connect event in the server. But if the delphi indy error is not set tothe tcp connection is not secured server activesync 3031 error I can read sent messages in Wireshark in plain text.

    I also think the issue is in the client. I come to this conclusion as I tried running the client delphi indy error server compiled with the different Delphi versions:

    Delphi version used to compile clientDelphi version used to compile serverResult

    Do you have delphi indy error idea about changes which may cause that behaviour? Anything I could do to provide more information about the issue?

    I'm using TIdHTTP component to execute GET command, resulting in above error message:


    Method - sslvSSLv2
    Can someone help me on this?

    I try to upgraded to Indy version 10 but I cannot find TIdHTTP, what should I do?

    I already answered your exact same question 4 days ago on StackOverflow:

    Delphi 7 and Indy 9.0 Error Connecting SSL

    That is 2 days before you posted it here.  Why are you asking the same question again, delphi indy error, in a different forum, without regard to an delphi indy error already given to you earlier?  That is delphi indy error bad forum etiquette.

    For the benefits of other readers, I'll copy my StackOverflow answerhere:

    rlebeau Wrote:NOBODY uses SSL v2.0 or SSL v3.0 anymore, as they are no longer secure. You need to use TLS v1.0 at a minimum (1). Indy 9's TIdSSLIOHandlerSocket component supports up to TLS v1.0 max. Set the SSLOptions.Method property to sslvTLSv1 for that.

    1: be aware that websites have slowly been dropping support for TLS v1.0, and major webbrowser vendors are dropping support for TLS v1.0 and v1.1 later this year.

    To use TLS v1.1 and delphi indy error, you need to upgrade to Indy 10, where TIdSSLIOHandlerSocket has been renamed to TIdSSLIOHandlerSocketOpenSSL, and its SSLOptions.Method property has been deprecated in favor of a new SSLOptions.SSLVersions property, which will allow you to enable TLS v1.0, v1.1, delphi indy error, and v1.2 at the same time.

    On a side note, you do not need to use the TIdHTTP.Request.CustomHeader property to use Basic authentication. TIdHTTP has built-in support for Basic. Simply set the TIdHTTP.Request.BasicAuthentication property to True and then use the TIdHTTP.Request.Username and TIdHTTP.Request.Password properties:


    This works in both Indy 9 and 10.

    Indy 10 has TIdHTTP, so if you can't find it then either you are looking in the wrong place for it, or you did not install Indy 10 correctly to begin with.
