    How to limit ciphers and groups in tls connection?

    Can you please confirm your query only relates to the ICS SSL server, and not clients? From your comments, I assume you are not using IcsHosts to specify certificates and SSL parameters? Angus

    ISC 9.1 as a library events not firing

    There is a terminology issue here, Websocket is a specific protocol based on HTTP. TWSocket is the name of the base ICS component for all low level socket operations, and does not handle high level protocols like Websocket. ICS has a TSslWebSocketCli component, there is a simple function doWebSocketClick in the OverbyteIcsSnippets sample you can build and run which accesses one of my servers, or a full example in the OverbyteIcsHttpRestTst sample that should allow you to access your site. ICS has several console samples, but they are no longer in the main distribution not being needed very often, I'll have to look one out. Angus

    TIcsFtpMulti failing... (Version 8.65)

    Somehow, you are not passing a file name for the upload, or it being lost. But the component should stop you doing that... The reason may be in the log which should have the file name a few times already. Angus

    TIcsFtpMulti failing... (Version 8.65)

    As I requested earlier, please email the complete log for the transfer, selected excerpts are meaningless. But please disable low level diagnostics. The problem is clear from the log, renaming is failing due to no new file name, the log might show something earlier. You could set the option 'no temp file for xfers' which is a quick fix, that feature goes back to the days of dial-up modems where dropped internet connections were common. Angus

    TIcsFtpMulti failing... (Version 8.65)

    All newer high level ICS components have a logging event for display, progress and file logging, slightly different names in different components, the FTP one is CopyEvent as used in the Xfer sample. The FTP close problem I fixed was time related, a network appliance may close the FTP control channel during a long data transfer due to inactivity, so nothing happens after the data connection closes, The solution was to send periodic commands on the control channel, if the server accepts them. I had the problem after two hours. Angus

    TIcsFtpMulti failing... (Version 8.65)

    Sorry, that logging level was only ever designed to debug SSL operations, and does not show any FTP commands, so I've no idea what your application is doing or what error messages are being reported, not even whether you are using SSL/TLS. Can you please email me the normal log of the complete session, showing all commands and files. Also, your component is four years old, there was a fix for aborted uploads in V8.71 that related to those taking over 30 minutes, a 50GB file in my case. Angus

    Delphi 2007 and XE5 Crashes on Windows 11

    I have Delphi 2007 installed on Windows 11, use it weekly without any real problems, although it does crash more often than modern compilers on the same PC, which also crash. Angus

    ICS V9.2 announced

    ICS V9.2 has been released at: https://wiki.overbyte.eu/wiki/index.php/ICS_Download ICS is a free internet component library for Delphi 7, 2006 to 2010, XE to XE8, 10, 10.1, 10.2, 10.3, 10.4, 11 and 12 and C++ Builder 10.4, 11 and 12. ICS supports VCL and FMX, Win32, Win64 and MacOS 32-bit targets. Beware Mac OS-X and C++ have not been tested recently due to lack of support from such users. The distribution zip includes the latest OpenSSL 3.0.14. 3.2.2 and 3.3.1, for Win32 and Win64. Changes in ICS V9.2 include: 1 - V9.2 is a minor release, fixing a few issues introduced in the last major release, and other bugs located since. There are no breaking or installation changes from V9.1, but if updating from earlier releases please read https://wiki.overbyte.eu/wiki/index.php/Updating_projects_to_V9.1 2 - TIcsMailQueue can now queue a prepared EML file created by another application, or perhaps received by the SMTP Server. Added optional SkipEmpty argument to StartMailQu method so queue is not started unless there are pending emails waiting to be sent. The sample has 'Send Prepared EML File' to queue an existing EML file rather then preparing email with properties. 3 - Improved email MIME decoding by supporting embedded boundaries, usually for multipart/alternative parts, within a multipart/mixed message, using code written 20 years ago but suppressed for some reason. Previously these parts were sometimes left encoded within a part. There is a new property LooseRFC to allow decoding if the boundaries in the body are missing the two required hyphens, usually because the boundary also begins with hyphens. TMimeDecodeEx should now always return the body if no MIME parts are found, and TPartInfo has PLevel which is Part Level, and PInfo which is displayable part information for logs. The MimeDDemo sample has various improvements to test these features. 4 - Fixed a nasty Win64 problem reading EC certificates from the Windows Store, which may have caused server crashes, also reproducible in the PemTool listing the Windows Store. This was due to Win64 bad initialisation of a buffer used for a Crypto API call that failed. 5 - The HTTP client now checks the URL always has / at start of the path, ie add it for test.com?query. In the REST client, added a sanity check for RawParameters to encode any spaces, which can break the HTTP request. After a file download completed, check actual file size against response size. The multipart/form-data MimeBoundary no longer includes extra -- at start that are required preceding boundaries within parts, some web servers may have been unable to decode our MIME encoding. 6 - The HTTP server has a new method AnswerRedirect for various redirection responses to a new URL. When accessing the default document in a path without a trailing path delimited /, redirect using 301 to the correct path with delimiter instead of adding it locally and displaying the document which will then incorrectly link to pages in a higher level directory. Using the THttpOption hoAddMissPath redirects if the default document is missing perhaps a template or virtual document. Fixed a bug where authenticated POST/PUT requests always returned a 404 error. Added AnswerBodyTB client response with TBytes binary, similar to AnswerString, tested in the sample by supporting favicon.ico request. Check if the request HTTP version gets corrupted due to spaces in the URL, which are not allowed. The SslMultiWebServ sample has new web pages to test POST/PUT and template authentication. 7 - TSslX509Certs has a new function CertResetDomain to reset a certificate order state to None, if the order process stalls or gets confused due to errors. If AcmeV2StartChallgs fails because there are no pending challenges, reset to order to None so it starts again next time and does not loop. 8 - ICS not longer tries to load OpenSSL RAND_screen function that may be missing from recent DLLs. 9 - TIcsHttpMulti fixes a bug introduced in V8.66 that stopped the application setting authentication, rather than adding it to the URL, and a Win64 free stream bug. 10 - TIcsIpStrmLog correctly counts failed client connection attempts if ping is not used first to check the remote IP address. The sample has a new client Retry Attempts box to test this. 11 - Updated the Snippets sample to use authentication to access some the hardcoded URLs, which started failing after authentication was added to test web server bugs (see above). 12 - Added OverbyteIcsHttpThrd sample to show how to use TSslHttpRest component in a multi-threaded program. 13 - Improved Posix support for Linux and Android, not tested or supported yet. Beware SSL does not correctly load for Posix at the moment. 14 - Added support for a new feature release of OpenSSL 3.3 with {$DEFINE OpenSSL_33} in the Defs.inc file, ICS includes new versions of the active versions, 3.3.1, 3.2.2 and 3.0.14, but no longer includes 3.1 since there are two newer feature versions. 15 - Updated the 'ICS Intermediate Short' SSL certificates, used by ICS to generate temporary server certificates to allow SSL servers to run until a Let's Encrypt or commercial certificate is installed. It now expires after 200 days, 21st December 2024, after which self signed certificates will be used instead, unless a newer 'short' is installed. 16 - Only Delphi 10.41 and 10.42 (10.4 with updates 1 or 2) will install correctly with the new install packages, the original RTM version does not support the package LIB suffix: $(Auto) so you must change it manually for each package to 21.0. The release notes for V9.2 are at https://wiki.overbyte.eu/wiki/index.php/ICS_V9.2 All ICS active samples are available as prebuilt executables, to allow ease of testing without needing to install ICS and build them all. There are four separate zip files split into clients, servers, tools and miscellaneous samples which can be downloaded from https://wiki.overbyte.eu/wiki/index.php/ICS_Samples Angus

    ICS V9.2 announced

    Just check all the C++ package options are sensible, and match those of the latest Delphi packages, I may have missed something since I've never managed to build a C++ package. Angus
  11. ICS is a free component library used to build software applications, there are no export approvals for ICS, country of origin is the world, it contains code from multiple countries. Angus

    Dropping component on form

    When you drop a component on a form, the IDE automatically adds the unit to the uses clause. Is there a way for that component to get the IDE to also add a second unit on which it is dependent? Angus
  13. Angus Robertson

    Dropping component on form

    Added a few lines to the ICS design package registration unit, and two extra units are now being added automatically when components are dropped on forms, or those forms are accessed in the IDE. Would not have been possible without a Stack Overflow answer by Remy Lebeau, Aug 19, 2020: Have your design-time package implement a class that inherits from TSelectionEditor and overrides its virtual RequiresUnits() method, and then register that class for your component using RegisterSelectionEditor(). This way, whenever you place your component onto a Form/Frame/DataModule Designer at design-time, any additional units you report from RequiresUnits() will be added automatically to that unit's uses clause when the unit is saved. uses ..., DesignIntf; type TWebBrowserWrapperSelectionEditor = class(TSelectionEditor) public procedure RequiresUnits(Proc: TGetStrProc); override; end; procedure TWebBrowserWrapperSelectionEditor.RequiresUnits(Proc: TGetStrProc); begin inherited RequiresUnits(Proc); // call Proc() for each additional unit you want added... Proc('MyWrapperUnit'); Proc('MyUtilityUnit'); end; procedure Register; begin RegisterComponents('My Wrappers', [TWebBrowserWrapper]); RegisterSelectionEditor(TWebBrowserWrapper, TWebBrowserWrapperSelectionEditor); end; Angus

    Dropping component on form

    ICS now only needs to add two units to meet almost all event handler type needs. Users of old compilers can not always get the same features as newer compilers, so may have to add uses manually, as everyone has for 25 years. There is an argument for only supporting new compilers, but I still have a commercial application using Delphi 2007, so support for that will not be dropped any time soon Angus

    Dropping component on form

    Thanks Uwe, will try this next week. Angus
  16. Angus Robertson

    Dropping component on form

    That is exactly what I need, and for that reason, but this if for dozens of existing components and I assume they would need to be changed to be derived from TSelectionEditor. I also need compatibility with Delphi 2007 and later, ideally. Angus

    ICS V9.2 announced

    ICS V9.3 in SVN should now build for C++ Builder, there are new defines to make all the Windows Certificate Store code including WinCrypt optional, which are disabled by default for C++, I've removed WinCrypt from the package. Angus

    ICS V9.1 announced

    ICS has never been supported on Linux. There is preparatory work for Linux work, I created a new SSL sample PemTest last month which works on Linux, but socket based components don't work yet, this will be fixed soon by replacing the old MacOS event engine in WSocket with a new version that supports all platforms, a test version is currently in the ICS V10 SVN repository, no SSL.

    TRestClient, TLS 1.2, & Windows Server 2012 R2

    I used to support a Windows 2012 R2 (Windows 7) server, and keeping SChannel SSL running was a pain, since TLS/1.2 was never part of the original OS and had been added with patches. The main problem was it kept forgetting SChannel TLS/1.2 ciphers, usually after each reboot. Before rebooting, I always used the IISCrypto tool from https://www.nartac.com/ to select all the required ciphers, specifically ECDHE ciphers since I use EC key certificates which Microsoft does not like. Servers using OpenSSL worked fine of course. Angus

    What is the best way to accomplish this?

    I've just written a similar application using ICS components, a server listens for remote clients to connect, those connections are kept open permanently with a tiny data packet periodically, and the server can send commands back to the clients when required. This application is actually server monitoring locally, if the remote client stop communicating, the server will restart the Windows service. I wrote a similar system 20 years ago using ICS monitoring vehicles using wifi (before 3G) and triggering FTP uploads (CCTV) from them. Angus

    TRxTrayIcon started misbehaving

    I've been using TRxTrayIcon from RX tools for about 25 years, with various versions of Windows and Delphi. Without changing anything, on Windows 11 I've started getting an exception on ResumeThread when the component is asked to animate the tray icon using a timer thread. This might have happened when I updated to Delphi 11.3 a few months ago, not sure. Anyone else still using RX Tools? The Polaris unicode version. Angus
  22. Thanks, I'll test against Mosquitto MQTT server for the next release, and adapt the component if possible, but we don't always try to work with buggy or old servers. Angus
  23. As I said, I've never really looked at the MQTT protocol. Is it now working? Are there changes we should be making to the MQTT component or sample to make it work with other servers and clients? Angus
  24. Have you tried building and testing the OverbyteIcsMQTTst sample? It contains both client and server components, to send to each other. There is a publish button, does it work? Sorry, I know little about MQTT, not used it for any of my own projects, this is a contributed component that I improved for SSL and the latest ICS,. The sample seems to work OK, but please let us know if it does not work as expected, it has not been tested against non-ICS clients or servers. Angus

    Buffered Byte Count for SSL Socket

    Must say I've never used BufferedByteCount myself, don't think it's used in any ICS components. But if an SSL version is useful, please email your changed unit and it will be added, please make sure you update the latest version from SVN. My email is in many units. Angus
