  2. Here is from filezilla : 23:16:31 Status: Connecting to 127.0.0.1:5420... 23:16:31 Status: Connection established, waiting for welcome message... 23:16:31 Response: 220-Welcome to my Server 23:16:31 Response: 220- 23:16:31 Response: 220 ICS FTP Server ready. 23:16:31 Command: AUTH TLS 23:16:31 Response: 234 Using authentication type TLS 23:16:31 Status: Initializing TLS... 23:16:31 Error: GnuTLS error -110: The TLS connection was non-properly terminated. 23:16:31 Status: Server did not properly shut down TLS connection 23:16:31 Status: Connection attempt failed with "ECONNABORTED - Connection aborted". 23:16:31 Error: Could not connect to server 23:16:31 Status: Waiting to retry... From smartftp, the ftp server logged also the same like openssl s_client, filezilla, smartftp : 03/04/2020 23:19:41 - - Disconnected 03/04/2020 23:19:41 - > 127.0.0.1 234 Using authentication type TLS 03/04/2020 23:19:41 - - AUTH C:\TEMP\TLS 03/04/2020 23:19:41 - - Connected So confirmed it's from my ftp server. searching thorough ICS folder or my project file doesn't return a match for 'C:\TEMP' or 'TEMP'.
  3. The reason i am not using more proper FTP Client is because it's faster to paste from windows command prompt. When using openssl s_client working then it will be guarantee to work in full pledges ftp client.
  4. I don't have a clue without someone checking the project out. No, openssl s_client is understand the explicit starttls & ftp protocol, you can check the definition in here : -starttls protocol Send the protocol-specific message(s) to switch to TLS for communication. protocol is a keyword for the intended protocol. Currently, the only supported keywords are "smtp", "pop3", "imap", "ftp", "xmpp", "xmpp-server", "irc", "postgres", "mysql", "lmtp", "nntp", "sieve" and "ldap".
  5. Thank you.

Waiting for IcsHosts for secure ftp server sample.
  6. >> Improving your logging will help, you did not report the response or errors to commands received which is essential to error tracing with bad clients. I haven't know to logging the received command, perhaps you could give me the pointer or sample codes?. Logging in using filezilla or smartftp into ICS sample project is working fine. >>The latest ICS in SVN has FTP server improvements to simplify SSL configuration in the same way as the web and proxy servers two years ago using IcsHosts, but there is no sample to copy yet, you need to look at the multi-web server sample and see how that configures listeners and at http://wiki.overbyte.eu/wiki/index.php/FAQ_Using_IcsHosts. Thanks for the reminder, i am already using latest and greatest SVN commit, but i don't use any proxy as these tests is only from local range. Does that info also relevant with TSslFTPServer? About ICS 8.64 release, does sslTLS_V1_3_SERVER and sslTLS_V1_3_CLIENT will be finalized or completed before the final release?
  7. >> I have no idea how the openssl client tool works or why you are using it to test FTP, but 'AUTH C:\TEMP\TLS' is not a valid command, it should be AUTH TLS'. You have not shown what smartftp sent. I couldn't figure it out why either in the server or client (filezilla) it's sent or received as 'AUTH C:\TEMP\TLS', in smartftp it just mentioned as cannot connect just if as the server is down. >> Since the ICS sample works, you have missed something in your implementation but I can not debug your code. The project was originally as normal plain non-secure FTP server, so i think also it may have missed something in the codes. Currently i cannot quite figure it out to pin point which is wrong. Other than 'barking' at the same tree, i think i will re-base my project with using the ICS sample project in which the project already 'guaranteed' & designed to work. Thanks a lot for all these times.
  8. >> You don't log the IP address and port your server is using, although your client says port 5420 which is not an SSL FTP port, so the server does not attempt to negotiate SSL Using non standard ports for SSL requires extra code. V8.64 has a new Option ftpsAuthForceSsl that might do it simply. Using normal FTP port 21 also doing the same thing in openssl s_client and filezilla/smartftp. I have specified in filezilla/smartftp to do explicit AUTH TLS. Can you tell me on which event or parts for the extra code?, so i can make comparison with the ICS project. Already tried using 'ftpsAuthForceSsl' option but doesn't make any differences :-(. >> Not sure why you are testing an FTP servers with a non-FTP client that does not send the correct protocol. The following command below is sending the correct explicit TLS protocol, first connect with plain text FTP protocol until "AUTH TLS", you can search it on the internet about it. It being used normally for testing TLS server. The specified ftp part is for the FTP testing specification not a port. (using it on ICS sample project is working perfectly) openssl s_client -connect 127.0.0.1:5420 -starttls ftp The same thing from filezilla or smartftp 6:25:37 Status: Connecting to 127.0.0.1:5420... 16:25:37 Status: Connection established, waiting for welcome message... 16:25:37 Status: Initializing TLS... 16:25:37 Error: GnuTLS error -110: The TLS connection was non-properly terminated. 16:25:37 Status: Server did not properly shut down TLS connection 16:25:37 Status: Connection attempt failed with "ECONNABORTED - Connection aborted". 16:25:37 Error: Could not connect to server 16:25:37 Status: Waiting to retry...
  9. What i am trying to achieve is only simple FTPd with only TLS v1.2 working. Original ICS sample is working fine with the same components parameters that i have copied from it, but on my project somehow it doesn't with the same certificates, key, CA. Just tried to generate my own self-signing certificate, key, and CA but the same thing happened. Used the ..\ICS\Samples\Delphi\SslInternet\SslCerts\IcsSslBuildCerts.bat file.

  10. @Angus Robertson Thanks you for taking a look at my thread, that's the problems, Ticslogger is doesn't work in my part, showing up as "Integer Overflow" when starting the x64 server. >>What SSL certificate are you using, and what intermediate, since you are setting SslCaFile. But servers don't use SslCAPath. The 01cert.pem, 01key.pem, cacert.pem are only default one from the ..\ICS\Samples\Delphi\SslInternet folder. What i have tried is also tinkering with the OpenSSL cipherlist and even accepting all cipher with "ALL" still couldn't make it working. Also countless time tinkering with SslMinVersion & SslMaxVersion still no dice, somehow it's like ICS ignoring my configurations/parameters :-(. If you have time, please take a look at my project, i am sure something simple or worse something in the code, upon comparing with beyond compare, i don't notice any big differences.
  11. I am currently confused about my secure FTP daemon in Delphi RIO and using ICS 8.6.4 from the SVN. I have tried to mimic exactly the OverbyteIcsSslFtpServ example project (copy & paste components or manually copying and verifying it). The problem is my project doesn't understand the AUTH TLS handshake. When using openssl client, the result is : Like you have see above, my secure FTPd somehow doesn't serving TLS handshake. Probably my code below is relevant to why it's doesn't work? : procedure TfrmMain.StartServer; var wsi : TWSADATA; SSLType : TFtpSslType; SSLVer : TSslVerMethod; SSLCache : TSslSessCacheMode; SSLCachemodes : TSslSessCacheModes; MinSSLMethod : TSslVerMethod; MaxSSLMethod : TSslVerMethod; SSLTypeModes : TFtpSslTypes; begin { Display version info for program and use components } wsi := WinsockInfo; Logit(Trim(CopyRight)); Logit('Using:'); Logit(' ' + OverbyteIcsWSocket.CopyRight); Logit(' ' + OverbyteIcsFtpSrv.CopyRight); Logit(' Winsock:'); Logit(' Version ' + Format('%d.%d', [WinsockInfo.wHighVersion shr 8, WinsockInfo.wHighVersion and 15])); Logit(' ' + String(StrPas(wsi.szDescription))); Logit(' ' + String(StrPas(wsi.szSystemStatus))); {$IFNDEF VER100} { A bug in Delphi 3 makes lpVendorInfo invalid } if wsi.lpVendorInfo <> nil then Logit(' ' + String(StrPas(wsi.lpVendorInfo))); {$ENDIF} { Set SSL properties, internal session caching enabled } // SslContext1.SslVersionMethod := sslV23_SERVER; //SslContext1.SslOptions := [sslOpt_NO_SSLv2]; //it's unsecure SslContext1.InitContext; //Pre-loads OpenSSL DLL's Logit(OpenSslVersion); Logit(OpenSslCompilerFlags); Logit(OpenSslBuiltOn); Logit(OpenSslPlatForm); Logit(OpenSslDir); frmMain.SslContext1.SslMinVersion := sslVerTLS1_2; { V8.37} frmMain.SslContext1.SslMaxVersion := sslVerMax; { V8.37} frmMain.SslContext1.SslCipherList := CipherListEdit.Text; frmMain.SslContext1.SslDHParamFile := DHParamEdit.Text; { Enables OpenSsl's internal session caching } frmMain.SslContext1.SslSessionCacheModes := [sslSESS_CACHE_SERVER]; frmMain.SslContext1.SslSessionTimeout := 300; //sec frmMain.SslContext1.SslDefaultSessionIDContext := 'AnyStringForSessionCaching'; frmMain.SslContext1.SslCertFile := CertFileEdit.Text; frmMain.SslContext1.SslPassPhrase := PassPhraseEdit.Text; frmMain.SslContext1.SslPrivKeyFile := PrivKeyFileEdit.Text; frmMain.SslContext1.SslCAFile := CAFileEdit.Text; frmMain.SslContext1.SslCAPath := CAPathEdit.Text; frmMain.SslContext1.SslVerifyPeer := VerifyPeerCheckBox.Checked; frmMain.SslFtpServer1.FtpSslTypes := [ftpAuthTls, ftpAuthSsl]; { Use a custom multiline banner } //frmMain.SslFtpServer1.Banner := ''; frmMain.SslFtpServer1.Banner := '220-Welcome to my Server' + #13#10 + '220-' + #13#10 + '220 ICS FTP Server ready.'; frmMain.SslFtpServer1.Addr := ServIpAddr.Text; { V8.37 } frmMain.SslFtpServer1.Port := FPortEdit.Text; frmMain.SslFtpServer1.Start; MinSSLMethod := frmMain.SslContext1.SslMinVersion; MaxSSLMethod := frmMain.SslContext1.SslMaxVersion; for SSLVer := sslVerSSL3 to sslVerMax do begin If SSLVer = MinSSLMethod then Logit('SSL Minimum Version : : ' + GetEnumName(TypeInfo(TSslVerMethod), Ord(MinSSLMethod))); end; for SSLVer := sslVerSSL3 to sslVerMax do begin If SSLVer = MaxSSLMethod then Logit('SSL Maximum Version : : ' + GetEnumName(TypeInfo(TSslVerMethod), Ord(MaxSSLMethod))); end; //Logit('SSL Minimum Version :' + String(frmMain.SslContext1.ToString) ); //Logit('SSL Maximum Version :' + ToString(frmMain.SslContext1.) ); SSLCacheModes := frmMain.SslContext1.SslSessionCacheModes; for SSLCache := sslSESS_CACHE_CLIENT to sslSESS_CACHE_NO_INTERNAL_STORE do begin If SSLCache in SSLCacheModes then Logit('SSL Session Cache Modes : ' + GetEnumName(TypeInfo(TSslSessCacheMode), Ord(SSLCache))); end; Logit('SSL Session Timeout :' + UIntToStr(frmMain.SslContext1.SslSessionTimeout) + 's' ); Logit('SSL Certificate File :' + frmMain.SslContext1.SslCertFile ); Logit('SSL Private List :' + frmMain.SslContext1.SslPrivKeyFile ); Logit('SSL CA File :' + frmMain.SslContext1.SslCAPath + '\' + frmMain.SslContext1.SslCAFile ); Logit('SSL Verify Peer :' + BoolToStr(frmMain.SslContext1.SslVerifyPeer) ); SSLTypeModes := frmMain.SslFtpServer1.FtpSslTypes; for SSLType := ftpAuthSsl to ftpImplicitSsl do begin If SSLType in SSLTypeModes then Logit('FTP SSL Types : ' + GetEnumName(TypeInfo(TFtpSslType), Ord(SSLType))); end; Logit('Successfully Started the FTP Server'); end; Full project files attached below, been spending more than 10 hours trying to debug it but no matter what i have tried, it doesn't serving TLS.
