OverbyteIcsSslFtpTst not connecting

[AllanF 0]

Hi ,

I am not able to connect to a SSL site with OverbyteIcsSslFtpTst.exe whereas with FileZilla it connects.

'Test.Rebex.Net'  allows us to test SSL FTP site.  OverbyteIcsSslFtpTst.exe  connects to the non-SSL  site and gives me directory list, whereas with SSL it does not connect. I have copied libcrypto-1_1 and libssl-1_1 in Exe folder too.

I have compiled with Delphi Seattle.

 

 

With SSL port 990

Very unusual to see access violations with OpenSSL, most likely mismatched DLLs or a very old version of ICS and a newer OpenSSL.  Certainly nothing wrong with the components, use SSL all the time.  What about other ICS SSL samples, so they all fail as well?

I copied the latest dlls then too same issue. Do I have to have any of these PEM files ,certificates etc ?   The other SSL (Explicit)  too fails

[Angus Robertson 574]

SSL clients don't need certificates.  Are the DLLs in the same directory as the application, if not you may be opened rubbish from elsewhere on the PC. 

 

And try other samples, to see if just one failing, specifically try  OverbyteIcsXferTst.dp which is a far more advanced FTP client with better error handling.

DLLs are in the same directory as the application.

OverbyteIcsXferTst works fine !!

Will check and get back if necessary.
