Hi,

I need to connect to ftp server with Indy 10 components and SSL (ftps)

My code works perfectly on Windows with ssleay32.dll and libeay32.dll
in the .exe folder.

When I try to use the same source code under Linux it does'nt works
with this error message : SSL negotiation failed.

Do I have to install a special package to compil under Linux ?
Do I need to have special files in the folder ?

Thank you for your help.

Serge

Which version of the OpenSSL library files are you using on Linux? 
Assuming you are using Indy's default SSLIOHandler for OpenSSL, it
only supports OpenSSL 1.0.2 and earlier, is that the version you are
using?  What does Indy's IdSSLOpenSSL.OpenSSLVersion() function
report?  If you need to use OpenSSL 1.1.x or later, use this
SSLIOHandler instead (work-in-progress).

Just the library files for OpenSSL.

Hi Remi,

Thank you for your response.

I am using OpenSSL 1.1.1j  16 feb 2021

If I print the version of Ftp.IOHandler.Version I got : 10.6.2.5475

The github link does'nt works :-(

Then you cannot use the default SSLIOHandler, as it does not support
that version of OpenSSL.  You must use the WIP SSLIOHandler on GitHub.

That is the Indy version, not the OpenSSL version.  After Indy has
loaded OpenSSL into memory, you can call the OpenSSLVersion() function
in the IdSSLOpenSSL unit, as I stated in my previous reply.
