Hello, I thought I would do some testing with TSslFtpClient (version V8.09).
I downloaded and installed ProVide server (https://www.provideserver.com/free-trial/) on another computer, setup it up for normal FTP and it worked for getting a file Altered the settings to support FTPS Implicit SSL/TLS, set the TSslFtpClient.SslType to sslTypeImplicit, and getting the file worked. Altered the settings to support FTPS Explicit SSL/TLS, set the TSslFtpClient.SslType to sslTypeAuthTls, and getting the file worked. Altered the setting TSslFtpClient.SslType to sslTypeAuthSsl, and getting the file failed. Here is the log from ProVide: 2018-07-12 10:02:30 - (not logged in-94) (192.168.1.189) ! New user connected from 192.168.1.189. Using FTP protocol.

Disconnected (ftps). The next to the last line shows the connection closed abnormally. Is using type sslTypeAuthSsl not expected to work? When configuring the server for Explicit the log shows: 2018-07-12 10:04:37 - ! FTP Server active on 21 (Explicit SSL/TLS, certificate "ProVide" with 2048 bits accepting SSL v2, SSL v3, TLS v1, TLS v1.1, TLS v1.2) Is there an option in the TSslContext I need to set? Also, what is the ProtLevel C or P? (Complete, Partial?) Thanks, Mark P.S. I can post the icsLogger log but it was kind of long so did not. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
