[DataSpider Servista] Please let me know about cipher suites available for FTP over SSL / TLS of FTP adapter.

We want to connect to the FTPS server using FTP over SSL / TLS (FTPS) with the FTP adapter. Please tell me about cipher suites that can be used at this time.
Category : 

Answer

Available cipher suites differ depending on the version of DataSpider Servista.
 
You can output the communication status with the FTP server to the server log by adding the following settings to the properties file.
Please check the list of cipher suites included in the output log message.
 
■How to check
Add the key to the following three properties files, after you restart the DataSpiderServer, please run the connection test to the FTP server.
 
  • Property file
$DATASPIDER_HOME/server/conf/system.properties
  • Key
edtftp.log.log4j=true
 
  • Property file
$DATASPIDER_HOME/server/conf/dslog.properties
  • Key
log4j.logger.puretls=DEBUG
 
  • Property file (create folder and file and add key)
$DATASPIDER_HOME/server/plugin/data_processing/modules/ftp_adapter/com/enterprisedt/net/ftp/ssl/edtftpjssl.properties
  • Key
edtftp.log.puretls.level=65535 

■Example of log output
The following log message is output to $ DATASPIDER_HOME / server / logs / server.log.

■Noted
  • Because the output volume of log becomes huge, please reset the setting after confirmation.
  • Cipher suites that use AES 256 included in the output cannot be used because Java 8 falls under the following restrictions.
  • Import restriction of the encryption algorithm
