Issue/Introduction

Reporter supports both FTP and FTPS (i.e. FTP over SSL) and can be enabled at the same time.   

 

Environment

Reporter version 11

Cause

FTP and FTPS services are both enabled and configured to use same command channel/port 

Resolution

Port 21 can be used for FTP or FTPS.  

Use different ports (e.g. 21 for FTP and 990 for FTPS)  when both service are enabled. 

 

Additional Information

FTP default command channel/port is 21 while data channel/port varies.  Active FTP data channel connection will be initiated by FTP server which could be dropped by firewall.  Due to this reason, many preferred to use passive FTP.    

FTPS protocol has implicit and explicit.  Implicit FTPS negotiation was not defined in in RFC 4217 , it is considered a deprecated  protocol and not supported.  Reporter supports explicit FTPS.
