This happens only when using Windows Shell FTP command to connect to Cerberus server. All other client/server combinations tried seems to be OK. Server Bug? Or is it just that Windows FTP cannot handle passive mode? I tried issuing literal pasv command.
Spcifically, using Ipswitch WS_FTP and other FTP clients like FileZilla are able to work just fine. On the server side, FileZilla FTP server on the same machine is working fine, end-to-end when using windows command line FTP to login. Stopped FileZilla, trying Cerberus –
However, Cerberus is not allowing anything after user login. In order for the server to work, had to uncheck Security and set PASV options to “Dont use External…” and to specify PASV IP.
