Passive FTP isn't passive on the second connection

[Adrian Marsh]

Hi,

SW: Filezilla Client 3.3.3, Windows XP SP3

I'm testing a PROftp server (externally hosted, on the Internet) to debug something. To help, I've also set one up internally on my LAN, and wanted to use Filezilla as the client. I'm testing on the LAN server first so I understand the ports in use etc.

However, Filezilla doesn't switch to PASV on the second time I connect to the server.

I define the server, and make sure that under Transfer Settings, its set to Passive.

I then login (log 1). you can see Filezilla correctly sent PASV. All looks good
I then disconnect, and re-login again (log 2) by clicking on the drop-down toolbar. You can see from the log that the client doesn't switch to PASV.

The only way I've been able to re-connect in passive, is to close Filezilla and restart it.

I can't find this in the existing buglist.

Client and Server are on the same LAN.

Since FileZilla is reconnecting the directory listing isn't transferred again and no data connection is established. Try entering a directory or pressing F5 for refresh and I guess you will see the PASV command.

Hi, Im not really sure I agree here... if the client is reconnecting, then it should enter in a fresh state, not be remembering some last state.
