I am downloading thousands of files over FTP using Filezilla. The download takes several hours, so I want to run it overnight, but there is a problem - Filezilla keeps re-asking the password every now and then - almost like every 10 minutes! Why? How to fix this?
I've enabled FileZilla to establish 2 simultaneous FTP connections. It is strange that FileZilla keeps re-asking for password, even if I have set
Logontype to "Ask for password". Snip from the documentation:
Ask for password: FileZilla asks you the password during logon, and it remembers the password during the session.
Interactive: FileZilla asks for the password, and asks again for every new connection to the server.
This means that when I set "Ask for password", it shouldn't ask for every new connection to the server. Yet it does ask again and again...
Site manager settings:
The log just after Filezilla re-asks the password (with 1 simultaneous connection only the log looks exactly the same):
Command: PASV Response: 227 Entering Passive Mode (81,31,47,235,239,66). Command: RETR P034624.jpg Response: 150 Opening BINARY mode data connection for P034624.jpg (1242518 bytes) Response: 226 Transfer complete Status: File transfer successful, transferred 1 242 518 bytes in 1 second Status: Starting download of /avif/photos/orig/P034625.jpg Command: PASV Error: GnuTLS error -53 in gnutls_record_send: Error in the push function.

Screenshot of the log right after Filezilla re-asks the password:
If I switch to Active mode, the download works without re-asking the password!!! (Tested with 1 simultaneous connection and Timeout = 0).
But, delete doesn't work - it will break the connection after like 400 deleted files in both active and passive mode, 1 sim. connection, timeout 0. This time it doesn't re-ask the password, it just stops. The log:
Command: DELE P025791.jpg Response: 250 DELE command successful Command: DELE P025792.jpg Response: 250 DELE command successful Command: DELE P025793.jpg Error: GnuTLS error -53 in gnutls_record_send: Error in the push function.

The above testing was done from my office, Windows 7, behind Zyxel P660HW-T3 FW/modem with more or less default settings. Switching to passive mode has helped here for downloading, for deleting no remedy found. When I tried from home, Windows XP, Filezilla 3.7.3 (current), behind Edimax BR6225N/BR6226N FW/modem, it both downloading and deleting went all OK even with default settings (timeout = 20, 2 sim. connections, passive mode)!!!
