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)!!!
Edit: now I tried to delete the files from home, it was OK, then moved with my laptop to office (without closing Filezilla) and suddenly it was also OK! But yesterday from office the deletion stopped after almost 400 files. Interesting! Maybe it depends where I log in first?
