Repro:

1. Start a big file download.
2. Reboot the server to force the connection to drop. I used a Windows 2012 R2 IIS FTP site and rebooted the entire machine.
3. Observe, that the file transfer starts anew. This is a problem if the file takes a few days to download. A lot of progress is lost.

Note, that the typical dialog asking the user how to resolve a conflict (skip, overwrite, resume, ...) did not appear.

Desired behavior: Ask the user or simply resume the file download.

The Filezilla log showed the following during the connection outage:

Some earlier connection problem that apparently was resolved by restarting:

Command: RETR FILENAME Response: 150 Opening BINARY mode data connection. Response: 226 Transfer complete. Command: PASV Response: 227 Entering Passive Mode (IP,216,163). Command: REST 50930845561 Response: 350 Restarting at 50930845561. Command: RETR FILENAME Response: 150 Opening BINARY mode data connection.

Status: Connected Status: Starting download of PATH/FILENAME Status: Testing resume capabilities of server Command: TYPE I Response: 200 Type set to I. Command: PASV

... A few hours later the server reboot:

Command: RETR FILENAME Response: 150 Opening BINARY mode data connection. Error: Could not read from transfer socket: ECONNRESET - Connection reset by peer Error: Connection timed out Error: File transfer failed after transferring 8 GB in 3380 seconds Status: Resolving address of HOSTNAME Status: Connecting to IP:PORT...

These messages were repeated a lot. Lots of retries. Now Filezilla gives up to restart:

Should be easy to repro. I have had this problem many times already.

Sometimes, sleeping the client machine at night and resuming it in the morning also causes this issue.

Version: 3.10.02. Has been happening for a long time, though. Nothing new.

I'm running on Mac OSX, and I don't recall having this problem with FileZilla on PC.

Please fix this ASAP or I'll have to abandon your fantastic, amazing project.

My project is very large and accesses many files on the server. When I backup the server via FileZilla, this limit causes me to miss backing up files without even knowing it.

i needed this for my own server. it runs on a machine that is behind a firewall which i can not administrate. only two ports are usable by me, so i chose one to be the "ftp access port" and wanted to use the other one as "passive mode port". looking at the server itself, i saw that it is already possible to handle that situation. so the only thing to change was the server interface. the patch does this and also corrects the error message.
