FileZilla Forums

Yes, assuming pings are reasonable and there's no packet loss you can easily saturate gigabit links with FileZilla. Note that for this to work the server must have configured a sufficiently large TCP advertised receive Window that's at least as big as the bandwidth-delay product.

You need to update to the most recent version of FileZilla, old versions are not supported.

Currently working on a great new feature where FileZilla will simply know based on the elapsed time that some unknown new version is available even if checking is disabled.

Yup, that's a violation of REQ-5 from RFC 5382:

If a NAT cannot determine whether the endpoints of a TCP connection are active, it MAY abandon the session if it has been idle for some time. In such cases, the value of the "established connection idle-timeout" MUST NOT be less than 2 hours 4 minutes.

Setting up an FTP server with FileZilla Server is quite straightforward: After installing, all you need to do is to create at least one user and to configure the networking settings due to using a router, see our Network Configuration guide for instructions. You can test your configuration on https://ftptest.net/

If it's just a weak cipher issue there would be an error message about this. Getting no response at all typically means firewall.

Every time a new connection is established, the client needs to authenticate with the server. If the server requires 2FA, then you need to enter the second factor. No way around this.

Please make sure you are using the very latest version. After having done so, which version are you using?

Cannot reproduce. There are no functional changes between the current and the previous version that could possibly cause such speed differences.

Are you by chance using some faulty firewall or AV product that slows down the new version?

Failure to receive a reply to the AUTH command is almost always the result of a malicious firewall actively sabotaging the connection.

Can you ping the server from the command-line?

That's the whole point of two-factor authentication, to be as annoying as possible.

It's a false-positive.
