Custom Query (8174 matches)

I have several dozen SSH key pairs on this system. When trying to connect to an OpenSSH 2 server using the SFTP protocol, and try to authenticate with a password (as provided in the site manager), authentication fails and I end up with this message:

Too many authentication failures for <username>

What happens is that FileZilla uses pageant, detects thse key pairs I have, connects to the server and doesn't send my password, but tries as many of those key pairs as it can, which I have never asked for (I have not imported any of my SSH keys to FileZilla). After a few failed authentication requests (due to non-matching keys), the server drops the connection. My log (edits are marked <like so>):

Starting filezilla as

SSH_AUTH_SOCK= ./filezilla

works around this issue.

1. In the Miscellaneous settings dialog the text 'Adjust these values if you get very slow transferrates' should read 'Adjust these values if you get very slow transfer rates'.

2. In the Miscellaneous settings dialog the text '.......buffer size carefully, too high.....' the text should read '.....buffer size carefully. Too high....' (The comma should be replaced with a full stop, then a new sentence started).

Hello:

I tried to upload a number of files into a server through FileZilla by clicking a file, then Shift Click that resulted in a selection of 11 files. Then, I drag & drop the files to the server file list.

Opted to overwrite the existing files > Always use this action > Apply to current queue only.

All the 11 transfers then failed.
