It kind of looks like when connecting to an SFTP server using public key authentication, FileZille cycles through all of your keys trying all of them until it finds the correct one. I've got like a dozen OpenSSH powered servers under my control, all of them with public key authentication, and this feature has caused some of them to raise a "Too many authentication failures" error.
The only solution I've been able to come across was to raise the MaxAuthTries value to something higher than 12, which doesn't seem reasonable.
If you're connecting via SSH with OpenSSH, you can do:
Code: Select all
Host example.com
IdentityFile /example/com/id_rsa
Host foo.com
IdentityFile /foo/com/id_rsa
