SUMMARY Dolphin prematurely attempts to connect to SFTP server for each value of the address field while the user is in the process of editing it. For example (and how I noticed), I had an SFTP address loaded but realized I wanted to log in under a different user, so I selected the username (preceding "@" in the URL), typed the new username, and pressed enter. By then the server had blocked my IP address because of too many failed login attempts (it's using fail2ban). I was able to check the auth.log file afterwards, and it had this sort of thing logged from the sshd process: Invalid user s from XX.XX.XX.XX port 53XXX Invalid user sh from XX.XX.XX.XX port 53XXX error: maximum authentication attempts exceeded for invalid user s from XX.XX.XX.XX port 53XXX ssh2 [preauth] Invalid user sha from XX.XX.XX.XX port 53XXX Invalid user shar from XX.XX.XX.XX port 53XXX ... Is this maybe triggered by a path completion feature being too eager? STEPS TO REPRODUCE 1. Connect to SFTP server. 2. Edit user name in address bar. OBSERVED RESULT Observe logs of each keypress causing a login attempt on the server. Or a temporary ban, depending on how the server is configured. EXPECTED RESULT No such spurious attempts in the server log, no temp ban. I would think Dolphin should wait until the URL (or at least the username+domain part?) is complete/ENTER is pressed before attempting to log in.
