| WinSCP implements two methods for keepalives. For SFTP and SCP, the basic option is to send SSH-level keepalives implemented by null SSH packets (SSH ignore messages). Some servers may be configured not to count these packets as data and thus they will still disconnect clients sending them. Also if you use SSH-1 and your server suffers [[ui_login_bugs#chokes_on_ssh-1_ignore_messages|"SSH-1 ignore message" bug]], this method will not work. | WinSCP implements two methods for keepalives.
