Users Guide

As consecutive login failures accumulate from a specific IP address, they are tracked by an internal counter. When the user logs
in successfully, the failure history is cleared and the internal counter is reset.
NOTE: When consecutive login attempts are refused from the client IP address, some SSH clients may display the following
message:
ssh exchange identification: Connection closed by remote host
.
NOTE: IP blocking feature supports upto 5 IP ranges. You can see / set these only via RACADM.
