          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd

        ReportedBy: sworddragon2 at aol.com


I see every few days in the process list that somebody is trying to
connect to my server every second. I have a good password and such a
brute force attack is nearly impossible but I want some more security.

For example an option that blocks an ip address for a specific time
after a few amount of fails. Another example is that we can allow ssh
connections only every few seconds from a client. All these values
should be configurable.
