    Hi Harald,

    Thanks for the reply, have already received a number of responses from
    people saying they are getting the same type of probes, as for blocking at
    the firewall, that would definitely be more secure, but unfortunately that
    would add another layer of complexity, so I'm pretty much stuck with use
    strong passwords and read the logs. Talk to you later.

    Regards,
    Dan

    Hi,

    You're not alone :)

    I'm beeing scanned too, from various ip-addresses for various users.

    I guess the solution is to block SSH in your firewall, and open it to
    your needs.
