    Hello,

    I am getting emails from my server that someone is trying to brute force into my server...but APF and BFD are holding and they seem to blocking the IP's.

    Is there anything i can do about these brute force attacks ?

    What can i do ?

    Thanks.

    what do you want to do more ? The system detects and bans.... all is done, you can't go to the other person and break down his server/computer ...... :cool:

    Well, you can report the offender to the appropriate law enforcement officials.

    In the meantime, be glad that they can't access your box!

    change SSH from port is possible but believe me useless

    hackers use prt scans and they will just go over each and every port so if you move it from 22 to 65000... in the end they'll scan it and try

    and you would have to change many things so your server continues to work.

    Your firewall works as it should

    Just get used to get several mails a day with warnings and the fact it added the 'nasty' ip to it's deny list

    Not much more you can do except as said above, take note of the iP and complain but.... if the origin is like India, Russia etc, good luck. Won't be very usefull

    so read all security related topics and learn to close at best your server for nasty attacks etc. And be prepared to close gaps from time to time. Keep all up to date and read and learn.

    search for the IP owner from which you are attacked. From the details, you can email to their abuse email if listed. But most IP owners could not be bother with taking actions of these hackers. But some does do something about these hacker. That's as much as you can do. Just be glad that you had BFD to block them.

    you need to unblock the port in APF config

    change where it is 22 to the new port number into your APF config.

    then restart apf

    also restart ssh after change the port in ssh config file.

    if all gone and you cant access you have 2 options, use telnet or call your ISP

    or if you do have physical touch with the machine go to it and check those info here.
