    i have got cPhulk unabled for the bruteforce attacks and set the limit to 5 per IP and per account... to try reduce the amout of attacks people do ... but in the last like 24 hours i have reived about 12-15 emails about brutforce attacks detecked all from diffrent IPS every time i click black list everytime as well... i dont want to block the whole contry ect... and i dont know what to do

    can anyone give me any advice?

    i am root on the server and every singl attempt is trying to hack the root account...


    is there anyway i can allow only MY ip to connect to the root account and any others get black listed?

    If this is sshd or WHM, you can use WHM > Security Center > Host Access Control to allow only your IP(s) and block all others without them having to be blacklisted. Something like the following would work:

    Code:
    Daemon 	  Access List   Action 	  	Comment
    sshd 	  YourIP1 	allow 	  	Allow my IP for SSH
    sshd 	  YourIP2 	allow 	  	Allow my IP for SSH
    sshd 	  ALL 	  	deny 	  	Deny other IPs for SSH
    whostmgrd YourIP1 	allow 	  	Allow my IP for WHM
    whostmgrd YourIP2 	allow 	  	Allow my IP for WHM
    whostmgrd ALL 	  	deny 	  	Deny other IPs for WHM

    If you only whitelist (allow) your IP for sshd in Host Access Control and deny all other IPs, no-one else but you can even reach sshd anyway. It would work better than changing the port.
