    I seem to be getting quite a number of these of late.
    Dropping connection from xx.xxx.93.23 because of tcp_wrappers at cpsrvd.pl line 4191.

    I know that this is someone trying to log in to cpanel.
    However, is it a cpanel account or my WHM account.

    Even though Host Access control appears to be stopping them, they keep coming back and trying, so i'm manually adding them to CSF.

    Hello :)

    There are no native features that will tell you if it's cPanel or WHM, but you could run tcpdump when this happens to see if increased activity occurs over specific ports. EX:

    Code:
    tcpdump -n dst port 2087
    Thank you.

    I take it TCPDUMP has to be run whilst the login attempt is in progress ?
    If this is the case, then it's unlikely that i'll catch it.

    Yes, that is correct. It's likely more useful if your system is constantly under brute force attacks and you want to see the specific activity on a port.

    Thank you.
