    The first set of logs is just cPanel (specifically chkservd I think) checking the FTP daemon to make sure it's alive and functioning. Nothing to worry about.

    The second one I think is probably an attempt ot log in via SSH by a particular IP address. Look at other log entries with the same/very close timestamp on them for your answer. Probably SSH, but could be some other service that uses PAM for authentication. At any rate, other entries directly above and below the '580 LOGIN DENIED' will give you your answer regarding what service was targetted, what IP address was blocked, etc.

    All those lines with logins to 127.0.0.1 did scare me a little but that's understandable.

    It is correct that service monitoring through "chkservd" connects from localhost, via the loopback IP address of "127.0.0.1" -- this is normal; also to note, the log file for chkservd is located at the following path where logged information may be cross-referenced:
    Code:
    /var/log/chkservd.log
    Regarding cPhulkd, to help locate additional details I would consider checking the cphulkd log file at the following path:
    Code:
    /usr/local/cpanel/logs/cphulkd.log
    For additional documentation about cPHulk I recommend the following resource: Use cPHulk for Brute Force Protection
