    Hello:

    I'm trying to change my VPS provider, for this, yesterday i bought a new VPS in other provider that use OpenVZ.

    Then I installed a clean "CentOS 6 64 bits" image from the VPS control panel and installed WHM-Cpanel using the commands: wget -N http://httpupdate.cpanel.net/latest - sh latest

    I finished the installation, and then the configuration in the web interface (choose default daemons, IPs and nameservers and turn on CPHulk with default options).

    Few minutes later i can't enter my VPS with root password in WHM or SSH. I can enter to WHM web interface to login and in SSH I try to enter as root but the password is refused and says "access denied". I'm pretty sure that my password is correct.

    I try to connect using local machines (same IP) and using other virtual machines off this lan, to check if is a firewall problem and give me the same error "access denied".

    I try to recreate other root password in VPS interface but didn't work too.

    I'm pretty sure that I'm not being blocked by the firewall because I can send and receive PINGs and the SSH connection actually works but it refuses my password.

    Is the second time that i suffer the same, the other time provided a VPS with KVM virtualization and have the same sintoms. Other virtualization and other provider, same problem, I not persisted the last time.

    Do you have any idea about this issue?

    Thanks.

    Hello :)

    It's possible the "root" user was locked out by cPHulk brute force detection:

    "WHM Home >> Security Center >> cPHulk Brute Force Protection"

    It's documented here:

    cPHulk Brute Force Protection

    This includes instructions on how to whitelist your IP address and how to disable cPHulk via the command line.

    Thank you.

    Hello CpanelMichael:

    The problem is that CPHulk don't blocked my IP, i can access the login, but the user ROOT is disabled or blocked, the user, not my IP. I can login as root in SHH but refuse my password.

    When suffered the issue, i try to connect in my home, and then use VPN and other virtual machines with others IPs to connect but all refuses the ROOT password. I think that disable the user ROOT for all IPs, no a specific IP... if possible that a system blocked ROOT user, not a specific IP or range of IPs, don't see the logic because can't access in WHM, SSH o serial console to disable CPHulk or whitelist my IP (is not listed before).

    If possible that issue, have any solution to avoid that the ROOT user to be blocked?

    Thanks.
