cPHulk Management on the Command Line

Today, let us see the methods used by our Support techs to manage cPHulk.

Enable cPHulk

To enable cPHulk, you can use the following methods:

• Firstly, WHM’s cPHulk Brute Force Protection interface (WHM >> Home >> Security Center >> cPHulk Brute Force Protection).
• From the command line, run the WHM API 1 enable_cphulk command:

  whmapi1 enable_cphulk

Enable and disable debug mode

To enable debug mode, perform the following steps:

1. Firstly, create the debug touch file in the /var/cpanel/hulkd directory:

   echo 3 > touch /var/cpanel/hulkd/debug

2. Then, restart cPHulk:

   /usr/local/cpanel/scripts/restartsrv_cphulkd

To disable debug mode, perform the following steps:

1. Remove the debug touch file:

   rm /var/cpanel/hulkd/debug

2. Then, restart cPHulk:

   /usr/local/cpanel/scripts/restartsrv_cphulkd

Check cPHulk’s status

To check the status of cPHulk, perform one of the following actions:

• Call WHM API 1’s cphulk_status function.
• Then, run the following command:

  ps aux | grep -i cphulk

  The system will return output that resembles the following example:

  root 1501 0.0 0.4 34816 5076 ? S 07:58 0:00 cPhulkd - processor

  In this example, the output indicates that cPHulk is enabled.

Restart cPHulk

To restart cPHulk, perform one of the following actions:

• Call WHM API 1’s configureservice function. This also rebuilds and restarts Dovecot. To do this, run the following commands:

  1 2	whmapi1 configureservice service=cphulkd enabled=0 monitored=0 whmapi1 configureservice service=cphulkd enabled=1 monitored=1

• Perform a soft restart. Then, rebuild and then restart Dovecot. To do this, run the following scripts:

  1 2 3

  /usr/local/cpanel/scripts/restartsrv_cphulkd /usr/local/cpanel/scripts/builddovecotconf /usr/local/cpanel/scripts/restartsrv_dovecot

• Perform a hard restart and force the system to flush the service’s memory. Then, rebuild and restart Dovecot. To do this, run the following commands:

  1 2 3

  /usr/local/cpanel/scripts/restartsrv_cphulkd --stop; /scripts/restartsrv_cphulkd --start /usr/local/cpanel/scripts/builddovecotconf /usr/local/cpanel/scripts/restartsrv_dovecot

Disable cPHulk

To disable cPHulk, perform one of the following actions:

• Firstly, call WHM API 1’s disable_cphulk function.
• Call WHM API 1’s configureservice function. For example:

  whmapi1 configureservice service=cphulkd enabled=0 monitored=0

• Then, run the following commands:

  1 2	/usr/local/cpanel/etc/init/stopcphulkd /usr/local/cpanel/bin/cphulk_pam_ctl --disable

Keep cPHulk offline

To disable cPHulk so that it remains offline, even after a restart of cPanel & WHM, perform the following steps:

1. Firstly, remove the enabled touch file:

   rm /var/cpanel/hulkd/enabled

2. Edit the /etc/dovecot/dovecot.conf file to remove the following line:

   auth_policy_server_url = http://127.0.0.1:579/dovecot-auth-policy

3. Then, rebuild Dovecot’s configuration file. To do this, run the following script:

   /usr/local/cpanel/scripts/builddovecotconf

4. Restart Dovecot. To do this, run the following script:

   /usr/local/cpanel/scripts/restartsrv_dovecot
