Enable cPanel DAV Hidden:
Before you start adding CalDAV you have to initially enable cPanel DAV hidden by whm.
Steps to enable cPanel DAV Daemon:
Step 1: Go to WHM and log in to your account.
Step 2: Contact the Service Manager by searching in the search box
Step 3: Click on Enable and Monitor for hidden cPanel DAV settings.
Now that you have enabled cPanel DAV you will then need to open ports in the firewall to allow connection to cPanel DAV settings
At first you should learn some information about opening windows with the firewall >> This is necessary when you enable cPanel DAV hidden settings to manage connections by default. The process of opening ports to the firewall is simple and you can easily implement them whether you use APF or CSF
Identify the firewall used:
If you are using the default configuration of a VPS server or you are using a dedicated server, you are using APF and to do so, please follow the steps below.
Run the following command as root:
/ bin / systemctl status apf.service
root@hostname ~ $ /bin/systemctl status apf.service ● apf.service - SYSV: Advanced Policy Firewall Loaded: loaded (/etc/rc.d/init.d/apf; bad; vendor preset: disabled) Active: active (exited) since Wed 2017-10-04 17:51:10 EDT; 2min 37s ago Docs: man:systemd-sysv-generator(8) Process: 20628 ExecStart=/etc/rc.d/init.d/apf start (code=exited, status=0/SUCCESS)The output confirms APF activation
If the output appears this way
root@hostname ~ $ /bin/systemctl status apf.service
Unit apf.service could not be found.
It means that the APF signal is not active
If not activated, the following root is used
/ bin / systemctl status csf.service
That means it works with CSF
root@hostname ~ $ /bin/systemctl status apf.service ● csf.service - ConfigServer Firewall & Security - csf Loaded: loaded (/usr/lib/systemd/system/csf.service; enabled; vendor preset: disabled) Active: active (exited) since Wed 2017-09-20 13:58:36 EDT; 2 weeks 0 days ago Main PID: 829 (code=exited, status=0/SUCCESS) CGroup: /system.slice/csf.service
Steps to Open Ports Using APF:
Step 1: Run the following command
nano /etc/apf/conf.apf
Step 2: Specify the following code:
# Common ingress (inbound) TCP ports
IG_TCP_CPORTS = "20,21,25,53,80,110,113,143,443,465,993,998,2049,2077,2078,2082,2083,2086,2087,2089,2095,2096,3306,5222,9090,12001"
Step 3: The second line of code will be released to enter ports 2079 and 2080 and so will be
# Common ingress (inbound) TCP ports
IG_TCP_CPORTS = "20,21,25,53,80,110,113,143,443,465,993,995,2049,2077,2078,2079,2080,2082,2083,2086,2087,2089,2095,2096,3306,5222,
Step 4: Restart the APF again through the apf -r command
Steps to Open Ports Using CSF:
Step 1: Run the following command:
nano /etc/csf/csf.conf
Step 2: Identify the following code:
# Allow incoming TCP ports TCP_IN = "20,21,25,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096"
Step 3: Edit the code to enter ports 2079 and 2080 and thus will become
# Allow incoming TCP ports TCP_IN = "20,21,25,53,80,110,143,443,465,587,993,995,2077,2078,2079,2080,2082,2083,2086,2087,2095,2096"
Step 4: Restart the CSF again with the csf -r command
