For security reason, in shared hosting account allow_url_fopen is disabled by default. If you want to enable this function, you need to modify the custom php.ini file.
allow_url_include:
This functions is also disabled and to use allow_url_fopen you need to turn on this function too in the same way as allow_url_fopen.
Steps to enable allow_url _fopen and allow_url_include functions:
Step 1: Create a custom php.ini file in your public_html folder
Step 2: Add these two lines in your php.ini file to enable these functions:
allow_url_fopen = on
allow_url_include = on
Save the file and you are done.
Steps to disable allow_url _fopen and allow_url_include functions:
Step 1: Create or open the custom php.ini file in your public_html folder
Step 2: Add these two lines in your php.ini file to disable these functions:
1) Add cpcalendar, cpcontacts, mail and webmail A records pointing to your sever’s IP. make sure the Procy Status (Cloud) is OFF (DNS only)
2) Once this records are properly set up, back in cPanel we will open SSL/TLS Status, here we will generate an Auto SSL, but before remove any subdomains that are not going to be used.
For example if your domain is hosted somewhere else remove the main domain and the www subdoamin. you might find some weird addresses like www.domain.mailserver.com, you can also Exlude those before running the AutoSSL.
3) Once you have excluded all the unwanted addresses, click Run AutoSSL, this might take a while depending on how many domains you have so, prepare a coffee and sit tight.
If everything went well you will see green locks next to all your addresses:
4) Now we are ready to use the secure connections provided by Cpanel, go to Email Accounts -> and select the desired account and click on Connect Devices. There you will see all the necessary information to connect suing SSL/TSL
Many times we have a website but we are not using our domain to create email addresses. If that is the case the domain main A record is already pointing to a server where the website is hosted.
If you want to setup emails for your domain in a different server, there a few things that need to be done on the DNS. For this tutorial we will use cloudflare as our DNS manager, and a cPanel server as our mail server.
1) Add the doman to your server, in Cpanel this is done in the Domain Addons section. Simply add the domain. assign a subdomain and a path, cPanel will suggest one for you so you can go for that.
2) Identify the IP of your server because we will use it to set up a few records on the DNS, in Cpanel go back to the home page and it will be located on the right side
3) Next we need to add a few records to cloudflare so we can connect our domain to the server and also make to the have the right configuration for email deliverability. (Avoid Spam Box).
We will add 4 A records: mail, cpcontacts, cpcalendars, and webmail, all with the same IP address that we got before, make sure the cloud is turned off if using cloudflare. (cpalendars and cpcontacts are optional and used only if you will synchronize calendars and contacts).
Once all 4 are added it will look like this (plus any other records you might have):
Then we need to go back to Cpanel and get information about the DKIM and SPF records, these are standard records to ensure Email Deliverability and do not end up in the Junk mail.
4) In Cpanel look for Email Deliverability and click on manage next to your domain.
If you notriced Cpanel had a warning “Problems Exist (DKIM and SPF)” this is because we need to install the records on the DNS.
5) Copy the Name and Value for the DKIM TXT record and paste it in Cloudflare as TXT records. Do the same for the SPF record.
In Cloudfalre:
Once Both records are installed they will show like this
To make sure that the records were well instaled, we can go back to Cpanel and open again the Email Deliverability, if we have a VALID notification, then we successfully installed the records.
If you got to this point you have successfully setup the records and now you are ready to create new email accunots
6. From Cpanel, go to Email Accounts -> Create and select your domain, then assign a username, a password and a Storage Space. about 5Gb should be enough to start with.
To change the port for the SSH server, follow these steps:
Log in to the server as root using SSH.
Open the /etc/ssh/sshd_config file in your preferred text editor (nano, vi, etc.).
Locate the following line:
Port 7822
Remember that for security reasons, A2 Hosting uses port 7822 for SSH connections instead of the default port 22.
Change 7822 to the new port number that you want to use.
Save the changes to the /etc/ssh/sshd_config file, and then exit the text editor.
Restart the SSH service using the appropriate command for your Linux distribution:
For CentOS and Fedora, type:
service sshd restart
For Debian and Ubuntu, type:
service ssh restart
While still logged in as root, in a new terminal window try to log in using the new SSH port number. If the login fails, check your settings. Do not exit your open root session until you are able to log in using the new configuration.
You can use find and locate commands in Linux to find folders and files from the command line. This page shows how to search for folders in Linux using various command line utilities.
Command to find a folder in Linux
find command – Search for files and folder in a directory hierarchy
locate command – Find files and folders by name using prebuilt database/index
How to find folder on Linux using find command
The syntax is:
find /where/to/look/up/ criteria action
find /folder/path/to/look/up/ criteria action
find /folder/path/ -name “folder-name-here”
find /search/path/ -name “folder-name-here” -print
find /search/path/ -name “folder-name-here” -ls
find /folder/ -name “pattern”
Finding a folder named Documents
Example : find /home -name “phlox-pro”
To find a folder named “Documents” in your home directory ($HOME i.e. /home/vivek/ home directory), run:
find $HOME -type d -name “Documents”
OR
find ~ -type d -name “Documents”
OR
find /home/vivek/ -type d -name “Documents”
How to search for case incentive folder names
You can force find command interpret upper and lowercase letters as being the same. For example match Documents, DOCUMENTS, DocuMEnts and so on by passing the -iname option:
find $HOME -type d -iname “Documents”
