You can use the useradd or usermod commands to add a user to a group. The useradd command creates a new user or update default new user information. The usermod command modifies a user account i.e. it is useful to add user to existing group. There are two types of group. First is primary user group and other is secondary group. All user account related information is stored in /etc/passwd, /etc/shadow and /etc/group files to store user information.

useradd Example – Add A New User To Secondary Group

You need to the useradd command to add new users to existing group (or create a new group and then add user). If group does not exist, create it. The syntax is as follows:

useradd -G {group-name} username

In this example, create a new user called neo and add it to group called matrix. First login as a root user (make sure group matrix exists), enter:

grep matrix /etc/group

About vsftpd

The first two letters of vsftpd stand for “very secure” and the program was built to have strongest protection against possible FTP vulnerabilities.

Step One – Install vsftpd

You can quickly install vsftpd on your server in the command line:

sudo apt-get install vsftpd
Once the file finishes downloading, the VSFTP will be on your server. Generally speaking, it is already configured with a reasonable amount of security. However, it does provide access on your Server to anonymous users.

Step Two – Configure vsftpd

Once vsftpd is installed, you can adjust the configuration.

Open up the configuration file:

sudo nano /etc/vsftpd.conf
The biggest change you need to make is to switch the Anonymous_enable from YES to NO:

anonymous_enable=NO

About SSL Certificates

A SSL certificate is a way to encrypt a site’s information and create a more secure connection. Additionally, the certificate can show the server’s identification information to site visitors. Certificate Authorities can issue SSL certificates that verify the server’s details while a self-signed certificate has no 3rd party corroboration.
