Troubleshooting users and file transfers

Analyzing log files is the most important technique for troubleshooting all kinds of problems or improving services on Linux. In this recipe, you will learn how to configure and enable vsftpd's extensive logging features in order to help system administrators when problems arise, or simply to monitor usage with this service.

Getting ready

To complete this recipe, you will require a working installation of the CentOS 7 operating system with root privileges and a console-based text editor of your choice. It is expected that your server will be using a static IP address and that vsftpd is already installed with a chroot jail and is currently running.

How to do it...

1. To do this, log in as root and type the following command to open the main configuration file in your favorite text editor:

   vi /etc/vsftpd/vsftpd.conf
   

2. Now, add the following lines to the end of the configuration file to enable verbose logging features:

   dual_log_enable=YES
   log_ftp_protocol=YES...
