Basic Commands for Using pure-ftpd

Now that you’ve got pure-ftpd installed, it’s time to start working with it. Let’s begin by looking at some basic commands that are frequently used to manage your FTP server.

1. Starting the FTP Server

To start the pure-ftpd server, simply run the following command:

sudo systemctl start pure-ftpd

This will launch the FTP server and begin accepting connections on the default FTP port (21). If you want the server to automatically start on boot, you can enable it with:

sudo systemctl enable pure-ftpd

2. Stopping the FTP Server

If you need to stop the FTP server for any reason, you can do so with the following command:

sudo systemctl stop pure-ftpd

Stopping the server may be necessary when performing maintenance or making configuration changes.

3. Restarting the FTP Server

If you’ve made changes to the server’s configuration and want to apply them without fully stopping the service, you can restart it with:

sudo systemctl restart pure-ftpd

4. Checking the Status of the Server

To check if the pure-ftpd server is running, you can use the status command:

sudo systemctl status pure-ftpd

This will give you a status report indicating whether the server is running or if any issues need to be addressed.

Advanced pure-ftpd Commands and Configuration

Now that you know how to manage the server, let’s take a look at some advanced features and commands you can use to customize and secure your FTP server. With pure-ftpd, there are a wide range of options available to help you fine-tune your setup to fit your needs.

1. Configuring Anonymous FTP

By default, pure-ftpd allows for both authenticated and anonymous FTP connections. If you want to enable or disable anonymous access, you can edit the configuration file located at:

/etc/pure-ftpd/pure-ftpd.conf

Look for the line containing AllowAnonymous and set it to yes or no depending on your needs. If you want to allow anonymous FTP access, set it to "yes" and restart the server:

AllowAnonymous yes

sudo systemctl restart pure-ftpd

2. Enabling SSL/TLS Encryption (FTPS)

Security is always a top priority, and pure-ftpd supports FTP over SSL/TLS (FTPS) for encrypted file transfers. To enable SSL/TLS, you’ll need to generate an SSL certificate and update the configuration file.

To generate a self-signed certificate:

openssl req -x509 -newkey rsa:4096 -keyout /etc/ssl/private/pure-ftpd.key -out /etc/ssl/certs/pure-ftpd.crt -days 365

Then, enable SSL/TLS by editing the configuration file and setting the following options:

TLS               yes
TLSCipherSuite    ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH

Restart the server to apply the changes:

sudo systemctl restart pure-ftpd

3. Limiting User Access

In many scenarios, you may want to limit user access to certain directories or restrict the number of simultaneous connections. You can set up user-specific directories or configure the maximum number of connections in the configuration file.

For example, to limit users to specific directories, you can set up a chroot jail in the configuration file:

ChrootEveryone    yes

This will confine all users to their home directories and prevent them from accessing other areas of the file system.

4. Logging FTP Activity

For monitoring and troubleshooting, it’s often helpful to enable logging. You can configure pure-ftpd to log all FTP activity. To enable logging, open the configuration file and set:

SyslogFacility    ftp

This will log FTP activities to the system log, which you can review for any issues or track usage patterns.

pure-pw userdel
