NB: This tutorial assumes that you have already installed proftpd on your system. If you have not Click on this link on how to do so
roFTPD (Pro FTP Daemon) is an FTP (File Transfer Protocol) server for Unix-like operating systems. It serves as a software solution to enable file transfers between computers over a network, typically the internet.
Navigate to the directory where you extracted the proftpd archive. For me, this was “/root/Downloads/proftpd-1.3.8a/”.
Run the configuration script that checks for the kernel, compiler and other requirements. I have used the command
./configure
--enable-shadow
--enable-autoshadow
--enable-openssl
--with-openssl-cmdline=/usr/bin/openssl
--with-modules=mod_tls
.
This time the configuration script is made to enable the use of open ssl and includes the tls module.
Compile the proftpd daemon using the “make” command.
Install the proftpd daemon using the “make install” command.
Open the proftpd.conf using the command “vim /usr/local/etc/proftpd.conf”.
Add the IfModule section in the “proftpd.conf”. Some of the key options include;
This directive turns on the TLS (Transport Layer Security) engine, enabling SSL/TLS support for ProFTPD. When TLSEngine is set to "on," ProFTPD will attempt to negotiate secure connections using SSL/TLS.
This directive specifies the path to the log file where TLS-related log messages will be written. It's helpful for troubleshooting and monitoring SSL/TLS connections.
This directive specifies the TLS protocol version to be used. In this example, it's set to SSLv3. You can adjust the protocol version based on your security requirements and compatibility with clients.
This directive specifies the path to the RSA certificate file used for the SSL/TLS connection. The certificate file contains the public key and other information about the server. Replace /path/to/ftp.cert.pem with the actual path to your SSL/TLS certificate file.
This directive specifies the path to the RSA private key file associated with the certificate. The private key is used for decrypting incoming secure connections. Replace /path/to/ftp.key.pem with the actual path to your private key file.
