  • How To Secure FTP Server With SSL/TLS In Rocky Linux | LinuxTeck

    In this article, we will demonstrate how to configure a Secure FTP server (vsftpd) using SSL/TLS encryption. Traditional FTP services are not very secure and vulnerable because the credentials are transmitted in clear text, which is prone to crackdowns and many types of attacks like brute force. The majority of applications these days come with a security feature that can be used to set up a secure FTP server. Consider encrypting data between the Server and Client with FTPS (FTP Secure) in conjunction with SSL/TLS. SFTP (SSH File Transfer Protocol) is another way of securing data transmission. SFTP was developed as an extension of SSH, and it can also be used with other security protocols.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
