  • How to Disable Strict Host Key Checking in SSH – TecAdmin

    The SSH server has default enabled the strict host key checking. When the key checking is enabled, the SSH client connects only those hosts, that valid host keys are stored in the known host’s file. You can find the fine at ~/.ssh/known_hosts.

    Once you are connected to a remote host file time via SSH, the SSH clients check for the host key file under the known_hosts file. If the key is found, you will be connected to a remote server after authentication, but if key doesn’t found in the known_hosts file, the command will show a warning message and a prompt to accept or reject the connection request. Once you accepted the by typing “yes”, the key is added in the known_hosts file.

    Here is an example to of command:

    ssh ubuntu@remote-host
    Output

    The authenticity of host 'remote-host (123.45.67.89)' can't be established.
    RSA key fingerprint is 9f:48:89:f5:68:2f:cd:b3:19:95:40:43:98:09:0a:1a.

  • 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.
