![]() ![]() Certificates issued by a proper certificate authority such as Verisign or Thawte are impossible for forge, because they have been signed by the authority's master certificate. Typically the server sends its certificate to the client to prove its identity, so that the client knows that its connection to the website has not been re-directed by an attacker. Most modern Linux distributions include SSL support in their Apache package as standard though.Īt the heart of the SSL protocol are digital certificates, which are used for both authentication and encryption. The *Configuring Apache as a proxy server* section explains how to check for and possibly enable the mod_proxy module, and you can follow those same instructions for mod_ssl as well. However, this depends on having the mod_ssl Apache module compiled in or available for dynamic loading, which is not always the case. You can configure Apache to use HTTPS on a per-virtual server basis, or to use it for all servers. Almost every browser supports the HTTPS protocol, and uses it when retrieving URLs that start with instead of the normal Whereas the normal HTTP protocol use TCP port 80, the HTTPS protocol uses port 443. The result is a new protocol called HTTPS, which is used by all websites that want to operate securely. However, in this chapter we are only concerned with the encryption of web page requests and responses, which is done by encrypting HTTP protocol data with SSL. The SSL protocol can be used to encrypt any kind of data that would normally travel over an unencrypted TCP connection. It also allows clients to authenticate themselves to servers, which can be used to replace usernames and passwords with digital certificates. It allows servers to authenticate themselves to clients, so that a web browser can be sure that it is connecting to the website that is thinks it is. It encrypts network traffic, so that an attacker cannot listen in on the network and capture sensitive information such as passwords and credit card numbers. Now I can sleep well at night.SSL is a protocol for making secure, authenticated connections across an insecure network like the Internet. Now go to Webmin is now accessible securely by typing your domain name into the browser. Add your domain name into the "Hostnames for certificate" box. Go to Webmin ConfigurationĬlick SSL Encryption. Here are my commands for my Ubuntu Xenial VM with Apache: $ sudo apt-get install software-properties-common $ sudo add-apt-repository ppa:certbot/certbot $ sudo apt-get update $ sudo apt-get install python-certbot-apache $ sudo certbot -apacheįollow the instructions on-screen to receive a free cert. Make sure that you have completed this before going on to the next step. Let's Encrypt do not issue certs for IP addresses. ![]() Make sure that the A record of your domain name's DNS points to the IP address of your server. At this point, you should still be logged in to your server through SSH. Let's Encrypt, in their own words, is a free, automated, and open certificate Authority. Your ID is root and your password is what you just set. SSH into your server and run passwd to change your root password: $ passwd ![]() If you are like me and have been talking to your server through Google's browser's based SSH shell, then you don't have a password. Webmin asks for your username and password. To access webmin, go to Your browser detects that you are trying to access webmin securely without a cert. Edit your firewall rules in Google Console to accept connections from port 10000. deb sarge contribĪdd Webmin's GPG key to apt so that your Linux server will trust it: $ wget -q -O- | sudo apt-key add -įinally, install Webmin: $ sudo apt-get install webmin ![]() In nano or your editor of choice, go right to the end of your sources.list file to include Webmin's repository. Edit your source list: $ sudo nano /etc/apt/sources.list Give my VM its own domain name - GoDaddy sells them cheap for the first year.Webmin is free and received a nice face-lift recently. I lived through the command-line era of MS DOS in the 80s and 90s but like most people, have long gotten used to the point-and-click interface. As I start to call GCP home, it's time to dress it up. Thanks to Google Cloud Platform's free tier and $300 credit, I have been spending more time building on GCP. ![]()
