  • OpenSSL Essentials: Working with SSL Certificates, Private Keys and CSRs | DigitalOcean – OpenSSL is a versatile command line tool that can be used for a large variety of tasks related to Public Key Infrastructure (PKI) and HTTPS (HTTP over TLS). This cheat sheet style guide provides a quick reference to OpenSSL commands that are useful in common, everyday scenarios. This includes OpenSSL examples of generating private keys, certificate signing requests, and certificate format conversion. It does not cover all of the uses of OpenSSL.

  • Security Tips for Apache Web Server – Debian-based Systems – Apache is one of the most widely spread Open Source web server for web hosting in Internet due to its stability, robustness and rich variety of modules and features. Due to its popularity, Apache comes with pre-build binary packages for almost all major Linux distributions and can also be installed on other Operating Systems such as Unix, Windows, Mac OSX, BSD etc. However, a basic installation of Apache on Linux systems, by default, doesn’t offer a full protection against attackers, so a few security measures must be taken in order to protect your machines, web servers and web documents against such types of malicious attacks. This article will provide you a few tips on how you can secure and protect Apache Web Server installed on Debian-based Linux distributions.

  • A Visual Git Reference – This page gives brief, visual reference for the most common commands in git. Once you know a bit about how git works, this site may solidify your understanding.
  • SSH_VPN – Community Help Wiki – This page discusses using SSH to set up SSH-based point to point connections, which can then be used to create routes that create virtual private networks. Note that using SSH in this fashion is not the "best" way to create a permanent, stable VPN. Notably, SSH uses TCP, and TCP over TCP can provide abysmal performance under pathological conditions.
  • VPN over SSH – This how-to is intended to cover the details of how to establish a VPN (Virtual Private Network) over a SSH connection. Starting with open-ssh 4.3, you can now use a ssh connection to set up a VPN. This is technically termed "layer-3 IP-in-SSH tunnelling" and is not using ssh to port forward (ssh -L ) or create a dynamic "application level" forwarding (SOCKS) (ssh -D ). Rather a VPN is established using a SSH connection to create a virtual interface, tun0. Advantages : IMO, this technique is easier to set up then openvpn, especially if you are using a single client. Works with most Linux distributions without the need to install any additional software on the clients. The server only needs openssh-server. This protocol uses udp to transmit tunneled tcp connections resulting in a more stable connection compared with port forwarding (using ssh with the -L or -D options). Disadvantages : As of yet I do not know of a windows client which will use this protocol. If you are needing to set up a VPN with numerous clients I would use openvpn. Although there are several "how-to's" on the web, most of them assume you know something about networking and routing. This page attempts to explain some of the "missing details".
