Once I've obtained free SSL certificates from Let's Encrypt, preferrably wildcard ones, as described in another article here at Mimar - Let's Encrypt Wildcard Certificates On FreeBSD With BIND DNS Validation - I'm going to combine them into single PFX file so it can be used by Microsoft Exchange to secure IMAP, SMTP, POP and IIS services.
The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks. It has many well known security issues, and nowadays shouldn't be used at all. However, all Microsoft Windows versions from last two decades ship with PPTP client included which makes it very convenient. As of OpenBSD 5.3, npppd – New Point to Point Protocol Daemon – became a part of OpenBSD base system. The following article describes how to configure it as a PPTP server which authenticates users from RADIUS.
Desktop environments on FreeBSD are usually started by some kind of display manager, such as GDM or KDM. This is specially true for "heavy" desktops such as GNOME or KDE, which are almost impossible to run without one. On the other side, "lighter" desktops such as Xfce run just fine without a display manager. Steps to start Xfce without login manager are described in FreeBSD Handbook, but they require user to log in and start X server manually. The following article describes how to start Xfce automatically immediately after user logs onto local console.
Default FreeBSD installation will boot into command line login prompt, requiring users to log into the system before gaining access to the programs, which is usually done by typing username and password interactively. In some cases, however, we want to login certain user automatically on boot. Steps to accomplish this task are described in the following article.
