OpenBSD is known as the most secure operating system on the planet. The operating system has been developing by a team led by Theo de Raadt (previously one of the core team of NetBSD). The main focus of the OS is security and code correctness with quality documentation. With the detailed documentation, users can easily install and master the OpenBSD operating system as a server, router, firewall, VPN or other purposes.
You want to run XWindow (Xorg) rather than command line on OpenBSD. Here are the trick.
It should be also applicable for every system running Xorg as the X server like Linux, FreeBSD, Opensolaris, etc.
You want to install OpenBSD additional packages such as bash, pico, mozilla-firefox and others directly from an ftp server meaning that you do not need to download the packages first and save to your hard disk. In other word, installing the packages on the fly.
It is very easy to do this. We will do this using ‘pkg_add’ tool. One thing you need to know is ‘pkg_add’ will try to search the packages name in the working directory where you type the pkg_add command and also search the dependency of packages that you want to install. If it could not be found, error messages will be prompted.
