the exercise. • Use technology (slides, demos, and guided lab exercises) in the most appropriate ways depending on the audience profile and their comfort with Ubuntu. • Use presentation slides to stay Source and Linux There is often confusion between open source, free software and Linux. While all three are inter-linked, there are distinct differences which are made clearer when looking at their evolution Term Support (LTS); it was released in June 2006. Long-term support version refers to guaranteed three years of support on the desktop and five years on the server. All other releases are provided with

The main commercial The next step in the installation process is to decide how you want to update the system. There are three options: • No automatic updates: this requires an administrator to log into the machine and manually from a terminal: sudo tasksel install dns-server 10 Installation 4. Upgrading There are several ways to upgrade from one Ubuntu release to another. This section gives an overview of the recommended upgrade

triangles means that you have two windows of the same app open. If you have three or more windows of the same app open, three triangles will show. Apps that aren't currently running have translucent mouse pointer over any point on the scrollable edge of the content to reveal the thumb slider. Ways to use the scrollbars: Click the top half of the thumb slider to scroll one page up. Click the network menu on the menu bar and uncheck Enable Wireless. What do WEP and WPA mean? WEP and WPA are ways of encrypting data on wireless networks. Why does my wireless network keep disconnecting? You might

guides for installations on: • s390x LPAR • z/VM • ppc64el Create a bootable USB There are many ways to boot the installer but the simplest and most common way is to create a bootable USB stick to boot bootloader (Petitboot, a small linux kernel) from a “PReP” partition with a special flag, so in most ways they are similar to a UEFI system. The installer only supports one PReP partition at this time. Limitations (a.k.a. d-i). Autoinstalls for the new server installer differ from preseeds in the following main ways: • The format is completely different (cloud-init config, usually YAML, vs. debconf-set-selections

Debian Reference 7 / 238 • All fully-qualified filenames begin with the ”/” arguments. 1.2.3 Filesystem permissions Filesystem permissions of Unix-like system are defined for three categories of affected users. • The user who owns the file (u) • Other users in the group which • Type of file (first character) • Access permission of the file (nine characters, consisting of three characters each for user, group, and other in this order) • Number of hard links to the file • Name

user-friendly software packages. The community has categorized its software repositories into three types based on the source, quality attribute, and package maintenance mode. You can configure services. • NAS is often deployed in the public zone, and accessing it from the host requires crossing three layers of networking. If one end is faulty, the IP address cannot detect the fault. File systems FS6 IP network FS File sharing Virtualization Container Compared to native NFS, eNFS boasts three key innovations. • It enables second-level failover in the event of software or hardware faults on

SLOC for each of several programming lan- guages considered, etc. In the following sections these three steps are described in more detail. 3.1 Which source code makes a Debian release? The Debian packaging be built automatically from each source package. For instance, from a certain source package maybe three different binaries packages are built: one with a library, another with and executable program and build the binary package). Then, the source package is built, usually (but not always) consisting of three files: the upstream sources (a tar.gz file), the patches to get the Debian source directory (a diff

ready to go, you should first make sure that tftpd is enabled. In the case of tftpd-hpa there are two ways the service can be run. It can be started on demand by the system’s inetd daemon, or it can be set boot parameters for either the installer or the kernel, press Tab (BIOS boot), or e then down arrow three times then end, to edit the “linux”line of the boot entry (UEFI boot). This will bring the boot command e (language), debian-installer/country (country), debian-installer/locale (locale) There are two ways to specify the language, country and locale to use for the installation and the installed system.
