Based on the information from the website www. Let's get started with the setup. The ZFS file system is a revolutionary new file system that fundamentally changes the way file systems are administered on Unix-like operating systems. ZFS provides features and benefits that were not found in any other file system available today.

ZFS is robust, scalable, and easy to administer. There are many reasons for this such as program accessing partition or open file , but the most important one is to prevent the data loss. All you have to do is stop vi process and run umount again. As soon as that program terminates its task, the device will no longer be busy and you can unmount it with the following command:. The following discussion allows you to unmount device and partition forcefully using mount or fuser Linux commands.

Please note that using these commands or options can cause data loss for open files; programs which access files after the file system has been unmounted will get an error. I migrated fully to NIX after years as a Win admin and got tired of having control "hidden". Worked with ESX and used the console and loved the freedom.

Keep It Simple Stupid is something Nix should be doing, having things modular and not depending on something else makes life easier. If one thing breaks it's not taking everything else with it.

This is also akin to making your browser part of your OS and having it intertwine with it. Bad Voodoo I'm using Mint and looking for a possible way to decouple from systemd. Now is the time to deviate from systemd and keep a more modular approach then watch and see if systemd starts to be an issue, which at this point if it keeps taking over more management it's only a matter of time. I like improving things, but this does not appear to be an improvement rather a bomb waiting to go off.

On these points this is a bad idea, binary not an easy way to gain insight and correct issues and adding multiple processes to control with more being added. I was able to patch heartbleed within 15 minutes after finding out about it. I will admit right off, that I am not a linux designer or maintainer. I got started with linux about 20 years ago. People state that the old init system was fragile. Maybe it was, again…not building linux from scratch I wouldn't know.

I don't recall ever having any issues though. Whether right or wrong, from my very limited understanding, the systemd process is driven by binary files, which are not really meant to be edited or looked at by hand.

So if something catastrophic happens which granted hasn't happened yet …how would I fix it or know what to fix? Anyway, if one of the earlier commenters is correct, and there is no specific plan for systemd which frankly is a scary thought …how much more of the system will it continue to take over? And at what point does too much become too much? I'm all for progress, but I think the Keep It Simple Stupid approach, which may not be "exciting" stuff to develop, it still the best approach.

I can't speak for the initial decision, but at this point, I would suspect that inertia is keeping it in place. I highly doubt that any of the major linux desktop systems that must current users depend on would even function without systemd…at least not without a lot of major programming changes to make it happen.

If someone did take that route, then all of those custom changes then need to be maintained. Distro X uses a systemd plugin for their init, and distro Y chooses to build against something else? Granted systemd is most likely now too big for that, but one can dream I suppose. Systemd is a perfect system for rootkits, and NSA backdoors.

Once it will be complete it will hide necessary processes even from root, it will filter unnecessary events from log, and it will do much much more. IMHO, the downside of systems as a project is that its parts lack a defined stable interface.

This means that you cannot replace one part with a different one, creating your own stack of tools. When you configure your desktop system, you can combine any display manager with any window manager with any panel or file manager. Can you replace networkd with another tool transparently? If yes, can you be sure that your tool will keep working after the next systemd upgrade?

The reason Debian and therefore Ubuntu adopted SystemD is that the appointed Debian tech team is now devided equally between Ubuntu devs which were Debian devs before Ubuntu came along and Redhat employees. Look at the voting emails and 3 months of arguments.

The biggest issue is really not one of SystemD infiltration, but more of Redhat taking over every aspect of the Linux development process. Time and again, I have seen Canonical steer in their own direction, not because they want too go rogue, but because the upstreams for the main projects Gnome, Wayland, Pulse Audio, now SystemD and possibly OpenStack, and even the kernel to some extent are almost exclusively owned by Redhat, and only wish to make forward progress at their own pace wayland has had almost twice the development time and resources as mir for example.

Do some real investigation and write a story on that. Systemd, the binary, handles service management in pid1, that includes socket and explicit activation. Other tasks it passes off to non-pid 1 processes. For example: Network configuration got added in networkd. What is networkd? The most minimal network userland you can have. Its for people who don't want to write by-hand config files, but for whom NetworkManager is way overkill.

Is it pid 1? Yes, systemd started off as "just an init replacement. But don't assume that "systemd" the binary is the same as "systemd" the project. Most things that are added to systemd in recent times AREN'T pid 1 like boycottsystemd claims, they're just small utilities that got added under the systemd umbrella project. People talk as though prior to systemd such tasks were beyond Linux, didn't work, always crashed, were a nightmare to use or manage and that is not the case.

The only difference I see between my Linux machine now and my Linux machine of a few years ago is that it now boots faster. And that's it. And whilst that's nice, it's so meaningless as to be painful to behold the enthusiasm that some display, as though all they did all day long was sit and reboot their machines with a stop watch in one hand. The main problem with systemd is this — if there are ulterior motives at work here and by definition they will be hidden at present then by the time we find that out it will be too late.

I do wonder how far systemd would have got had it not had Red Hat's weight behind it. I do realise that improvement sometimes means kicking out old 'tried and trusted' methods.

But it's the way its happening with systemd that rings alarm bells — too many sneering, nasty bullies trashing anyone who disagrees just like anyone who thinks Corporations should pay proper taxes is sneered at, or anyone who thinks Putin is not as bad as he is made out to be gets sneered at — sneering is the new way of silencing genuine debate, so when I come across it in Linuxland, alarm bells beging to ring. Just read http: It includes parallel versions of ssh, scp, and rsync, as well as a parallel kill command.

He is every bit a nerd, but can be candid, though precise. Both recent innovations that have come from SUSE - patching a live kernel, technology called kGraft, and creating a means for booting openSUSE on machines locked down with secure boot, have been his babies.

Will it ever be the year of Linux on the Deskto Score: Be careful what you wish for.

Systemd, for or against? This is pretty important to the community here and probably the first question that needs to be asked before any others. Because x86 doesn't have the system management chip that Unix boxes full disclosure, old AIX admin, last used 5. This also what allows hot cpu, hot ram upgrades etc.

A sysadmin can use it to wipe out and reinstall the server's OS and perform firmware upgrades without even walking into the server room. I've submitted several bug reports, with some including patches to fix the problem. They all get ignored for a very lon g time, if not forever.

Up-to-date information is available online: Thus it is needed to transform sysconfig settings to avoid potential data loss or unwanted misbehavior. The following variable are affected:. If this setting is in place, that means that no ordinary user can use crontab. Looks like in their infinite wisdom SLES developers introduced group trusted as if allow and deny files are not enough. By default group trusted has no members, but what is interesting that adding user say oracle to this group did not solve the problem for me.

The SLE 11 SP3 kernel contains a fully supported ext4 file system module, which provides read-only access to the file system. A separate package is not required. Most server hardware clocks are use UTC.

Other time zones are determined by adding or subtracting from the UTC time. Server typically displays local time, which now is subject of DST correction twice a year. Wikipedia defines DST as follows:. Daylight saving time DST , also known as summer time in British English, is the convention of advancing clocks so that evenings have more daylight and mornings have less.

Typically clocks are adjusted forward one hour in late winter or early spring and are adjusted backward in autumn. Please see this wikipedia article. If that was not the case, the DST change needs to be made manually.

The tzdata package contains data files with rules for various timezones around the world. When this package is updated, it will update multiple timezone changes for all previous timezone fixes. These zoneinfo files, part of the timezone package, are not human-readable. To check the data in them, use the zdump command. For example,. At the time it was said the change was needed to encourage contributions from a wider set of developers, and Ruby is said to be simpler and more flexible.

Well, today Jos Poortvliet posted an interview with two YaST developers explaining the move in more detail.

In a discussion with Josef Reidinger and David Majda, Poortvliet discovered the reason for the move was because all the original YCP developers had moved on to other things and everyone else felt YCP slowed them down.

We even did our custom builds of openSUSE No more major changes are planned for this development cycle, but the new Yast will be used in See the full interview for lots more detail. Support for the btrfs File System. Btrfs is a copy-on-write CoW general purpose file system.

Based on the CoW functionality, btrfs provides snapshoting. Beyond that data and metadata checksums improve the reliability of the file system. On appropriate storage devices btrfs also supports the TRIM command. Each file system offers disctinct advantages. While the installation default is ext3, we recommend xfs when maximizing data performance is desired, and btrfs as a root file system when snapshotting and rollback capabilities are required.

Btrfs is supported as a root file system i. YaST will prepare the btrfs file system for use with subvolumes and snapshots. Snapshots will be automatically enabled for the root file system using SUSE's snapper infrastructure. Migration from existing "ext" file systems ext2, ext3, ext4 is supported "offline" and "in place". Calling "btrfs-convert [device]" will convert the file system.

Roll back: Btrfs is supported on top of MD multiple devices and DM device mapper configurations. Please use the YaST partitioner to achieve a proper setup. Check and repair functionality "scrub" is available as part of the btrfs command line tools. The tool "fsck. If you are planning to use btrfs with its snapshot capability, it is advisable to reserve twice as much disk space than the standard storage proposal.

This is automatically done by the YaST2 partitioner for the root file system. A temporary limitation of this approach affects the number of hard links in a single directory that link to the same file. The limitation is dynamic based on the length of the file names used. A realistic average is approximately hard links. When using character file names, the limit is 14 links. We intend to raise the limitation to a more usable limit of links in a future maintenance update.

Read-Only Root File System. A read-only root setup consists of the read-only root file system, a scratch and a state file system. The quickest way to build a commercial Linux business is to clone whatever Red Hat does. The company could have spent a lot of time and money creating a tool that allowed for the management of RHEL and SLES, the two most popular Linuxes in terms of support revenue, not necessarily installations.

The code behind Red Hat Network Satellite, the version of Red Hat's management system that you run behind your own firewall as distinct from plain old Red Hat Network, which Red Hat runs on its systems to manage yours from outside your firewall was open sourced in June Red Hat's Enterprise Linux distro uses Yum for package management and Kickstart for network installs.

Novell has added support for Zypp and AutoYast their equivalents to Spacewalk 1. But Jarvis says that these ZENworks products were designed at first to control Windows-based desktops and use terminology and logic familiar to Windows admins, not to Linux nerds. But the problem is larger than that. Linux people want open source tools, Windows people could care less. Linux and Windows platforms are like Hatfields and McCoys in the data center. They may share the same kind of iron most of the time, but even with virtualization on the rise and presumably making them share virtualized platforms under a single management framework, they tend to be siloed and they take shots at each other - mostly verbally - over the racks from opposite sides of the data center.

Novell tried to ignore this fact, as have Red Hat and VMware. They probably won't mind using a clone of RHN Satellite painted green with chameleons crawling all over it, though. SUSE Manager is available today and is open source, so you don't have to pay to use it.

But if you want the supported version, which gets patch feeds from Novell and Red Hat for their respective Linuxes, then you have to pay some cash. The product has five different components. You can manage virtualized versions of those Linuxes running locally on your own iron as well as out on public clouds; SUSE Manager can also be used, just like RHN Satellite, to patch and provision those Linuxes on bare physical iron in a non-virtualized manner. Then, on top of this, you have to buy management, provisioning, and monitoring modules to provide the functionality that you want.

But if the management tools are essentially the same, now Novell at least stands a chance of winning some RHEL takeout deals. FileMirrors for DVD. OpenSuse Documentation.

Access the Command Line Interface From the Desktop A classic multiuser environment can be implemented by connecting several terminals dialog stations —monitor and keyboard units—to the serial interface of a single computer.

You can also connect several terminals to the serial interface in a Linux system. However, because more than one person often uses the same PC, virtual terminals were created in Linux. With virtual terminals, you can work in Linux as if you had several classic terminals available at the same time. You can have up to six virtual terminals F1-F6 running on your computer.

You can determine the terminal currently being used from the tty number tty1—tty6. When you switch to a virtual terminal, a login prompt appears: Besides using the virtual terminals, you can start a terminal emulation from your GNOME desktop by selecting Gnome Terminal shown in the following picture or X Terminal from the main menu. Both belong to the System application group. The terminal opens inside a window with options you can select to modify the display of the terminal such as font and background color.

You also log in and log out at a virtual terminal. Use the Linux Desktop Summary Objective 1. With Gnome Terminal you can access the command line interface within an window. There are many modules for all important configuration tasks available but in this section you will only learn about the network configuration module and the software module as examples.

The YaST user interface can appear in two kinds: Text mode QT. To start it. You are asked to enter the root password. Fully graphical mode The appearance of the user interface depends on which command you use to start YaST and on whether you use the graphical system or the command line. To start the ncurses interface of YaST. Figure You control the ncurses interface with the keyboard.

After entering the root password. Except for the controls and the appearance. You can list the available YaST modules with the command yast -l or yast --list. To select a menu item. To start an individual module. To go back to the previous box. Mark highlighted menu items by pressing the Spacebar.

Figure Press Tab to move from one box to another or to the text buttons. Use the arrow keys to navigate within the box. You can often press Alt and the highlighted letter to access an item directly. When you finish making changes with a YaST module. From here you can select a category on the left such as Software or System and a module on the right such as Online Update to configure and manage your system.

The package is installed directly without any dialogs. To display a list of YaST options. In other cases there is an additional intermediate step.

Sometimes YaST writes the configuration changes you make directly into the final configuration file. Some of these variables are used directly such as in some start scripts. This is where the program SuSEconfig becomes important.

Other variables are used to modify other files. For this reason. To activate the network configuration module. Traditional Method with ifup. The traditional method uses the command ifup. We recommend you to use this setup method. Use a desktop applet that manages the connections for all network interfaces. Figure YaST wants to know the network setup method: Usually the cards are autodetected by YaST.

Figure Select the card you want to configure. Some kernel modules can be configured more precisely by adding options or parameters for the kernel.

Select Add. Under Kernel Module. Details about parameters for specific modules can be found in the kernel documentation. A Manual Card Setup dialog appears: You can select the card model from a list of network cards. Each computer in the network has at least one address for each network interface. Figure From this dialog you enter the following information to integrate the network device into an existing network: According to the currently valid standard IPv4.

If you choose this option. Static address setup. In this case.

Computers in the network can be addressed directly using their IP addresses or with a unique name. The network mask referred to as subnet mask in YaST. The mask divides the IP address into a network section and a host section. All computers within the network can reach each other directly without a router in between. Domain Name. If you only want to change other information you can select Accept here. Figure This dialog lets you enter the following: IP number. This is the name of the DNS domain to which the computer belongs.

Domains help to divide networks. Enter a name with which the computer can be addressed. All computers in a defined organizational area normally belong to the same domain. This name should be unique within the network. This consists of the host name and the name of the domain. The domain search list specifies the domains with which the system can expand the host name to the FQDN.

If the computer is intended only to reach other computers in the same subnet. Domain search list. To address other computers in the network with their host names. This complete name is then passed to the name server to be resolved. In the local network. If the search list contains several domains. You can specify a maximum of three name servers. This name is then passed to the name server to be resolved. Separate the domains with commas or white space.

You can create entries in the routing table of the system after selecting Expert Configuration. The following appears: Figure You can define the following: Enable IP Forwarding.

All data not addressed to the local network is then forwarded directly to the gateway. If the network has a gateway a computer that forwards information from a network to other networks.

If you select this option IP packages that are not dedicated for your computer are routed. In the General tab of the Network Address Setup dialog. Administer Linux with YaST All the necessary information is now available to activate the network card.

Possible values are: De- activate the firewall for the interface. If activated. During system start Version 1 Copying all or part of this manual. Three zones are possible: Choose when the interface should be set up. You can verify this with the command ip.

Two network devices are always set up by default-the loopback device lo and the device sit0 NONE. After you save the configuration with YaST. If there is a physical network connection. To allow this for normal users activate the option User Controlled. The size depends on the hardware Ethernet: When the hardware is plugged in.

On Hotplug. In this exercise you have to change all the important information into static values. To do this. The installed packages and the packages that are available on the installation media are analyzed and dependencies between packages are checked. The following filters are available: Figure To help you find the software you want to install. After this checking. Displays all language related files e. Displays all software that is available on the known installation media.

Package Groups. It is grouped in predefined sets of packages that logically belong together. Displays all the packages with a marked status.. Installation Summary. Lets you enter a search term and where you want YaST to search for the software package. Lists all registrated installation sources and displays the available packages of this source.

It is grouped by category. You might see a dialog indicating that the dependencies between the packages cannot be solved and that some other packages need to be installed. The most commonly displayed symbols include the following: Figure To view a list of all possible symbols.

In most cases you can simply confirm this dialog. The installation state is shown by a small symbol in front of the package name. Select the symbol of the package you want to install several times until the Install symbol appears. To edit the configuration of an existing installation source. Figure To add a new source. If you want to add more installation sources.

Depending on the type of source. To change the order of a source in the list. To remove an installation source permanently. YaST uses the first installation source in the list that has the software package you want to install. Available modules can be listed with the command yast -l or yast --list.

The ncurses interface is controlled exclusively with the keyboard. YaST can be controlled intuitively with the mouse. You can verify this with the command ip address show. There are dependencies between the packages. Otherwise they must be resolved manually. The installation status of a package is indicated by a symbol. In most cases these dependencies can be resolved automatically. The following details are then needed to integrate the network device into an existing network: Manage Installation Sources Summary To add a new installation source.

This section shows you how to find and use several sources of help information. All manual pages are available in English and many have been translated into other languages. Because these translations are often incomplete or not maintained. For example to display the English version of the man page for the command man.

The manual pages are always divided into parts and arranged according to various sections. To start the online help. If you install them manually. Locate and Use Help Resources Objective 5.

Find Help on the Web Summary The Internet is a very extensive source of expert knowledge for general issues and special issues with Linux. The following are a few of the more commonly-used web sites: But if you exchanged data with people in other countries using other settings. You can also use umlauts. A filename in Linux can be up to characters long. To understand the concept of the Linux file system. If you want to use one of these characters without the associated special meaning.

Linux differentiates between upper-case and lower-case letters. The following is an extract from a typical file system tree: Figure A file in this directory tree is uniquely defined by its path.

It can stretch over several partitions. A path refers to the directory names which lead to this file. It begins at the root. The path can be specified in two ways: This tree is not limited to a local partition. The length of the path cannot exceed characters. Sometimes it is necessary to specify the absolute path because certain files can only be uniquely addressed in this way.

It will be explained later in detail. The FHS does not specify all details. As a second layer. This book is beneficial for the beginner users. The contents are written in simple and easy to understand format, mainly keeping in mind about the newbie Linux users who have come from other OS or just have installed any Linux Distros for the first time. The first chapter of this book has focused on the traditional history of Unix, Linux, Users Interface, features of Linux, and the various desktop environment.

Then you will be getting quickstart documentation on initial setup, login, password, GUI, Command Line Interface, files management, and necessary Linux command. In the third chapter, you will be able to play with the Linux files system and partitioning. The fourth chapter will allow you to learn about various processing task related to users, Boot, Grub, and Multi-tasking inside out.

Moreover, it gives detailed information about Desktop environment, Graphical User interface, Shell Script, and setup, X window system and configuration, keyboard, date, language and fonts set up, installing software, and package management.
