Why might one administrator choose one Linux filesystem over another?
Oh, various reasons. Each filesystem has its strengths and weaknesses. Some handle lots of read/write operations more efficiently than others, some deliver in speed, others handle great big files and others handle very small ones.
Who are the co founders of Linux?
There are no co-founders of Linux. Linus Torvalds created it alone, however, after some time more and more people joined the core development
What can be used on Linux to provide file and print services?
CUPS is the de-facto network print service for Linux and Mac. Certain windows versions can connect to it also (unless you have XP home or some other crippled version)
Native Linux file transfers might occur over
HTTP (Web server)
FTP (FTP server)
scp (ssh server)
NFS (NFS 'network file system' server)
SAMBA (Samba file and print service for Windows, also works as a client for win servers)
Of the five, NFS is probably the preferred Linux file server (especially in a Linux/mac/Unix only environment), because you can mount the server directory on the client and it will appear as a local directory.
For true compatibility with windows, there is one answer to both questions:
SAMBA.
Samba uses the same Small Message Block (SMB) protocol that is native to Windows clients. It is a Linux and Mac implementation of NetBios, NT File Server, NT Print Server, and Active Directory server and client all rolled into one.
How can I connect to a wireless network using command line in Linux?
Connecting to wireless is a somewhat different beast than connecting to wired networks because there are several extra aspects to the connection. The following instructions will walk you through 1) making sure your drivers are correct, 2)Connecting to the AP, 3)Joining the IP network.
First things first, make sure that you can turn on the wireless interface, which might be named wlan0, ath0, or some other convention. If you can, then you have properly installed wireless card drivers. If you can't, then you might have to install drivers, firmware, or both to get it working.
ifconfig wlan0 up
Next, the configuration of all the wireless configurations is done using the iwconfig command. Using that tool, you can enter the SSID, Access Point MAC address, etc. Usually specifying the SSID is sufficient. To see a list of available SSID's to connect to, use iwlist, then configure your interface like so:
iwlist wlan0 scan
<produces a list of various SSID's along with their Access Point, frequency, encryption type, etc.>
iwconfig wlan0 essid "MyNetworkSSID"
Check the current configuration of your interface like this:
iwconfig wlan0
If your interface has joined with the access point, you will see all the configuration information here.
Now, your network HOPEFULLY has some sort of encryption. For that, you will need to install wpa_supplicant. The configuration here can vary from one distribution to another, but basically it will store encrypted network keys for various SSID's. If you use encryption you will have to use it, but I'm not going to explain how to set it up as it may be different on your distribution.
All of that just registers you with the Access Point. Now you can finally set your IP address either by setting it manually or obtaining it through DHCP.
Manually:
ifconfig wlan0 192.168.1.100
or by DHCP
dhcpcd wlan0
or
dhclient wlan0
What Linux operator causes the output to be appended to an existing file?
This operator also exists in Windows as well. The operator is >>.
Most Linux distributions are already secure. It would actually be more difficult to make them"unsafe."
What is the overall role of Linux and what does it allow the user to do?
The overall role of Linux is to provide a Unix like Posix compliant kernel that when used in conjunction with other software and packaged into a "distribution" (eg. Debian, Gnewsense, Ubuntu) provides a complete operating system environment that can be used on a variety of different processors.
In other words, a GNU/Linux distribution allows the user to do everything you would expect an Operating System to do, as well as provide all the applications that a user would need to use to accomplish tasks on a computer (eg. web browsing, email, word processing, spreadsheet calculations, database formulation, archiving etc.)
Because Linux and the majority of the other software found in most distributions is licensed under the GNU Public License, a user can expect to have the freedom to do the following:
This is in stark contrast to most proprietary software which generally restricts your usage of that product to usage deemed acceptable to the owner of the software (ie the software company) through End User License Agreements, most of the terms of which most users do not read and do not understand.
What web servers are available for Windows?
There are several major web servers available for Windows:
What file system has a theoretical partition size limit of 16 exabytes?
NTFS provides a 64-bit disk addressing scheme
It's a command to start the X server for running Linux in graphical mode, if you have any of the desktop environments and/or window managers installed.
What is the cost to purchase a Linux license?
Nothing. The GPL is not a license you purchase.
It is legal to sell Linux distributions, but most (Except for Red Hat Enterprise and a few others.) don't cost a thing and are free to download.
How much money does Linus Torvalds have?
Linus Torvalds was worth approximately $20 million in 1999. No doubt the value of the stock he owns has gone down, but it is safe to say that he is still a millionaire.
Dependency has nothing to do with where the files are located. Most programs in Linux share libraries, and place the libraries under a separate directory for organizational purposes. Sure, you could place a copy of the library under each program's directory, but this wastes space and defeats the purpose of shared libraries in the first place. ALL operating systems that use shared libraries, including Windows and Mac OS X, require dependency tracking for proper operation. The only way this could be eliminated is if we all went back to static binaries instead.
How do you access slave hard drive in Linux?
Big chance that is on /dev/sdb
if no then try /dev/sdc and /dev/sdd
to mount em do in terminal:
su
(you password)
mkdir /mnt/slave
mount /dev/sdb /mnt/slave
change as you like
you drive will be accessible in /mnt/slave folder
How do you get and install Linux Mint while using Linux Ubuntu?
1. download and burn the setup media
2. meanwhile backup your home directory (including the hidden folders)
3. install Linux mint
4. extract the backup to your home folder
Further to above:
When installing Linux Mint from the CD (iso), the Ubuntu already on the hard-drive will be automatically detected. You will be asked whether to install Mint alongside Ubuntu, so creating a dual-boot, or use the entire hard-drive for Mint alone, so wiping Ubuntu off the hard-drive.
If you do create a dual-boot system, on booting the computer you will have the choice on using either Mint or Ubuntu.
What are Linux download packages called?
They're collectively called packages, unless if you are referring to manually-downloaded compressed TAR archives, which are commonly referred to as tarballs.
What command do I use in Linux to list all absolute path names in my current working directory?
ls -la
"ifconfig" is a command found in most *NIX operating systems (think UNIX, Linux, BSD, etc...). it's equivalent in Windows is "ipconfig". it is a command you call from the shell (not the graphical user interface) that allows you see/set IP configurations for a specific interface.
What is Linux Hosting and where can you get more information about it?
Linux hosting involves hosting your website on a Linux based server in order to make use of additional coding and programing not available to other operating systems. You can find more information about Linux hosting at the Webhosting Top website.
What is Larry the Cow's relationship to Linux?
Larry the Cow is the unofficial mascot of Gentoo, a semi-popular Linux distribution.
What are binary files and libraries in Linux?
Binary files are compiled programs. Libraries are external resources that one or more programs can call upon to aid them in a task.
How about the process scheduling for time sharing processes in Linux?
Most UNIX based Operating systems use a "time slice" method of scheduling. A ready process will operate for it's allocated time slice, then be put on the "ready queue" and the scheduler will first attempt to find the next ready process of highest priority to execute. It may be the same process again if no other process of higher priority is ready. Ready implies that the process is not waiting for resources and is not waiting for a timer or other interrupt. When a process has run until it is no longer ready, it is put on the queue along with a list of resources or interrupts that it needs.
How do you create a file in Linux with write-only permissions?
Create a file and set it's permissions to 222
What are compression and archiving commands in Linux?
tar cvf archive.tar *.txt
will create an archive called archive.tar with all the .txt files in the current directory.
tar cvzf archive.tar.gz *.txt
will create a compressed archive called archive.tar.gz
What are some software that can be run on Linux wine?
Linux wine allows the user to run Windows software when they are using a Linux operating system. One would like to do this if they like how Windows software works rather than the Linux equivalent, for example some people like Microsoft Office products.
