What are the advantages of using Mepis?

Mepis is an operating system, based on Linux. The advantages of Mepis compared to other Linux distributions are its lightness, its stability, and its simplicity of use.

What is an inode number in Linux?

An inode is a data structure on a traditional Unix-style file system such as UFS or ext3. An inode stores basic information about a regular file, directory, or other file system object.

Each and every file under Linux (and UNIX) has following attributes:

* File type (executable, block special etc) * Permissions (read, write etc) * Owner * Group * File Size * File access, change and modification time * File deletion time * Number of links (soft/hard) * Access Control List (ACLs)

All the above information is stored in an inode.

So, each file has an inode associated with it and an unique number called inode number.

This number is used to look up an entry in the inode table.

Compaq evo t30 wince net 16 nand 32 ram can i put tiny core Linux on this and how do i do it will upgrade ram?

Yes, it is possible to put Tiny Core Linux on it. The procedure to install it (or any other operating system) involves making an adapter for the hard drive in the Evo and connecting it to another computer. This will involve extensive soldering skill.

Which version of Linux supports IPv6?

All versions of the Linux kernel since 2.0 support IPv6. Most modern distros have IPv6 enabled, but as there are over 300 different distributions, it is impractical or impossible to list all of them.

How do you switch from the X server to a terminal in Linux?

Simply pressing Ctrl+Alt+F3 (or one of the other function keys will switch you to a terminal where you can log in and perform work. Depending on your distro, the X server is already running on one of the terminals; just press Ctrl+Alt and one of the function keys until you find it to switch back. On Ubuntu and Debian, this should be F7.

What is the special software used in Linux to open an audio file?

There is no specific or singular program in Linux to "open an audio file." Just as in Windows, there are a large variety of media players to choose from. These include Amarok, Rhythmbox, Juk, VLC, MPlayer, Banshee, and Audacious.

Are there computer forensic tools available for Mac OS and Linux similar to Hex Workshop?

For the Mac there are numerous tools available. Macs come with a set of developer tools that, when installed, offer tools and utilities for assorted tasks. Depending what you are trying to achieve OxED or Hex Fiend (See links below) may be adequate.

If you download Linux on your Mac will it take over Mac OS and is there any way to avoid that without partitioning the HD if it does?

If you download Linux to your mac, nothing will happen until you initiate the installer. If you want to install Linux but keep Mac OS also installed, you will need to partition your hard drive. This can be done using the Disk Utility application that is found in the Utilities folder of Application. Finder > Applications > Utilities > Disk Utility

How do you remove write protection from a partition running Windows that's missing the hal.dll file and the rest of the partitions are running Linux?

If you are talking about accessing the partition from Linux, the kernel file system driver does not allow writing to NTFS partitions. You can write to the partition in Linux if you install the NTFS-3G file system. This is the only form of "write-protection" that should be on your system.

What is n command in Linux?

There is no "-n" command by default in linux, though it can be an option to other commands. For example, in the make(1) command, it can be used to suppress the make program from actually doing the actions specified - it just prints out what it would have done.

Answer

[-n] may be what is called a "switch" typically passed to a Unix or Linux command. As mentioned above, it modifies the actions of another command. For example, in the sort(1) command, it instructs sort to sort numerically instead of alphabetically. The meaning of any given switch will typically vary from command to command so read each man page carefully before using a switch. [JMH]

How do you install Xfce in Damn Small Linux?

It is not possible to install Xfce on Damn Small Linux without extensive modification. Damn Small Linux uses a very crude Xserver that is not capable of rendering Xfce. Also, the versions of several libraries needed for Xfce are too old. It would be far easier to start of with a distro that supported Xfce from the start, like Xubuntu.

How can you know the IP address of the computers connected to a server in Linux?

Depending on what kind of server it is, connections can be very transient. The 'netstat -nat' command should print out a list of current TCP connections.

How format a PC to run only Linux?

Putting a password on your bios will prevent anyone but the user from running the computer let alone installing another operating system. Can't think of any other way to prevent operating systems from being installed/used. Encrytped hard drives can be formatted. Password protected bootloaders don't prevent other systems from being installed.

What is the purpose of the POSIX operating standard?

POSIX is a IEEE standart family with the puprpose of maintaining compatibility between operating systems. It defines command line shells, utility interfaces and the application programming interface. It is most commonly applied to Unix based operating systems, such as the various Linux distributions or MacOS.

How do you get album information from a CD on Linux?

The Album information is stored in the metadata of the audio files on the CD. When you rip the CD, the information is usually transferred automatically.

What software does not support Linux?

There are thousands of pieces of software in existence. It would be impractical, if not impossible, to list every piece of software that was not compatible with Linux.

What was in the letter that linus torvalds sent to the unviersities?

A 1500 line commands that create in c++.this is the first Linux operating system made by linus torvalds for the purpose of teach the students only.

What steps can you take to find a printer driver that isn't included with a Linux distribution?

An enlightened printer manufacturer my have a Linus/Unix printer driver available for the printer (Apple's OS is build on top of Unix!) so look on the manufacturers web site. [HP provides open source drivers for most of their printers as part of the HPLIP project. ]

However in general the Open Source model does not approve of proprietary printer drivers and the Linux way is to provide generic printing capability using what is called the Common Unix Printing System (CUPS - see the related link below). This means that even though you can not find a specific printer driver for your printer you Linux system may still detect it and use it - try using the printing tools.

----

CUPS includes drivers for Dymo, Epson, HP, Intellibar, Okidata, and Zebra printers.

-----

Photo-quality printer drivers are available for Canon, Epson, HP, and others from the Gutenprint open source project.

Why some of popular operating system are not support for posix compliant?

Without getting into too much detail, it's largely a choice made by developers of the system whether or not providing a POSIX-compliant or at least POSIX-compatible system is worth the effort.

The aim of POSIX is not to be a standard defining operating systems themselves so much as standard for a suitable environment for source compatibility between different operating systems, primarily those of a Unix-compliant or Unix-like design. I believe full POSIX compliance is a requirement of the Single Unix Specification in turn, the SUS being a standard that actually DOES define what an operating system should be (In this case, to be considered a real UNIX system. Needless to say Windows is nowhere in the neighborhood of SUS compliance.).

The idea behind POSIX is to make it much easier for Unix/Unix-like software developers to write software and have it available for those who provide selections of software for any given Unix platform. Program written for POSIX OS A can be built for POSIX OS B with little or no changes to the source code of the program, usually the only changes needed are bits closer to the metal or usage of libraries not concerned with POSIX compliance.

POSIX does not concern itself or define any standard for binary compatibility. This is not just a matter of scope but the fact that such an application of the standard would only be useful on OS-to-OS ports of a program being made on the same system architectute, which would make POSIX less useful for Unix systems, which are frequently deployed in mixed-architecture environments.

Windows has a POSIX layer available as a download, but generally it's a limited, only halfway-compliant POSIX system. Windows itself is not designed in a way that is generally POSIX-compatible, since it's software architecture is a fundamentally very different thing from Unix. For most Windows users and developers: POSIX compliance is of very little practical use, as Windows' design still requires some very POSIX-unfriendly additions to source code to build correctly on Windows. For Windows to become a POSIX system would require Windows itself to be completely remade in ways that breaks all backwards compatibility with previous versions of Windows, something most users would not like. When open source software is ported to Windows, one generally uses MinGW or tools like cmake that provide build scripts/files for POSIX and non-POSIX systems alike.

How do you install Kubuntu on your computer from a CD?

Installing Kubuntu from a Kubuntu LiveCD is a fairly straightforward process.

To install Kubuntu, first boot from the CD. Your computer's BIOS may attempt this before booting from the hard disk drive, or prompt you to boot from CD. If not, access the boot menu by pressing Delete or F12 or whichever key your computer says, systems differ.

Next, when the computer boots from the disc, you will be prompted to select a language within a time period, usually 30 seconds. The default selection is English. Then you will see the CD menu. You may boot Kubuntu by selecting "Try Kubuntu without making changes to your computer" or install immediately by selecting "Install Kubuntu". If you choose to try Kubuntu, you can select the Install icon on the desktop.

Kubuntu will then run the install wizard. Follow the instructions to install Kubuntu. You will need to select your language, keyboard layout, and choose a location (for time zone). Your exact location may not be an option on the map, select the nearest city or one in your time zone.

Before the install wizard makes any changes, it will ask you which disk to install to, and whether to use the entire disk or use a smaller partition. If you don't want to permanently delete your existing data and operating system, let the installer resize your existing partitions and make a new ext3 or ext4 Linux space. After this, the installer will make its changes and create the files. This will take about 10-30 minutes, depending on your hardware.

Once the install is complete, your computer will be restarted. Boot into Kubuntu and set up your internet connection, download any drivers needed (such as nVidia or ATI video card binary drivers), and software updates (using your package manager, either Adept or KPackagekit).

One other note, if you have a new computer and intend to have Kubuntu AND another operating system (such as Windows) installed, install the non-Linux operating system first, as it may not allow you to set up partitions on your hard drive(s).
