How do I add an FTP user with a Linux command?

Q. I need to write a PHP script that automatically adds FTP users. I can use the system() function to run a Linux command, but I don't know how to create a new FTP user. Any help here?
I don't own the server, I've purchased a reseller plan.

A. When you say add an ftp user, I assume that you wouldn't want the person to be able to log in to a shell on the system. FTP users are just like any other linux user. Use the adduser(sometimes called useradd) command and pay attention to the --shell switch (set to /bin/false)

how to open a url from linux command line?
Q. I want to run a url from the linux command lline. So, please help me with the command.

A. You could use lynx or links. Both are text-based browsers.

Alternatively, you could use wget which will retrieve the url you pass to it.

How do I edit a text using linux command line mode?
Q. I need to edit a text file but I dont know how do you do it using linux in command line mode.

Thanks!

A. pico or nano are good choices for a novice. emacs or vi for an expert

How do I know which MP3 players can boot a linux live cd?

Q. My current mp3 player cannot be used to boot a linux distro, it seems, after a few approaches.

So, I'd like to know which MP3 players can boot a linux distro when plugged into a PC (live cd).

Even better, how can I tell that an MP3 player is bootable in this way? There seems to be no mention of this possibility in any round-up guides, or in the specs.

A. Some might be able to do micro C linux (uCLinux), but not can boot from any live CD that I know of. Some Tablets with a ARM processor can run Ubuntu, but the isntall is a bit weird. You have to root the device and then write a Ubuntu user space onto the drive, but leaver the kernel and boot loader intact.

RockBox offers OSS firmware that can run on many MP3 players, improving their functionality.

Will all the vista tablet pc components work in XP or ubuntu?
Q. I'm using an HP Touchsmart tx2-1020us tablet pc that runs on vista 64 which it came with. I was wondering if I switched to xp or ubuntu if all off the programs for for handwriting recognition and all the other tablet pc components would still work in either one of them. Basically, I can't stand Vista but I want to keep all the tablet functionality.Thanks.

A. No, they will not work in either XP or Ubuntu.

Linux, I have heard, does have *some* tablet support apps floating around but they are nowhere as comprehensive as what is found in XP or Vista.

MS made many changes to the TabletPC apps in Vista. TabletPC components are now integrated into the Vista OS and are definitely superiors to the XP versions.

In XP, you got WinXP Pro and the TPC components were "shell" apps that ran on top of XP, external to the OS.

On a TPC Vista is definitely the OS to run. Vista is actually quite good. The problem is the third party software developers who have not cleaned up their code to run efficiently or correctly in Vista. And many 3rd party hardware manufacturers have made absolutely horrible device drivers which cause all sorts of problems. I guess that's what you get when you pay someone in Bangalore $1/hour to write your drivers...

And you state you have the 64 bit version as well. Way too many software developers have ignored the 64 bit system and stuck writing apps only for the 32 bit OS. That will be your biggest problem...

If you do want to downgrade to XP Tablet Edition you need to know that XP TE was OEM only. You cannot buy the TabletPC version of XP anywhere except from the manufacturers.

If you're a true geek you can load XP Pro and find all the required apps to create a TPC, but it's a very difficult task to do so. It's much easier to contact HP.

My suggestion would actually be to wait for Windows 7 to arrive and upgrade to it. It will fully support the multi-touch screen on the TX2 which XP will not.

What operating systems are compatible with tablet pcs?
Q. I'm looking to buy a tablet pc on ebay and figure that after i can upgrade the os. I just don't know which ones will be compatible with it.

A. The only OS's that have the complete TabletPC functionality built-in are WinXP Pro Tablet Edition and Vista. And even with these you generally have to have the proper restore disks to prevent digging around the 'net for some device drivers.

There are TabletPC's running Mac OS and Linux, but there is no "package" that loads what you need, You would have to find all the Tablet screen and pen device drivers, all the handwriting recognition software, all the internal server apps, etc yourself to "build" the TPC system.

Vista is a great OS for TPC's, but upgrading to Vista can be problematic as many machines designed to originally run XP won't have the hardware specs to run Vista well. Maxxing out your RAM will help but most TPC's do not have upgradeable video cards.

You'll probably be Ok with anything current from the last 3 - 4 years provided you don't want to run Aero effects, etc in Vista.

How is it I play my windows music in Ubuntu?

Q. I'm a Windows XP user trying to switch to Ubuntu linux for no other reason than to feed my geeky hunger. I don't really play any computer games, so my main concern is how am I supposed to access my gigs of music on my Windows folder from Ubuntu? I only have 2 hard drives (if possible to work on Windows hard drive then great), no jump drives or CDs. Thanks for whatever answers. :)

A. first what type of filesystem on these partitions

look first under places > removable media
if they are there then click on it
it will be mounted to system when you do that
the linux system needs any driver to be attached (mounted ) to it's tree in order to deal with it

if they are not there
then open the terminal (accessories > terminal )
which is a shell emulator (command line interface )
then make the points you want to attach the filesystem to it
"sudo mkdir /media/My1"
where My1 is the name of the mount point to which you will attach your partition
be careful that linux is case sensitive
My_Folder is not thw same as my_folder
then
"sudo mount -t [ntfs,vfat] /dev/sd[a,b..1,2,3..] /media/My1"
you have to choose the filesystem type (vfat or ntfs )
which hard drive sda or sdb
which partition 1,2,3...
if you got an error and the filesystem type is right it will be mostly because of unclean shutdown
if you don't know the dev available
type
"ls /dev/ | grep sd"

good luck

How do I power off / shut down a linux computer?
Q. In windows one simply shuts the computer down and it turns off. How do you do this in linux? So far I have just issued a reboot command and then powered it off after it beeped, but now I want to shut it down remotely. Thank you
How to shutdown now gracefully. Previous power off attempts have not turned off the computer totally.

A. sudo shutdown -hP now

How can I force mount my external HDD in Fedora 10 Linux?
Q. The command line suggested in the error windows doesn't work, and I don't want to have to start Windows just to mount a bloody external. It frustrates me that Linux can't just ignore the fact that there was an unclean shutdown. Windows can handle it, why can't Linux???

A. Could you explain what happens when you try the command line suggested in the error window?
If we knew specifically what the error messages were and the details of what you are trying to do we could help.
If some error messages are ignored and the drive is mounted anyway the problems could become much worse and all data permanently lost.
Good luck

How to remove Linux Mint from my flash drive to install a different distro of Linux?

Q. I installed Linux Mint 10 to my flash drive using the UNetBootin program. I only wanted to give it a test run. Now that I know Linux, I want a different distro. I was just wondering if there was a way to take off the Linux OS from my 4 gig flash drive. Thanks!

A. Which ever Linux you decide on should automatically reformat the flash drive and install itself in place of what was already on the flash drive. If not, you would reformat it with the required Linux partitions and install the new one.

How do I establish a linux operatings system that would be similar to windows?
Q. Linux is free right. So if I have to buy a new hardrive, I won't need windows which is expensive. But how do I know which I should use. There seems to be many different linux operating system.

A. There are many flavours so you need to decide what you want to do with it (use it as a server, as a desktop etc). There are distributions who offer Live CD's. You boot up from a Live CD and are able to test that particular distribution without actually having to install it until you decide it's good for you.

Search on the net for tips about choosing a linux distribution.
http://wiki.linuxquestions.org/wiki/Choosing_a_Linux_distribution

Ubuntu should be good for a beginner.

How can I start Linux and what distribution do you think I should use?
Q. I want to use Linux because I have heard that it is significantly better than IE. My entire family is technologically inept and we only have one computer. How do you think I should start and what distribution do you recommend for a beginner who plans on programming and the like?Any helpful suggestions will be appreciated.

A. I thoroughly recommend two Linux distros.

Linux Mint 9 Main Edition which is based upon Ubuntu 10.04

Linux Mint Debian Edition (LMDE) which is based upon Debian Lenny/Squeeze

Both are easy to install and use plus they come with much of the software you are likely to need preinstalled

HowTo install Nvidia Graphics Drivers on Debian
http://wiki.debian.org/NvidiaGraphicsDrivers#Installapre-builtmodule

Alternatively install Linux Mint as a dual-boot with Windows using mint4win without partitioning mint4win works the same as Wubi as described below (not available on Linux Mint Debian)
http://www.psychocats.net/ubuntu/wubi

You keep Windows as it is, mint4win only adds an extra option to boot into Linux Mint. mint4win does not require you to modify the partitions of your PC, or to use a different bootloader, and does not install special drivers. It works just like any other application.

mint4win keeps most of the files in one folder, and if you do not like it, you can simply uninstall it as any other application.

Boot in to windows insert the Linux Mint LiveCD and you will offered the option of installing inside windows which is where the mint4win installer comes in, you will be asked how many gigabytes you wish to allocate to Linux Mint (I recommend 8gb) then you set a password for your installation then click install and thats it.

Once Linux Mint is fully installed upon starting your PC you will be given a choice of which operating system you want to use Windows or Linux Mint

You download the ISO. image of Linux Mint 9 or Linux Mint Debian then you need to create a Bootable LiveCD/DVD for installation

Linux Mint 9 and Linux Mint Debian can also be run direct from the LiveCD/DVD from Booting up without touching your Hard Drive

How can I remove Linux from my computer and restore the partition space to windows?
Q. I have both Linux Mint 11 and windows 7 on my computer and I no longer want it on my computer so... ya, pretty much says it all in the title.

A. (NOTE: A page titled "How to uninstall Fedora" was added to the project wiki after this blog was published, as noted in the comment section below in a post titled "Contribution is easy.")

Try "remove Fedora."

Nothing.

Go to Ubuntu's official documentation site and search for "uninstall Ubuntu."

You won't find anything in the "official" documentation but in the "community" section you find two entries that state "Wubi allows you to install and uninstall Ubuntu...."

In an installed Ubuntu distribution, clicking on Help and searching for uninstalling or removing Ubuntu finds nothing. A link ârepeat the search online at the Ubuntu help pagesâ brings up a 404 â page not found.

If you look hard enough on the real community support pages you'll find a post from July 2007 titled "HowTo: Remove Ubuntu (& Restore Windows)" .

Have a cow
The post starts out: "Okay, I know some people are going to have a cow because I'm posting this."

(No kidding. Just take a look at the excoriating flames that are sure to appear in the comments section of this blog.)

OpenSUSE does better. A search there finds the page titled SDB:How to Uninstall Linux from December 2006. The page includes more than 1,300 words to describe various processes.

Go to Google and search "install Linux" and you get about 1,450,000 hits. Try "uninstall Linux" and you get about 16,800. "Remove Linux" gets you about 53,300.

Why is it so hard to find instructions to remove Linux and then so hard to actually do it?

Why can't you just easily find the uninstall procedure in a help file, and click a button and follow the instructions?

Windows makes it easy
Opening the Windows XP Help and Support Center and searching for "uninstall Windows" brings up, first thing, "Uninstall Windows XP" and a 5-step process from the Control Center.

Did you know that in a dual-boot install Linux will partition your hard disk and if you remove the partitions without restoring the Master Boot Record on your boot-up disk, your computer won't start?

Did you know you'll likely need separate applications such as fixmbr or fdisk or partitioning software to get your system back the way it was, hopefully having not lost any data? Or you may need to change a BIOS setting to boot to a Windows CD and use its "Recovery Console?" These all depend on your version of Linux. Again, openSUSE seems to do the best job in automating the process, with the "YaST2 Control Center."

Oh, and if that dual installation included Windows, and partitions were resized, "Microsoft does not support Windows installed on partitions manipulated in this manner."

So it's just you and that Linux documentation. Good luck.

Now, I don't have any great love for Windows and I like Linux. I really do. I'm going to use it and learn a lot more about it.

But if you're a newbie like me, you'd best be warned. Searching various Linux forums finds a lot of users who have had problems uninstalling the OS and have lost data in the process.

Go back to Windoze? You're stupid
And while there are some helpful Linux aficionados who try to help these people out -- and others searching for uninstall help -- there are too many posters who take the attitude along the lines of: "Why would you want to uninstall Linux? That's crazy. You must be stupid to want to go back to Windoze."

If you want to try Linux out while keeping Windows, it's a real good idea to try it from a "live" Linux CD/DVD instead of installing it on a hard disk. Iâve tried several. The response is slower, of course, but you get an idea of how it works and donât risk losing anything. For Ubuntu the Wubi installer accomplishes the same thing by treating Ubuntu as a Windows application.

Do your homework
If you do install Linux on a disk, make sure you do a full system backup. And make sure you have a bootable "rescue" or "system" CD. And really do your homework. Read up on disk partitioning and logical volumes and extended partitions and mounts; and GRUB and LILO bootloaders; and NTFS, FAT 32 and ext3 file systems; and gparted and maybe the commercial app Partition Magic -- which supposedly merges/resizes partitions without destroying data -- and so on.

Then read it all again. And be careful our there.

What are the differences between UNIX and Linux, and what about all those choices within Linux?
Q. What are the operational differences between Linux and UNIX? Why would a programmer choose one over the other? What about software selection and ease of programming (with already basic knowledge of programming, and wanting to dive in to open source)?

In terms of Linux, what makes things like Red Hat cost money and things like Ubuntu not? Is pay-for OS based on Linux better quality than freely distributed OS? What is the best choice for Linux-or-Unix OS for a budding programmer?

A. What is Linux
http://www.linux.org/info/

What is UNIX
http://www.unix.org/what_is_unix.html

Why Linux is Better
http://www.whylinuxisbetter.net/

Linux is open source therefore in most cases free of charge with the exception of enterprise releases such as SUSE Linux and Red Hat
http://www.novell.com/linux/
http://www.redhat.com/
http://en.wikipedia.org/wiki/Open_source_software

What is Ubuntu

Ubuntu is a community developed operating system that is perfect for laptops, desktops and servers. Whether you use it at home, at school or at work Ubuntu contains all the applications you'll ever need, from word processing and email applications, to web server software and programming tools.

Ubuntu is and always will be free of charge. You do not pay any licensing fees. You can download, use and share Ubuntu with your friends, family, school or business for absolutely nothing.

We issue a new desktop and server release every six months. That means you'll always have the latest and greatest applications that the open source world has to offer.

Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server. With the Long Term Support (LTS) version you get three years support on the desktop, and five years on the server. There is no extra fee for the LTS version, we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.

Linux Mint 8 can also be run direct from the LiveCD from Booting up without touching your Hard Drive

Option Two (Install Linux inside Windows)

Installing Ubuntu as a dual-boot with Windows without partitioning

What is the best Linux Magazine and/or book for beginners to linux?

Q. I just recently moved from windows xp to LInux and I would like to know how to fix dual boot problems. I learned a few things about the command line but I want to learn a lot more. I also need to know how to download and upgrade software like Adobe flash player and other programs. In other words I need a really good book or magazine that will help me get started. I would of course prefer something simple and fast.

A. Linux Journal

http://www.linuxjournal.com/

is the original Linux Magazine. Well, not the original but the oldest still running and widely regarded as the most authoritative.

Linux Format is the most expensive, about $15 here in New Hampshire. Nevertheless it almost always comes with an install or live CD or DVD and the articles are always of excellent quality. I strongly recommend picking up as many issues as you can afford:

http://www.linuxformat.co.uk/

Anything from O'Reilly Press is also well worth the money.

http://oreilly.com/linux/

Also there are forums, like th Ubuntu Forums (go to Ubuntu.com and look for them on the bar on the left) or the forums at http://www.linuxquestions.org ). There are also the Usenet groups which remain lively years after most have become moribund. comp.os.linux heirarchy is subscribable to via google groups. Oh, and many of the developers contribute to the last. Some of them contribute to Ubuntu forums too but Ubuntu assembles their OS out of packages from many sources so very few people work for them and those that don't you are more likely to run into on Usenet.

What is the best journal software?
Q. I want to start a journal on my laptop and I was wondering what journal software (that is free) is the best.

A. Notepad++ on Windows, TextWrangler on MacOS, Gedit on Linux

what PXE Linux Distribution is right for me?
Q. I'm looking for a Linux distribution with a GUI that can boot live with PXE. It must come with Gparted and must be light weight enough to run in as little as 92 MB ram and a 266 MHZ Processor. I'm not in the least concerned about the speed the Distro has. thanks in advance
Turns out that i have 192 MB ram....so increase the min ram too that.

A. alot of people setup their PXE servers with Red Hat, Ubuntu or Debian.
There was a pretty good how to article about seting up Red Hat PXE across networks in last months linux journal if you can find a back issue. Also, here are some web links as well.

http://www.linuxjournal.com/article/9963

what will happened to the drivers of my pc if i change from win7 to MAC or Linux?

Q. i am planning to change my OS from windows 7 to MAC or Linux but i am quite afraid that if i do it, the drivers in my printer, camera, motherboard, bluetooth, joystick, ect. won't work anymore.
i just wanna confirm, if my doubts are correct that the drivers that i have right now will no longer work if ever i install MAC or Linux.
i also wanna ask your advice with what versions of MAC/Linux should i use? and why?

A. linux and mac also have built-in drivers
but some of your drivers have to reinstall them (with Linux and mac versions)


i will recommend you Linux

Linux Advantages (short)
Open Source
its free
less virus

Linux Advantages (full description)

#1 Low cost: You donât need to spend time and money to obtain licenses since Linux and much of its software come with the GNU General Public License. You can start to work immediately without worrying that your software may stop working anytime because the free trial version expires. Additionally, there are large repositories from which you can freely download high quality software for almost any task you can think of.


#2 Stability: Linux doesnât need to be rebooted periodically to maintain performance levels. It doesnât freeze up or slow down over time due to memory leaks and such. Continuous up-times of hundreds of days (up to a year or more) are not uncommon.


#3 Performance: Linux provides persistent high performance on workstations and on networks. It can handle unusually large numbers of users simultaneously, and can make old computers sufficiently responsive to be useful again.


# 4 Network friendliness: Linux was developed by a group of programmers over the Internet and has therefore strong support for network functionality; client and server systems can be easily set up on any computer running Linux. It can perform tasks such as network backups faster and more reliably than alternative systems.


#5 Flexibility: Linux can be used for high performance server applications, desktop applications, and embedded systems. You can save disk space by only installing the components needed for a particular use. You can restrict the use of specific computers by installing for example only selected office applications instead of the whole suite.


#6 Compatibility: It runs all common Unix software packages and can process all common file formats.

#7 Choice: The large number of Linux distributions gives you a choice. Each distribution is developed and supported by a different organization. You can pick the one you like best; the core functionalities are the same; most software runs on most distributions.

#8 Full use of hard disk: Linux continues work well even when the hard disk is almost full.

#9 Multitasking: Linux is designed to do many things at the same time; e.g., a large printing job in the background wonât slow down your other work.

#10 Security: Linux is one of the most secure operating systems. âWallsâ and flexible file access permission systems prevent access by unwanted visitors or viruses. Linux users have to option to select and safely download software, free of charge, from online repositories containing thousands of high quality packages. No purchase transactions requiring credit card numbers or other sensitive personal information are necessary.

#11 Open Source: If you develop software that requires knowledge or modification of the operating system code, Linuxâs source code is at your fingertips. Most Linux applications are Open Source as well.

How to format or wipe a compact flash that is used for an embedded operating system?
Q. I have an ATP 4GB Compact Flash that is used for a computer and not for photos or with a camera.
It is Linux OS and after I format it in Win XP, the files are still there. Is there a program such as Boot and Nuke(which is for IDE drives) that will wipe the compact flash clean??
I've also tried to fdisk/format in DOS which does not work either. Any suggestions?

A. I'd say you have a bigger problem. Formatting isn't typically conditional. You don't complete a format, only to find that there are still files a card or drive. When a new file table is applied to a media device, it should be destroying any data on the card. I would use the Windows Disk Utility to delete the partition on that card, and then apply a new format to the drive. Do not use the Quick Format option either.

Do you think a Unix or Linux Administrator can get a job almost anywhere in the world easily?
Q. Let's say a person from America go to Asia, Europe, Africa, South America, or whatever. Do you think it would be easy to get a job since they have Linux Administration experience?

A. if you have the Linux qualifications then yes you will get a job any where in the world,
Linux runs the Internet,
Linux runs 455 of the worlds fastest top 500 HPC (High Powered Computers) Microsoft have 1 HPC in the bottom 45 (their own system)

You use Linux every day and don't know it, Linux run all domestic appliances from TV's Microwaves, Washers, Dryers, In car computers The list of embedded Linux in use is endless
