Q. I have root access on a remote linux box and want create a user account for friends to FTP files. For example I want to create a new user called friendftp and give them permission to copy files from and to a directory called /mysite.com/ftpdrop.
Any help?
Any help?
A. open your terminal and type:
sudo useradd -m -g users -G **groupnames** -p **password** friendftp
sudo useradd -m -g users -G **groupnames** -p **password** friendftp
how can i create a root previledge user?
Q. I need to create another user in linux which will have all the previledges of a root user. Please suggest me how to create a user which will have all the power of root.
A. If the above didn't help, instead of giving someone the root password, you can try configuring sudo if it's Fedora or Ubuntu linux, the file /etc/sudoers contains a lot of options to fine-tune it
How did microsoft become such a monopoly to PC manufacturers?
Q. I am a linux user and it does not seem right that one company can be in a oligopy with no other competitors. Other than a netbook from two years ago, i have never seen a computer for sale at a store without the windows os(not even a mac).
A. A long time ago, in a land far away....
Computers back then weren't these small home machines we have now because there wasn't an operating system that a typical home user could make any use of. Computers were massive machines with complicated systems that usually required a programmer because we also didn't have things like MS Office or Quickbooks yet.
Mr Gates and some other people thought it would be cool if everyone could have a computer in their house. The hold-up was an operating system that would allow small machines (and back then we thought an 8 bit machine with a magnetic tape drive was some hot stuff) to function usefully for every-day users. So he (and some others) created/modified an operating system (DOS) that could do exactly that. IBM made a small machine (PC-Jr then PX-XT) that could use that system and was inexpensive enough for most people to own. It didn't require a master's degree in computer science to operate but did require a bit of a nerd.
Some other computer makers started making home computers around that operating system and specification (PC compatible) that had good uses for everyone at home and at work. And it grew exponentially very fast. And then, Microsoft tossed out Windows (esp. 3.1 then '95) and the way we compute changed immeasurably. Any 4th grader could use a computer then.
So imagine that you invented a certain kind of fuel and then all of the car makers started making lots of cars that run on your fuel. They could have made cars to run on other fuel - and some did - but almost everyone had a car that runs on yours. What happens to your company? It just grows and grows and after a while just about everyone expects that "cars run on X fuel with few exceptions"
That's what happened at Microsoft - computers used MSDOS and Windows, with few exceptions.
Now, they don't really have a monopoly because, as you noted, Linux (and others) remain an option. Nobody made a law that says "you must use Microsoft products" and you're free to use whatever OS you'd like or even write your own.
So how did Microsoft get in the position they're in now? 1) they were very early to the market 2) they continued to improve their line 3) they produced a product that other companies based theirs upon so that the MS product became essential 4) They didn't give it away for free so they could afford to keep improving it.
Whether it's "right" - what if you had created DOS and Windows? Would you give it away for free so that Dell, Gateway, IBM, Asus, etc... could all make lots of money off of your work? Would you share all of the source code with everyone in the world so they could make it too - and sell it to other people without giving you any money? No, I didn't think so. Me neither.
But, if you don't like Microsoft products you have plenty of company and are free to use whatever other OS you'd like (or to write your own) and nobody will complain. It's one of the great things about a free market - even a free market that has huge big players in it. You can write your very own operating system and sell it to whoever likes it. If yours is as good as theirs, you might even take their place. (Firefox and Google took someone else's place in the market that way)
