how can i install a linux into a network computers at the same time with and w/o using ftp or http servers?

Q. i want to install fedora core into multiple computer through a network environment without using any servers. and i wanna do the same for ubunto but this time using ftp server and another time http server.
if anyone knows about any plz tell me.

A. Since the answer to that is rather involved and can be complex as with different OS systems.. I will just point you to a site that tells you how.
http://systembash.com/content/unattended-remote-os-installs-linux-windows/

However, a machine on the network will be a server! (it can be just any old machine but since it will be auto delivering the OS it will be working as a server!) You can use a tftp server program on a designated machine but that is a server! Again, any computer can be used but it will be used as a server to accomplish the installation.

That will work for Linux (any version) or Windows.

How do I figure out what type of Linux I'm using?
Q. I have a virtual server but it doesn't have Java. I'm going to install it, but I need to figure out what type of Linux is on the virtual server. How do I figure this out?

A. The command

$ uname -a

will give a lot of info about the running kernel. Also

$ dmesg|less

shows you a lot of detailed information about the system. The first line here shows you the exact kernel build, flavor and which version of gcc was used to compile it. If you still don't know exactly which release of Linux you have, look into the directory /etc for a file named redhat-release (for Red Hat/Fedora/Cent OS), SuSE-release, debian-version or ubuntu-version (for Ubuntu/Debian). You can do this very easily using just one command:

$ cat /etc/*-{version,release}

If your server isn't something very exotic, this will show you the flavor, release and version information of your Linux system.
Kind regards.

How can I bypass K9 Web Protection without a password?
Q. My mom installed a filtering thing called K9 Web Protection. Unfortunately, that puts me in the dark, and I have many accounts that need monitoring. Can someone please help me find a way to unencrypt the password for me so I won't have to delete it? By the way, don't answer "Ask your mom, blah blah blah, she will take it off" because I have tried that too many times, and it don't work. Trust me. Anyone have any suggestions?

A. Lol... the Wikipedia entry for this software tells you how to bypass it :) Well, they share the weaknesses anyway....

The first thing I might try is a VPN. VPNbook.com is free, and if it uses a secure port to connect to the VPN server, it'll bypass the software's blockages. You may be able to bypass it with certain proxy servers or SOCKS proxies, too. Just, it's a bit iffy when logging into sites when you're connected to a VPN or using a proxy: if they site you're logging into isn't encrypted (https), the proxy or VPN server owner can see and maybe could record your login data. It's a risk, but people use them all the time.

The second thing I might try is to install a new operating system on the computer by way of a virtual machine. You'd need something like VM Ware or Virtual Box (both on Filehippo.com) and an Operating System disk or disk image.

The third option, which might be easier to do than #2, but possibly more difficult to fully implement is to setup a Linux operating system on a thumb drive, and boot your computer up with that. Just today I installed Tails on a USB thumb drive: https://tails.boum.org/index.en.html and it literally took me less than 15 minutes to be up and running, and most of that was due to writing files to my slow USB flash drive.

To make a Linux Live CD on a thumb drive:

1) Choose a Linux distribution. Maybe Google 'best linux distro for live CD', but popular distributions are Knoppix and Ubuntu for a live CD-type installation. Download an ISO image - they're available from the respective sites or all over, and legal to download.
2) Download Rufus: http://rufus.akeo.ie - you take the disk image / ISO for the Linux distor, then use Rufus to install the ISO on the thumb drive making it a bootable ISO.
3) Change the boot order in your BIOS settings. Get into your BIOS settings, and change the order to put a USB drive above the hard drive. Save & exit, and if you have the Linux Boot Drive plugged in & installed correctly, you'll boot up to that instead of windows, and completely bypass this software.

A couple things on #3 -

* You'll need a USB flash drive. Faster would be better, but even slower is ok... probably 2GB-4GB would be enough, but this depends on the requirements for the Linux distro you choose.
* The USB flash drive will lose all data currently on it. So, don't try setting this up on something that has important files on it.

I've used Ubuntu, Debian (by way of Tails today), Fedora and Knoppix - most are pretty easy to start using in a basic sense. If you're pretty comfortable on your computer, you'll be able to figure out basic things on most Linux distros and at least get connected to the internet, browse, etc. And, if you're only needing to monitor various accounts then maybe the live CD option would be best as it won't leave any traces behind, either.

I realize this isn't comprehensive, but hopefully it'll give you enough to get started on a fix.
