I was working on this project for about 2 months now,

our aim was to develop a live community for the Linux user’s specially of Bhopal(M.P.) India

This happened to be the main reason for my absence from the blogging arena.

So in order to form a live discussion community based, we came up with an idea of a discussion forum, and after a few days workout, we found mybb most suitable.

took us almost 30days to reach the post marks currently present as well as get the video gallery setup.

http://forum.linuxgurus.info

http://forum.linuxgurus.info/vgallery.php : - video gallery.

but the good news is

SITE LAUNCHED YESTERDAY.

after 48hrs we have got

14 new registrations

above 150 visitor

Note: hope this trend continues and the forum gets going steadfastly.

To look at the options to provide a virtual machine to run windows on Linux.

i had multiple options

Complete virtualization (virtual machine)

1) Bochs (I have used it a few years back and found it good, but it only lacked a graphical configuration manager)

2) VMWARE (one of the best in terms of ease of use but i have to reject it in due to its licensing)

3) XEN (text on net says a lot about it but till now i am unable to establish a xen server what i want to do is to set a windows guest but i have not found an option for it till now.)

then a site came into view the screen shots seems quite impressive and so came the fourth option in my mind

4) innotek virtualbox (although its proprietary in its fullest, but a limited version is also released in GPL, and both versions are free for educational and not for commercial use.)

See more about the latest version of virtualbox here

Emulation

5) Wine - a nice piece of software, till now i have been able to succesfully run

i) macromedia dreamweaver 8.0

ii) adobe photoshop cs2 tryout

iii) winzip, winrar and other compression tools

iv) AVR studio 4

v) WinAVR

vi) Boson Netsimulator

vii) need for speed II SE

viii) AVRlibs

6) DOSBOX

Well i have been dieing to try my hands on those nice games available to me during the good old days of dos, which includes jazz jackrabbit and others which i was unable to on XP, even under compatibility mode.

This nifty utility is now installed on both my windows and Linux box and is helping me run those old applications which worked on dos only (or at most win98) environment.

You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn’t have installed that bad driver, but you did it anyway. So you reach for the power button. Stop. Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job. 1. Hold down the Alt and SysRq (Print Screen) keys. 2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB 3. Watch your computer reboot magically. What the individual keys do in that sequence are not as important as what it does as a whole: stops all programs, unmounts all drives, and reboots. A lot safer than just cutting the power. Here it is again: REISUB. Remember that, as it will save you a lot of time when you are configuring a system and something gets messed up. Need a mnemonic? Try Raising Elephants Is So Utterly Boring. As an aside, don’t try this if you just want to reboot. A normal reboot, if it can be done, should always be used instead of the REISUB keys. R-E-I-S-U-B. Source & Author: Jacob from FOSSwire

This is one of the problem faced by many person’s

“what if i lost the root password”

FOR DEBIAN

First thing that comes in mind is “use single user mode” but the answer is NO.
coz debian takes the system security to one more level up and by default ask’s for the root password.

so the BIG QUESTION IS HOW TO proceed further

follow these steps

1) on grub-boot prompt.
press “e” to enter edit mode

2) then press downarrow to reach the line that starts with “kernel ”
press “e” again

3) at the end of this line type in “init=/bin/sh” or “/bin/bash”

4) then press enter to make that change and press “b” to boot

in a few seconds you will be on your “#” prompt

5) only one step left
“mount -o remount rw /”

this step is necessary coz in this case root file system is mounted as read only.

6) finally type “passwd” and you get the screen to change the password

and then type in “init 6″ or “reboot”

NOTE FOR TECHNICAL USERS
those who are looking for the technical details, the main work is the init command that we passed as an argument to kernel, it told kernel to specifically run the command specified in parameter instead of working on normal routine.

TRICK = if you have any program you wish to run instead of this then you can do that too using init command only.

FOR REDHAT

use single user mode and change the password.

but that’s a potential pitfall. coz any person can start system in single user mode and get the password changed.
