sudo How to switch Linux account user without the target users password
sudo How to switch Linux account user without the target users password
Did you know if you have been granted sudo access to a remote host with su command, then you may switch to any user without the need to type in their password?
Try this out:
zemian@myhost bash> sudo su - postgres
# When prompted for password, enter your own user account password.
# Now you are in as `postgres` user!
postgres@myhost bash>
Or if you want to switch to the root user directly, simply try:
bash> sudo su -
This is very useful when you need to switch to a user account that was only setup just to run applications (eg: postgres, mysql, oracle, or weblogic etc.) and not intented for real user. In this case, you might not even know what the real password is. Above trick should get you switch into that target user account.

Swap space Partition in linux
Swap space Partition in linux
Pranaam to all bhai ji _/_
In this post we will discuss about swap space partition and its creation via command line .
swap space partition is that partition which is needed when we are running on low RAM in our system.
swap is used as RAM in system when we dont have enough space and we need to store data on RAM
requested by a process .
in short, swap is inactive RAM which role comes in play when our RAM is full :) . if we have enough RAM in our system , we dont require swap space.swap space memory size doesnt need to be set as DOUBLE OF SIZE OF RAM (as many people says).if we have enough RAM, we even dont need swap partiton.
so its depends on you, how much space you want to allocate as swap for your system.
alike storage partition, we dont mount swap partition but swap partition need to activate(on) so that system can use it :) .
ok lets starts, first of all we will learn , how to create swap space in linux environment(OS) .
There is little bit difference between creation normal partition type and swap partition. we just need to change partition type of new created partition via command line using fdisk utility(we have discussed about how to create partition using fdisk in post http://mannulinux.blogspot.com/2013/07/partition-or-file-system-creation-in.html )
so lets start
we need to enter into hard disk using fdisk command .to find out harddisk name run command fdisk -l
and you will get output like this
my main hard disk name is /dev/sda
command will be fdisk -c /dev/sda
and i will be in hard disk with command line interface. now type n and press enter to enter into new partition creation mode.
select any partition type (either primary or logical as we will change it later so it doesnt matter).
i am selecting bydefault i.e primary partiton by typing p
select partition number or press enter for by default number(its 3 in my cse and new partition will be /dev/sda3 3 will be added with disk name /dev/sda+partition_number=/dev/sda3)
allocate the space , i am creating partition with 60 MB size by specifying +60M (you can specify total size of partition either by sector number, which is not comfortable or use +sizeM/G M stands for MB and G stands for GB). have look on screenshot for batter understanding :) .
now we have to change partition into swap type .
type t in command line interface and press enter and prompt will ask for partition number whose type has to change. we have just created partition 3 , type 3 and press enter. now screen will come up and will ask for hex code of partition compatibility . for swap partition hex code is 82 and for other partition type hex code type l in command prompt and press enter .
here is the list of hex codes
ok , type 82 and press enter, we will get message that partition has changed into 82(linux swap)
it means , swap has been created.
to write changes on disk , type w and press enter to save changes to disk .
reboot system or run command partprobe to update partition table list in kernel
okkkkkk, we have updated kernel partition table too.
we need 2 more step to complete with swap.
now specify /dev/sda3 as swap by running this command " mkswap partition_device_name "
example :- mkswap /dev/sda3
now run command to activate swap on system
command is :- swapon partition_device_name
in my case partition_device_name is /dev/sda3
so command is swapon /dev/sda3
hell yesh , we have done m/
now run swapon -s command to check your activated swap partitions on you system with its available and used space :)
this was the procedure to create swap and activate it
Thank you

switching to Linux read this!
switching to Linux read this!
one of the reason windows is considered as a synonym of the computer among non-geeks is its simplicity, everything can be learnt in a jiffy .for most of them nothing even exist except windows but one big problem that frustrate people is its virus catching ability,which causes a great deal of headache to its users in form of system format and squandering money in buying antiviruses(since licencing of windows and close source are not even a point about which indians and non-geeks ever bothered), and this is how people start looking for other options rather than windows and sometimes boys in engineering try out linux just out of curiousness(I am not sure about girls :-D ).so here are the points which must be taken in to consideration before switching to linux or you will endup abusing linux and taking step back to windows.
1. first if you are a gamer type of person then never ever fully switch to linux because gaming in linux sucks(for real believe me :-( ).windows is heaven for u guys.
2. try UBUNTU or LINUX MINT first rather then any other flavor of linux because UBUNTU and MINT are simplest and most advance linux available right now.(ubuntu can even be installed in windows as an application and then try it. it is simplest method to try linux or using the live option while booting from linux dvd)
3. check out your wireless card (network interface card if it supports linux or not) because without it linux would become a bigtime mistake..
To know about wireless card, run this command on linux terminal(boot using live cd or wubi)
just press "ALT+F2" and type in "gnome-terminal" or "konsole" and press ENTER "lspci | grep -i wireless".
if you are lucky as me to have broadcom wireless then here is the guide if not then google regarding your nic card.there are hosts of websites which will surely let you know whether your card supports linux or not. if it doesnt supports dont panic buy netgear wg111 v3 which is cheaply available and supports linux.
4. if you use android phone then you are lucky buddy,no problem no drivers needed to connect android to linux and using tethering internet connection can be established in easy way but if you use some kind of usb modem(e.g. micromax ) then be careful because drivers are not so eaisly available for all of them.(for this point you have to be little bit technical to apply) check out the links below...you will get the help.micromax 3g usb, micromax 353 g wireless modem, BSNL Micromax mmx 300G USB MODEM .
5. if you do some work with printer then before switching to linux watch out if your printer is supported by linux.visit these 2 pages carefully-: check support for your printer, how to setup a printer in ubuntu.
if all the above described things are in your favour then you are ready to switch to linux and beware linux community never believes in spoonfeeding so one must always be willing to learn.all your desktop needs will be satisfied by the desktop version of linux and plus you get a solid ,stable, non virus catching, free of cost, operating system.but do consider donating some money to these organizations as they are working for mankind and ofcourse it helps save your lots of money in form of no licencing ,no antivirus,free softwares,no untimely formatting,protection of data so why not donate a little part of it to linux communities.do let me know what you think about this article in comments...

SwiftBoot kick starts Linux in under one second
SwiftBoot kick starts Linux in under one second
Are you happy that your Linux OS boots up real quick, say in about 40-60 seconds ? Do you really think thats the best Linux can do ? Certainly not, Linux is getting better and better everyday, it has come a long way and has proved to be considerably good at what it does. A company called MPC Data has developed a solution called swiftBoot that helps booting into a fully running Linux OS in under one second.
Heres a video demonstrating its booting speed:
No other gimmick involved other than optimizations done, as a result of a good understanding of the Linux system.
Heres another one on a TI OMAP3530 based OMAP3530EVM board. This time, they use a stop-watch for monitoring the performance.
The demos show that not only does the system soft-boot in within a second but it also function normally after that.
--Expecting to see more of such advancements in Linux systems.

Story of my Gateway VX1120 and Custom Refresh Rates on Windows and Linux
Story of my Gateway VX1120 and Custom Refresh Rates on Windows and Linux
A few months ago I picked up a Gateway VX1120 from a computer store in town for $5, not knowing if it would work or not. I was always a fan of CRT monitors, and seeing something of this size, I had to jump on it.
Got it home, plugged it in, and found out that it worked fine. Instantly replaced the Acer S201HL I was using without regrets. Colors were more vibrant, and animations are much smoother (one of my favorite things to do when switching from LCD to CRT is to move a window across my desktop to observe the smoothness). Plus the resolutions available were extensive, so I was sure I could find the right resolution to use daily. The other CRT monitors I have in the house were limited to around 1024x768, or something slightly higher at a lower refresh rate, so they werent too ideal.
After some time, I found that the resolution of 1280x960 suited perfectly as a default resolution. Its not high enough to make text hard to see, and at the same time, its large enough for the desktop not to feel cramped. The highest stock refresh rate for this resolution was 85Hz, which was great and all, but I soon looked into a way to improve that.
On Windows, I used a tool called Custom Resolution Utility (CRU). It allowed me to generate custom resolutions and refresh rates. I wanted to run at 120Hz just to be able to claim I had such a monitor, so that was the first refresh rate I tried. It didnt work; and the monitor complained about the frequency being out-of-range.
After a little bit of research, I found that my horizontal scan frequency could go as high as 121kHz. So going by that, I then had the idea to keep trying resolutions with CRU until my horizontal scan frequency was just under that limit. Lucky me, 119Hz seemed to have worked fine.
So in Windows, the refresh rate wasnt too hard to handle. Things got a bit more interesting when I went over to Linux however. I use an AMD Radeon HD 7850 graphics card (this specifically), so I have the choice of either using AMDs proprietary driver (fglrx), or the open-source drivers. The refresh rate on my screen however seems to act differently depending on which driver I use though.
If I recall correctly, I was able to use the CVT-generated 119Hz with fglrx without issue (its been a while since I used fglrx with this monitor), but this wasnt the case with the open-source driver.
Looking back at cvt, I noticed that my hsync value was 122.59 for 119Hz. Definitely over the 121kHZ limit, so then I tried going to 118Hz. It ended up at 121.45, which was still over the limit. I wasnt sure if 121kHZ was a hard limit, so I added the refresh rate and tried it anyway. Both 119Hz and 118Hz failed to work; so I tried 117Hz. Got the hsync value of 120.31, which was safely under the limit, and worked fine.
Im unsure how CRU and cvt generate the numbers they do, but a comparison at some point would be a great idea, whenever I find the time to do so.
So far, this monitor is still working great, and I have no plans of replacing it anytime soon, unless I go back to my standing desk setup.
