11 ways to Completely Remove unwanted files from Ubuntu/Linux

Today i am going to write a new post about "Safely Removing unwanted files from your Linux/Ubuntu partition to free-up more space for new application's and speedup performance of OS" . I have collected some best and safe way to erase unwanted files from linux, and i listed those way for you.

Important's of removing unwanted files:

• our first gain on removing unwanted files is freeup hardDisk space.
• large amount of unwanted files will make linux slower under some condition's.
• getting more space to installing new application's.
• erasing some evidence of your activity
  
• and make your system control in you hand.

Here is the 11 ways:

first of all we should know which folders are used as TMP and cache in linux to delete them.

Thumbnail's:
your photo gallery thumbnails are created in the following folders

home/user/.thumbnails/normal
home/user/.thumbnails/large
home/user/.thumbanils/failedtoload

you can delete these folders. this thumbnails folders takes 28Mib on my PC.

Installed app's Package's:
when ever you use apt or synaptic to install packages. it will download packages and save those packages to this directory.

var/cache/apt/archives

you can delete these packages,but before deleting this files you should remember "these files are your need application's .deb so if you want to install this packages in future without download new files, please move these files to other places.


$ apt:
apt-get have feature to remove no longer needed packages from ubuntu. todo run this commend on terminal:

$ sudo apt-get autoclean

Synaptic Package manager:
in synaptic package manager click on status button on left bottom, and then click on "Not installed (Residual config)".now synaptic will give list of packages that you removed, if anything there mark all for complete removal, and then click apply.


Remove Package configuration files:
When removing a application apt also give you a list of no longer needed dependencies to remove. When you select purge(ie: completely remove) will erase only packages, the configuration files will remain to remove these configuration files you need to run a simple bash code.

Run in Terminal:

#!/bin/bash
echo "Searching for unwanted configuration files..."
purgelist=`sudo dpkg -l | grep ^rc | awk 'print $2 '`
sudo aptitude purge $purgelist
exit 0;

Delete files older than X days:
here we using find utility for this. this code will search for a file that older than X(user decided) days on the directory and delete.

find /path/to/files* -mtime +5 -exec rm {} \;

Auto remove on shutdown:
ubuntu stores many TMp files on /tmp folder. we have an idea to automatically remove these when each time you shutdown.

Sysklogd provides two logging services, one for your system and the other for your kernel. It sits in /etc/init.d/ and is a service that starts and stops with your computer. we need to modify this file to remove tmp folder.

first create backup of this file:

sudo cp /etc/init.d/sysklogd /etc/init.d/sksklogd.bak

Now we can modify our file with a happy conscious knowing we’ve made a backup.Now we can modify our file with a happy conscious knowing we’ve made a backup.

gksu gedit /etc/init.d/sysklogd

here i am used gedit to edit this file.
Once you’ve got it open, look for the part that says:

stop)
log_begin_msg “Stopping system log daemon…”
start-stop-daemon –stop –quiet –pidfile $pidfile –name syslogd
log_end_msg $?
;;

You’ll want to add the below line just before the double semi-colons “;;” above. Note also that “;;” looks something like a spider face, which may be of use to you at some point down the road.

rm -fr /tmp/* /tmp/.??*

That’s the command that will remove just about anything from your /tmp directory.
Once you’ve added it, save the file and exit Gedit. When you shutdown, your /tmp directory will have emptied!


Removing dupe file's:
there is a nice program to find duplicate files from linux named as fdupes.
to install fdupes(15KiB or near):

sudo apt-get install fdupes

fdupes calculates the md5 hash of the files to compare them, and since each file will have a unique hash, the program identifies duplicates correctly. I let it run in the directory which contains my files recursively (which makes it check for duplicates across different directories within the specified directory, and saved the output to a file by doing:
$fdupes -r ./stuff > dupes.txt

Then, deleting the duplicates was as easy as checking dupes.txt and deleting the offending directories. fdupes also can prompt you to delete the duplicates as you go along, but I had way too many files, and wanted to do the deleting at my own pace. The deletion function is useful if you are only checking for duplicates in a given directory with a few files in it.

and also don't forget to clean your trash!

Softwares with GUI:
you can use the following applications to remove unwanted files on linux. these app's can delete some files listed above,the sad newes is still there are no app to remove all unwanted files on linux, we have to do all in manual.
ok here is the list of 3best apps:

KleanSweep
BleachBit
CleanUpCruft

HowTo: BackUp and Restoring Deb/Packages on Ubuntu [Offline restoring]

This is howto guide for *buntu box users to BackUp all installed deb packages and Restoring/installing them quickly and efficiently no need to download again again when reinstalling the OS.

Features and Uses:

• No need to download your favourite applications and other required basic things when reinstalling *buntu box
• This become very useful when you want to install and set same setting for multiple computer's on you school,Company or other places.
• No need to get very large amount size of update's every time you reinstalling ubuntu. (If you already updated).

There is no real reason to do this if you are already doing a full system backup (e.g. an image of your Ubuntu partition using partimage). This is just something I discovered and feel could be beneficial to other users.

This comments will do that for you:

todo this backup you need to install a small utility named dpkg-repack fakeroot on your *buntu box.
to install fakeroot run this command on terminal

sudo apt-get install dpkg-repack fakeroot

 after that select place for backup, This may be a extranal drive,ThumpDrive or CD/DVD any thing you want. navigate to selected place using cd commend on terminal. Like this
let assume you are saving all backup deb files to "Backup"(this is foldename you haveto save your debfiles) folder on another partition of the same harddisk named "MyDisk"

cd /media/MyDisk; mkdir Backup

Filnally we are ready to backup

$ fakeroot -u dpkg-repack `dpkg --get-selections | grep install | cut -f1`

This code will take some time to finish. (copy the code except $)

Now if you scroll to "MyDisk", you should find a folder called "Backup" which should have all the deb files of all your installed packages.

Re-Installing of Backup:

Reinstalling is so easy, first navigate to your backup folder using cd command on terminal, and then type sudo dpkg -i *.deb in terminal


Examble:

cd /media/MyDisk/Backup
sudo dpkg -i *.deb

the first code will navigate to backup folder, second code will install all deb packages automatically.

Thats it. Now you have a all packages on you hand.

If you have to say somthing, tell me via comment.

HowTo: NFS Server/Client [Linux]

Why NFS?
I simply wanted to experiment with NFS, and couldn't seem to find the documentation here on the forums. I found using NFS just as easy if not easier than using Samba for sharing between a few of my Unix based systems. In order to share a folder it only required a single line in a configuration file under /etc/exports, and a single line under /etc/fstab on the client to mount the share on each client at boot.

I mostly edited and moved things around from these guides to make a more complete single guide to getting this working using Ubuntu.

http://www.cyberciti.biz/tips/ubuntu...nfs-share.html (for client configuration)
http://www.redhat.com/docs/manuals/l...nfs-mount.html (for mounting using fstab)
http://www.freebsd.org/doc/en_US.ISO...twork-nfs.html (contains more info about NFS)


Install NFS Server Support
at the terminal type
sudo apt-get install nfs-kernel-server nfs-common portmap
When configuring portmap do =not= bind loopback. If you do you can either edit /etc/default/portmap by hand or run:
sudo dpkg-reconfigure portmap
sudo /etc/init.d/portmap restart

Editing /etc/exports
the /etc/exports file is used for creating a share on the NFS server

invoke your favorite text editor or
sudo vi /etc/exports

Here are some quick examples of what you could add to your /etc/exports

For Full Read Write Permissions allowing any computer from 192.168.1.1 through 192.168.1.255

/files 192.168.1.0/24(rw,no_root_squash,async)

Or for Read Only from a single machine

/files 192.168.1.2 (ro,async)

save this file and then in a terminal type
sudo /etc/init.d/nfs-kernel-server restart

Also aftter making changes to /etc/exports in a terminal you must type
sudo exportfs -a

Install NFS client support
sudo apt-get install portmap nfs-common

Mounting manually
Example to mount server.mydomain.com:/files to /files. In this example server.mydomain.com is the name of the server containing the nfs share, and files is the name of the share on the nfs server

The mount point /files must first exist on the client machine.

cd /
sudo mkdir files

 to mount the share from a terminal type

sudo mount server.mydomain.com:/files /files

 Note you may need to restart above services:

sudo /etc/init.d/portmap restart
sudo /etc/init.d/nfs-common restart

Mounting at boot using /etc/fstab
Invoke the text editor using your favorite editor, or

gksudo gedit /etc/fstab

In this example my /etc/fstab was like this: 

server.mydomain.com:/files /files nfs rsize=8192,wsize=8192,timeo=14,intr

 You could copy and paste my line, and change “servername.mydomain.com:/files”, and “/files” to match your server name:share name, and the name of the mount point you created.

Test before Reboot:
type

mount /files

 in a terminal, and the mount point /files will be mounted from the server.     (source: ubuntu forums)

Pidgin – cannot connect to Yahoo messenger [Solution]

I just noticed the abnormality with Pidgin 2.5.5 (running on Ubuntu) these few days, I couldn’t connect my Yahoo messenger account at all. According to the discussion of Bug #389278 it appears that Yahoo was trying to change its protocol.
A quick way to have Pidgin connecting to Yahoo messenger server again is to change the Pager server setting for the Yahoo account in Pidgin.

To do this, from Pidgin:

Manage Accounts (Ctrl + A)
Select the Yahoo account from the list, and click Modify
Click on Advanced tab, under the Yahoo Options, in the Pager server field replace scs.msg.yahoo.com with cn.scs.msg.yahoo.com

save and restart Pidgin, Then  try to connect yahoo messenger. It works for me.
GoodLuck.

Grub cannot detect windows vista after installtion (Solution)

While installing Ubuntu,  the Grub will detect any other operating system itself, but some time grub will fail to do such thing,
Manually Edit Grub Loader: -first try this

---

Manually editing Grub loader is easy thing  you need to edit grub/menu.lst and grub.conf in order to modify the list, i was posted here with Topic of 'How to Recover Grub...'  it'll work with windows vista as well.
If  grub/menu.lst and grub.conf dont exist in your  /boot/grub folder.  you should Reinstall Grub loader .
But the reinstalling of Grub is mostly not possible while running  same OS. - Getting worry?
don't worry about this we can reinstall GRUB by live Ubuntu  ;)

To Re-install GRUB Loader:

---

To reinstall GRUB loader you should need a live CD of ubuntu.

• Boot your computer up with Ubuntu CD
• Open a terminal window or switch to a tty
• Type sudo grub. Should get text of which last line is grub>
• Type "find /boot/grub/stage1". You'll get a response like "(hd0,1)".Use whatever your computer spits out for the following lines.
•  Type "root (hd0,1)", or whatever your hard disk + boot partition
  numbers are for Ubuntu.
• Type "setup (hd0)", to install GRUB to MBR, or "setup (hd0,1)" or
  whatever your hard disk + partition # is, to install GRUB to a
  partition.
• Quit grub by typing "quit".
• Reboot and remove the bootable CD. Thats it!

You have finished the REinstalling of GRub loader.  At this time you can see the you missed OS in boot menu.
If they not listed on boot menu, You may need to go step one for Manually editing the menu.lst file (after reinstalling  grub on same partition of linux will put menu.lst file on grub folder so don't get lose to try first step  )

GoodLuck :)

How to Disable or Remove IPv6 on Ubuntu Jaunty 9.04

IPv6 is designed to solve the problems of IPv4. It does so by creating a new version of the protocol which serves the function of IPv4.but the problem is at now all servers or your ISP's are does not supporting the ipv6. so your internet become very slow.  

Edit: note that IPv6 does not slow down IPv4. Ipv6 is a different from IPv4 in 5 major areas as follows:

1.  addressing and routing, 
2. security, 
3. network address translation, 
4. administrative workload, and support for mobile devices. 
5. IPv6 also includes an important feature: a set of possible migration and transition plans from IPv4.

But the reason for slow browsing is 'DNS resolving time ' because your browser first try with resolve address with IPv6 protocol if its fails and then try with Ipv4 this changing of protocol takes some time this will slowdown your browsing speed.(But the downloading speed of the files are same with these two protocol.) 
Reason for  editing:  see comments.


IPV6 is enabled by default in Ubuntu Jaunty 9.04, even if you upgraded from an old version of Ubuntu. So we need to disable for get your speed back ok let see how to do?

First of all you need to check is IPV6 is enabled or disabled? - for your convince
Run the folloing code in terminal:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

By running this code,Terminal will return  a value  1 or 0
If the value is 1  ---IPv6 is disabled
If the value is 0  ---IPv6 is Enabled      if you get this value you need to disable the IPv6 by next code.

Write this in terminal:

sudo su -
echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

 By running this code you can disable IPv6. If you do no have that directory, you can edit your grub menu:

gksu gedit /boot/grub/menu.lst

this file have bunch of boot comments. Now navigate ubuntu 9.04 generic 2.09 or somthing like this.   
Now add

ipv6.disable=1

to the end of the line.

Note: this trick works with kernels other than 2.6.28.

After do it you may check agian by running first code described above on this page.
GoodLuck. :)

        > exit

  note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.

• Now reboot your computer

Trouble Shooting:

---

If Windows is now missing from the boot menu:   
If you installed Ubuntu before you installed Windows, then Ubuntu will not have anything in the grub configuration for Windows. This is where you’ll have to do a bit of manual editing to the grub boot menu file.

Open the file /boot/grub/menu.lst with the following command:

sudo nano /boot/grub/menu.lst

Here nano is text editor which i use. you can change this to default text editor for linux gedit if you dont have nano

This is a sample codes for  windows in grub loader:

Paste this code into menu.lst file and click save.

title Windows 95/98/NT/2000/XP/XP Pro/Vista
root (hd0,0)
makeactive
chainloader +1

Note that you should also verify that hd0,0 is the correct location for Windows. If you had installed Windows on the 3rd partition on the drive, then you should change it to (hd0,2)

Creating a PXE boot for Jaunty Live

PXE usually involves booting a computer from firmware -- data contained on a read-only-memory (ROM) or programmable read-only-memory (PROM) chip -- rather than from data contained on magnetic media. This gives rise to the terms 'PXE boot ROM' or 'PXE boot PROM' (sometimes written 'PXE bootprom'). Booting from ROM or PROM eliminates the reliance on an electromechanical device (the physical drive). This enhances reliability and eliminates drive read errors. With today's memory technology, booting from ROM or PROM is fast. PXE can be also used to boot a computer from a network.

Preboot Execution Environment (PXE) refers to various methods of getting an IBM-compatible computer, typically running Windows, to boot up without the need for a hard drive or boot diskette. The methods evolved from the era before computers had internal disk drives.

To create PXE boot for Jaunty Live you need the following:

---

• Ubuntu server for PXE environment (tested on Jaunty 9.04 server)
• Wired network
• PXE boot capable network card on target machine
• Download syslinux-xxx.zip
  

Do on Ubuntu Server:

---

• First of all you need to login as Root    (sudo su-)
• Create the directory structure as following:
  
  

  /pxe
  /pxe/images
  /pxe/images/ubuntu
  /pxe/pxelinux.cfg

• Extract the files from syslinux-xxx.zip
• Find menu.c32 & pxelinux.0 & copy them to the /pxe directory (other files on the Zip is no longer nedded can be delete)
• create a file /pxe/pxelinux.cfg/default & paste in the following:
  
  

  DEFAULT menu.c32
  PROMPT 0
  NOESCAPE 0
  ALLOWOPTIONS 0
  TIMEOUT 600
  
  MENU TITLE PXE Boot Menu
  
  LABEL Ubuntu Jaunty Live Desktop
  kernel images/ubuntu/casper/vmlinuz
  append boot=casper netboot=nfs nfsroot=192.168.1.101:/pxe/images/ubuntu initrd=images/ubuntu/casper/initrd.gz -- splash
  
  LABEL Ubuntu Jaunty Live Install
  kernel images/ubuntu/casper/vmlinuz
  append boot=casper netboot=nfs nfsroot=192.168.1.101:/pxe/images/ubuntu initrd=images/ubuntu/casper/initrd.gz -- splash only-ubiquity

• Now copy the contents of the Ubuntu live CD into /pxe/images/ubuntu
• And then install dnsmasq & nfs-kernel-server by run the code on terminal  apt-get install dnsmasq nfs-kernel-server
  
• edit /etc/dnsmasq.conf & replace all text with:
  
  

  no-hosts
  server=/localnet/192.168.52.1
  dhcp-range=192.168.52.40,192.168.52.50,2h
  dhcp-boot=pxelinux.0
  enable-tftp
  tftp-root=/pxe
  resolv-file=/etc/nameservers
  dhcp-option=3,192.168.52.1

• Make sure you replace the IP with addresses, netmasks etc with ones suitable for your network.
• edit /etc/exports & replace all text with:/pxe/images *(ro,sync,subtree_check)
• Add your DNS nameservers by creating the new file (this is for opendns):
  

  gedit /etc/nameservers

  nameserver 208.67.222.222
  nameserver 208.67.220.220

• Reboot your server
  

Now you can able to boot your target client machine to Ubuntu if it has a pxeboot enabled network card (usually accessed by pressing F12 at boot).

[Ubuntu] Disable screensaver and powermanager while mplayer or other apps are running

 

I was found a small python daemon on other forum site to disable gnome-screensaver and gnome-powermanager while certain specified apps are running. It works quite well on Ubuntu Edgy. It requires dbus (>= 0.93), python-dbus, and obviously gnome-screensaver and gnome-powermanager (on gnome 2.16).

To install it just copy "disablegss.py" in /usr/local/bin, fix its execute permissions and create a simple config file in your homedir "~/.disablegss". In this config file add every application name that could stop gnome-screensaver, one for each line.

For Example:

mplayer
gmplayer
vlc
wxvlc
xine
gxine

Please notice you must insert the name of the app how you can see it on 'ps aux': for example if you want to add firefox, you must write a line with "/usr/lib/firefox/firefox-bin".
Now just launch disablegss.py on a terminal or simply add it on your session!
You can change the config file on fly (I check if someone modify it), adding or removing apps without restarting it.

How Works:

---

 Author's Talks:
Unfortunately the dbus and gnome development documentation are a bit outdated, so I have read totem sources to view which methods are called to stop gnome-screensaver and gnome-powermanager. The idea is if you call the Inhibit method of gnome-screensaver, you disable the screensaver AND the powermanager. To enable them again you must call the UnInhibit method. There is a small terminal app, dbus-send, to comunicate with dbus but it doesn't work well with these methods, so I decide to use the python dbus interface. This is my first program in python so please tell me if something is wrong or not well coded!
Every 60 secs the daemon check if there are apps running that are also present in the config file. If it's true, the screensaver is disabled. If someone change the config file, the daemon read it again.
I don't think that this small daemon could run on Dapper: the dbus and gnome API change on every release. But you can modify it to fix things. There are only two lines that could be problematic:

Line 38: cookie = dev.Inhibit(myprogram, 'Disabled by DisableGSS Daemon')
Line 49: dev.UnInhibit(cookie)

These two methos are different on gnome 2.14 on Dapper. Also dbus has radically changed. If you want to use disablegss.py on Dapper, find the right methods (try to see dapper totem sources) and feel free to change what you want!
To do debug, I suggest you to launch disablegss.py on a terminal and dbus-monitor on another one (you can see all messages from and to dbus daemon). Also change the sleep time value in seconds (line 121) to debug it faster.
Happy coding!

This works very well for me :D , How about you?

The Password Rumour for Ubuntu ;)

Just to know    :)

By default

Ubuntu has a root password; they just don't tell the user what it is.
Some versions claim it is a randomly generated one. There is no root password, and this statement mustn't be confused with "the password is carriage return" (a usage RMS tried to popularize at MIT). Take a look at /etc/shadow, if you will (sudo less /etc/shadow). On a default install, the first few lines will look something like this:

root:*:14438:0:99999:7:::
daemon:*:14438:0:99999:7:::
bin:*:14438:0:99999:7:::
sys:*:14438:0:99999:7:::
sync:*:14438:0:99999:7:::

Contrast this with the line containing your user's name.

test:$6$.XQFA5P3$JYH9CpZS00DUAPDXcxc5qzP
2vaNLrGj2TB5dlLj6rEVCOMpTt5XmFH7eL2TiDtX
GApTknWhO6phpGyuac3DCU.:14470:0:99999:7:::

What is different? The second field (the part after the first ":") is a "*" for those system users and a long jumble of numbers and letters for the human users. The "*" means that the user cannot login using a password. The long jumble of numbers and letters? That is a hash of the user's password. In this test user's case, that is a hash of the string "password". If you're interested in the other fields, see man 5 shadow. This password has been encrypted with SHA-512, as evidenced by the $6$ at the start of the hash. See man crypt for a list of other possible prefixes. Note that $1$ means MD5, a hash which has been rather thoroughly broken. Since 8.10, SHA-256 and SHA-512 are available and will be used if you reset your password. If you've still got an MD5 hash in there, it's likely a good idea to do so, if only because it means you haven't changed your password recently enough.
This rumour usually comes up in the context of someone pointing out that if you are a remote attacker, you can guess that root has all the power and so all that is needed is to brute force root's password. In Ubuntu's default setup, this won't work because there is no password that would succeed, regardless how long you spent generating new passwords to try. Instead, the attacker would need to guess the correct combination of user-who-has-sudo-access and password—something exponentially harder. Well-meaning but misguided folks, attempting to protect us Ubuntu users from a false sense of security, then warn us that no, we're wrong, Ubuntu does have a root password. Well, the evidence is in /etc/shadow for all to see. Ubuntu has a locked root account, just the same as if one were to run sudo passwd -l (see man passwd).

uSbuntu (Ubuntu) Live Creator

uSbuntu Live Creator does almost the same thing as the USB Live Creator included in the 8.10 except it has more features.

It is working with Ubuntu, Kubuntu and Xubuntu and it allows you to run your USB key directly in windows without any software installation nor configuration, using a special portable version of VirtualBox.

It’s really easy to use.

Creating an uSbuntu key is a five easy steps:

---

•  launch the uSbuntu Live Creator and choose a USB key or drive in the list
• select a ISO file or CD of Ubuntu/KubuntuXubuntu 8.10 Intrepid Ibex
• choose the size of persistency data (usually more than 250MB)
• check the options you want
• click the thunder to start the creation

Do not forget to use the customized helps (top-right end corner of each step).

Moreover, each needed step (1,2 and 3) has a traffic light to indicate its state. This is the interpretation

Red light: the step is not correctly fulfilled, you cannot start the creation

Orange light : there is a non blocking problem on the step

Green light : everything’s fine

Easy way to use any DialUP modem Without WVDIAL in Ubuntu/Linux

Ubuntu Vs Windows XP:

---

In the case of internet on Ubuntu/Linux have very high speed compare with windows XP. So nowadays many ppl's are leaving windowsXp to Linux.

Connecting modem without WVdial or others:

---

Here i give an Easy way to use any type of DialUp modems (include mobile phone's) without using WVDIAL or something like that (no need for special drivers).

At now many modem (not only modem, all hardware) manufacture's write driver softwares for only windows. But Ubuntu have a special feature to automatically detect devices that you connect to CPU.

WVdial:
If you connect dialup modem using wvdial It takes very long time to connect, Registering IP ect. and also ubuntu does not detect the network connection even if you are already connected to net (ubuntu always say offline).

Here is a Simple Trick:

---

• First of all connect your modem to cpu.

• At first time click on network icon and select "Auto Mobile BroadBand Connection"

• It will try to connect wait untill it says "you are in offline"

• Then right click on the Network icon and select "Edit Connections"

• Then navigate the Third tab "MobileBroadBand" ther you can find the "Auto mobile broadband connection" doubleclick on it, Now give all needed data's
  
• You all need to give only Dial number,Username,Password. And Apply then close. (Dont edit other things. If your connection does not work remember to come back and edit these settings otherwise don't do anything.)
• Now ubuntu will try to connect the internet. After connected to the internet it will gives an notice 'You are in online'. If not go back to edit connection and check your connection.

I have connected 3 modems EC325, EDvobe CArd, EC620 with different ISPs.

When i am using EC325 modem in Windows it give me a speed 10kbps
But in Ubuntu it gives me a speed 80kbps.

Deleted Linux Partition-Don't worry

I have two OS installed on my computer one is XP another one is Linux. Yesterday i got so many error msg's on my XP related to HDD. So i decied to run CHKdisk on Xp startup.I got ahead of my self and did something stupid, I deleted my Linux partition in windows. When I restarted, I got GRUB ERROR 22. I looked around on net and i found the solution that is boot computer into a Linux live cd and run this command,

"sudo lilo -M /dev/sda mbr"

It will recover linux on your Pc. Now i have both OS's that run's nicely..
