Sometimes an IT Administrator need to work anytime and averywhere to manage or control computer devices or servers that exist by remote desktop sharing. Especially if there are disturbances and the position we're not at the office, while the device is experiencing problems can only be accessed by the office's internal network only, it required a VPN (Virtual Private Network) so that we can get into the office's internal network via a network connection from anywhere, VPN is Another Solution for Linux Administrator.
VPN solutions are now widely available, either provided by your ISP or a software. In tis article i want to review ubuntu remote desktop sharing using by software called "TeamViewer", Teamviewer is work using VPN Connection and can be use cross platform or cross operating system. Teamviewer software is available for windows and linux, to install Teamviewer in ubuntu you can visit their official website and download it here: http://www.teamviewer.com/download/index.aspx. This software is free as long as not used for commercial purposes. TeamViewer also provides a paid version of the course with more features than the free version. Teamviewer works by creating a pear-to-pear between 2 pieces of host or client, Install Teamviewer on the computer within the internal network that we want the remote, then other computer that will perform remote must have internet connection and off course Teamviewer ready. look following exampletoperform ubuntu remote desktop sharing using Teamviewer VPN. I'm using Linux Ubuntu 10.10 and I am going to a remote target is a PC with Windows OS. How to install Teamviewer in ubuntu is just type command above in the terminal:
$ Sudo-i teamviewer_linux.deb dkpg
Once completed in our live install just run from the menu in Ubuntu: Application - Internet - TeamViewer
Teamviewer screenshot
Each TeamViewer will have a unique fixed ID for every 1 computer. and will also generate a password each time you run the software. Well next, make the TeamViewer remote ID on your computer that will be remote. Live input only opponent ID and password then click "connect to a partner"
Teamviewer remote desktop sharing
In terms of security this software is somewhat vulnerable because of its simplicity to use. If we do not want to allow this software running on the internal network, maybe you can block the port and its domain from the side of the firewall. Yep .. That is Another Solution for Linux Administrator who want to perform remote desktop sharing using VPN, i hope this will help .. :D

Ubuntu Tweak is an application to config Ubuntu easier for everyone. It provides many useful desktop and system options that the default desktop environment doesn't provide. With its help, you will enjoy with the experience of Ubuntu. Ubuntu Tweak popped out a new release one stuffed full with some great new features. It is a bug-fix version coming with a lot of PPAs update.Initial support has been adeded for Ubuntu 11.04 Alpha, including Compiz settings pre-Natty users will be familiar with (E.g. Workspace Edge Settings, Desktop Effects and Menu Effects.)
Enable workspace switching using mouse scroll wheel. We’ve covered five ways to switch between workspaces in Ubuntu a few months back. Now we’ll have to make that six ways to switch now that Ubuntu Tweak has added a single-click solution to enabling “Workspace switching with mouse wheel”. Once enabled click on a blank part of the desktop and scroll up or down to roll on to the the left next workspace.
MeMenu tweak Fed up of seeing your ‘username’ in the MeMenu? Help is at hand in this release; a new option, Me Menu Setting, gives the ability to swap between real name, user name or no-name at all in the MeMenu area. Helpful helper is helpful Lastly is the addition of a ‘system error’ helper that, rather than bleating on that something is amiss, actually offers up assistance in fixing the problem.
Ubuntu tweak 0.5.8 can be downloaded in this link.
Warning: During installation, there is an advanced option (Ready to install -> Advanced) to install the GRUB2 bootloader into the same partition into which the (K)Ubuntu OS is installed but not to change the MBR (Master Boot Record). Pay careful attention during this step if your system uses a boot partition, uses multiple OS (more than 2), or chainloads bootloaders. For systems with such a boot partition, it is best not to overwrite the MBR.
* Example, from the Desktop version GUI installer, a point in the installation will be reached:
Summary -> Advanced -> Device for boot loader installation: /dev/sda6
Mac Os on Ubuntu
In this example, this setting will cause the GRUB2 bootloader to be installed into /dev/sda6 only (the partition into which the new (K)Ubuntu OS is being installed). The MBR (Master Boot Record) will not be changed. However, if the default setting of /dev/sda is allowed, then GRUB2 will not only be installed into partition dev/sda6 (into which the (K)Ubuntu OS is installed) but also the MBR (MasterBootRecord) will be changed so that the copy of GRUB2 stored there will be designated as the master bootloader for all Operating Systems on the entire computer. This may be undesirable if you wish to use bootloaders other than GRUB2.
If you want to install more than 2 operating systems on a single computer, check out these tips. Use Startup Manager to change Grub settings Grub is the bootup utility that controls which OS to load by default and other bootup settings. You can change Grub settings from the Startup Manager:
System -> Administration -> Startup Manager
If Startup Manager is not installed, install it:
sudo apt-get install startupmanager
Note: You can also edit the Grub settings manually from the command-line interface.
Dual-Booting Mac OS X and Ubuntu Mac OS X has a similar structure to Linux (it is BSD Unix based). Dual-booting Mac OS X and Ubuntu detailed instructions can be found here.
Installing Mac OS X after Ubuntu if you decide to dual boot with OS X, choose ext2 as your partition type during the Ubuntu installation. (For this the Super Grub Disk CD is a useful utility. You can download the Super Grub .iso image file at forjamari.linex.org and burn the image to a CD-ROM.)
* Once you have installed Ubuntu, edit the Grub start-up list:
sudo nano /boot/grub/menu.lst
and add the following lines:
title Mac OS X root (hd0,0) makeactive chainloader +1
Reboot your Mac and go to the terminal in Max OS X (if you have any issues booting, boot from your Mac OS X DVD). Press F8 and enter -s. Enter:
fdisk -e /dev/rdisk0 flag 2 <--note that flag 2 is my Mac partition number two quit y reboot
If are still unsure whether it is working correctly, use the Super Grub Disk CD and make grub active. Installing Ubuntu after Mac OS X If you get an error message during boot such as HFS+error in the bootloader, you can also use the Super Grub Disk for recovering Linux GRUB and the Windows MBR (Master Boot Record).
* Once you have installed Ubuntu, edit the Grub start-up list:
sudo nano /boot/grub/menu.lst
and add the following lines:
title Mac OS X root (hd0,0) makeactive chainloader +1
If you have issues with Mac OSX or Windows in GRUB, try changing the Mac OS X Grub entry
Whatever operating system (O/S) had installed, one of important jobs they must can do is "work every where, work any where", in this part we will stress our topic with how to let our printer use by other (sharing) via CUPS (Common Unix Printing System). The Common Unix Printing System, allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer. For Example we will use Printer HP Laser Jet 1020 as object:
Go to System> Administration> Printing Printing after a window pops up then click Servers> New> Printers and follow the picture below
Step 1
Choose Windows Printer via SAMBA, then click the Browse button then it will continue the process of scanning ... select the printer that has be shared and then click OK.To ensure click the Verify button and make sure the dialog box Print Share Verified exit. Then click Forward
Step 2
Select a vendor for printers that have been sharing and click Forward
Step 3
Selecting brands of printers ...
Step 4
Give a identification to the new printer…
Step 5
The installation process successfully. Will do a test print? Yes to print, not to reject ...
Step 6
It's all procedure we must do to share printer via CUPS on Ubuntu 10.04, It's quite similar to do this jobs in most distriburion like Ubuntu, blankon, Mandriva, OpenSuse. Good luck ..
