Use your Android phone to control your Linux machine

 Use your Android phone to control your Linux machine

 If you watch lot of videos on your big computer monitor by sitting at some distance away from screen, it becomes a pain to get up each time and change the videos. Sometimes i wished I had a remote control for my computer. I  found that i could use a tool called WiFi Mouse to operate my computer remotely from my phone. This post is about how i could successfully configure and use WiFi Mouse. I am using WiFi mouse on an Android phone, but according to WiFi Mouse website Apple products like Iphone and Ipad are also supported. Using WiFi Mouse i could use my phone as mouse as well as keyboard for my computer. The user interface of  WiFi Mouse is pretty intuitive and easy to use. The only issue i found is that it is not supporting letters in CAPS when using keyboard mode on the App.

Steps to configure Android phone as remote control / remote mouse for your Linux machine

• Ensure that both the computer and phone are connected to the same network. My phone is on wifi and Linux system is connected to the LAN port on the same router. The router must always be "ON" for using the tool.
  
• Download WiFi Mouse App on your Android phone.  
• Install Mouse Server on Linux machine. My machine architecture is  64 bit and i use openSUSE and hence I downloaded and installed this rpm. You can check about Linux architecture using this post. You can create a local repo and install rpms using this post.
  
• Restart the Linux machine to ensure that Mouse Server has started up .
• Open  TCP port 1978 on the Linux Firewall. Check out this post for opening firewall.
• Now open the Wifi Mouse App on your phone. It will automatically show your computer / Linux machine if the Mouse Server is already running.

Getting FatRat installer:-
Assumptions:-
==>You are on GNOME 3.2.1
==>You are using openSUSE 12.1
First you need to determine the OS architecture(32 or 64 bit).
==>To do this you can open terminal(press Alt+F2 and type in "gnome-terminal" and hit return or enter key)
==>In terminal execute the command "arch". It should give you output like "i386" or "i586" or "i686" [32 bit] (Or) "x86_64" [64 bit]
Based on the architecture the relevant package must be downloaded.

My Output:-Indicates that I have a 32 bit OS installed.

Optional(Will Make Things Easier):-Next we add Enzokiel repository and install Oracle / Sun Jre from that repo. Look under "Configure repository using URLs" subheading under this post will help you do that.This is needed to check the dependencies for FatRat and download them too.
The following steps explain as to how to get the required packages to install FatRat:-
==>Navigate To  rpm.pbone.net
==>Search for fatrat package or software

==>Locate the appropriate version depending on your OS type as explained above.
==>Since I use a 32 bit OS I have downloaded fatrat-1.1.3-4.fc15.i686.rpm

==>If you have installed Sun Jre as described some lines above you can click on check requires link and get the other required libraries that  need to be installed.

 Accept and Run,this step will work only if you have installed Sun/Oracle JRE,as described in the "optional" subheading described above.

==>FatRat 1.1.3 requires three more libraries:- boost-date-time,boost-filesystem,boost-system . The downloaded libraries/packages/rpms would be
boost-date-time-1.46.0-3.fc15.i686.rpm ,  boost-filesystem-1.46.0-3.fc15.i686.rpm , boost-system-1.46.0-3.fc15.i686.rpm

Installation Using YaST (GUI):-
==>Create "Create a repository out of your  Local Directory" using this post
==>Then check the check boxes of the required software in YaST as shown below and hit "Apply"

Installation using zypper (CLI):-
==>Open the terminal (type in "gnome-terminal" and hit return or enter after pressing Alt+F2 key combination)
==>Navigate to the directory of the where your package or rpm is present using cd <space><dirname>
==> Execute the command :-
"sudo zypper in boost-date-time-1.46.0-3.fc15.i686.rpm boost-filesystem-1.46.0-3.fc15.i686.rpm boost-system-1.46.0-3.fc15.i686.rpm fatrat-1.1.3-4.fc15.i686.rpm"
Note:- You may need to enter admin passcode when prompted and press y when it asks you whether it can install so and so software.
Sample output for zypper installation:-
anonymous@linux-9p85:~> pwd
/home/anonymous
anonymous@linux-9p85:~> cd /home/anonymous/Software
anonymous@linux-9p85:~/Software> sudo zypper in boost-date-time-1.46.0-3.fc15.i686.rpm boost-filesystem-1.46.0-3.fc15.i686.rpm boost-system-1.46.0-3.fc15.i686.rpm fatrat-1.1.3-4.fc15.i686.rpm

Easy Way To Step Up Your Torrent Download Speed

This is a very simple trick to improve the speed of your current torrent download.The basic thing behind torrent downloading is that each downloader will in-turn be an uploader(in the strict sense offcourse,don't want to talk about leechers"worst scum on planet").

All you have to do is copy your torrent "hash" code and type in a search engine of your choice,and voila you get many trackers which logically must have more seeders.Then all you have to do is add the new trackers to your already downloading torrent.It is as simple as it gets.In case of "uTorrent",if you open the ".torrent" file with it it will ask you whether it can add the new trackers automatically,don't know much about other client where you may need to manually add the new trackers to your clients.
