I have Ubuntu OS in my system(laptop). There are situations when I want to transfer files from my tab3 to my system through bluetooth in IIT. As all the systems in IIT are configured with Ubuntu OS, all system names are 'ubuntu-0'. It is quite confusing as to which system my tablet is getting connected.
So I changed my system's name. The procedure to do so is as follows:
1. Open your terminal
3. sudo gedit config
4. change name 'ubuntu-0' to anything you wish.
5. close the file
6. Reboot the system
