ddclient is available as a tarball. While I'm fairly computer savvy, I'm a novice when it comes to linux. Since my only computer is a windows based laptop, how can I unpack the file? Should I download it directly to my my n770? Also once unpacked, do I copy all the files to usr/bin/ddclient or are there other folders that need to be created? And finally, once all the files are copied over, do I execute the app by using filemanager and doubleclicking the main file (I'm assuming the program won't appear as an installed app)?
