If you have ever used the popular software InSSIDer on Windows or OS/X, you might wonder if there is an equivalent application for Ubuntu/Linux.
LinSSID allows you to visually survey the Wifi networks in your area, identifying networks using the same channel as your own, even if they are not broadcasting SSID’s.
sudo add-apt-repository ppa:wseverin/ppa
sudo apt-get update
sudo apt-get install linssid
— OR —
sudo vi /etc/apt/sources.list
deb http://ppa.launchpad.net/wseverin/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main
NOTE: it seems that the release version is only available for ‘precise’ and has not been updated for newer Ubuntu releases, I was able to simply go to the terminal and execute "
software-properties-gtk" to change ‘trusty’ to ‘precise’ on the PPA and it worked great!
After a clean install, or simply access to a new machine, I often find it helpful to enable colored prompts in the terminal/command line environment.
For standard Ubuntu / Debian / Linux environments, this only requires you to remove a comment from a single line in a config file.
/home/%USERID%/.bashrc you will find the following text, the last line simply needs to have the hash removed:
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
Open vi/vim or your editor of choice and remove it and you are done!
NOTE: If you are using Nautilus, you will not see this file as it is hidden, choose “View”, “Show Hidden Files” (CTRL-H) and it should appear.
Most operating systems make this rather trivial to expose, Apple seems to have made it just a tiny bit more difficult… as such, I provide the simple steps here for my own memory as well as your benefit.
WARNING: Be particularly careful about the files you modify or delete, you could impact your system in very critical ways… there is a reason they are ‘hidden’, most often it is to keep less-technical users from breaking things 🙂
Return hidden files to their usual state.
