Because my internet connection is very unstable at the moment, I'd like to use a small indicator applet for the Unity panel.

Since I'm connected through a WLAN/Wifi Router, I can see in the network-applet when the connection to the router is lost, but not when the router loses the connection to the Internet.

A Windows 7 computer of mine has this functionality. It shows a black exclamation mark on yellow ground if it can't "ping" a remote server.

I'm running Ubuntu 11.10 "Oneiric Ocelot" 64-Bit with Unity 3D.

Whilst you mentioned you wish to do this in the network applet - I don't think you can do this. Here is an alternative.

internet up

enter image description here

internet down

enter image description here

how to for 11.10 & 12.04

It requires an indicator from a PPA together with a custom ping test script:

sudo add-apt-repository ppa:alexeftimie/ppa
sudo apt-get update
sudo apt-get install indicator-sysmonitor
mkdir -p ~/scripts && cd ~/scripts

using:

gedit pingtest.sh

Copy and paste the code below into the new file and save & close.

Give the file execute permission:

chmod +x pingtest.sh

Start the indicator

indicator-sysmonitor &

Then in the indicator-preferences:

enter image description here

click "use this command" and copy and paste the following text:

$HOME/scripts/pingtest.sh

code

#!/bin/bash

if ping -c 1 -W 2 google.com > /dev/null; then
 echo "Up"
else
 echo "Down"
fi

This could be easily modified for Website Monitoring, wish i could +2! –  Lewis Goddard Feb 22 '12 at 12:53
    
@fossfreedom, 1. What application did you use to draw those arrows on the images? 2. Does it still work on 14.04? indicator-sysmonitor isn't available in that PPA! –  mini Apr 23 at 17:51
    
@Kin - that is with Shutter! I've created another answer for 14.04. Hope that helps you. –  fossfreedom Apr 23 at 20:33

The original answer was written for Ubuntu 11.10 & 12.04.

Since then, the indicator interface was changed for 12.10 & 13.04. However, the maintainer has not released a version since then for later Ubuntu versions. No code commits in the launchpad PPA has been made since first quarter 2013.

Thus I have forked the project, fixed a few bugs and made it available for 14.04 Trusty users. Feel free to check out the code on GitHub and help out with the maintenance.

Then in the indicator-preferences click New:

Then enter the details as shown:

i.e. use the command

$HOME/scripts/pingtest.sh

Click OK, followed by the following actions 1,2,3 & 4:

I've been using Manjaro since a while now, so I can't test the solution, but I'm sure it works ;) Thanks! –  wintersolutions Apr 23 at 21:24
