I'm trying to modify one of my extensions that shows network traffic from my computer (For an indicator). I'd like to be able to quantify how much of the network traffic I see is coming/going to the internet, and how much is exchanged with my local subnet.
Is there any way to make this distinction in Ubuntu using e.g. netstat?
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
internet down
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:
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
In versions before 1.4.2, 10.42.0.x is hard-coded into NetworkManager. Forget about GUI-based solution or wait until the bug/feature request is fixed. Or fix it yourself for all of us. Or at least vote the bug on launchpad for faster resolution.
Either upgrade to Ubuntu 17.04, with version 1.4.4, or use the following command from Thomas Haller to set the host IP and class.
nmcli connection modify $CONNECTION_ID +ipv4.addresses 192.168.5.1/24
where $CONNECTION_ID if found via nmcli connection show. Afterwards, verify with nmcli connection show $CONNECTION_ID.

Assuming you could obtain current network traffic, broken down by subnet, and put that process into a shell script, you could then install indicator-sysmonitor and add your script to the indicator.
I also happened upon bandwidthd which may help.
