?A small footprint network usage tool that works like a charm with SD-WAN
In 2001, an Australian wrote a tool named darkstat. That is around the same time token-ring went titsup. 20 years later the tool is still useful for troubleshooting and determining network usage. Its biggest benefit is that it has a small footprint and is light on resources. By default it does not write data to disk. This is different to other similar solutions that kill a system.
The following install and configures the tool on a debian system.
sudo apt-get install darkstat sudo nano /etc/darkstat/init.cfg START_DARKSTAT=yes INTERFACE="-i eth0" DIR="/var/lib/darkstat" DAYLOG="--daylog darkstat.log" sudo systemctl start darkstat sudo /lib/systemd/systemd-sysv-install enable darkstat sudo systemctl status darkstat
If the firewall rules are correct, then self contained web page of the tool will be available on port 667. It has more than sufficient information to determine what is happening at a remote location.
