some cool terminal commands to check your network connectivity and active handle processes.
in Linux Mint already brings top command installed
top
utility to show active processes with refresh update
not installed but yet useless
iftop
sudo iftop -t > log.txt
utility to show all servers connected to your network in Real Time
best of this utility is:
you can create log file to record all internet session and with that;
- identifying what it looks suspecious
) - you can search what it is and what location it whereafter that, you can block in /etc/hosts , editing and adding the entry just like:
127.0.0.1 http://www.something else.com or 127.0.0.1 239.255.255.255
127.0.1.1 idem
and save it
quit session or better reboot the system.
MY ADVICE
record all the network output everytime you start using, and save the file with the day.
