I’ve heard JP mention the tail command that allows one to watch attempts by outsiders to enter the ports of one’s computer. I tried reading up on how to use it. Does anyone have a link to a simple explanation of it or a video showing how to launch it in the terminal? It seems that one has to pick certain variables to make it run, but I’m not quite certain how that works. Any info appreciated.
Here you go:
The command is simple. Open up the terminal you wish to dedicate to monitoring and type in:
cd /var/logs tail -f syslog
And let it go. Anything that happens on your system will appear immediately there. You can leave that window open and the command will keep you informed. You can exit it at any time with CTRL+C.
