What IP’s are connected to your webserver
I found this command a long time ago, and I forgot where. But, I wanted to share it with everyone. It will tell you what IP addresses are connected to your web server, and how many connections there are.
netstat -ant | grep \:80 | awk '{ print $5 }' | awk -F \: '{ print $1 }' | sort | uniq -c | sort -n
Note: Again, I don’t remember where I found this, and you are the author please let me know and I will link it back to you.
