Azure VPS Port-forwarding

[qGodless]

I freshly opened port 80, but when I try to listen (same as metasploit)
nc -lvp 80 nc: Address already in use
Is it possible to stop using the Address, while keeping it open

Only one program can bind port on interface at a time.
If nothing listens port, it will be closed.

You may kill the running processes on port 80 by this command.

lsof -t -i:80 | xargs kill -9

and you can check running also by this:

ps aux|grep http*

check your open ports using command below:

sudo netstat -ntlpu

 

[qGodless]

lsof -t -i:80 | xargs kill -9

Solved!!
Turns out, I could use Metasploit's exploit module as a port opener
