how to check open ports of bunch of website at once with nmap/linux?
- by austin powers
hi ,
I want to use nmap in such a way that I could check bunch of server's port at once for checking whether their particular port is open or not?
right now I have 10 ip addresses but in future this could be more .
I know the very basic command in linux like cat/nano/piping
but I don't know how can I feed to nmap the list of my servers to open them one by one and return the result.
