What network related software is used to check for opened ports?

Answer 1

Port scanner

Answer Explanation: To help assess vulnerabilities relating to a network's security, use a port scanner. Port scanners are used to look for open ports on a network host. Port scanners can detect computer network services that a remotely located system is providing.

Answer 2

For both Windows and Linux, the command is 'netstat'. To find out if you have any open ports (all PCs do to some extent), you can do a 'netstat -na' and look for any lines that have the word "LISTEN" in the last column.

In Linux, you can do a 'netstat -na | grep LISTEN' to only view those ports, disregarding the others.
