It signifies that although Nmap was able to finish a TCP handshake with the target system, the target system actively refused the connection when Nmap states that a port is in the âclosedâ or âconn-refusedâ state. This could indicate that no service is listening on that port or that the target systemâs firewall is preventing the connection.
Ports that are deliberately excluded from the scan using the ââexclude-portsâ option or by the target systemâs firewall preventing the connection are referred to as being in the âignoredâ state in Nmap, which does not provide any information about the portâs status.
Itâs likely that some of the ports Nmap lists as âignoredâ are truly closed or filtered; however, Nmap was unable to ascertain their status because of the scan settings chosen or the target systemâs network configuration.
You can experiment with various Nmap scan options and approaches, such as UDP scans or version detection (-sV) to identify certain services operating on the target system, to gain a deeper understanding of the target systemâs network topology and services. To learn more about the target system and its services, you can also try using additional network reconnaissance tools.
I have the same issue, the vpn is correctly setted i can ping the machines but when I try to nmap the ports are in ignored state, I tried to change the network interface of the vm and I tried to disable my gateway firewall but nmap still doesnât work. Did you manage to solve it?
I have this problem with this machine too (Redeemer). I think that it has a problem. Use the next command pointed in the âwalkthroughâ and continue the machine
I found a solution using the -Pn flag to disable host discovery since weâre just scanning for open ports. Additionally, use the --min-rate option because the scan will be extremely slow without it.
