How To Use Netcat Command

If you want to check the Netcat is really working or not. You can check if a port is opening on a remote or local machine. For example, we check the port 80 and 443 on a web server.

PS C:\> ncat -v -n 10.10.5.88 80
Ncat: Version 7.80 ( https://nmap.org/ncat )
Ncat: Connected to 10.10.5.88:80.

PS C:\> ncat -v -n 10.10.5.88 443
Ncat: Version 7.80 ( https://nmap.org/ncat )
Ncat: No connection could be made because the target machine actively refused it. .

Another example of Netcat. We’ll check if an UDP port is opened on a remote host. By default, Netcat checks the TCP only, show we need to -u to use UDP instead of TCP.

PS C:\> ncat -v -n -u 103.1xx0.2xx.2xx 5060

Ncat: Version 7.80 ( https://nmap.org/ncat )
Ncat: Connected to 103.1xx0.2xx.2xx:5060.
