Netcat offers us an opportunity to transfer files from one device to another over a network. Run the following command to grab the target’s ftp and ssh banners: nc 192.168.1.105 21 nc 192.168.1.109 1234įrom the below image you can see that the connection has been setup and both the machines are now able to communicate with each other.īanner refers to a text message received from the host with information about the open ports and services along with their version numbers. Now it’s time to setup an initiator, we’ll be doing this from the Ubuntu’s root user, by simply providing the IP Address of the system where we have started the listener followed by the port number. Run the following command to do so: nc -lvp 1234

Initially, kali’s root user needs to set up his netcat “listener” over a specific port, to build up a network connection. Let’s check out this scenario, where two users with different operating systems communicate with each other over a Netcat established connection. As soon as this connection is established, the communication can be done from both ends. To set up this all, we’ll be using two devices – one will play the role as an initiator and the other one will be a listener. But before that, we need to establish a connection. Netcat can also be used to chat between two users. From the below image you can see that we’ve captured the running “snmp” service. In this scenario, we have mentioned the port number rather than the range.

Here we’ll be using the “–u” flag which will invoke the UDP mode. We can even scan the UDP ports in a similar way we scanned the TCP ones. From the below image you can see that I’ve mentioned a port range of 21-100, which will dump the running services over the target’s machine. In order to complete this scan, we need to specify a range of ports. Thus netcat can perform both the TCP and the UDP scan, let’s check it out how: This makes it possible to understand the type of service that is running on that specific port. To make it worth as a scanner, we need to set the “-z” flag, which tells netcat, to scan listing daemon without sending any data. Netcat can be used as a port scanner, although it was not designed to function as. To start with netcat, we’ll be using the most basic help command i.e. “Help” or sometimes its “h”, this flag drops out every possible option that a tool can do for us. Let’s try to dig deeper and explore what we can more do with this great tool. So uptill now, you might be aware of all the features that Netcat has, which makes it unique and simple.
