Unicornscan and Comparison with nmap

Unicornscan is another port scanner tools and it works similar to nmap. Let's take a look.

The syntax for unicornscan is: unicornscan [option] [target host]. First, i use unicornscan to my laptop as the target (192.168.1.100) and this is what i got.

To ensure what i get is same, i use nmap and compare the result.

From the result, there is some difference between nmap and unicornscan. nmap is show more complete result rather than unicornscan (not as complete as nmap) and for nmap, there are one filtered port shown and unicornscan didn't. 

For next one i will use TCP scan and this is the result.

And i compare it with nmap too.

The result still same like the previous example so next i will use UDP scan for next example.

Using UDP scan, this is the result for unicornscan.

Using -v (verbose) will show all the ports that will be scanned, network interface and some info and time. The result shows 2 UDP open ports and some error message. From what i get, it is defunc, means it is not supported anymore.

Now i will compare it using nmap -v -sU (UDP scan) and this is the result.

For nmap, using -v not shows the list of scanned port and from the result, there is a different. unicornscan get 2 open ports (69 and 137) while nmap only 1 open port (137). 

We also can use some specified port to be scanned, for the example, i use TCP scan for port 21,25,80,100,443 and this is the result.

Another option that i use is sniff (--sniff). For the last, i will do sniff to my laptop as the target.

Using sniff we can get the packet information like window size, packet length, checksum and others.

In conclusion, i can say that nmap is better choice for port scanning. unicornscan actually can be better but there is no update after 2007 until now. For the speed, unicornscan is faster than nmap because based from UDP scan, nmap takes about 11 seconds and unicornscan takes about 7 seconds or more.

For port scanning, always make sure to use more than one tool because from my result unicornscan UDP scan gives complete result than nmap.
