All bechmarks were performed inside LAN and on 65K ports.
Usage:
NimScan <host | IPs> -p:<portX>-<portY> [--timeout=<time>] [--files=<limit of file descriptors>] [-a]
NimScan <host | IPs> -p:<port>
NimScan <host | IPs> -p:<port1>,<port2>,<portN>
NimScan (-h | --help)
Options:
-h, --help Show this screen.
-p, --ports Ports to scan. [default: 1-65,535]
-a, --all Use rawsockets to find filtered/closed/open ports (Takes longer and limited to 10,000 ports).
-t, --threads Number of threads per scan.
-f, --files=<limit> File descriptors per thread limit.
-i, --ignore Ignore ping latency check.
--timeout=<time> Timeout to add to the latency [default: 1500].Scan range between 1 to 5000 ports
NimScan 10.0.0.0/24 -p:1-5000 Scan specific ports
NimScan 10.0.0.1-10.0.0.10 -p:80,443,445Show closed/filtered/open using rawsockets
NimScan.exe 10.0.0.69 -ascan(char * host, int * ports, int size);
scanner(char * host, int * ports, int size, char * parameters);- host - IP/HOST to scan
- ports - Ports to scan
- size - Size of ports array
- parameters - Parameters to give for the scanner as mentiond above under Usage
#include <stdio.h>
int main(void)
{
NimMain(); // A MUST!
int ports[] = {1, 445, 8080, 3389, 135, 139};
int size = sizeof ports / sizeof ports[0];
scan(<IP/HOST>, ports, size); // Scan given ports with default configuration (timeout = 1500ms, files = 5000)
scanner(<IP/HOST>, NULL, 0, "<arguments>"); // Scanning all 65K ports with given arguments
return 0;
