Usage

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].

Examples

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:80,443,445

Show closed/filtered/open using rawsockets

NimScan.exe 10.0.0.69 -a

C/C++ Library 🧑🏻‍💻

Guide

Exported functions

scan(char * host, int * ports, int size);
scanner(char * host, int * ports, int size, char * parameters);

Options

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

Create

#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;
}

Compile

Make sure NimScanToC.a is in your program's folder.

gcc <file>.c -L. -l:NimScanToC.a -w -o NimScan.exe

raiseOSError error!!

I run this script on my ubuntu machine. and this script shows some errors. Why this error?

Error: type mismatch in param_parser.nim(110, 39)

compiled using the command
nim c \NimScan-master\NimScan.nim
with the latest nim compiler (1.6.4)
and got the error:

NimScan-master\modules\param_parser.nim(110, 39) Error: type mismatch: got <string, string>
but expected one of:
proc calc_range(subnet: string): seq[string]
first type mismatch at position: 2
extra argument given
1 other mismatching symbols have been suppressed; compile with --showAllMismatches:on to see them

expression: calc_range(range1, range2)

cidr range is off by 1

The cidr range for 192.168.1.1/25 should include 192.168.1.1 to 192.168.1.127 inclusive.
In file ip_seg.nim, the line last[3] = $(last[3].parseInt() -1) excludes the final value and should be last[3] = $(last[3].parseInt()).

This fix would allow a single IP in cidr notation (192.168.1.1/32) and correct the range to include the last ip in each cidr range

Doesn't work on windows xp and windows 2000

windows xp:

could not import: inet_pton

windows 2000:

could not import: getaddrinfo

Compile New Version: undefined reference to 'scan' and 'scanner'

Hello,

It seems that the instructions of compiling the new version are not correct. I tried the command you listed in your README.md and also looked at the test.c, but failed to compile. You could provide me with the latest .exe or update the README.md please?

Using Kali Linux latest nim and gcc package installed.

Why is it slower than RustScan?

I want to know where the performance bottleneck is.

cannot find module

NimScan/modules/globals.nim(5, 28) Error: cannot open file: OSDiscovery

Can the output form be improved? For example, (ip:port) open

I like this port scanner very much, it is fast and accurate, but the output format is not very friendly

It would be nice to support SOCKS/HTTP proxies

wher is exe cant find even in readme?

Can read IP from the file for scanning?

fix this

oserr.nim(94) raiseOSError
asyncfutures.nim(372) read
asyncfutures.nim(372) read
Error: unhandled exception: Too many open files [OSError]
oserr.nim(94) raiseOSError
asyncfutures.nim(372) read
asyncfutures.nim(372) read
Error:

Awesome!

Nice port scanner. Nim looks like an awesome language too! :)

oserror

when i start the nimscan.exe on windows cmd webshell,somewrong happend ;
like #nimscan.exe -o:result > output
can resolve it ?

import regex error

i have trouble install it

i have no idea how could pack it up to an exe.
my try in test.c :
scan(IP, ports, size); // Scan given ports with default configuration (timeout = 1500ms, files = 5000)
scanner(IP, NULL, 0, ""); // Scanning all 65K ports with given arguments

However ,everytime it comes to :
test.c:19:10: 错误：expected expression before ‘<’ token
it seems that IP/Host havn't been clained, may i get u help?

Can I export scan results to a file？

Compilation error on Linux ARM platform due to undeclared identifier LPCST

I am trying to compile a Nim software on a Linux ARM platform, but I am encountering a compilation error related to an undeclared identifier LPCSTR in the file ip_seg.nim. The error message is as follows:

/root/nim/NimScan/modules/ip_seg.nim(12, 25) Error: undeclared identifier: 'LPCSTR'

After investigating the issue, I found that LPCSTR is a Windows-specific data type that does not exist on Linux systems. It seems that the code in ip_seg.nim is referring to Windows API related headers, which is causing the error.

I would like to request help in resolving this issue. Is there a way to make the code cross-platform compatible or to use Linux-specific headers instead of Windows headers? Any guidance on how to proceed would be greatly appreciated.

Thank you for your help.

Unable to compile?

Tried gcc test.c -L. -1:NimScanToC.a -w -o NimScan.exe

came up with heap of errors

is this the right command?
