Question: Port Scanner and IRC botnet

[Clone]

I have tried the port scanner out but it doesn't seem to work ,I thought it was the AV but nah! its my first time dealing with  winsock socket programming and I might say windows based progarmming is like math classes  ... so many functions,structs,data types  aaaah! but thats not for today  ......here is my code:

Code: (C++) [Select]


#include <iostream>
#include <winsock2.h>
#pragma comment(lib,"ws2_32.lib")
 
char TargetIp[256];
unsigned int Start_P,End_P,Current_P;
 
int main()
{
    std::cout<<"\t\tPort Scanner\t\t\n";
    std::cout<<"\t\t-------------\t\t\n";
    std::cout<<"Enter target IP address:";
    std::cin>>TargetIp;
    std::cout<<"Enter start port:";
    std::cin>>Start_P;
    std::cout<<"Enter End port:";
    std::cin>>End_P;
    if(Start_P<End_P)
    {
    std::cout<<"Error:Start port needs to be less than End port.\n";
    exit(0);
    }
    else{
 
 
    // Initialise Winsock
    WSADATA WsaDat;
    if(WSAStartup(MAKEWORD(2,2),&WsaDat)!=0)
    {
        std::cout<<"Winsock error - Winsock initialization failed\r\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }
     
    // Create our socket
    SOCKET Socket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
    if(Socket==INVALID_SOCKET)
    {
        std::cout<<"Winsock error - Socket creation Failed!\r\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }
 
    // Resolve IP address for hostname
    struct hostent *host;
    if((host=gethostbyname(TargetIp))==NULL)
    {
        std::cout<<"Failed to resolve hostname.\r\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }
 
    // Setup our socket address structure
    SOCKADDR_IN SockAddr;
    SockAddr.sin_port=htons(8888);
    SockAddr.sin_family=AF_INET;
    SockAddr.sin_addr.s_addr=*((unsigned long*)host->h_addr);
    for(Current_P=Start_P;Current_P<=End_P;Current_P++)
    {
 
    // Attempt to connect to server
    if(connect(Socket,(SOCKADDR*)(&SockAddr),sizeof(SockAddr))!=0)
    {
        std::cout<<"Failed to establish connection with server at port "<<Current_P<<"\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }
 
    else
    {
        std::cout<<"Port:"<<Current_P<<"is OPEN"<<std::endl;
    }
    }
    // Shutdown our socket
    shutdown(Socket,SD_BOTH);
 
    // Close our socket entirely
    closesocket(Socket);
 
    // Cleanup Winsock
    WSACleanup();
    }
    system("PAUSE");
    return 0;
}

In addition to that ,I was learning about botnets so that I at least help out my fellow botnet noobs but got errors.
The code is from the youtube video by julian search it ...I only tried to clone it and understand its structure but it seems i need expert advice  on botnets coding for windows.NB: Ez admins don't take the bot target address serious i wasn't try to cause harm.Its just an example.

I would appreciate it if any one would point me to a good beginners guide to c c++ win32 programming

The bot is incomplete, it doesn't complete the IRC PING/PONG challenge. Not only that, even if you did reply, your bot would stop working because it doesn't PONG for every PING it receives. Not to mention, it doesn't join a channel, and has no functionality programmed in it to interact with the channel.


Try to take this as constructive criticism, but...your skills are not developed enough to take on a project such as this. Continue learning to program, and understand how computers work in general. I know you're eager to learn how to get these working, but come back to them when you know more.

True enough but the guyz here don't help at lot its always go do more.....work harder..... but maybe a pointer to source or a reference to sample codes or a tut or whatever the likes would be
 a bit better.

Thanks chief! 

Code: [Select]

int  Ez gurus=100%;
int  Clone=0%;

while(Clone<=Ez gurus)
{
Clone+=Ez gurus;
}

I must really suck at programming to be given this tut...https://evilzone.org/c-c/c-tutorial/    well I guess I am not like you guyz who begun programming at 10yrs old....I need to take some time off Ez and work hard maybe come back later on in life. It was fun though sure learnt lot though.

Staff note: no double posting pl0x!

If that's what you want. But i think you can also learn while being a bit active on EZ. That is what i do. Just keep the learning going and then sometimes take a look on EZ and comment on some post. You don't have to be very active all the time. But if you want to come back in a year that's also fine.
