使用Ruby模糊FTP服务器
嘿，我是Ruby的新手，并试图通过将一些编程从一种语言移植到另一种语言来学习。现在我正在使用Ruby中的FTP模糊器来镜像这个perl脚本：
use Net::FTP;
$target = "192.168.37.128";
$buffer = "Ax20";
$buffer .= "A" x 512;
$ftp = Net::FTP->new($target, Debug => 0, Timeout => 5)
or die "Cannot connect to $host: $@ n";
$ftp->login("anonymous",'anonymous@nowhere.com')
or die "Couldn't log in: $@n";
$ftp->list($buffer);
$ftp->quit;
require 'net/ftp'
buffer = 'Ax20'
buffer = (buffer + ('A'*512))
ftp = Net::FTP.open('127.0.0.1','anonymous','anonymous')
ftp.login
ftp.list(buffer)
ftp.quit

require 'net/ftp' ftp = Net::FTP.open('ftp.gnu.org','anonymous','') puts ftp.list ftp.quit疾桓
源代码判断，当ftp库试图从服务器获取响应并且响应为空时，会引发此异常。 您应该将此命令包装在（或只是）并相应地处理错误。棠媳鳖
#!/bin/ruby require 'socket' buffer = "A" * 512 host = 'xx.xx.xx.xx' port = 21 s = TCPSocket.open(host, port) s.recv(1024) s.send("USER anonymousrn", 0) s.recv(1024) s.send("PASS anonymousrn", 0) s.recv(1024) s.send(buffer + "rn", 0) sleep 0.3 s.close
