[源码]K8 Cscan模块 C#扫描内网主机IP/机器名/Banner/网页标题源码

Cscan内置Delphi、VC、.NET例子,需要更多功能,请自行添加完善

                //return ip + "\t" + System.Net.Dns.GetHostByAddress(ip).HostName;

            }

        }

        private static string getURLbanner(string url)
        {

            url = "http://" + url;

            try
            {
                var req = (HttpWebRequest)WebRequest.CreateDefault(new Uri(url));
                req.Method = "HEAD";
                req.Timeout = 10000;
                var res = (HttpWebResponse)req.GetResponse();

                if (res.StatusCode == HttpStatusCode.OK || res.StatusCode == HttpStatusCode.Forbidden || res.StatusCode == HttpStatusCode.Redirect || res.StatusCode == HttpStatusCode.MovedPermanently)
                {
                    return res.Server;
                }

                //res.Close();

                return res.Server;
            }
            catch (WebException ex)
            {
                return "";
            }
        }

        private static string GetTitle(string html)
        {

            String regex = @"<title>.+</title>";

            String title = Regex.Match(html, regex).ToString();
            title = Regex.Replace(title, @"[\""]+", "");
            return title;

        }

        private static string getHtml(string url)
        {

            try
            {
                if (!url.ToLower().Contains("https://") && !url.ToLower().Contains("http://"))
                    url = "http://" + url;

                WebClient web = new WebClient();
                byte[] buffer = web.DownloadData(url);
                return Encoding.UTF8.GetString(buffer);

            }
            catch (Exception ex)
            {
                return ex.Message;
            }

        }

    }
}

编译成netscan.dll后,放置Cscan.exe同目录即可(netscan.dll优先级最高,无须删除其它插件)

ip.txt填上当前IP段或内网多个IP段，执行Cscan.exe。

Cscan20对应.net 2.0编译,所以编译的DLL也要对应版本

实战使用哪个版本，由目标系统已安装.net版本来决定。

结果如图
