网络扫描应用程序 [英] Network scan application

问题描述

我们的网络中有大约400台个人电脑，按部门划分。每个部门都有自己的子网，例如：dept1有ip系列192.168.20.X，dept2有192.168.11.X.



我的问题是怎么可能我用VB .net应用程序获取ipaddress，主机名和mac地址并将其存储在数据库中。



希望我足够清楚。



谢谢。



我的尝试：



我尝试过使用：

< pre>对于i =  1     254  
 尝试 
 hostname =   
 ipaddr = < span class =code-string>  192.168.12。& i.ToString 
 hostname =（System.Net.Dns.GetHostEntry（  192.168.12。& i.ToString）.HostName.ToString）
 timestamp = DateAndTime.Now.ToString 
 如果 hostname<>   然后 
 < span class =code-keyword>如果 con.State = ConnectionState.Closed 那么 
 con.Open（）
 < span class =code-keyword>结束 如果 
 sql =  插入ipstats值（？，？，？） 
 cmd = 新 SqlCeCommand（sql ，con）
 cmd.Parameters.AddWithValue（  hostname，hostname）
 cmd.Parameters.AddWithValue（  ipddr，ipaddr）
 cmd.Parameters.AddWithValue （  t imestamp，timestamp）
 retvals = cmd.ExecuteNonQuery（）
 结束 如果 
  Catch  ex  As 例外
 结束 尝试 
 下一步 

但扫描整个网络需要大约一个小时才能完成网络中的所有机器。



我也可以不知道如何获取mac地址。

使用以下方式快速搜索Google： c＃本地网络发现 - Google搜索 [ ^ ]



发现这个： C＃ - SubnetScanner - 扫描你的（本地）网络 - YouTube [ ^ ]它有一个支持页面&源码下载链接： C＃子网扫描仪 - KIJUKA [ ^ ]



我知道这是C＃，但不应该是太难转换为VB。将压缩的项目文件上传到此处：代码转换器 [ ^ ]它将为您完成大部分工作...

Hi,
We have around 400 PC's in our network which is segregated by department wise. Each department has its own subnet for example : dept1 has the ip series 192.168.20.X and dept2 has 192.168.11.X.

My question is that how could i get the ipaddress, hostname and mac address with a VB .net application and store it in the database.

Hope i am clear enough.

Thank you.

What I have tried:

I have tried using:

<pre>For i = 1 To 254
            Try
                hostname = ""
                ipaddr = "192.168.12." & i.ToString
                hostname = (System.Net.Dns.GetHostEntry("192.168.12." & i.ToString).HostName.ToString)
                timestamp = DateAndTime.Now.ToString
                If hostname <> "" Then
                    If con.State = ConnectionState.Closed Then
                        con.Open()
                    End If
                    sql = "insert into ipstats values(?,?,?)"
                    cmd = New SqlCeCommand(sql, con)
                    cmd.Parameters.AddWithValue("hostname", hostname)
                    cmd.Parameters.AddWithValue("ipddr", ipaddr)
                    cmd.Parameters.AddWithValue("timestamp", timestamp)
                    retvals = cmd.ExecuteNonQuery()
                End If
            Catch ex As Exception
            End Try
        Next

But it take around an hour to scan whole network and it does not get all the machine in the network.

And also i could not figure out how to get mac address.

解决方案

A quick Google Search using: c# local network discovery - Google Search[^]

Found this: C# - SubnetScanner - Scan your (local) Network - YouTube[^] which has a support page & source download link: C# Subnet Scanner - KIJUKA[^]

I know that this is C#, but should not be too difficult to convert to VB. Upload the zipped project file to here: Code Converter[^] and it will do most of the work for you...

UPDATE: Actually, this is what you are looking for courtesy of OriginalGriff[^] : Retrieving IP and MAC addresses for a LAN[^]
