TCP程式設計 埠掃瞄器與網遊客戶端

二、編寫網遊客戶端

開啟visual studio,選擇windows 窗體應用

窗體設計

**實現

using system;

using system.windows.forms;
using system.net;
using system.net.sockets;
namespace scan1
private int port;
private string address;
private bool[
] done = new bool[
65536];
private int start;
private int end;
private bool ok;
private void
button1_click
(object sender, eventargs e)
private void
scan1()
while
(!ok)}}
listbox1.items.
add(
"掃瞄結束！");
}else
} private void
scan()
catch }}}

**實現：

using system;

using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.threading.tasks;
using system.windows.forms;
using system.threading;
using system.net.sockets;
namespace scan2
private void
listbox1_selectedindexchanged
(object sender, eventargs e)
private void
label1_click
(object sender, eventargs e)
private void
start_port
(object sender, eventargs e)
catch
}//獲取結束埠
private void
end_port
(object sender, eventargs e)
catch
}//獲取ip位址
private void
get_ip
(object sender, eventargs e)
//ip檢驗
private bool judge_ip()
;int sum =0;
int j =0;
for(
int i =
0; i < n; i++)if
(j ==4||
(ip[i]
=='.'
&& ip[i +1]
=='.'))
sum = sum *10+
(ip[i]
-'0');
}if(j ==3)
}return true;
}return false;
} private void
scan()
);} catch
} private void
port_scan()
);"開始掃瞄……(該過程可能會等待一定時間！)");
for(
int i = startport; i <= endport; i++))
;}bool flag = true;
while
(flag)}if
(i == endport +1)
//執行緒暫停2000ms
system.threading.thread.
sleep
(2000);
} this.
invoke
((eventhandler)delegate
);"掃瞄結束！！！");
}else
}else
}//開始掃瞄
private void
button_click
(object sender, eventargs e)
//用單一程序測試埠掃瞄
private void
main_thread()
catch
}}private void
form1_load
(object sender, eventargs e)
private void
progressbar1_click
(object sender, eventargs e)
}}

TCP程式設計 埠掃瞄器與網遊客戶端

1 建立工程 選擇型別 設定介面 記錄當前掃瞄的埠號 private string address 記錄掃瞄的系統位址 private bool done new bool 65536 記錄埠的開放狀態 private int start 記錄掃瞄的起始埠 private int end 記錄掃瞄的...

TCP程式設計 埠掃瞄器

對於單執行緒的埠掃瞄可參考如下 using system using system.windows.forms using system.net using system.net.sockets namespace portscan 自定義變數 private int port 記錄當前掃瞄的埠號 ...

TCP埠掃瞄器

乙個基於python3的tcp埠掃瞄器 原理 就是和不同的埠進行tcp連線，能連線成功就表示此埠是開放的，不能連線成就表示此埠是關閉的。import socket import re import threading import time lock threading.lock threads l...
