python编写简单的ip扫描工具

python最大的特点就是各种强大的模块实现自己想要的功能。这里介绍一个强大的工具––nmap。

windows环境下要先安装nmap，地址
https://nmap.org/download.html，安装 nmap-7.80-setup.exe，下面会用到。然后pip install nmap安装python模块。利用tkinter实现图形化界面。功能实现程序：

<code>
import
 tkinter 
as
 tk
import
 nmap
topwin = tk.Tk()
 
topwin.title(
"ipScanV1.0"
)
 
topwin.geometry(
"400x200+20+20"
)
 
topwin.attributes(
"-alpha"
, 
1
)
 
topwin[
"bg"
] = 
"snow"
 
topwin.resizable(
False
,
False
)

 
infotext = tk.Text(topwin,bg = 
"Turquoise"
)
 
scrobar = tk.Scrollbar(infotext)
scrobar.pack(side=
"right"
, fill=
"y"
)
scrobar.config(command=infotext.yview)
 
infotext.config(yscrollcommand=scrobar.set)
infotext.tag_configure(
'color'
, foreground=
'Yellow'
,background  = 
"RoyalBlue"
)
infotext.place(x=
4
,y=
40
,width = 
400
,height = 
160
)

ipscanset = tk.Label(topwin,text = 
"输入扫描IP段："
).place(x=
10
,y=
10
)
iptext = tk.Entry(topwin)
iptext.place(x=
100
,y=
10
,width = 
140
,height = 
24
,anchor = 
"nw"
)

def
 
ipscan
()
:

    ipyn = nmap.PortScanner(nmap_search_path=(
'nmap'
,
r'C:\Program Files\Nmap\nmap.exe'
))
    ip = iptext.get()
     
    
if
 len(ip) == 
0
:
        infotext.insert(tk.END, 
"请输入正确IP或IP段！\n"
)
        infotext.insert(tk.END, 
"...............................\n"
)
    
else
:
        ping_scan = ipyn.scan(hosts=ip,arguments=
"-sn"
)
        infotext.insert(tk.END, 
"...............................\n"
)
        
if
 len(ping_scan[
'scan'
]) == 
0
:
            infotext.insert(tk.END, 
"%s该网段无设备在线!\r\n"
%(ip))
        
else
:
            
for
 result 
in
 ping_scan[
'scan'
].keys():
                infotext.insert(tk.END,
"%s  设备在线!\r\n"
%(result))

scanbtn = tk.Button(topwin,text = 
"扫描"
,command = ipscan).place(x=
250
,y=
10
,width = 
50
,height = 
24
)

topwin.mainloop()

/<code>

注意：nmap.PortScanner(nmap_search_path=('nmap',r'C:\Program Files\Nmap\nmap.exe'))一定要按照自己安装的路径添加，否则报错。

软件实现效果如下图所示：
