python編寫簡單的ip掃描工具

python最大的特點就是各種強大的模塊實現自己想要的功能。這裡介紹一個強大的工具––nmap。

windows環境下要先安裝nmap，地址
https://nmap.org/download.html，安裝 nmap-7.80-setup.exe，下面會用到。然後pip install nmap安裝python模塊。利用tkinter實現圖形化界面。功能實現程序：

<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 = 
"輸入掃描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, 
"請輸入正確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該網段無設備在線!\r\n"
%(ip))
        
else
:
            
for
 result 
in
 ping_scan[
'scan'
].keys():
                infotext.insert(tk.END,
"%s  設備在線!\r\n"
%(result))

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

topwin.mainloop()

注意：nmap.PortScanner(nmap_search_path=('nmap',r'C:\Program Files\Nmap\nmap.exe'))一定要按照自己安裝的路徑添加，否則報錯。

軟件實現效果如下圖所示：
