But for some reason it keeps working after its job is done in my app...
Here is the class:
(the app itself got some Entrys to get the input and a Button to start
the go() and stop() functions)
class scan(threading.Thread):
def _init_(self):
threading.thread._init_(self)
def scanner(self):
self.open_counter=0
self.flag='scan'
try:
host=host_e.get()
start_port=int(start_port_e.get())
end_port=int(end_port_e.get())
except ValueError:
tkMessageBox.showerror("Bad input","You must enter a vaild
host IP and port numbers.")
pass
else:
start.config(text="Stop",command=stop)
root.update()
result.insert(END,"Scanning "+str(host)+"...\n\n")
root.update()
while start_port<=end_port and self.flag=='scan':
self.sk=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sk.settimeout(0.01)
try:
self.sk.connect((host,start_port))
except:
pass
else:
result.insert(END,str(start_port)+"\n")
root.update()
self.open_counter=self.open_counter+1
self.sk.close()
start_port=start_port+1
if self.flag=='scan':
result.insert(END,"\nDone !!\nFound
"+str(self.open_counter)+" opened ports")
root.update()
start.config(text="Scan",command=go)
root.update()
elif self.flag=='stop':
result.insert(END,"\n Scan stopped.")
start.config(text="Scan",command=go)
root.update()
app=scan()
Here is the go() function, which starts the thread:
def go():
app.start()
app.scanner()
And here is the stop() function that should end the thread and the
scan (and for some reason it ends only the scan loop):
def stop():
app.flag='stop'
You got any Idea whats wrong here ??
Thanks allot.
