Re: [Tutor] 3 questions for my port scanner project
2. I got a while loop which does the port scan itself. How can I end it while its working ? using the break statement anywhere inside the loop will exit the loop. 3. For some reason the scan is too slow (2-3 seconds for a port). Is there a way to make it faster (other port scanner work allot faster... The ports which do not respond are the ones which take most of the time.You can use the timer object to fix the time for each port.For eg. if a port does not respond within .1 sec it can reasonably be expected to be closed.The exact implementation will depend upon your code.You can also use threads to ping more than one port simultaneously. And I loved your microsoft quote :). Cheers -- 1. The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners. 2.

Thank you very much for yuor help !! Now I only need to figure out how to make a progress bar and my trubles are over :) -- 1.

Re: [Tutor] 3 questions for my port scanner project
Use a canvas and redraw a rectangle slightly larger every time through the scanning loop. Thats think this is the easy part... The hard part is to make the bar move with the program (so every port it finishes the bar will slightly move, which depends on the total number of ports to scan...). But since you know the range of ports you can calculate the total number. If you keep a count of how many scanned you can work out the percentage scanned. You then draw a rectangle the same percentage of the total width. After each port scanned recalculate the percentage and redraw the rectangle. Where's the problem? :-) Alan G. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

How can I end it while its working ? previous message with code: *http://tinyurl.com/3lobo* **I'm not totally sure of this, but you might try adding another conditional to your while loop that can be toggled by a Scan and Stop button in your Tkinter app. global ok_to_scan ok_to_scan = 1 # or True while (start_port = end_port) and ok_to_scan: # ... do scan ... root.update() then bind a function to a Stop button which toggles 'ok_to_scan' to 0 (or False), also as previously suggested you should close the sockets that find an open port (sk.close()) inside your while loop.
