Just wanted to see how few lines I could do it in. If you don’t include the ‘includes’ or the ‘except:pass’, it’s really only two lines.
#!/usr/bin/python import sys from socket import * for port in range(int(sys.argv.split('-')), int(sys.argv.split('-'))+1): try:socket(AF_INET, SOCK_STREAM).connect((sys.argv, port)); print "Able to connect to port:", port except: pass
Usage: <filename> <host> <ports>
So for example if you saved this as pyscanner.py, and chmod +x it, you could do:
./pyscanner.py localhost 1-1024
to scan the priviledged ports on your local box.
If it isn’t obvious from the code, it does not support IPv6 addresses and determines of a port is connectable via a standard TCP connect().
