Hi, I try to change the code found, for it then run a scan ip ranks while checking the predefined ports in the code is open, if open port on an IP address during the scan, save to a file IP txt
Code
#!/usr/bin/env python
import socket
import subprocess
import sys
from datetime import datetime
# Clear the screen
subprocess.call('cls', shell=True)
# Ask for input
remoteServer = raw_input("Enter a remote host to scan: ")
remoteServerIP = socket.gethostbyname(remoteServer)
# Print a nice banner with information on which host we are about to scan
print "-" * 60
print "Please wait, scanning remote host", remoteServerIP
print "-" * 60
# Check what time the scan started
t1 = datetime.now()
# Using the range function to specify ports (here it will scans all ports between 1 and 1024)
# We also put in some error handling for catching errors
try:
for port in range(1,1000):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex((remoteServerIP, port))
if result == 0:
print "Port {}: Open".format(port)
sock.close()
except KeyboardInterrupt:
print "You pressed Ctrl+C"
sys.exit()
except socket.gaierror:
print 'Hostname could not be resolved. Exiting'
sys.exit()
except socket.error:
print "Couldn't connect to server"
sys.exit()
# Check the time again
t2 = datetime.now()
# Calculate total time; subtract start time from end time
total = t2 -t1
# Print the total time on screen
print '\n'
print '-' * 60
print "Total scan time: ", total
print '-' * 60
