Scripts that show some examples on how to use the SOCKET module.
Do a FQDN search through a series of IPs.
import socket from netaddr import * import pprint #Creating a socket #URLs and port is defined along with the message we want to send. #url = 'www.google.com' port = 80 message = "GET / HTTP/1.1\r\n\r\n" for loop in [ 'www.google.com', 'www.yahoo.com', 'www' ]: sckt = socket.socket(socket.AF_INET, socket.SOCK_STREAM) try: #The FQN is being resolved and the IP is being printed remote_ip = socket.gethostbyname(loop) #print remote_ip print "Able to resolve to %s " % loop except socket.error, msg: #print "ERROR1: %s %s" % (socket.error, msg) print "Unable to resolve %s " % loop try: #We are connecting with the remote site by using the IP sckt.connect((remote_ip, port)) print "Able to connect to %s " % loop except socket.gaierror, msg: #print "ERROR2: %s %s" % (socket.error, msg) print "Cannot connect to %s " % remote_ip #You can send a reply regardless if the site is up or not. #This is not a good at all indicator for if a site is down or not. # try: # #We are sending data worth of 4096 kbs # sckt.sendall(message) # reply = sckt.recv(4096) # #print reply # print "Able to send reply" # except socket.error, msg: # #print "ERROR3: %s %s" % (socket.error, msg) # print "Error3" #We are closing our socket sckt.close()
Do a Reverse Lookup for hostnames
for loop in ['10.0.0.6', '10.0.0.60']: try: dns = socket.gethostbyaddr(loop) print dns except socket.error, msg: print "%s" % msg
