in the program below i want it to make it work the same way as TRACERT
command . but i am not able to make it work the same way . for which i need
your help thank you
here is the program
#!/usr/bin/python
import socket
import struct
import sys
# We want unbuffered stdout so we can provide live feedback for
# each TTL. You could also use the "-u" flag to Python.
class flushfile(file):
def __init__(self, f):
self.f = f
def write(self, x):
self.f.write(x)
self.f.flush()
sys.stdout = flushfile(sys.stdout)
def main(dest_name):
dest_addr = socket.gethostbyname(dest_name)
port = 33434
max_hops = 10
icmp = socket.getprotobyname('icmp')
udp = socket.getprotobyname('udp')
ttl = 1
while True:
recv_socket = socket.socket(socket.AF_INET, socket.SOCK_RAW, icmp)
send_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, udp)
send_socket.setsockopt(socket.SOL_IP, socket.IP_TTL, ttl)
# Build the GNU timeval struct (seconds, microseconds)
timeout = struct.pack("ll", 5, 0)
# Set the receive timeout so we behave more like regular traceroute
recv_socket.setsockopt(socket.SOL_SOCKET, socket.SO_RCVTIMEO, timeout)
recv_socket.bind(("", port))
sys.stdout.write(" %d " % ttl)
send_socket.sendto("", (dest_name, port))
curr_addr = None
curr_name = None
finished = False
tries = 3
while not finished and tries > 0:
try:
_, curr_addr = recv_socket.recvfrom(512)
finished = True
curr_addr = curr_addr[0]
try:
curr_name = socket.gethostbyaddr(curr_addr)[0]
except socket.error:
curr_name = curr_addr
except socket.error as (errno, errmsg):
tries = tries - 1
sys.stdout.write("* ")
send_socket.close()
recv_socket.close()
if not finished:
pass
if curr_addr is not None:
curr_host = "%s (%s)" % (curr_name, curr_addr)
else:
curr_host = ""
sys.stdout.write("%s\n" % (curr_host))
