trace route script
-
Simple trace route script fails in Pythonista, but works well in Python 2.7.5.
import socket
def main(dest_name):
dest_addr = socket.gethostbyname(dest_name)
port = 33434
max_hops = 30
icmp = socket.getprotobyname('icmp')
udp = socket.getprotobyname('udp')
ttl = 1
while True:
# error [Errno 1] Operation not permitted
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)
recv_socket.bind(("", port))
send_socket.sendto("", (dest_name, port))
curr_addr = None
curr_name = None
try: -
can you correctly format the script?

import socket def main(dest_name): dest_addr = socket.gethostbyname(dest_name) port = 33434 max_hops = 30 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) recv_socket.bind(("", port)) send_socket.sendto("", (dest_name, port)) curr_addr = None curr_name = None try: _, curr_addr = recv_socket.recvfrom(512) curr_addr = curr_addr[0] try: curr_name = socket.gethostbyaddr(curr_addr)[0] except socket.error: curr_name = curr_addr except socket.error: pass finally: send_socket.close() recv_socket.close() if curr_addr is not None: curr_host = "%s (%s)" % (curr_name, curr_addr) else: curr_host = "*" print "%d\t%s" % (ttl, curr_host) ttl += 1 if curr_addr == dest_addr or ttl >= max_hops: break if __name__ == "__main__": main('google.com')

good :-)

it gives an error in line 11: operation not permitted

Yes, I have tried everything I can think of to get he the code running in Pythonista, but with no luck. I was hoping that you could point me in a direction to solve the problem, as the code works in Python 2.7.5

will try Pipista, thanks.

it's for apple sandboxing
