Creating Python Pinger - Sockets -

ok, changed try , ask more specific question.

i have 2 methods. dooneping creation use sendoneping, written me in aid understand sockets better.

i trying understand if creating socket correctly within dooneping, believe am, not sure if missing specific or better.

thanks

def sendoneping(mysocket, destaddr, id):     # header type (8), code (8), checksum (16), id (16), sequence (16)      mychecksum = 0     # make dummy header 0 checksum     # struct -- interpret strings packed binary data     header = struct.pack("bbhhh", icmp_echo_request, 0, mychecksum, id, 1)     data = struct.pack("d", time.time())     # calculate checksum on data , dummy header.     mychecksum = checksum(header + data)      # right checksum, , put in header     if sys.platform == 'darwin':         # convert 16-bit integers host network  byte order         mychecksum = htons(mychecksum) & 0xffff     else:         mychecksum = htons(mychecksum)      header = struct.pack("bbhhh", icmp_echo_request, 0, mychecksum, id, 1)     packet = header + data      mysocket.sendto(packet, (destaddr, 1))  # af_inet address must tuple, not str   # both lists , tuples consist of number of objects # can referenced position number within object.  def dooneping(destaddr, timeout):     icmp = getprotobyname("icmp")     # sock_raw more details:   http://sock-raw.org/papers/sock_raw      # fill in start      mysocket = socket.socket(socket.af_inet, socket.sock_stream)      #fill in end       myid = os.getpid() & 0xffff  # return current process     sendoneping(mysocket, destaddr, myid)     delay = receiveoneping(mysocket, myid, timeout, destaddr)      mysocket.close()     return delay 

consider using scapy instead ping. can scapy running:

pip install scapy 

using able ping more easily
