windows - Invalid port in python sockets -

i getting error while trying send bare icmp message using following snippet:

windows says port invalid given ip range.

def send_ping(source_ip,target_ip,data_function=construct_icmp_echo):     fail = 0     skt_send = socket.socket(socket.af_inet,socket.sock_raw,socket.ipproto_icmp)     skt_recv = socket.socket(socket.af_inet,socket.sock_raw,socket.ipproto_icmp)     (src_binary,) = struct.unpack (">l",socket.inet_aton(source_ip))     (tgt_binary,) = struct.unpack (">l",socket.inet_aton(source_ip))      skt_send.setsockopt(socket.sol_ip, socket.ip_ttl, 16)     ipheader = struct.pack("bbhhhbbhll",0x54,0xdc,48,50,8,16,1,0,src_binary,tgt_binary)     cksum = icmpcksum(ipheader)     ipheader = ipheader = struct.pack("bbhhhbbhll",0x54,0xdc,48,50,8,16,1,cksum,src_binary,tgt_binary)     skt_send.sendto(data_function(),(target_ip,22433))     skt_recv.bind((target_ip,22433))     skt_recv.settimeout(5)     thetime = datetime.datetime.now()     try:          s = datetime.datetime.now()         while time.time - s < 60:             = skt_recv.recvfrom(1024)[0]             hdr_reply = a[20:]             icmp_type = a[20]             if icmp_type == 0 :                 print ("got ping")                 fl = true                 return target_ip             if fl: break     except socket.timeout e:         raise e     return 

here: skt.recv_bind((target_ip,22433)) ip address have fed b- , c-class ip addresses.

you trying send port 22433 before receiving socket has bound port. skt_send.sendto() call therefore trying send non-existent endpoint - @ time of call there's nothing listening on port 22433. try putting skt_recv.bind() call before it.

it helpful see traceback given interpreter, vague description of error have guess went wrong.
