Socket sniffer python only sniff port 22

I am programming a sniffer in python with sockets and I am not sure why I am only sniffing on port 22. I am in a machine connected via ssh from ip 10.0.0.2 to 10.0.0.3 and when I sniff I only sniff ssh traffic I'm trying to do this to sniff traffic without port 22:

import socket
from struct import *

print 'Bienvenido'

s = socket.socket(socket.AF_INET,socket.SOCK_RAW,socket.IPPROTO_TCP)

while True:
    packet = s.recvfrom(65000)
    packet = packet[0]
    ip_header = packet[0:20]
    iph = unpack('!BBHHHBBH4s4s' , ip_header)

    ip_src = socket.inet_ntoa(iph[8])
    ip_dst = socket.inet_ntoa(iph[9])

    tcp_header = packet[20:40]
    tcp_h = unpack('!HHLLBBHHH',tcp_header)
    src_port = tcp_h[0]
    dst_port = tcp_h[1]
    if str(dst_port)!="22":
        print 'ip_src : ' + ip_src
        print 'ip dst : ' + ip_dst
        print 'src port: ' + str(src_port)
        print 'dst port: ' + str(dst_port)

      

        
        
        
      

    

But I dont sniff anything, if I go to if str(dst_port)!="22":

, I sniff traffic from 10.0.0.2 to 10.0.0.3. On the remote machine, I started tcpdump sniffing on port 80 connected to google via telnet on port 80, I also tried FTP traffic but no luck and I sniff in tcpdump but not on my sniffer. Anyone what could happen? Thank you in advance
