tcpdump - IP trace betrween two nodes

[Edouard Soriano <e_soriano@dapsys.com>]

Hello people,

I would like to trace IP data between two nodes.

My LAN:

           SWITCH
            |  |
            |  |
      -------  ----------
      |                 |
      |                 |
   Node A              HUB
                       | |
                 ------- --------
                 |              |
                 |              |
              Node B          TcpDump


The settings of tcpdump on TcpDump node are

tcpdump -s -l 1024 -x 'net 192.168.1 and ip[2:2] >= 1'

NetBios traffic is traced but nothing between IP traffic
between Node B and Node A


Any idea about ?

Thanks
