Hello Guy
Thank you for the quick reply. Transmissions from y are not to ip address
'X'. I have also confirmed that my Nic card supports promiscuous mode.
Is there any alternative so that I could capture all transmissions from
'X', including those not towards on which ethereal is running.(Effectively
an alternative for the switched-network or 10/100Mb hub problem)?
Warm Regards
Praveen.P

Are the transmissions from "y" being sent to the IP address "X"? I.e.,
are they being sent to the machine on which Ethereal is running?
If not, this may be a switched-network or 10/100Mb hub problem, which
prevents a machine on one port of a switch/switching hub or on one port
of a 10/100Mb dual-speed hub from seeing all the traffic on the network,
even if the machine's network interface is running in promiscuous mode:
