I used to capture promiscous on sun boxen without any problem.
So it might be an issue with permissions of the /dev/ node for the
interface which I remember I had to change myself.
.
Can you capture as root?
If so which are the permissions on /dev/ifname?
What happens if you change permissions on /dev/ifname so that it is
writable by the user, can you capture promiscuous then?

Hi ,
Thanks for getting back to me....tcpdump does not capture either....i
have been reading up on this and here it is.
The laptop I use is not as secure as Sun server and the nic card can be
turned into promiscuous mode easily by software,
But on the Sun server I don't think the software can turn it into
promiscuous mode and thus the Nic card will not show the sniffer(i.e.
snoop,tcpdump,tethereal,tshark) traffic from Mac address other than its
own mac address for security reasons.
So I think now my question is:
Is there a command I can run which will put the nic card on the SUN
server(i.e. Solaris 10) into promiscuous mode?
Agree with my thinking?
Will

What about tcpdump, does it capture?
What happen if you run it as root, can you capture?
is /dev/ifname readable by the user you are trying to capture with?

interface to where the cable is, give it a dummy ip address,netmask and
broadcast address and bring it up. Issue is when I run Tshark I see no
packets.
