I need to resolve this; does anyone have any pointers for me as to where
I can look or what I can try?

tcpdump shows differences between smbclient -L and Nessus against an NT
host. smbclient returns valid results, Nessus does not :(

Nessus doesn't appear to be pulling the hostname to provide in the SMB
query. How can I modify this behevior?

Thanks!

Hello,

I am trying to scan an NT host on tcp/139. I believe I am having
problems with name resolution. It is preventing me from getting results
I know are present but unable to get out of nessus. I'm on 2.2.4 with
latest plugins (direct feed).


I know the host can have it's shares browsed and can verify as much with
smblient. The applicable info seems to be:
Session request, to 1.1.1.210<20> from SCANNER1<00>
Negative session response, Called name not present
Session request, to 1<20> from SCANNER1<00>
Negative session response, Called name not present
Session request, to *SMBSERVER<20> from SCANNER1<00>
Positive session response


When I tcpdump the Nessus scan I get a lot of these:
Session request, to 1.1.1.210<20> from                <20>
Negative session response, Called name not present

This happens quite a few times without changing to destination name.

/etc/hosts and /etc/resolv.conf look fine (it runs fine from smbclient
after all). 

Where can I look next? 

Thank You.
