Nessus is Not Scanning

    Hi all,



I've installed Nessus 3.0.3 build W327 beta version to my windows pc
but it is not performing scanning. Is it restricted to only localhost?
Is there anyone who can help me to find what the problem is?



Here are some information about it:


    
  
  • Nessus scanner service is running
    
  
    • 
  
  • I can scan my own computer (scans localhost) but,
    
  
    • 
  
  • I cannot scan another IP
    
  
    • 
  
  • When I run ethereal to look what's going on, I cannot see any traffic also.
    • 


Thanks

    I agree with Andre. I can't see the need for this 
option.

 


The link-address field in the relay-forw message is 
addressing information for the server to use in determine where the client is 
(for address assignment/prefix-delegation purposes). There is ***NO*** 
requirement that this address be an address that the relay-agent has 
configured.


 


The address of relay agent is in either the peer-address 
field (if this isn't the first hop relay) or in the SOURCE address of the 
relay-forw packet. Thus, unlike in DHCPv4 where the giaddr field is overloaded 
to mean two things, that is NOT the case for DHCPv6.


 


Unless you can come up with a reason why the link-address 
field isn't sufficient, I can't see supporting this work.

Hello,Kostur


    Thank you!


    


    Yes, it is a counterpart of DHCPv4 
link-selection sub-option, so we used a similiar option name. And we 
missed it in the draft, sorry.


   


    I obtain the requirement from NetLMM 
Base protocol, the draft is still in progress.

  When a mobile mode connects to the NetLMM 
infrastructure, it first needs to configure an address,i.e.NetLMM Address. This 
address is the invariant IP address on the MN inside the NetLMM domain. And 
the IPv6 link prefix of the NetLMM address comes from LMA, not 
MAG. 


 


   From my understand, link-address field 
holds the address of the relay agent. And so, we think that only using 
link-address can not satisfy the above requirement.

I don't understand the requirement for this draft.  From 
  what I understand, this is to allow the Relay Agent to select the link/prefix 
  from which to make an allocation.  This is basically a v6 version of the 
  Link Selection Suboption for dhcpv4.  However, from my reading of RFC 
  3315, this functionality is already supported in the link-address field of the 
  Relay-forward message:

  
      link-address   A 
  global or site-local address that will be used by 
           ;          
  the server to identify the link on which the client 
           ;          
  is located. 

  
What behaviours does this draft cover that the link-address 
  field doesn't address?
