Topic: port scan

[Crome]

If I use the portscan link in my server manager (SME 6.0.1-01 custom) I get the following output:

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on localhost (127.0.0.1):

3128/tcp   open        squid-http              

Nmap run completed -- 1 IP address (1 host up) scanned in 2 seconds

Can anybody tell me which interface this tool is scanning. Is it the internal or the external?

I would guess internal since localhost.  looking at a server (vs6) from the WAN, you usually get as standard:

Interesting ports on mail.yourdomain.org (203.45.16.312):
(The 1596 ports scanned but not shown below are in state: filtered)
Port       State       Service (RPC)                  
25/tcp     open        smtp                    
80/tcp     open        http                    
113/tcp    open        auth                    
443/tcp    open        https                  

Unless you open other things...

I hope so. I wouldn't really like netbios to be open to the entire world...
