Hi!

Well, when you are running an application (for
instance Apache), you can bind this app. to a port
and/or an address. In your case, the IP address
"0.0.0.0" means all addresses, i.e. if you have 2
NIC, your app. will be replying to requests coming
on the 2 NICs. 

Yes, when in the local address column, it means
all the IPs and interfaces. However, what does 
0.0.0.0:0 mean in the Foreign Addr column. If it
means all remote addresses using any of their
source ports, then what does *:* mean in the
Foreign address column? What I mean to ask is that
as you can see in my mail below, the foreign address
column either contains 0.0.0.0:0 or *:*, what does
this mean?



If you had "10.0.0.1" instead of
0.0.0.0, then just requests to 10.0.0.1 will be
treated!

For the ports, well just see in "
C:\WINDOWS\system32\drivers\etc\services " !!

To see the match with the applications, just
download fport (I think it should be that), or
tcpview (I am sure of this one, better for me than
the former).

Yes it helped me figure out the applications running
on these ports.

Thanks for your help.

Objet�: What does this mean?

Hello all,

I have a simple question and I hope to get an answer
from the experts on this list.

I have a PC running Windows 2000 Prof, and when I do
a netstat -an, I get the following:

Active Connections:
Proto  Local Addr    Foreign Addr     State 
============================================

TCP    0.0.0.0:135   0.0.0.0:0        LISTENING

TCP    0.0.0.0:445   0.0.0.0:0        LISTENING

TCP    0.0.0.0:1026  0.0.0.0:0        LISTENING

TCP    0.0.0.0:1027  0.0.0.0:0        LISTENING

UDP    0.0.0.0:135            *:*                   

UDP    0.0.0.0:445            *:*                   

UDP    0.0.0.0:1025           *:*                   

UDP    0.0.0.0:38037          *:*                   

UDP    172.20.4.76:500        *:*                   


I get this output even when I am running no network 
application on the machine.

Of course, this all seems quite suspicious. 

Can somebody please help me figure out what is going
on? At least find the respective applications
listening
on various ports.??

Thanks and best regards,
