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. 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).

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,
