Mapping (listening) ports to services 1

[tpms2000]

I am completely new to this so apologies in advance if it's a dumb question.

I am writing an installation guide (for an IBM product on Windows) - part of which has the following -

Check that the following ports are free:
a) 80 (HTTP)
b) 383 and 636 (LDAP)
c) 9080 (Websphere)

If I run "netstat -a" I can see all listening ports
If I run "Start > Control Panel > Administrative Tools > Services" I can see services and their status

How can I see which service is using which port so if any of the above ports were already being used, I would know which service to stop?

Thanks in advance

I use the following and a cmd script to do something similar.

netstat -a -b -n
pause

It produces the results that you are looking for I believe. When you do it look for the svchost.exe entries, this will list the services that are in use. You may need to do internet lookups to match the dll files to the services.

But I am curious why you would close services, and I am even more curious as to why you do not distinguish between TCP and UDP, and I am finally curious why your application is not distinguishing port usage along the IANA model which XP (and other Windows products) conform to --

Install a good firewall and check the logs
They have inside every thing that you need

Which *.exe accessed which protocol, at which port, to what destination ip and to what destination port.

Also a sniffer will help you see what exaclty is being transfered

Good Luck

Firstly, many thanks for the responses.
Just to clarify - I am looking for a dynamic mapping of ports and services.
In response to "why am I closing a service" - IBM Websphere's HTTP server uses port 80 therefore when installing this on Windows Server 2000, the World Wide Web Publishing Service should be closed before installing the IBM stuff.
Finally - is there a common directory where can I find firewall logs on XP?

Some things for you to look at.
