Dear Experts,

Today my manager asked me to check which all ports are opened & which all are closed.  Ports which are opened is been used by what. He wants the list i.e. ports- using application name . Do i need to check in each & every server or is it sufficient if i check in Domain server only or if i check in any one of the client computers.
I did run the command netstat -an in one of the client computer. I have attached the image of that. What is this Foreign address (*:*) & [::]:0 . Some local address it shows 0.0.0.0:135 & some other shows 127.0.0.1 . or is there any free tool which can give me all the details.
Note:- I am new to this server world. thats why asking such type of questions
Help Needed urgently.

Regards,

JCT

Use this application called nmap. It's been around for ages and will scan all the ports of a host and let you know what's open and what's listening. If you do not know common port numbers that a simple google find and depending on the amount of host you have in your network, you should be able to make your manager a happy person in a short amounf of time.

I've also attached a PDF of common ports and their protocols.

no, you can run it from a client and scan different hosts. What's not downloading?
