localhost and ports

[naveen yadav]

hi ranchers ,

what is the range of port numbers can i assign to localhost apart from 8080 ?

suppose i want to install mysql server, glassfish server and oracle server. what about their port numbers do i have to assign different port number for each server OR can i use 8080 for all three server but in that case i can use only one sever application ?

In theory, all ports from 1 to 65535 can be used. There are some limitations though. For ports from 1 to 1024 you usually need administrative rights; under Linux you need to be root. Furthermore, several ports are already used by the system, like 137 for Windows sharing.

In your case though, MySQL can run on its default port 3306, Oracle on its default 1521 and Glassfish on 8080 without a problem.

what if i want to install apache tomcat after glassfish already at 8080 ? Do i have to assign different port ?

one more que:
how can one know which ports are been used by the system itself ?

[Rob Spoor]

Yes, you will need to run Tomcat on another port if Glassfish is already using port 8080.

As for the ports, use the netstat command. You'll need to use the -a flag to see the listening connections. Alternatively, you can use CurrPorts.

hi bob ,

whe i type netstat -a on command prompt (window xp)

it says : it is not recognized as internal or external command. what is problem here ?

[Rob Spoor]

No idea, every machine I have worked with has netstat. Try CurrPorts instead.

I think netstat.exe needs to be available in \WINDOWS\system32

Yes it is available there. But when i execute it flashes for a second or two and then closed automatically.

How can i see its output ?

Then go with Rob. Try CurrPorts instead.
