Why Does Java Open Port 12345?

morganelan — Thu, 02 Feb 2006 06:50:04 GMT

Dear all Unix Gurus,

I have done running lsof on my production server to capture application that opens port 12345.The output looks like follow:
java 27222 apps11i 55u IPv4 0x4ef0d280 0t0 TCP myhost.domain.com:12345 (LISTEN)

My question is how to close this port with right procedure?Thanks in advance.

You either kill the process or you have the developer change the port to something else to your liking. Port 12345 is reserved for Italk: http://www.iana.org/assignments/port-numbers

Shalom,

I don't think java did it. I think your application programmer(s) did it.

First of all, Welcome back Harry after a long pause.

Hi Morganelan,

You can kill the java process which listens on this port. Check with others before doing so.
