howto on windows 2012 r2 server find that an interval port is blocked and from who

Question

Hi i have an oracle application server on w2012 r2 server ..windows firewall is down and i don't know how to do to recognize that an interval port
<ORBPorts value="17000-17040"/> is blocked ...
the error on as oracle is:
IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: 10.10.15.31; port: 17002
oracle wants to know if that interval port is blocked or not...
if i run netstat -a-n-o i don't see 17002 ...
the directory
Y:\Windows\System32\LogFiles\Firewall is empty...
best regards and tkx for all that answers me

Answer 1

Hi,

Can you enable the FW logging follow the steps over here, jj717291(v=ws.11).

If you do not see the port running or service is down not sure how the port will be listed in Netstat. Can you try a telnet from another server on that port - Telnet 10.x.x.x. -port 17002.

Also check if any Antivirus is blocking it?

Hope this helps.

Hi tkx for you time and help..
the only antivirus was uninstalled
if i run from the server machine
C:\Users\Administrator>telnet 10.10.15.31 17002
Connecting To 10.10.15.31...Could not open connection to the host, on port 17002
: Connect failed

C:\Users\Administrator>

It functions only on 17001 port and the error on oracle application is corba error on 17002 port...
the orbs port is set by 17000-17040..but none port is enable except 17001...
How to enable the entire range?

if i run netstat -a-n-o i don't see 17002 ...

This command (in an admin command prompt) should show you the process id of the app that is listening on any 1700x port.

netstat -aon | findstr -i listen | findstr 1700  

If you don't have a process listening on port 17002, then there is nothing to block. The issue would then be that you have not configured the application on the server to listen on that port.
