Issue/Introduction

What ports do we need to open if UUJMA is behind a firewall?

 

Environment

Release:
Component: UUJMA

Resolution

UUJMA listens on the port configured in /etc/services for the caicci service.

The default port is 1721.

The outgoing port number by default is random by the operating system. There is a CCI configuration variable that you can use to specify a starting port number, then you will need to open a range of numbers. What the cci variable allows you to do is specify the beginning port number to use prior to making a cci connection.

The variable name is CAI_CCI_PORT1 it configures ccirmtd so that it will bind to specified port prior to connect calls Valid values for this variable is CAI_CCI_PORT1=n, where 250 < n < 65000.

To set this variable create an executable file $CAIGLBL0000/cci/scritps/envsetlocal that contains

  CAI_CCI_PORT1=n   export CAI_CCI_PORT1 

Note: n should be a number that is greater then 250 and less the 65000.

Setting this up will configure cci when making outgoing calls to start at this port number and if that is not available it will increment the value by one and try the next port number.

Without this setting the outgoing port number is random and set by the operating system.

If you are connecting UUJMA to an Event Console machine and two managers then a range of 5 ports should be enough to open.
