Steps for administering SERVAUTH class profiles to enable RRSF to use TCP/IP node connections

Perform the following steps to define the required SERVAUTH profiles on each node to be enabled to use TCP/IP connections:

Determine whether access to the TCP/IP stack is protected. If it is, the following resource is protected in the SERVAUTH class:
```
EZB.STACKACCESS.sysname.tcpname
```
______________________________________________________________________
If the TCP/IP stack is not protected, skip this step.
If it is protected, add the user ID of the RACF® subsystem to the access list for the TCP/IP stack:
Example:
```
PERMIT EZB.STACKACCESS.NODE1.TCPIP CLASS(SERVAUTH) ID(RACFSUB) ACCESS(READ)
```
Note: If the TCP/IP stack is protected, do not skip this step even when the user ID of RACF subsystem has the TRUSTED or PRIVILEGED attribute on your system.
______________________________________________________________________
If a SAF name is assigned to the RRSF listener port in the TCP/IP profile, protect the listener port with a profile that protects the following resource:
```
EZB.PORTACCESS.sysname.stack-name.SAF-name
```
Examples:
```
RDEFINE SERVAUTH EZB.PORTACCESS.NODE1.TCPIP.RRSF
-or-
RDEFINE SERVAUTH EZB.PORTACCESS.*.*.RRSF
```
Specify the SAF name provided by the programmer in Before you begin.

______________________________________________________________________
Add the user ID of the RACF subsystem to the access list for the RRSF listener port:
Example:
```
PERMIT EZB.PORTACCESS.NODE1.TCPIP.RRSF CLASS(SERVAUTH) ID(RACFSUB) ACCESS(READ)
```
Note: Do not skip this step even when the user ID of RACF subsystem has the TRUSTED or PRIVILEGED attribute on your system.
______________________________________________________________________
Activate your SERVAUTH profile changes, as follows.
- If the SERVAUTH class is not already active, activate and RACLIST it.
  Example:
```
SETROPTS CLASSACT(SERVAUTH) RACLIST(SERVAUTH)
```
- If the SERVAUTH class is already active and RACLISTed, refresh it.
  Example:
```
SETROPTS RACLIST(SERVAUTH) REFRESH
```

When you are finished, you have administered the SERVAUTH class profiles required to enable each RRSF node to use TCP/IP node connections.
