APAR Error Description / Circumvention

-----------------------------------------------
When QAUDLVL/QAUDLVL2 is set to include *NETSCK, the SK audit
records for sub type A do not appear for Telnet connections.

CORRECTION FOR APAR MA44472 :
-----------------------------
The socket processing for the Telnet server happens outside the
scope of a job/process which precluded generating the SK audit
record.  The SK audit record job/process restriction is now
removed.  Other internal restrictions may still apply but after
applying this APAR there will be additional SK A and C audit
records created that specify a LIC task name instead of a
process name.

The Telnet server specific SK audit records will not be audited
by default when *NETSCK is configured.

Telnet client configuration and the number of clients connecting
to the Telnet server contribute to the rate of audit record
generation. Connections to the Telnet server could be quite high
and result in corresponding high rates of journal receivers
filling up.  System configuration and resources should be
considered before enabling SK auditing for the Telnet server.

Telnet clients configured to retry immediately without any delay
after error will generate audit records as fast as the Telnet
server can accept the incoming connections.
Some common cases where connections end in error after being
accepted include:
-The Telnet server is active but the QINTER subsystem is not
-QAUTOVRT rejects connections because there are no available
devices and it is not able to create new ones
-The certificate assigned to the Telnet server has expired, or
has been renewed and clients are still using the old certificate

This APAR provides the ability to enable and disable SK audit
records for sub type A for incoming Telnet connections.

To change the SK audit settings for Telnet with the Start
System Service
Tools (STRSST) command, follow these steps:
1. Open a character-based interface.
2. On the command line, type STRSST.
3. Type your service tools user name and password.
4. Select option 1 (Start a service tool).
5. Select option 4 (Display/Alter/Dump).
6. Select option 1 (Display/Alter storage).
7. Select option 2 (Licensed Internal Code (LIC) data).
8. Select option 14 (Advanced analysis).
9. Select option 1 (IPCONFIG).
10. Enter -h

This will show the help screen that describes the input
strings to change the SK auditing for Telnet setting
-skTelnetAudit.
