Issue/Introduction

The NetMaster Activity Log shows masses of these messages:

 

IPCM2002 TELNET CONNECTION STARTED FROM #.#.#.#..4925 AS TSTCP007 TO TEST1 LOGICAL DEVICE 0006

IPCM2003 TELNET CONNECTION ENDED FROM #.#.#.# AS TSTCP006 TO TEST4BYTES IN 550

OUT 32665 DURATION 0 DAYS 00.06
 

Environment

OS:  z/OS.

Cause

The NetMaster for TCP/IP Using tech docs section explains: 

 
Telnet Activity in the Log
 
The Telnet connections can be logged as they are started and ended.
 
Note:  Logging of Telnet activity is specified in the IPEVENT parameter group.
 
Example: Telnet Messages
 
These examples show the Telnet connection start and end messages:
 

IPCM2002 TELNET CONNECTION STARTED FROM #.#.#.#.4925 AS TSTCP007 TO TEST1 LOGICAL DEVICE 0006

IPCM2003 TELNET CONNECTION ENDED FROM #.#.#.# AS TSTCP006 TO TEST4, BYTES IN 550 OUT 32665 DURATION 0 DAYS 00.06.35

 

A logged connection start message contains the following information:
 
  • Time that the connection started
  • Port number, LU, and device number used
 
A logged connection end message contains the following information:
 
  • Time that the connection ended
  • IP address and LU name of the device where the connection ended
  • Application to which the session was connected
  • Number of bytes in and out
  • Duration of the connection 

Resolution

As noted, whether or not the messages are written to the log is controlled by /PARMS IPEVENT.

Change this section:


Telnet Event Processing:              Telnet Event ReceiverRunning

  Log Telnet Events? ......... YES   (to Activity Log)
  Save Telnet Events? ........ YES   (in Event History Dataset IPLOG)


to this:


Telnet Event Processing:              Telnet Event ReceiverRunning

  Log Telnet Events? ......... NO    (to Activity Log)
  Save Telnet Events? ........ YES   (in Event History Dataset IPLOG)


PF6 to action the parameter groupwhich will immediately implement the changes.

PF4 to save changes.

PF3 to exit the parameter group.
