Issue/Introduction

ACF2 reports are showing logon attempts by invalid userids using TPX as the source.

Example ACF2 LOGINS:

14:44:51      08.086 03/26 15.25 name name P-TPX termid * 4 system       
              08.086 03/26 15.27 name name P-TPX termid * 4 system                           

Is there a way within TPX to trace the origin of the logon attempt?

Environment

Release: 5.4
Component: TPX for Z/OS

Resolution

Use the Post-security call point of the TPXUSNSF Signon/Signoff exit to write a message containing the USERID and Terminal-ID to the TPX LOG, by using the LOGMSG macro.

 

• It would capture the USERID and TERMID.
• If IP address is needed, there is a variable (IPADDR) which contains that value. Code a TPXVGET macro for this.
