Issue/Introduction

Following installation of SO11270 and SO11269 a new parameter for  LPDSERV Parameters was introduced:

IPPPORT=XXXXXX

If this parameter is not specified, there may be problems concerning user exit ESFU011 and LPD printing.

However specifying this port poses a potential security issues as every active listening port in our enterprise must be approved because it could be used as an attack vector to compromise other systems.

Is there a solution to disable LPD/IPP interface.
