IBM i Exit Points for TCP/IP Application Management and Validation

Exit Point Interfaces for TCP/IP Application Exit Points

The exit point interfaces for TCP/IP application exit points are:

v TCP/IP application request validation exit point interface

v TCP/IP remote execution server command processing selection exit point

interface

Note: For a detailed description of the DHCP exit points and how to use them, see

System API Reference

TCP/IP Application Request Validation Exit Point Interface

Required Parameter Group:

1	Application identifier	Input	Binary(4)
2	Operation identifier	Input	Binary(4)
3	User profile	Input	Char(10)
4	Remote IP address	Input	Char(*)
5	Length of remote IP address	Input	Binary(4)
6	Operation-specific information	Input	Char(*)
7	Length of operation-specific	Input	Binary(4)
	information
8	Allow operation	Output	Binary(4)

Exit Point Name: QIBM_QTMF_CLIENT_REQ

Exit Point Name: QIBM_QTMF_SERVER_REQ

Exit Point Name: QIBM_QTMX_SERVER_REQ

Exit Point Name: QIBM_QTOD_SERVER_REQ

Exit Point Format Name: VLRQ0100

The TCP/IP request validation exit point enables additional control for restricting an operation. Any restrictions that are imposed by the exit program are in addition to any validation that is performed by the application program, such as normal server object security. When an exit program is added to the exit point, it is called by the TCP/IP application to validate the requested action specified by the operation identifier and other input parameters in the required parameter group. The exit program sets the output parameter, Allow operation, to indicate if the TCP/IP application is to perform the operation.

Note: All character data passed to the exit program is in the coded character set ID (CCSID) of the job, or if the job CCSID is 65535, the default CCSID of the job.

Required Parameter Group

Application identifier

INPUT; BINARY(4) Identifies the application program from which the request is being made. The valid values are as follows:

0FTP client program

1FTP server program

2REXEC server program
