When TCP/IP end system security is enabled, a security administrator or operator can use the following command to load a rules file:

NW TCPIP SECURITY + [“<filename>“]

where <filename> is the quoted name of a sequence data file that contains a set of Deny and Allow rules.

If no file is specified, the *SYSTEM/TCPIPSECURITY/RULES file (normally located on the pack where TCPIPSECURITY is SLed) is loaded.

Note that library initiation takes place asynchronously. An attempt is made to start the TCPIPSECURITY library immediately. No TCP/IP traffic will be allowed until the library is linked and a rules file is loaded. The following message is returned if the library is not linked:

TCP/IP End System Security Library Not Linked

If the command is unsuccessful, one of the following messages might be logged:

TCP/IP Security Linkage Failure. Link error = < # >.

TCP/IP Security Rule File Missing
