The network table contains the networks and the Internet address associated withthe network. Socket applications use the getnetbyname() and getnetbyaddr()functions to access the information in the network table (Figure 61).The protocols and services tables that are shipped contain standard information.The network tables do not contain any information. The network IBM informationhas been added in Figure 61, as an example.For additional information about sockets, refer to Socket Programming(http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzab6/rzab6soxoverview.htm) in the Information Center. If you are using theSupplemental Manuals CD, then switch to the iSeries Information Center CD toaccess this information.Using X.25 PVC instead of SVCIn “Step 5—Configuring TCP/IP Remote System Information (X.25)” on page 16you were shown how to define the X.25 network address of each system that usesa switched virtual circuit (SVC).To replace the X.25 SVC with an X.25 permanent virtual circuit (PVC) connection,the example below is helpful. The following CL commands will look different:CRTLINX25, ADDTCPIFC, and ADDTCPRSI.Use the same X.25 line description, but replace the first of the four SVCs with aPVC.CRTLINX25 LIND(X25LINE) RSRCNAME(LIN051)LGLCHLE((001 *PVC) (002 *SVCBOTH)(003 *SVCBOTH) (004 *SVCBOTH))NETADR(40030003) CNNINIT(*LOCAL)TEXT('ITSO X.25 Network')Work with Network Table EntrySystem: SYSNAM03Type options, press Enter.1=Add 4=Remove 5=DisplayInternetOpt Network address_ _____________________________________ ________________ IBM 9.0.0.0BottomParameters for options 1 and 4 or command===> ______________________________________________________________________F3=Exit F4=Prompt F5=Refresh F6=Print list F9=Retrieve F12=CancelF17=Top F18=BottomFigure 61.
