Step 8—Starting TCP/IP and TCP/IP ServersBefore any TCP/IP services are available on the iSeries system, TCP/IP processingmust be initialized and activated. To start TCP/IP, you have two options:1. Select option 3 from the TCP/IP Administration menu (GO TCPADM),2. Enter the Start TCP/IP (STRTCP) command.The STRTCP command initializes and activates TCP/IP processing, starts theTCP/IP interfaces, and starts the TCP/IP server jobs. Only TCP/IP interfaces withAUTOSTART *YES are started at STRTCP time. Allow a few moments for TCP/IPto start, and then check to see if the QTCPIP job has started.Option 20 of the TCP/IP Administration menu allows you to display the jobsrelated with TCP/IP. You can also use the following command:WRKACTJOB SBS(QSYSWRK) JOB(QT*)The job QTCPIP should be displayed.Messages indicating that TCP/IP has been started are sent to the QTCP andQSYSOPR message queues. To check for the successful start of TCP/IP, enter eitherof these commands:DSPMSG QSYSOPRDSPMSG QTCPFigure 17 contains a sample of the messages that are issued.If the QTCPIP job does not start, look for spooled job logs. Generally, the user forthese job logs is QTCP. Use the Work with Spooled Files (WRKSPLF) commandand specify QTCP for the user (WRKSPLF QTCP) to find the logs.Application Servers: The TCP/IP application server jobs run under subsystemQSYSWRK. Several types of TCP/IP server jobs run in the QSYSWRK subsystem.They are the server jobs for TELNET, POP, FTP, SMTP, LPD, BOOTP, TFTP,RouteD, REXEC, and SNMP.The STRTCP command starts the server jobs for an application if the automaticstart attribute for that server is equal to *YES. To change the autostart attribute foran application, do either of the following:v Select option 2 from the TCP/IP Administration menuv Option 20 from the TCP/IP Configuration menuSTRTCP issued by job 007138/DJONES/DSP02.QTCPIP job started.127.0.0.1 interface started.QTCPIP job starting 9.5.5.162 interface.127.0.0.2 interface started.SNMP Server starting.TELNET Server startingFTP Server startingSMTP Server startingPOP Server startingLPD Server starting9.5.5.162 interface started.STRTCP completed successfully.Figure 17.
