Step 8—Starting TCP/IP and TCP/IP Servers
Before any TCP/IP services are available on the iSeries system, TCP/IP processing
must 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 the
TCP/IP interfaces, and starts the TCP/IP server jobs. Only TCP/IP interfaces with
AUTOSTART *YES are started at STRTCP time. Allow a few moments for TCP/IP
to 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 jobs
related 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 and
QSYSOPR message queues. To check for the successful start of TCP/IP, enter either
of these commands:
DSPMSG QSYSOPR
DSPMSG QTCP
Figure 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 for
these job logs is QTCP. Use the Work with Spooled Files (WRKSPLF) command
and specify QTCP for the user (WRKSPLF QTCP) to find the logs.
Application Servers: The TCP/IP application server jobs run under subsystem
QSYSWRK. 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 automatic
start attribute for that server is equal to *YES. To change the autostart attribute for
an application, do either of the following:
v
Select option 2 from the TCP/IP Administration menu
v
Option 20 from the TCP/IP Configuration menu
