1. Configuring Ethernet
   Power on your AS/400
   Signon as QSECOFR on a 5250 workstation
   Enter command wrkhdwrsc *cmn to find out what Ethernet adapter is installed and the resource name assigned to it
   Work with Communication Resources
   Type options, press Enter.
   5=Work with configuration descriptions 7=Display resource detail
   Opt Resource Type Status Text
   CMB01 675A Operational Combined function IOP
   LIN01 2720 Operational Communication Adapter

   Figure 1 - Work with Communication Resources

Enter the following command to create an Ethernet line
crtlineth lind(ETHLINE) rsrcname(CMN02) linespeed(100M)
Check the Ethernet cable. One side should be connected to the AS/400, the other side should be connected to the Ethernet hub.
Enter the following command to vary on the line
vrycfg cfgobj(ETHLINE) cfgtype(lin) status(on)
To check the line status enter command
wrkcfgsts cfgtype(*lin) cfgd(ETHLINE)
Note that the line will display the VARIED ON status until TCP/IP is started.

2. Configuring TCP/IP
   Enter command cfgtcp to receive the following menu
   Configure TCP/IP
   Select one of the following:

3. Work with TCP/IP interfaces

4. Work with TCP/IP routes

5. Change TCP/IP attributes

6. Work with TCP/IP port restrictions

7. Work with TCP/IP remote system information

8. Work with TCP/IP host table entries

9. Merge TCP/IP host table

10. Change TCP/IP domain information

11. Configure TCP/IP applications

12. Configure related tables

13. Configure point-to-point TCP/IP

Figure 3 - Work with TCP/IP Interfaces

Type 1 and press Enter to define your TCP/IP interface (substitute our sample values with your; see your checklist):
Add TCP/IP Interface (ADDTCPIFC)
Type choices, press Enter.

  X.25 DDN interface . . . . . . . *NO *YES, *NO
  TRLAN bit sequencing . . . . . . *MSB *MSB, *LSB
  Figure 4 - Add TCP/IP Interface

As an alternative, you may define the IP address of your AS/400 by entering the following command
addtcpifc intnetadr('192.168.0.2') lind(ethline)
subnetmask('255.255.255.0')

To start this TCP/IP interface, select it with 9=Start from the screen in Figure 3,
or just enter command
strtcpifc intnetadr('192.168.0.2')

You should now add a Default Gateway (or route) to your AS/400 configuration. This would allow the AS/400 to route to your Internet service provider the conversations which cannot be handled on the local network.
From the menu in Figure 2 select option 2. Work with TCP/IP routes:
Work with TCP/IP Routes
Type options, press Enter.

Figure 5 - Work with TCP/IP Routes

select option 1=Add to add a default route (substitute our sample value with your; see your checklist):
Add TCP/IP Route (ADDTCPRTE)
Type choices, press Enter.

3. Defining names and tables
   You are now going to define the AS/400 host name, its domain name, and its DNS server addresses.
   From the menu in Figure 2 select option 12. Change TCP/IP domain information (or prompt command chgtcpdmn); please substitute our sample values with your; see your checklist.
   Change TCP/IP Domain (CHGTCPDMN)
   Type choices, press Enter.
   Host name. . . . . . . . . . . . 'myas400'
   Domain name. . . . . . . . . . . 'mydomain.it'

   '194.20.8.4'

Figure 8 - Change TCP/IP Domain

Please note that the host name is up to you; it may be different from the one you display with command dspneta.

Now you have to update the host table with the host name of your AS/400.
From the menu in Figure 2 select option 10. Work with TCP/IP host table entries (or use command addtcphte, see Figure 10):
Work with TCP/IP Host Table Entries
Type options, press Enter.

It's important that you specify two host names:
the full one, in the format host_name.domain_name
and the domain_name by itself
to allow a correct routing of the electronic mail from the service provider.
after this, the screen Work with TCP/IP Host Table Entries looks as follow:

You should now specify the User ID and Address that the mail services will use to route mail that have an internet address as recipients. Operate as follow:
Enter command chgdsta (Change Distribution Attributes) and press F4. Make sure that the Distribution Attributes are as follow:
Change Distribution Attributes (CHGDSTA)
Type choices, press Enter.
Keep recipients . . . . . . . . *BCC *SAME, *BCC, *ALL, *NONE

4. Autostarting the TCP/IP servers
   While some TCP/IP servers are already configured for autostarting at the TCP/IP start, some other are not. These are:
   the HTTP server (WEB server), the SMTP server (e-mailer towards the Internet), and the POP3 server (e-mailer towards the internal users). This is how you may autostart these three servers.
   Use command go tcpadm to display the TCP/IP Administration menu

About Mail Service Framework (MSF)
MSF controls the AS/400 mail services.
It starts at IPL time.
However, as you just changed the TCP/IP configuration, you have to restart it by entering the following commands
endmsf option(*immed)
strmsf
For more information about MSF, please check IBM AS/400 redbook SG24-4703 AS/400 Electronic-Mail Capabilities .

5. Autostarting TCP/IP at IPL time
   Before OS/400 V4R4, to autostart your TCP/IP at IPL time, you have to add some instructions for the QSTRUP startup program.
   Starting with V4R4, you may obtain the same by adding an autostart job entry to subsystem QSYSWRK.
   Enter the following commands
   grtobjaut obj(qsys/strtcp) objtype(cmd) user(qpgmr) aut(use)
   chgjobd jobd(qsys/qtocstrtcp) jobq(qsys/qsysnomax)
   addaje sbsd(qsys/qsyswrk) job(struptcpip) jobd(qsys/qtocstrtcp)
