Post OS installation configuration
« on: November 25, 2010, 12:17:12 PM »
Hello friends,

I've installed AIX 5.3 TL05 on a 275 machine and trying to make it available on LAN. I used
smitty mktcpip command to setup host name and its ip address (as defined in NIS server). Then i edited the
/etc/resolv.conf (actually i had to create it since it wasn't already there) and added the nameserver address and the domains in it. Now, when i reboot the server, it goes into failsafe session saying i may need to edit TCPIP configurations using smit mktcpip command. I check the /etc/hosts file also, which has the defined name and IP address of the server. But the server is neither pingable nor is able to ping any other server on the LAN.

I'm confused.. I think there is one more setting remained and/or some some setting is done wrong. Please help..

                                         Minimum Configuration & Startup

                  To Delete existing configuration data, please use Further Configuration menus

Type or select values in entry fields.
Press Enter AFTER making all desired changes.

                                                        [Entry Fields]
* HOSTNAME                                           [x054]
* Internet ADDRESS (dotted decimal)                  []
  Network MASK (dotted decimal)                      []
* Network INTERFACE                                   en0
           Internet ADDRESS (dotted decimal)         []
           DOMAIN Name                               []
  Default Gateway 
       Address (dotted decimal or symbolic name)     []
       Cost                                          [0]                                                        #
       Do Active Dead Gateway Detection?              no                                                       +
  Your CABLE Type                                     N/A                                                      +
  START Now                                           no                 

You need to fill all these fields. The NAMESERVER field should create /etc/resolv.conf for you. Since it was not there, something went wrong when you did it the first time.

to clean everything up - and "restart"

From the console!!!

# rmdev -dl inet0
# rmdev -dl en0
# rm /etc/resolv.conf
edit /etc/hosts ## to make sure the hostname entry is correct

Add the following to /etc/netsvc.conf

# cfgmgr

# smitty mktcpip

Be sure to fill in all the entries.

If you have more than one interface use:

# smitty inet

for additional interfaces
