This is an IBM p9 system with AIX 7.2. End user rebooted the system and it came up with the auto config (normally seen the first time you boot a system) on the console. Unfortunately they then selected auto config tcpip and it did, change ip address of ent0 to 0.0.0.0. After finding that I used smit to change it back to what it was supposed to be. However, now each time the system is reboot if always goes back to 0.0.0.0! I can't find what is doing this or how to make the change back to the "real" ip permanent.

Any suggestions.

I hate to ask the incredibly obvious, but have you tried setting the correct address with smitty tcpip, selecting "Minimum configuration and startup" ?

If you've done that, run smitty chinet, to set the address without initializing other server parameters.

I did the first using smit with no success.  Will give the second a try on Monday.

I suspect the auto config program left a script somewhere that is executed on reboot. I have checked the bootlog, inittab, rc.d but have not been able to identify anything that could be doing it.

I tried "smitty chinet" to set the ip, but that also does not work. On reboot the ip still goes back to 0.0.0.0.

Turned out to be a dhcp issue being set when it should not have been.
