Interface showing 0.0.0.0

[Guest_imported]

hieeeeeeeeeeeeeee
In the last resort i am appearing in this forum.
One of my interface shows 0.0.0.0 when the machine
is booted.Once the iconfig command is run it become
o.k( or smit Tcpip menu is used).
But once machine is booted all gone.
we have removed and recreated the interface enx and
entx but useless.
Any ideas???

Some thoughts?

1)Patches...I would look for bos.net.*
---------------------
There was a bug on 4.3.1 being unable to resolve ip address 0.0.0.0 - the patch
is apar IX81053. But I don't know what level you are at?
------------------------------
But that is strange...it may be that one of your rc files is a bit messed?
2) Someone could have set dhcp to run? which lets you bring the network up
manually? Or didn't want the stuff in the ODM and set it up
to run rc.bsdnet instead of rc.net? Not kept in the odm?
---------------------
However, I believe it is a simple setting from smit that gets you in trouble...
BSD style network configuration puts all of your ifconfig and route
commands and such in /etc/rc.bsdnet. and then you can do with smit or
change manually
chdev -l inet0 -a bootup_option=yes
then nothing is set when you come up except what is in the rc.bsdnet file...
and you have to manually start everything...
3) I am not sure if an lsattr -El inet0 will show what it is set at....(not near a computer right now sorry) ....
------
4)You did the ifconfig en0 down
ifconfig en0 detach
rmdev -dl en0
rmdev -dl ent0
cfgmgr
Then went back into smitty tcpip and defined it there under minimum config? and ran it....
------------------------
Are you running
TCP wrappers?
Did someone set dhcp ?

5)Look in your rc.net file for the USE_DHCP= line
make a copy before you change anything...comment out the dhcp daemons?
if someone changed the USE_DHCP="1"
you have bsd turned on:
change to USE_DHCP="0"
Not sure if the same in 4.3.3...but in 4.2 and early 4.3 it was...

Or Set up as PPP?
-----------
6)I would also do an alog -o -t boot | more
and make sure that all the daemons came up etc.... without error?
lssrc -g tcpip
------------------------
Did the IP ever work? if it did, what changed? When did it change....

Just off the top of my head...maybe someone else has more suggestions...
Good LUck.
