We have an AIX 5.3 server where I have set static IP but after every 24 hrs it is setting some other IP to this machine (I believe some DHCP process is running in the background every 24 hrs).
I want to set the Static IP permanent to this machine, can some one help me where the problem is and how can i set the static IP permanently.
Usually this doesn't happen on it's own. Is the box rebooted every 24h so that it asks for IP via DHCP or is there a mysterious cron job running every 24h ?
We are not restarting the machine, even if login from remote console after 24 hrs (time starts after i activate static IP) it is logging out and changing the IP.
Here is my CRONTAB looks like

Hm, then I currently have no further idea, sounds mysterious...
What does (insert your interface where I have en0)
show?
Also you can check if any dhcp related stuff is running:
TBH, I never configured dhcp on any server since I think that's nonsense and never had to but nevertheless, let see if you can find anything.
