Something changing BOOTPROTO from dhcp to static

[gnomeAware]

Hello,

I deploy a new VM from a template on ESX 5.5. After I do my initial configuration something changes the BOOTPROTO in the ifcfg-eth1 configuration file from dhcp to static. Any ideas?

(Not sure why HWADDR is in there twice - this is the cfg file create by the OS)

After this last reboot the server doesn't have an IP address because the cfg file has

What changed the BOOTPROTO to 'static'

I am not sure, but I would wonder about

[root@theTemplate network-scripts]# cat ifcfg-eth1
HWADDR=""
ONBOOT=yes
BOOTPROTO=static
PEERDNS=no
USERCTL=no
HWADDR=""

If you look at http://linuxgazette.net/153/prestia.html two things are "Required" - DEVICE and BOOTPROTO - everything else is optional. It does not say DEVICE. Why does it say BOOTPROTO=static here? The calls can be static/dchp/none.

It says:

If you want to use a DHCP-assigned address, your /etc/sysconfig/network-scripts/ifcfg-eth0file would look something like this:

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=08:00:27:4B:3B:06
ONBOOT=yes

Do you not specify and address for the Ethernet device?

The problem, in a nutshell, is that I set it to BOOTPROTO=dhcp and after a reboot it's set to BOOTPROTO=static. I'm trying to figure out what's changing it during a reboot.

PROBLEM SOLVED. I found a script in the VMware template that's tweaking the ifcfg-ethx files. This was put there by someone in our lab trying to be creative.

Thanks for the help.
