Setting "final route_gateway[0]" automatically...

[Jeff Carlin]

I have a custom config file that I include in my INDEX that sets up the "standards" for disk layout and networking. Here at Kmart, we have many subnets, each with there own gateway. For each subnet the IP of the gateway is always 1. The subnet will often be different.

If I don't specify anything for the "final route_gateway[0]=xxx.xxx.xxx.xxx" it will always default to the gateway on the ignite server. This is okay for that subnet, but I am igniting HP's over 18 different subnets. How can I derive the final route_gateway value automatically from the IP address that I want to set the target server to? For example, say the target is 148.162.196.100 and I want the final route_gateway[0]= to automatically be 148.162.196.1

Is it possible to manuiplate strings in the config files and make a new string for the route_gateway? How would I do this?

Yes, use perl.

Hi,

I think you can easily accomplish this in your post-install script. In that, you'll grep for "route_gateway" keyword in /etc/rc.config.d/netconf file and change the IP to that of lan?[0] replacing last octect to 1.

Hi,
We have the same situation and have achieved it by creating a 'settings_cfg' file that contains the IP ranges of all our subnets, and sets the final_route_gateway accordingly. For example:-

ip_addr[] ~ "10.1.10"
{
final route_gateway[0] = "10.1.10.1"
final route_destination[0] = "default"
final route_count[0] = 1
}

ip_addr[] ~ "10.1.11"
{
final route_gateway[0] = "10.1.11.1"
final route_destination[0] = "default"
final route_count[0] = 1
}

Hope that helps,
Nei
