Subnet Zero Enable in HPUX 10.20

[roobala]

Dear All,

We are using Class C Ip address subnetted with /27 ie 255.255.255.224.

In that We have so many network Equipments and HP servers in diff Subnets.

We wanted to configure one HP Server(A180C, HPUX 10.20) in the First Subnet ie Subnet 0, which IP Add will be
*.*.*.2 with Subnet mask of 255.255.255.224.

If I configure and restart the server lan card is getting unconfgiured automatically.

For Similar problem in HPUX 11.00 We had enabled one parameter in /etc/rc.config.d/nddconf

How to do the same in HPUX 10.20,
there is no ndd command or nddconf file.

nettune command didn't help.

Any help,
Thanks in Advance,
Roobala

Hi,

If you wanna violate rfc1122

Set the kernel parameter to:

adb -w /stand/vmunix /dev/kmem < check_bcast_addr/W 0
check_bcast_addr?W 0
end

This should come back with a comment saying:

check_bcast_addr 1 = 0

You need the Absolute Debugger (ADB) code to override the default settings
that ensure Internet Protocol (IP) addressing conforms to the rfc1122.

Hi,

if you want to enable subnet 0 on HPUX 10.20, you should use the nettune command.

nettune -s ip_check_subnet_addr 0

If you want to enable subnet 0 on server's reboot you should write the script with this command and put it in /sbin/init.d.
This script must be started before initialize LAN interfaces.
