C-Class Subnetting

[3in2te1n]

I tried to assign 255.255.255.248 Netmask on my HP-UX11 Machine. But it´s not functional. I get the following Error message:
lan0 interface: ifconfig: ioctl (SIOCSIFNETMASK): bad value

Any ideas?

Hi,

What IP address are you using.

The IP-Range is 192.168.1.0 - 7. Host-Address is 192.168.1.4
I´d read that ndd perhaps fix this problem. But I also readed that ndd includes a security problem.

Are there any other solutions?

Thanks in advance!

Hi,

I've not been involved in many problems on HP-UX regarding subnets, however my thoughts are that when you subnet, you lose two address ranges, the first and the last. You are trying to use the first which is not valid.
Below is the subnet table for you, try using one of the other subnet ranges and see if you get the same error.

Thanks a lot!!! That was it. The last range is also invalid.
But why? Isn´t it wastefulness?

I think this is just HP-UX. ;-) Other Unix-/Linux-Systems don´t have problems with these configuration.
