Greeting,
can rarpd give a remove install client ip address with netmask?
I seems have problem with netmask because the ip address is class B and I
need a class C netmask. Is any way to fix this problem?
Any comments will be appreciated
Thanks in advance

Hi,
I use Red Hat 8.0. I wish to add the above line to my
routing table using the GUI tools they provide, but
when attempting to do this it just plainly does not
work.
The routing table I'd like is:
Kernel IP routing table
Destination Gateway Genmask Flags
Metric RefUse I
he correct netmask in the subnet declaration to get it to serve from
different ranges. I had noticed that you could pass an interface inon the
command line to have it listen on only one interface which is why I was
thinking you'd need to run 2 servers.
But yes, this sounds perfect. The second nic is

This is going to show my stupid newbieness, but regarding the below:

I wanted to revive this thread because I had the need for this recently,
but since I was a remote location (and I'm no network guy) I didn't have
the confidence. There was also one nagging issue regarding dhcp for this
setup that I wasn't sure about.
So let me explain the problem scenario.
I had
Why break things up into smaller (restrict the) numbers of hosts?
Sometimes you need to isolate computer groups for better network performance
(have the computers that talk to each other the most off in a corner where
they won't disturb anyone else), security (limit the damage that a vandal can
One thing before I start, you don't have to make the dhcpd range be the same
size as the number of IP's avaliable on the subnet. The netmask and dhcpd
range are independant. In fact, I leave out everything below a certain
number for machines (servers) that always have the same IP add

I'm going to sound very very ignorant, but, um, why? What is the
point in restricting a network to 1, 2, 4, 8, or 16 hosts? What is wrong
with just the simple 255.255.255.0 netmask?
Sendem my way, or to the list. I'll learn.

The same. I was just using "class C" as a reference point for a familiar
network size. It helps to forget all about classes, to be honest.
An 8-host sub

all three class. ABC

The 1st 5 bits stay the same and so are part of your netmask
1000 => 248
Also netmask's are always a string of 1's followed by a string of 0's.
Don't try mixing them up!

No. The netmask only defines the size of the network, not "where" in the
address space it is -- that's the job of the network address. If you

If you make your network 192.168.1.80 and your netmask 255.255.255.248
your broadcast address will be 192.168.1.87 and your usable addresses
will be 81 - 86.
As for why, try looking at these numbers in binary.

I'm trying to understand how netmasks work. We want to set up a small
pool of IP Addresses, and the only thing we can do is specify the network
and the netmask. They want the pool to start at 192.168.1.85, and have 5
usuable IP Addresses. What do I specify for the netmask, and

I have a block of 8 ip address.
from a class C. for example.
x.x.x.128 to 135
I make my network address x.x.x.128
my broadcast address x.x.x.135
but what do i set for my netmask? 255.255.255.???
how do i figure out the netmask for
something like this?
Thanks
