RE: [leaf-user] Question: Bering static DHCP configuration

2003-08-05 Thread Greg Playle
  RTFM rides again  I found everything I needed in the DHCP man pages.

The deny unknown-hosts command was what I wanted.

It's up to the rest of the packages to reject traffic from "unknown" hosts that are 
using a fixed IP that would otherwise be on the subnet.

Subject:        [leaf-user] Question: Bering static DHCP configuration

Thank you to all that have helped me learn a bit as I go.

My question now is:  I'd like to configure the internal network to ONLY 
assign IP addresses to certain machines.  I don't seem to have it correctly 
configured.  Could someone point me to something to read / learn about 
this?

I've checked the FAQ, read the User Guide and the Installation Guide, and 
Googled, but don't seem to find what I'm after.

[leaf-user] Question: Bering static DHCP configuration

I've got DHCP running, and assigning IPs quite nicely.

Unfortunately, it's also assigning IPs to what I think are "other" hosts. 
 I thought that, by only assigning particular IPs to particular MACs, the 
others would not receive addresses.

That leaves me with some options:
- restrict the netmask to only those few addresses
- somehow change the subnet mask.
- something else that restricts which IPs get assigned to which MACs

What haven't I learned yet?

My dhcp.config is like this:

dynamic-bootp-lease-length 604800;
max-lease-time 1209600;

host FirstHost {
hardware ethernet 00:00:00:00:00:00; # where the MAC addr is
fixed-address 192.168.1.1;
}

host SecondHost {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.1.2;
}

host ThirdHost {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.1.3;
}

#host ExcludeHost {
#   hardware ethernet 00:00:00:00:00:00;
#   fixed-address 192.168.1.4;
#}

subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.254;
option domain-name "name";
option domain-name-servers 192.168.1.254;
range 192.168.1.1 192.168.1.3;
}
