DHCP Server

A

Airost

Hello,

Is there any possibility that DHCP server can listen on specific network interfaces? On my school lessons we were setting up DHCP server in Linux and there you can point to network interface to issue IP addresses and in FreeBSD I tried same way but no success. When I start or restart dhcpd I get following:

Code: 
root@ldrive:/usr/local/etc/unbound # service dhcpd restart
/etc/rc.conf: ifconfig_vm-public=inet 10.0.0.100 netmask 255.0.0.0: not found
/etc/rc.conf: ifconfig_vm-public=inet 10.0.0.100 netmask 255.0.0.0: not found
Stopping dhcpd.
Waiting for PIDS: 3623.
Starting dhcpd.
Can't listen on tap3 - dhcpd.conf has no subnet declaration for 10.0.0.40.
Can't listen on tap2 - dhcpd.conf has no subnet declaration for 10.0.0.30.
Can't listen on tap0 - dhcpd.conf has no subnet declaration for 10.0.0.20.
Can't listen on tap1 - dhcpd.conf has no subnet declaration for 10.0.0.10.
Can't listen on vm-public - it has no IP address.
Listening on bge1 (172.16.0.1).
Can't listen on bge0 - dhcpd.conf has no subnet declaration for 192.168.2.11.

My dhcpd.conf is as follows:
Code: 
# dhcpd.conf
#INTERFACES="bge1 tap0 tap1 vm-public"

I wanted to create 2 subnets one to be used on interface bge1 -> 172.16.0.0/16 and the other one to be used for my virtual machines with subnet 10.0.0.0/8 on interfaces tap0, tap1, tap2, tap3 etc.

When I also start my Virtual Machines, interfaces and virtual router don't have IP address assigned. I have to manually type:
ifconfig tap3 inet 10.0.0.40 netmask 255.0.0.0

What am I missing?
 
With current rc.conf it should listen only on bge1, and from what I see in console it is trying to listen on all devices unless I got message "Can't listen on XXX it has no subnet declaration XXX.XXX.XXX.XXX" wrong?

Next thing if I change rc.conf line:
dhcpd_ifaces="bge1" to dhcpd_ifaces="bge1 tap0 tap1 tap2 tap3" then:

ifconfig_tap0="inet 10.0.0.20 netmask 255.0.0.0"
ifconfig_tap1="inet 10.0.0.10 netmask 255.0.0.0"
ifconfig_tap2="inet 10.0.0.30 netmask 255.0.0.0"
ifconfig_tap3="inet 10.0.0.40 netmask 255.0.0.0"
 to

ifconfig_tap0="DHCP"
ifconfig_tap1="DHCP"
ifconfig_tap2="DHCP"
ifconfig_tap3="DHCP"
 and I also add another subnet in dhcpd.conf, how will DHCP server know which subnet to use on what network interface?

You only have a pool with subnet 172.16.0.0 netmask 255.255.0.0, so this only applies to the bge1 interface (because it has an IP address in that range). In order to serve a 10.0.0.0/8 pool you will need to have an interface in that range for the DHCP server to bind on. Those tap* interfaces are the interfaces from your VMs. You don't bind your DHCP server to other hosts on your network, so why would you do this with a VM?

You do understand how DHCP works?

Dynamic Host Configuration Protocol - Wikipedia

en.wikipedia.org en.wikipedia.org

The way you've set things up causes both 10.0.0.0/8 and 172.16.0.0/16 networks to be on bge1. It's generally a bad idea to run two different subnets on the same broadcast domain.

What you could do, is to remove igb1 from the vm-public bridge. Then assign 10.0.0.1/8 to vm-public. Configure a 10.0.0.0/8 pool in dhcpd.conf, bind the DHCP server to igb1 (for the 172.16.0.0/16 pool) and vm-public (for the 10.0.0.0/8 pool).
 
Can't listen on bge0 - dhcpd.conf has no subnet declaration for 192.168.2.11.
Click to expand...

For every vlan and subnet that you want to provide DHCP you need a separate declaration like:
Code: 
subnet 172.16.0.0 netmask 255.255.0.0 {
    range 172.16.0.120 172.16.0.200;
    option domain-name-servers 8.8.8.8, 8.8.8.4;
    option routers 172.16.0.1;
    option broadcast-address 172.16.255.255;
    option ip-forwarding on;
    default-lease-time 600;
    max-lease-time 7200;
    }
assuming your gw is 192.168.2.11 it's not necessary the dhcp server to be the gateway
Code: 
subnet 192.168.2.0 netmask 255.255.255.0 {
    range 192.168.2.200 192.168.2.210;
    option domain-name-servers 8.8.8.8, 8.8.8.4;
    option routers 192.168.2.11;
    option broadcast-address 192.168.2.255;
    option ip-forwarding on;
    default-lease-time 600;
    max-lease-time 7200;
    }
 
I followed SirDice and after system reboot from system startup ifconfig I get:

I did have to manually set IP to vm-public

root@ldrive:/home/airost # ifconfig vm-public inet 10.0.0.1 netmask 255.0.0.0

I restarted dhcpd to see output:

root@ldrive:/home/airost # service dhcpd restart
Stopping dhcpd.
Waiting for PIDS: 3242.
Starting dhcpd.
Can't listen on tap3 - it has no IP address.
Can't listen on tap2 - dhcpd.conf has no subnet declaration for 0.0.0.0.
Can't listen on tap1 - it has no IP address.
Can't listen on tap0 - it has no IP address.
Listening on vm-public (10.0.0.1).

Why vm-public don't set 10.0.0.1 on start up as it's set in /etc/rc.conf? and why dhcpd doesn't issue IP addresses to hosts tap0, tap1, tap2, tap3 as stated as below:

host tap0rockyvm { hardware ethernet 58:9C:FC:10:F9:42; fixed-address 10.0.0.20;}
host tap1win2012servervm { hardware ethernet 58:9C:FC:10:20:2E; fixed-address 10.0.0.30;}
host tap2ubuntuvm { hardware ethernet 58:9C:FC:00:27:08; fixed-address 10.0.0.40;}
host tap3win2022servervm { hardware ethernet 58:9C:FC:10:FF:F6; fixed-address 10.0.0.50;}
