ISC DHCP for relay agents

kg flag

I would like to configure DHCP server for my networks, but in the same time, i don't want to setup dhcp server on the network where the server itself is.

DHCPD insist to configure subnet declaration for the network of the ens192 interface (which i really dont want to as there is another DHCP server (on Windows Server)).

Not configured to listen on any interfaces!

Is there any way to configure only those networks with realy agents and ignore ens192 network?

Interfaces:

2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:50:56:9c:1d:4a brd ff:ff:ff:ff:ff:ff
    inet 10.144.0.45/24 brd 10.144.0.255 scope global noprefixroute ens192
       valid_lft forever preferred_lft forever

dhcpd.conf:

ddns-update-style interim;
ignore client-updates;

# MNGT VLAN2 via 10.145.2.1
subnet 10.145.0.0 netmask 255.255.255.0 {
        range 10.145.0.2 10.145.0.253;
        option routers 10.145.2.1;
        option broadcast-address 10.145.0.255;
        option domain-name-servers 10.144.0.45;

# VLAN 10 via 10.145.10.1

        range 10.145.10.2 10.145.10.253;
        option routers 10.145.10.1;
        option broadcast-address 10.145.10.255;
        option domain-name-servers 10.144.0.45;
}

# VLAN 9 via 10.145.9.1
subnet 10.145.9.0 netmask 255.255.255.0 {
        range 10.145.9.2 10.145.9.253;
        option routers 10.145.9.1;
        option broadcast-address 10.145.9.255;
        option domain-name-servers 10.144.0.45;
}

# VLAN 8 via 10.145.8.1
subnet 10.145.8.0 netmask 255.255.255.0 {
        range 10.145.8.2 10.145.8.253;
        option routers 10.145.8.1;
        option broadcast-address 10.145.8.255;
        option domain-name-servers 10.144.0.45;
}

I think you can define subnet without any range for the server network and it should work as you want.

# DHCP for the server network
subnet 10.144.0.0 netmask 255.255.255.0 {
}

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
