dhcpd server

Message

vaguy02 · Post by **vaguy02** » Tue Mar 01, 2005 2:50 am

I'm setting up a firewall/router at home and I'm trying to set up the dhcpd server. I followed the home router guide, but on start up when it starts to run the dhcpd process I get the red !! marks on the side and I've tried with My xp box and it won't grab a dhcp address. But if I put a static address in the xp box it gets on the internet fine, so I know most of the settings are right. Any help?

my /etc/dhcp/dhcpd.conf:

authoritative;
ddns-update-style ad-hoc;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.100 192.168.0.250;
default-lease-time 259200;
max-lease-time 518400;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
option domain-name-servers 192.168.0.1;
}

Just some nomenclature comments:

DHCP: Dynamic Host Configuration Protocol, protocol by which a host can assign clients IP addresses in a dynamic fashion
dhcpcd: DHCP client deamon, deamon which contacts a local DHCP server to recieve an IP address
dhcpd: DHCP deamon, deamon which runs on the DHCP server and assigns IP's

I thought I got all of the different terms right, the differences between dhcpd and dhcp but if I didn't. I'm sorry. I hope someone can still help

I was just giving you a little info that's all. I still understood what you were talking about. I wish I could give you some specifiic help on your problem but I've never had to set up a dhcp server, I use a standalone firewall/router that also acts as a dhcp server.

That's actually what I'm trying to do right now, is to set up a firewall/router standalone gentoo box that has a dhcp server so my xp box and roommates can dhcpcd an address from it.

My standalone came preconfigured though, it's a Linksys. Since it has firewall, router, and wireless capabilities out of the box, it was just easier.

try ddns-update-style interim; instead of ad-hoc and see.

read the manpage for dhcpd (or maybe dhcp, I forget) it will list 2 things you need compiled into the kernel for it to work

I tried the interim but I still don't get any results. Any other ideas?

look in your logs and tell us what it's problem is and perhaps we can figure it out.

This is what mine looks like and it works perfectly. Hope it helps.

ddns-update-style ad-hoc;
allow bootp;

default-lease-time 6000;
max-lease-time 10000;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
#log-facility dhcpd;

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.20 192.168.1.250;
option routers 192.168.1.1;
option domain-name "xxx.xxx.xxx";
option domain-name-servers a.b.c.d, a.b.c.d, a.b.c.d;
}

your dhcpd.conf seems to be alright !!

but take a look at your networkcard-configuration. Perhaps the eth1 (for example) is not set correctly. You will have to set a static IP to this interface. with f.e.

Code: Select all

ifconfig eth0 192.168.0.1

or add

Code: Select all

iface_eth1="192.168.0.1 broadcast 192.168.0.255 netmask 255.255.255.0"

to your /etc/conf.d/net .

Take a look at your /etc/conf.d/dhcpd !
There has to be set wich networkinterface will provide your dhcp !

Code: Select all

IFACE="eth0"

is set in mine.
