Doesn't mean that it will answer.
I saw your previous posts which has the authoritative declaration.
Authoritative (from my experience) means that if a client had
previously gotten an address, a non-authoritative server won't correct
the client's lease. Think of a roaming laptop or a PDA with wifi.
An authoritative server will say No, that won't work, then the
client will release any knowledge of the previous IP, and search for
new dhcp servers.
Since you weren't getting leases when your firewall was disabled, I
would lean toward a misconfigured dhcpd.conf. I don't think I've seen
in the same post:
ifconfig rl1
cat /usr/local/etc/dhcpd.conf
Please provide these. Thanks.

Ok. Chomping heavily .. I've just reviewed this thread through four
digests, rather a top-posting, multi-tail-quoting mess. Please trim
quotes to the necessary then add your response; we've seen the rest.
mac# $ dhcping -h 00:23:32:dc:72:19 -s 192.168.1.1
no answer
bsd# tcpdump -i rl1 -n port 67 or port 68

You could perhaps usefully add 'or arp' to that tcpdump.
Like your earlier tcpdump; the Mac's asking and 192.168.1.1 is not
responding. I don't think anyone's asked yet what you get from:
# netstat -finet -an | grep 67
ie, is dhcpd really listening? something like ..
udp4 0 0 192.168.1.1.67*.*
If not, there's your problem .. if so, looks like your firewall might be
blocking those packets from reaching 192.168.1.1 (OR its responses back)
If dhcpd is running, even if it's misconfigured, I'd expect to see some
response if it's receiving requests.
bsd# arp -a
? (192.168.1.234) at 00:23:6c:86:41:d9 on rl1 [ethernet] - this is my
MacBook
? (192.168.1.1) at 00:13:8f:86:2f:64 on rl1 permanent [ethernet] - this is
the layer 3 switch
So your switch and your rl1 interface have the same IP? That can't be good,
can't see why it would affect things when the switch isn't in action though.
# sockstat -4l | grep dhcp
dhcpddhcpd 4747 7 udp4 *:67 *:*
Yeah sockstat's always useful too; both it and netstat -a will show udp
port 67 listening if dhcpd's running (right).
From a later message ..
pool {
option domain-name-servers cns01.hdsnet.hu;
max-lease-time 300;
range 192.168.1.200 192.168.1.253;
allow unknown-clients;
}
}
.. it seems from the arp -a above that the Mac already has 192.168.1.234
which is within that range? However, concentrate on getting as far as
seeing return responses from dhcpd on port 67 to clients with tcpdump,
with your firewall momentarily disabled if need be ..

It looks awkward...
I don't recall ever seeing a pool inside a subnet declaration like this.
A subnet declaration can use all the declaration in your pool.
Pure curiousity, because I am not looking up the config syntax..
comment out (or delete) the pool { and } lines only. which bring the
statements to the subnet clause.
restart dhcpd, and retry
IIRC, pools are only useful if you have two pool definitions.
thanks... hope this works.

Re: dhcpd related issue
I had one more idea: try nmap on my dhcp server, and port 67 does not seems to
be opened, after I tried telneting in and my connection was refused:
$ telnet 192.168.1.1 67
Trying 192.168.1.1...
telnet: connect to address 192.168.1.1: Connection refused
telnet: Unable to connect to remote host
Than I disabled pf
# pfctl -d
No ALTQ support in kernel
ALTQ related functions disabled
pf disabled
Than I checked telnet/nmap again but still don't found any 67 port ever there.
I checked again that the dhcpd is running, and its up:
# ps ax|grep dhcp
958 ?? Is 0:00.00 /usr/local/sbin/dhcpd -cf /usr/local/etc/dhcpd.conf
-lf /var/db/dhcpd/dhcpd.lease
Any idea?

I had one more idea: try nmap on my dhcp server, and port 67 does not seems to
be opened, after I tried telneting in and my connection was refused:
$ telnet 192.168.1.1 67
Trying 192.168.1.1...
telnet: connect to address 192.168.1.1: Connection refused
telnet: Unable to connect to remote host
Than I disabled pf
# pfctl -d

ALTQ related functions disabled
pf disabled
Than I checked telnet/nmap again but still don't found any 67 port ever there.
I checked again that the dhcpd is running, and its up:
# ps ax|grep dhcp
958 ?? Is 0:00.00 /usr/local/sbin/dhcpd -cf /usr/local/etc/dhcpd.conf
-lf /var/db/dhcpd/dhcpd.lease
Any idea?

Hello,
I just configured my dhcpd but it gives no IP-s.
What had I done until now:
1. Installed isc-dhcp via ports
2. edited the /usr/local/etc/dhcpd.conf
option domain-name bsd;
option domain-name-servers my dns server ip;
option subnet-mask 255.255.255.0;

range 192.168.1.129 192.168.1.250;
option routers 192.168.1.1;
}
3. Added the following ones to /etc/rc.conf
ifconfig_rl1=inet 192.168.1.1 netmask 255.255.255.0
dhcpd_enable=YES
dhcpd_conf=/usr/local/etc/dhcpd.conf
dhcpd_ifaces=rl1
4. Opened the adequate port in pf
pass in log on rl1 inet proto tcp from 192.168.1.0/24 to 192.168.1.1 port =
bootps flags S/SA keep state
pass in log on rl1 inet proto udp from 192.168.1.0/24 to 192.168.1.1 port =

DHCP uses UDP, telnet uses TCP, no wonder you're getting refused.
Do you have bpf (Berkeley packet filter) compiled in the kernel?
dhcpd relies on bpf. Just a thought, although dhcpd would probably
shut down if bpf is unavailable.
As others have suggested, please post the output from ifconfig rl1,
and from netstat -rnf inet.
Than I disabled pf
# pfctl -d
No ALTQ support in kernel
ALTQ related functions disabled

Just another (silly) thought, does your pf setup allow UDP from
192.168.1.1:67 to *:68 over the rl1 interface?
Than I checked telnet/nmap again but still don't found any 67 port
ever there. I checked again that the dhcpd is running, and its up:

Did you restart dhcpd?
What's the output from fstat with respect to dhcpd?
The output should be something resembling:

dhcpddhcpd 18990 wd / 6 drwxr-xr-x1024 r

What happens if you disable pf temporarily?
2009/10/31 Dánielisz László laszlo_daniel...@yahoo.com:
Hello,
I just configured my dhcpd but it gives no IP-s.
What had I done until now:
1. Installed isc-dhcp via ports
2. edited the /usr/local/etc/dhcpd.conf
option domain-name bsd;
option domain-name-servers my dns server ip;
option subnet-mask 255.255.255.0;
authoritative;
default-lease-time 3600;
max-lease-time 86400;
ddns-update-style none;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.129 192.168.1.250;
option routers 192.168.1.1;
}
3. Added the following ones to /etc/rc.conf
ifconfig_rl1=inet 192.168.1.1 netmask 255.255.255.0
dhcpd_enable=YES
dhcpd_conf=/usr/local/etc/dhcpd.conf
dhcpd_ifaces=rl1
4. Opened the adequate port in pf
pass in log on rl1 inet proto tcp from 192.168.1.0/24 to 192.168.1.1 port =
bootps flags S/SA keep state
pass in log on rl1 inet proto udp from 192.168.1.0/24

Authoritative (from my experience) means that if a client had previously gotten an address, a non-authoritative server won't correct the client's lease. Think of a roaming laptop or a PDA with wifi. An authoritative server will say No, that won't work, then the client will release any knowledge of the previous IP, and search for new dhcp servers. Since you weren't getting leases when your firewall was disabled, I would lean toward a misconfigured dhcpd.conf.
