I would like to have a subnet on each interface and therefore dhcpd to
span both interfaces.
For that purpose I use /etc/dhcpd.interfaces where i have:
vr0
vr1
But i can't find a man page on this file so I can't see if it make a
difference whether I write:
vr0 vr1
or
vr0
vr1
So my question is:
Is there a difference ?
No. And if you want dhcpd to run on every interface, you can
just remove this file or leave it blank.
Is it just me who can't find documentation on this ?
It's mentioned in dhcp(8).
What's logged?
What's in /etc/dhcpd.conf?
The reason why I ask is because of a strange behaviour of my dhcpd
serer, or at lease my interfaces.
I run a Inet gateway on a soekris 5501
I have wan on vr0 with the following hostname file:
-----
dhcp NONE NONE NONE
-----
I would like to have a subnet on vr1 with the hostname file:
-----
inet 192.168.3.1 255.255.255.0
----
I would like another subnet on vr2 with the following conf:
----
inet 192.168.2.1 255.255.255.0
----
My dhcpd.conf is as follows:
-------
#Globals:
default-lease-time 600;
max-lease-time 600;
authoritative;
#Work subnet
subnet 192.168.3.0 netmask 255.255.255.0 {
option domain-name "work.local";
option routers 192.168.3.1;
option domain-name-servers 212.xxx.xxx.xxx, 212.xxx.xxx.xxx; #"removed
for privacy"
range 192.168.3.50 192.168.3.200;
}
#employ subnet
subnet 192.168.2.0 netmask 255.255.255.0 {
option domain-name "employs.local";
option routers 192.168.2.1;
option domain-name-servers 212.xxx.xxxx.xxx, 212.xxx.xxx.xxx; #"Removed

range 192.168.2.50 192.168.2.200;
}

I use pf to handle the nat and some filtering my pf rules is as follows:
---------
##### Define the interfaceses and networks ####
wan_if="vr0"
work_if="vr1"
worknet = $work_if:network
employs_if="vr2"
employsnet = $employs_if:network
#### Service containers ####
#Employes lan
tcp_services_employs = "{ssh, domain, www, pop3, imap, imaps, auth,
https, pop3s}"
udp_services_employs = "{domain, imap, imaps}"
icmp_types="echoreq"
#work lan
#### Nat ####
#Remember to enable ip.forwarding in /etc/sysctl.conf
# Nat employs to the ext if
nat on $wan_if from $employsnet to any -> ($wan_if)
#nat the work lan as well
nat on $wan_if from $worknet to any -> ($wan_if)
#### Rules ####
## This machine ##
# This machine provides smb from worklan and ssh from any
#ssh
pass quick proto tcp to any port ssh
#SMB
#smbname port 137 tcp and udp
pass in on $work_if proto {tcp, udp} from $worknet to $work_if port 137
#nbdatagram

## Employes lan ##
#add icmp
#By befault close all in both directions
block in on $employs_if

I have attached to windows xp clients by crossed cable one to each if
(vr and vr2)
The fun begins here, when i turn on and off the windows machines a
couple of times one of the can't obtain a IP. It actually brings down
the whole interface. I can't attach another BSD machine and run
dhclient. Even if I set my own ip-addr on the client and starts to ping
I can't reach the other machine. It dosn't even answer on arp on that if.
This is only solved by rebooting til gateway machine.
I have tried all combinations. like switching cables interfaces and so
on. But I can't relate it to one windows machine, or one interface on
the gateway, and it happens even thought I switch cables.
I don't get any messages in /var/log/daemons from the interface after it
is down but the one still working keeps renewing.
I don't get any warnings in dmesg
I just attach it in the bottom...
I am realy stuck. I have tried to disable pf before and after the
interface has gone down, but still the same. I even tried to take the
take the disk to my soekris 4801 and switched the interface names and so
on, but still the same...
BTW: I use openbsd 4.2 and I have removed the interfaces from
dhcpd.interfaces so it looks in the following way:
--------
# $OpenBSD: dhcpd.interfaces,v 1.1 1998/08/19 04:25:45 form Exp $
#
# List of network interfaces served by dhcpd(8).
#
# ep0
# ed0 le0
# de1
-------
Any suggestions ?
Kind regards:
Kasper
