<p><span style="font-size: 10pt;">Hi<br>
I'm having one server at local LAN that I'm serving with IP's. I'm now
trying
out a a virtual server from a hosting provider, and aiming to use that
as a
redundant dhcp-server. When installing dhcpd on it I ran into problems.
The
public network interface of the server is a p-t-p one, with a broadcast
set to
0.0.0.0.<br>
I guess that the hosting supplier is using XEN or similar to provide
the
service.<br>
This is what I've got:<br>
<br>
A Ubuntu 8.04 LTS server with isc-dhcpd-V3.0.6.<br>

The dhcpd.conf file is copied from the working server and I have added:<br>
<br>
subnet 79.99.1.114 netmask 255.255.255.255 {<br>
}<br>
<br>
<br>
but when restarting dhcpd I get the following message in dhcpd I get
the
following message:<br>
<br>
Sep 19 22:30:04 hera dhcpd: No subnet declaration for venet0:0
(0.0.0.0).<br>
Sep 19 22:30:04 hera dhcpd: ** Ignoring requests on venet0:0. If this

Sep 19 22:30:04 hera dhcpd: you want, please write a subnet

Sep 19 22:30:04 hera dhcpd:<br>
Sep 19 22:30:04 hera dhcpd: Not configured to listen on any interfaces!<br>
<br>
<br>
<br>
Does anyone has suggestion how I should configure to get the server to
listen
to the venet0:0 interface?<br>
The router on my main network is configured to forward dhcp-requests to
my
"redundant" server, so this is not a problem.<br>
<br>
<br>
Thanks in advance.<br>
