<P><FONT SIZE=2>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 is not what<BR>
Sep 19 22:30:04 hera dhcpd: you want, please write a subnet declaration<BR>
Sep 19 22:30:04 hera dhcpd: in your dhcpd.conf file for the network segment<BR>
Sep 19 22:30:04 hera dhcpd: to which interface venet0:0 is attached. **<BR>
Sep 19 22:30:04 hera dhcpd:<BR>
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>
