Hello,

I have submitted this question to the sourceforge mailing list for opennms, but it is not getting posted for some reason, so I'm posting it here in the event that someone here has run into this issue before:

I have recently deployed OpenNMS across a network, and all desired functions are working well except for the DHCP discovery. I have looked through the FAQ and through the discussion lists and have seen others mention this error. The suggested resolutions are to ensure that dhclient (or any form of dhcp) is not being used to obtain the OpenNMS server's IP address and to make sure that the MAC address of the OpenNMS server is listed in dhcpd-configuration.xml. I tried both of these resolutions and neither worked. I was originally running OpenNMS as a test on a Xen virtualization box but moved it onto it's own hardware to make sure that none of Xen's bridging was causing problems, but that did not solve the problem either.



The error I get in the capsd.log is:



2007-04-19 13:04:45,116 ERROR [Capsd Suspect Pool-fiber0] Poller: IO Exception during socket connection establishment with DHCP client daemon.

I am currently running on Debian Etch with the following /etc/network/interfaces configuration:



# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).



# The loopback network interface

auto lo

iface lo inet loopback



# The primary network interface

allow-hotplug eth0

iface eth0 inet static







I have the correct IP/DNS/Gateway addresses configured in this file as well.



If I run ps -auwx and grep for dhclient or just dh nothing is returned.



I have tested 2 different boxes that are currently functional dhcp servers and neither of them are detected as dhcp servers in OpenNMS. I am currently running version 1.3.2.



Does anyone have any suggestions for me to try or is this looking like a bug?



My dhcpd-configuration.xml file looks like this:



<DhcpdConfiguration

port="5818"

macAddress="00:18:FE:1A:99:12"

myIpAddress="127.0.0.1"

extendedMode="false"

requestIpAddress="127.0.0.1">

</DhcpdConfiguration>





Thanks in advance for any assistance.

you're really *much* better off on the mailing lists, only thing i could suggest, as an opennms user, is that isn't dhcp disabled in the services.xml file by default?

I do have it enabled in the service-configuration.xml file. I didn't think I would get much response here to this particular question, it was just an act of desperation . Thanks for your response.

I recently had a similar issue with Gentoo. It got solved after an update. Before that, I was able to get dhcp to work by using this command

dhcpcd eth0

There is a second command:

dhcpcd -H eth0

That should follow the first one but I never needed it because dhcp started functioning right after the first command.

Unfortunately, I had to reissue the command on each reboot.
