Can I use remote bsd isc dhcp server

Hi,

While I was installing katello 2.1 from scratch on test today, I deleted
the VM 2.0 was installed to.

After that my whole ovirt/gluster test environment went down. This is
due to the fact that the foreman VM is the dhcp server and the leases
expired.
Now everything has lost it's ip and is unreachable.

This is a major pita and will cause many problems when the non HA
foreman environment is unavailable for a bit of time even when you're
not replacing your katello/foreman environment.

Can I use the external clustered ics dhcp we have running on bsd?

Met vriendelijke groet, With kind regards,

Someone correct me if I am wrong, but our smart proxy should run on BSD
systems. Make sure you install ruby 1.8+ with all the dependencies (use
bundler for that) and try that.

Does not need to be "remote". Also you could try to setup ISC DHCP
remotely, but you need to make sure both omshell and local file access
to dhcpd.conf and leases files does work (via NFS for example). But this
setup will be very slow.

Thanks for the tip Lucas, but I don't wan't to mess too much with our
BSD based firewall cluster. They are running extremely stable.

I think I will revert to Internal IP DB and convert everything to static
ip's. The reason I hardly ever use DHCP except for home/office use is
becoming clear to me again.

When something happens with dhcp you kill your whole nicely redundant
cluster. This can happen when the dhcp server is down for a while or
another rogue dhcp server appears on the same network.

Also with dynamic ip's it's hard to get things like NAT and iptables
rules tight. Until we have software defined dynamic firewall rules, but
there are no tools yet to this. For firewalld management and policies I
have been talking to the FreeIPA team already, so maybe we'll be able to
do that in the future.
