[webmin-l] DHCP + Failover + VRRP

[Filipe Cifali]

Hi,

I would like to do this kind of setup:

*dhcp server 1* delivers IPs and routes 192.168.0.1 to all his machines
*dhcp server 2 *is a secondary of* dhcp server 1* and only delivers IPs and
route if 1 goes down.

I understand that it would be needed an keepalive or something else to do
VRRP, so the route IP would "float" between server 1 and 2 as needed.

But I haven't found a module for it, would that be a bad setup or nobody
needed this yet?

The decision about doing VRRP of the route IP is because: if server 1 goes
down, server 2 can get his route and the internet doesn't stop for the
users.

Thanks in advance.

Before this gets answered, I would like to throw out there (my opinion) that this isn't and shouldn't be a Webmin kind of thing.



If you need this amount of redundancy, I would look elsewhere other than an Admin tool.

Hi Dave,

this is kinda of a simple setup in my opinion.

Webmin already worked with heartbeat before, why would it not be something
to look for if you can spare some hardware on it.

Heartbeat is a very old software, but we use it on some setups today
because it works. It's just that keepalived is better.
