Hi,
when I setup Observium for the first time, I used a local only DNS setup. In the meantime, we created a corporate wide DNS setup for our Lab. Old devices are still available, but obviously show up with their old hostname. Is there an easy way to change the hostname of a device?

Hi Guys,
I am looking for the best way to update DNS on our network.
We are a WISP with around 10k devices.
Currently we do most of our monitoring with software which does not care about DNS and works via IP.
I have begun playing with Observium and really like.
In order to have the freedom to add devices to our Observium instance at will, we will have to level up our DNS game massively.
What solutions do people currently use to register hardware with DNS at the time of deployment? Is it possible for a DNS server to discover hardware (based on IP ranges we give it) and query for hostnames then add them to the database?
Thanks Guys
Alasdair
If the hostnames that you would use don't need to be super descriptive or match the actual device's hostname, you could easily just generate a list of hosts file entries for the entire subnet(s) that contain the IP as part of the hostname.
e.g:
127.0.0.1 localhost 192.168.1.1 192-168-1-1.domain.tld 192.168.1.2 192-168-1-2.domain.tld etc...
If you would prefer to have the actual device hostnames used, I think the best course of action would be to write a script that can scan the ranges, connect to and query the hostname from responding IPs, and dump it into a hosts file on your observium server. Depending on how many different types of devices you have, this may or may not be practical, since you would presumably need to create a slightly different subroutine/function for each type.
If you actually want the devices to have a real DNS record, you may be able to use a similar script to push dynamic updates to your DNS server, but it really depends on your specific setup.
I am not aware of any existing, "generic" server-side subnet scanner + dynamic DNS updater, but a script such as the above would be a "non-generic", and is certainly feasible.
To me, since your current monitoring solution doesn't care about hostnames, and you (seemingly) don't have any need for DNS records outside of fulfilling Observium's requirement, I think the first option makes the most sense, by far.

Hi Alasdair,
If you have about 10k devices, do you have some existing database/spreadsheet/etc of ips and device names?
You could mangle this and dump it into a dns zone, making sure it keep it updated.

I guess it may be useful for the enterprise/paid version to also allow raw IP addressed to be added with the ‘addhost’ script; or even entire ranges; even if there is absolutely no (reverse) DNS at all.
Right now you have to fiddle quite a bit to work around the ‘no such hostname’.

While you are at that - it is a bit of a ‘pro’ feature - but being able to accept a ‘-‘ instead of a hostname & pipe a file in - or something similar - is most useful as well.
Especially if it is omnipotent - so will *NOT* replicate the entry if a name is sent there more than once (even if that identifier has changed IP address in the meantime).

So it is useful to be able to run; say a nightly cron-job - or as part of some puppet script - a ‘add_device’ of all your devices; without much ado. I.e. not check if they are already there (and deal with removal differently/explicitly).
At the point of the add_device you want those identifies to be what they are; even if they perhaps resolve to a different IP address at that point of time.

We already accept a file as input. Use /dev/stdin if you really want to pipe it in from stdin ;-)

Yeah, we have a custom interactive database that we use to track, provision, reclaim IP addresses on the network.
I am ideally looking to ensure that this is not a manual task that someone has to update on a semi-regular basis.
I think from the responces I have received on a number of forums that what I want to achieve is not currently available on any DNS management platforms.
Ill continue to play with observium in our DC and see if it warrents the extra work for us to use it globally.
Thanks for all the input. You guys are legends.

If you have an existing host -> ip database, what you want to do is moderately trivial using BIND. Just generate a zone file for your devices periodically and tell BIND to refresh it.
