Netbox Plugin: Error: ipaddr: the address has neither IPv6 nor IPv4 format

notscottsmith

xo-server 5.80.0
xo-web 5.84.0

Expected behavior:
VMs to synchronise with the configured netbox instance
Current behavior

Error in logs saying that an IP doesn't fit the format expected (sync works otherwise, this is just to do with the IPs).

xo-server | 2021-07-26T05:14:11.136Z xo:api WARN admin@admin.net | netbox.synchronize(...) [13s] =!> Error: ipaddr: the address has neither IPv6 nor IPv4 format

This error log isn't sufficient to be able to troubleshoot the problem it's complaining about. More information is needed to figure out where the problem lies.

Can a higher level of logging be enabled within XO? Has anyone else come across this? Am i able to run an individual VM for synchronisation or run it manually via CLI to try and debug the issue?

@vilhelm That's fixed: https://github.com/vatesfr/xen-orchestra/pull/6328. Thanks again for the report

And what have you entered in the netbox plugin text fields?

notscottsmith

@olivierlambert Configuration info that works successfully. As said, the plugin works to synchronise the VMs and their details across. This is just for the IPs, it seems.

olivierlambert

Okay so what are the IPs returned in your XO UI?

notscottsmith

@olivierlambert Every IP that is visible to XO (there might be one or two which can't be seen purely because the guest tools aren't working, but they're not malformed) is formatted correctly.

I've included a screen grab of part of it to show how XO is rendering it.

Is there a way I can run this manually via cli to see some more data or pick out an individual VM to see which one is causing the hiccup?

olivierlambert

Yes, you can use xe, eg xe vm-param-get param-name=networks uuid=<VM UUID>. This would return all IPs known by Xen tools.

notscottsmith

@olivierlambert Yes but that's not going to tell me what the netbox plugin is erroring on. That command returns data which looks correctly formatted with no issue but there is something somewhere in it which is causing a problem.

I meant is there a way for me to run the netbox plugin sync by hand in cli or VM by VM to see where the problem occurs.

Or, barring that, a way to increase the logging level so that I can see with more detail what uuid at least, it's failing on and debug from there.

olivierlambert

I'm not sure we can get more, it might be the way some IP are parsed. Pinging @pdonias

notscottsmith

@olivierlambert I did some digging and just added some extra logging to the script file and found the culprit:

2021-07-27T09:03:46.545Z xo:netbox INFO Parsing IP: 10.44.254.253 10.44.254.254

It's in interface that's listing two IPs together with a space between.

I've tried a couple of things to get it to ignore any like those that it finds but haven't been successful yet. You have already closed/fixed an issue I raised about this about a month ago so I'm not sure why I'm seeing it in this one, now. It's the 5.80 server.

olivierlambert

@pdonias does it sound to be the problem?

pdonias

@olivierlambert Most likely, yes. But it shouldn't be an issue anymore after this change (XO 5.60) so I don't understand why the error is still happening.

@notscottsmith Do you see those space-delimited IPs in the UI too?

notscottsmith

@pdonias Yea, it shows up like this:

pdonias

@notscottsmith Ok, could you run this inside XO's directory with the VM's host and its password:

./packages/xen-api/dist/cli.js --au <HOST> root <HOST ROOT PASSWORD>

It should start a CLI. And then run this with the VM's UUID:

> find({ uuid: '<VM UUID>' }).$guest_metrics.networks

notscottsmith

}

pdonias

@notscottsmith So apparently, the old protocol also adds x/ipv4/x fields with space-delimited IPs. That's what causing the issue, so we'll have to handle them too. Thanks!

notscottsmith

@pdonias

So I've dug into the issue and written a few workarounds which will tide me over until a fix comes out - appreciate your work on this.

I've added a few features in, too. The plugin now:

Allows the choice of whether IPv4, IPv6 or Both types of IPs are synchronised
Allows you to enter in tags which will deem a VM to be "ignored" if they have one of these tags
Allows you to enter in text which if the name label contains it, it will also be ignored (we have a use case where we have several VMs which are decommissioned but are kept in XCP for various reasons as well as our backup process which maintains a series of VMs with the prefix XCP-BACKUP, which we don't want kept in Netbox)
Allows you to configure the ID of the configured VRF in Netbox (if needed) that the particular IP ranges relate to
Synchronises the platform that the VM is running
Brings across all the tags and puts them into Netbox (this is for our monitoring solution, OpenNMS, which uses Netbox to generate its requisitions and categories to automate the provisioning process)

I will submit these changes back into the Git repo tomorrow when I'm back in the office and you can have a look and see what you want to use.

@notscottsmith @pdonias

any updates on this? Currently running into this error myself.

olivierlambert

Are you up to date? I think we fixed that already

theAeon

I think so? Unless my script isn't updating the plugins, which is totally possible.

edit: quick look at github says my plugins are fine

olivierlambert

Not the latest commit but I don't think it matters in your case. @pdonias any idea?
