Registration failed! - Hostname invalid

[Nilesh Agarwalla]

Hello,

I recently switched my home network to use 4x OpenWRT-based Access Points.  I have an Ubiquiti EdgeRouter that is configured to assign static IPs via DHCP to the access points.  I also have DNSmasq enabled so that I can do local hostname lookups.

I cannot get auto-registration to work using the local DNS hostname but using the MAC address directly works.

E.g. my access point is named: ap_master.agarwalla.local and has a local IP: 10.0.1.5

I can successfully do an nslookup of ap_master.agarwalla.local from the OpenWisp server:

nilesh@OpenWisp:~$ nslookup ap_master.agarwalla.local

Server:         10.0.1.1

Address:        10.0.1.1#53

Name:   ap_master.agarwalla.local

Address: 10.0.1.5

 

I installed and setup OpenWisp and also configured /etc/config/openwisp on the OpenWRT router:

config controller 'http'

option url 'https://openwisp.agarwalla.local'

option verify_ssl '0'

option uuid ''

option key ''

option shared_secret 'XXXX'

Auto-registration fails as follows:

root@ap_master:~# logread -f

Thu Jan 14 14:45:03 2021 daemon.info openwisp: Registering device...

Thu Jan 14 14:45:03 2021 daemon.err openwisp: Registration failed! {     "name": [         "Must be either a valid hostname or mac address."     ] }

Using the MAC address directly DOES work, though....but then I can't change the hostname via the web interface:

Any thoughts on how to get this all to work with the local DNS hostname?

Tnx!

Dear Nitesh,

At the moment the validation rule does not allow dots, I am not sure this was intentional.

Using only "ap_master" as the hostname will work. Does this prevent you from deploying the configuration you need?

Best regards

Federico

Hi Federico,

The regex doesn’t seem to allow underscore ‘_’, so ‘ap_master’ didn’t work either, but ‘master’ did.

Sounds like a bug, I opened a bug report here: https://github.com/openwisp/openwisp-controller/issues/367

Thanks!
