Thanks Oliver.
Any thoughts on why I can't get the SSHCollector script to trigger though
("(info) skip: driver or action not applicable"), ND2_LOG_PLUGINS=1 providing
no further clues.
While I potentially have a workaround now using that -p option, that's still
going to need work and is still < SSHCollector ( < SNMP::Info
ipNetToPhysicalTable). It must be something simple but I can't see it.
Jethro.

Hi Jethro,
Ah you're right the API wiki page has Perl syntax (not JSON) because the
mojolicious library will convert it. The netdisco-do man page is misleading.
It actually means to refer to the API spec itself which is here:
https://netdisco2-demo.herokuapp.com/swagger-ui/?url=/swagger.json#/Objects/put_api_v1_object_device__ip__arps
I'll see if we can make netdisco-do doc clearer.
By the way, glad to see -p option being used. In the next major version this is
changed to be "-e '@/path/to/file'" or you can pipe it in with "-e '@-'". Just
to make it a bit cleaner across different commands.
regards
oliver.

Hey,
I've tried it with and without the action:.
Adding env ND2_LOG_PLUGINS=1 provided no additional output here:

[35351] 2025-08-22 10:42:36 debug snmp reader cache warm: [ipaddress]
But I didn't know about that, so I will remember it in future thanks.
Failing progress here, I took a look at doing it out-of-band, and then using:
Submit arpnip results directly to Netdisco by putting the JSON data in a
file and using the "-p" option (see API web docs for data format
example):
~/bin/netdisco-do arpnip -d 192.0.2.1 -p /tmp/arp-table.json
Which also seems a more recent addition I'd not noticed before. But while the
API docs suggest the format for the JSON should be:
[
{ mac => "aa:bb:cc:dd:ee:ff", ip => "A.B.C.D" }
]
I had to write it such:
[
{ mac: "aa:bb:cc:dd:ee:ff", ip: "A.B.C.D" }
]
But it did work! So that's another interim workaround perhaps. Still icky.
J.

Your config looks fine at a first glance except for I have never seen
action: used in device_auth... just as a wild guess maybe try without it?
You can also try ND2_LOG_PLUGINS=1 as env var to get some more output
from plugin and worker selection, maybe that helps.
Cheers
