Scan network not working

Hi, on a /16 subnet trying the UI feature Network → DNS and DHCP → Scan network

I get this error:

Cannot scan network

Something went wrong

AxiosError: Request failed with status code 504

command: echo ‘{“device”:“br-lan”}’ | /usr/libexec/rpcd/ns.scan call scan

But using arp-scan from the command line works fine:

root@user:~# arp-scan  -I br-lan --localnet

Thank you for reporting!

Please follow the instructions on the dialog and past it here :wink:

Sorry, forgot to paste it above:

root@user:~# echo ‘{“device”:“br-lan”}’ | /usr/libexec/rpcd/ns.scan call scan

Traceback (most recent call last):
  File "/usr/libexec/rpcd/ns.scan", line 64, in <module>
    args = json.loads(sys.stdin.read())

The above JSON is not valid due the bad hypens.

Try this:

echo '{"device":"br-lan"}' | /usr/libexec/rpcd/ns.scan call scan

takes a long time:

Still not working after upgrade to 8.7.1 on 3 different firewalls, even on a clean install.

I think it is just a timeout…

7

Could you time the echo ‘{“device”:“br-lan”}’ | /usr/libexec/rpcd/ns.scan call scan command? Probably a timeout, but I can adjust that

8

Already there in the post above: arp-scan alone took 263 seconds (with only 17 responds).

On public WiFi networks you have to use networks bigger then /24.

Or having 100 employees, everybody with a notebook, tablet and mobile phone…

PS: This should be asynchronous.

9

Sure, but I need the overhead of our script that parses the output, since we’re talking about many hosts, this could time out on the API or the UI, since I feel they have different timeouts.

Probably need to apply a custom timeout for some of the calls.

Not planned for now, but this surely is the right approach, I agree.

I have just change the quotations marks from ‘ to '

time echo '{"device":"br-lan"}' | /usr/libexec/rpcd/ns.scan call scan
