Nessus "Discovery" not working via nessrest
I'm trying to do a simple ping scan (plugin 10180 - https://www.tenable.com/plugins/index.php?view=single&id=10180). However it doesn't work - I do
% ./ness_rest --plugins 10180 --targets '192.168.218.6/31' --insecure
and according to the web UI no hosts are found. If I try to run the same type of scan from the web UI it does find both 192.168.218.6 and 192.168.218.7.
I've also noticed that "Port Scanners" don't show up as a plugin family if I try to generate an "Advanced Scan" and pick the plugins manually. Moreover, they don't show up in the REST API request to the /plugins/families resource:
% http --verify=no -v GET 'https://<server-ip>:8834/plugins/families' "X-ApiKeys:${NESSUS_X_APIKEYS}"
Is this a known or deliberate limitation or is there something I'm doing wrong?
(NOTE: other plugins seem to work!)
