I’ve got an issue w/ running a distributed query using the 
yara
 table. If I run a basic yara rule using the 
sigrule
 column in osqueryi I get the intened results. If I run the same query via Fleet as a distributed query I get no results. The below query identifies the test file as expected in osqueryi, but nothing at all is returned via Fleet.
Copy code
select * from yara where path like "/Users/scavanaugh/Desktop/%" and sigrule = 'rule hello_world {
strings:
$a = "Hello world"
condition: $a
}';
Fleet is version 3.3.0 In osqueryi paths are returned for files that have no match, in Fleet this doesn’t appear to be the case

Also, @sean.cavanaugh already confirmed he is not running osqueryi w/ root
z
Can you run osqueryd with 
--verbose --tls_dump
and verify that Fleet is sending the correct query? What user is osqueryd running as?
s
sure thing, need to knock out a few meeting but will report back shortly
z
Fleet just sends osquery the data and returns the results -- usually this kind of thing is due to some permissions issue or unexpected change in the osquery configuration. That said, Fleet 3.3.0 is pretty old and there could be some bug. Your research will help us understand which is going on.
s
for sure
we’re on osquery 4.9.0 if that helps, working on the goods for you

things ended up working … for an unknown reason
I wonder if killing osqueryd did something but that doesn’t seem logical

Are you running osqueryd directly via CLI now? Was it running via launchd previously? I wonder if there might be some different config?
s
ok now I’ve got less good news

it worked when I ran it like so:
Copy code
sudo /usr/local/bin/osqueryd --verbose \
--tls_dump \
--allow_unsafe \
--config_plugin=tls \
--config_refresh=900 \
--config_tls_refresh=900 \
--config_accelerated_refresh=300 \
--config_tls_endpoint=/api/v1/osquery/config \
--disable_distributed=false \
--disable_enrollment=false \
--disable_tables=shell_history \
--distributed_interval=10 \
--distributed_plugin=tls \
--distributed_tls_max_attempts=3 \
--distributed_tls_read_endpoint=/api/v1/osquery/distributed/read \
--distributed_tls_write_endpoint=/api/v1/osquery/distributed/write \
--enroll_secret_path=/var/osquery/kolide_secret \
--enroll_tls_endpoint=/api/v1/osquery/enroll \
--host_identifier=hostname \
--logger_min_status=1 \
--logger_plugin=tls \
--logger_snapshot_event_type=true \
--logger_tls_endpoint=/api/v1/osquery/log \
--logger_tls_period=10 \
--pack_delimiter=/ \
--tls_hostname=<server> \
--tls_server_certs=<cert> \
--enable_file_events=true
it stopped working I resumed via 
sudo osqueryctl start
(after killing osqueryd)

sigh
really good flag, we had issues w/ that and some other fun
z
You could verify with 
sudo osqueryi
followed by 
.connect
That should "connect" to the running osqueryd process and let you try the query there -- I suspect you'll get empty.
s
neat
didn’t know about 
.connect
z
It's pretty new 🙂 Very cool feature though https://twitter.com/fleetctl/status/1387376047516053508
s
supported on 4.9.0 with 3.3.0? I seem to be coming up short
Copy code
-> % sudo osqueryi
Password:
Using a virtual database. Need help, type '.help'
osquery> .connect
Error: unknown command or invalid arguments:  "connect". Enter ".help" for help
z
Can you 
select version from osquery_info
in that shell?
Ah looks like you need 
.connect /var/osquery/osquery.em
"unknown command or invalid arguments" is not a very helpful error message
s
sorry was getting some things actioned in our env. we rolled out FDA and yara is working as intended from Fleet. I really appreciate the support @zwass 🍻
