I'm trying to exclude specific src_ip addresses from the results of a firewall query (example below). The query completes, however the src_ip addresses are not excluded and the following error is returned: [subsearch]: The lookup table 'dns_serves.csv' requires a .csv or KV store lookup definition.
Example:
index=firewall
| search NOT [|inputlookup dns_serves.csv | fields src_ip]
| table src_ip dest_ip signature
When running |inputlookup dns_servers.csv by itself the contents of the lookup are returned so I know the lookup is good. I've checked the lookup permissions, CSV encoding, and searches forum threads for a solution.
I had the same error this morning. I didn't have either the Lookup Table file or the Lookup definitions as global. Once I changed them both to global, the error went away.
Excluding the src_ip addresses is working now. I had a typo in my lookup name. The error is still present.
Are you saying it is working or there is an error? I'm assuming the typo was serves.csv vs servers.csv, but if there is still an error, can you say what the current problem?
