Splunk for Asset Discovery: How to troubleshoot why I am getting no results and if the script is running on Ubuntu 14.04

[chrislibby]

I'm trying to get Splunk for Asset Discovery working. The scripts work fine from the command line, and Splunk is running as root so it should work. However, there are no results and I cannot tell if the script is running. Can anyone help point me in the right direction?

Hi chrislibby,

like in the docs of the app written you have to change line 111 of nmap.sh to be like this:

 nmap $nargs $target #2>/dev/null

to get nmap errors. Also check for errors related to the script in splunkd.log

 index=_internal nmap.sh

cheers, MuS

That lead me to these errors, which adding "unset LD_LIBRARY_PATH" fixed.
