Description

Expected Behavior

passive command should work without sudo:

nohup find3-cli-scanner -i wlan1 -device xxxxxxx -family yyyyyy-server http://192.168.1.111:8005 -scantime 10 -bluetooth -forever -passive -no-modify

however returns errors:

2018-07-16 18:25:56 [ERROR] utils.go RunCommand:40 exit status 1: btmgmt find
2018-07-16 18:25:56 [ERROR] utils.go RunCommand:40 exit status 1: service bluetooth restart

if I run the command with sudo, with latest tshark version I'd need to remove hardcoded root protection (recompile?)

Contributor guide

Research direction
Investigate how to grant the necessary capabilities (e.g., CAP NET RAW, CAP NET ADMIN) or use setuid to allow the scanner to run without sudo. Check the specific error messages and system utilities (btmgmt, tshark) for required privileges.
