Hello,

I've installed Kismet from the latest package available in the Fedora 25 repo, version 2013.03.R1-7.fc24. The package installs fine but kismet_capture refuses to run, and I wondered if someone has advice?

The executable is installed setuid root:
-rwsr-x---. 1 root kismet 7304 Feb 4 2016 kismet_capture

And I'm executing kismet from an account 'kismet' which is in the kismet group:

[kismet@mini ~]$ groups
kismet

Yet I still get

FATAL: !!! CRITICAL ERROR !!! - Could not launch kismet_capture control binary,
due to permission errors. To run Kismet suid-root your user MUST BE IN
THE 'kismet' GROUP. Use the 'groups' command to show what groups your
user is in, and consult the Kismet README for more information. - Kismet
will not operate correctly.

The software seems to work fine if I run kismet as root and start kismet_capture from there, so this DOES seem to be a permissions problem, but what? Is it perhaps necessary to do some kind of SELinux reconfiguration?

[kismet@mini ~]$ ls -Z /usr/bin/kismet*
system_u:object_r:kismet_exec_t:s0 /usr/bin/kismet
system_u:object_r:bin_t:s0 /usr/bin/kismet_capture
system_u:object_r:bin_t:s0 /usr/bin/kismet_client
system_u:object_r:kismet_exec_t:s0 /usr/bin/kismet_drone
system_u:object_r:kismet_exec_t:s0 /usr/bin/kismet_server

Thanks for any pointers!
