Looks like some problem with rpm creation.
The problem appears to be that the RPM was created with the dumpcap program having some file capabilities set, and was
unpacked into an NFS-mounted directory, which means that the capability bits can't be set.
If the capability bits aren't set, either you'd have to run Wireshark/TShark as root, which would be an Extremely Bad
Idea (as doc/README.packaging says:
In versions up to and including 0.99.6, it was necessary to run
Wireshark with elevated privileges in order to be able to capture
traffic. With version 0.99.7, all function calls that require elevated
privileges have been moved out of the GUI to dumpcap.
WIRESHARK CONTAINS OVER TWO MILLION LINES OF SOURCE CODE. DO NOT RUN
THEM AS ROOT.
Warnings are displayed when Wireshark and TShark are run as root.
so don't do it), or you'd have to make dumpcap set-UID root (as doc/README.packaging says:
There are several configure-time options on non-Windows systems that
affect the privileges a normal user needs to capture traffic and list
--enable-setcap-install Install dumpcap with cap_net_admin and
cap_net_raw capabilities. Linux only.
--enable-setuid-install Install dumpcap setuid root.
--with-libcap If running as root, try to grab
CAP_NET_ADMIN and CAP_NET_RAW, then drop
privileges. Linux only.
--with-dumpcap-group=... Restricts dumpcap execution to the
--enable-setcap-install might produce an RPM that can't be properly installed over NFS, so you'd have to try
--disable-setcap-install and --enable-setuid-install; if you do --enable-setuid-install on Linux, you should probably
use --with-libcap, and possibly --with-dumpcap-group=, as well, picking a group to which the ability to run dumpcap,
and thus to do captures when not running as root, should be granted).
