You might want to double-check that you have libpcap and libpcap-devel
(the packet capture library) installed, and not libcap and libcap-devel
(the Linux/POSIX capabilities library). It's pretty easy to get tripped
up by this.
Opps! Spelling would help here, wouldn't it? I yummed up libpcap, et.
al. and away it went.
BTW, do any popular Linux distributions support file system capabilities
out of the box yet? It'd be nice to be able to grant CAP_NET_RAW to
Wireshark/TShark instead of having to run as root. Capabilities have
been in the kernel for a few years now, after all...
I'm not sure on the answer to this one.
Thanks for your help.
