Install / Usage Problem Tumbleweed #1125

I am using
6.19.12-1-default
"openSUSE Tumbleweed"
libpcap1 Version : 1.10.6-1.3

I downloaded the rpm and attempted to install the Sniffnet_LinuxRPM_x86_64.rpm with "discover" which noted the download was not complete.
I again downloaded the rpm (17,3 MiB) and tried to install the Sniffnet_LinuxRPM_x86_64.rpm with YAST-Software, which also reported a problem but offered an ignore button, and the installation succeeded.
I was able to start the application Sniffnet, upon choosing the network adapter and pressing start I received the error:
"libpcap error: Attempt to create packet socket failed - CAP_NET_RAW may be required"
I concluded that I didn't have the needed privileges so I ran:
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/sniffnet
Which resulted in the error "sudo: setcap: not found"
My last ditch to obtain the needed privileges was to start from the command line with:

sudo /usr/bin/sniffnet
