Fedora Update Notification
FEDORA-2019-eaa681d33e
2019-10-27 01:08:27.202809
——————————————————————————–

Name : libpcap
Product : Fedora 30
Version : 1.9.1
Release : 1.fc30
URL : http://www.tcpdump.org
Summary : A system-independent interface for user-level packet capture
Description :
Libpcap provides a portable framework for low-level network
monitoring. Libpcap can provide network statistics collection,
security monitoring and network debugging. Since almost every system
vendor provides a different interface for packet capture, the libpcap
authors created this system-independent API to ease in porting and to
alleviate the need for several system-dependent packet capture modules
in each application.

Install libpcap if you need to do low-level network traffic monitoring
on your network.
