- -------------------------------------------------------------------------- Trustix Secure Linux Security Advisory #2004-0015

Package name: tcpdump, libpcap Summary: New upstream Date: 2004-03-30 Affected versions: Trustix 1.5 2.0 2.1

- -------------------------------------------------------------------------- Package description: Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can capture and display the packet headers on a particular network interface or on all interfaces. Tcpdump can display all of the packet headers, or just the ones that match particular criteria.

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
