The IPRoute2 package contains programs for basic and advanced IPV4-based networking.

接下来这两段来自Wikipedia:http://en.wikipedia.org/wiki/Iproute2
另外,更详细的一篇文档:IPROUTE2 Utility Suite Howto
===========================

iproute2 is a collection of utilities for controlling TCP and UDP IP networking and traffic control in Linux, in both IPv4 and IPv6 networks. It is currently maintained by Stephen Hemminger. The original author, Alexey Kuznetsov, was responsible for the QoS implementation in the Linux kernel.

iproute2 is intended to replace an entire suite of legacy Unix networking tools that were previously used for the tasks of configuring network interfaces, routing tables, and managing the ARP table. Tools replaceable by iproute2 include the ifconfig and route utilities, as well as the arp command and various commands related to creating IP tunnels. iproute2 unifies the syntax for these various commands, which evolved over many years of Unix development. The iproute2 syntax is much simpler and more consistent for all of the functions that it provides, and imitates the syntax of Cisco's IOS operating system.

======================

arpd
    Userspace ARP daemon, useful in really large networks, where the kernelspace ARP implementation is insufficient, or when setting up a honeypot
ip
    The main executable. It has several different functions:
        ip link <device> allows users to look at the state of devices and to make changes
        ip addr allows users to look at addresses and their properties, add new addresses, and delete old ones
        ip neighbor allows users to look at neighbor bindings and their properties, add new neighbor entries, and delete old ones
        ip rule allows users to look at the routing policies and change them
        ip route allows users to look at the routing table and change routing table rules
        ip tunnel allows users to look at the IP tunnels and their properties, and change them
        ip maddr allows users to look at the multicast addresses and their properties, and change them
        ip mroute allows users to set, change, or delete the multicast routing
        ip monitor allows users to continously monitor the state of devices, addresses and routes
routef
    A component of ip route. This is for flushing the routing tables
routel
    A component of ip route. This is for listing the routing tables



ifcfg
    A shell script wrapper for the ip command. Note that it requires the arping and rdisk programs from the iputils package found at http://www.skbuff.net/iputils/.
tc
    Traffic Controlling Executable; this is for Quality Of Service (QOS) and Class Of Service (COS) implementations
        tc qdisc allows users to setup the queueing discipline
        tc class allows users to setup classes based on the queuing discipline scheduling
        tc estimator allows users to estimate the network flow into a network
        tc filter allows users to setup the QOS/COS packet filtering
        tc policy allows users to setup the QOS/COS policies


lnstat
    Provides Linux network statistics. It is a generalized and more feature-complete replacement for the old rtstat program
ifstat
    Shows the interface statistics, including the amount of transmitted and received packets by interface
ctstat
    Connection status utility
nstat
    Shows network statistics
ss
    Similar to the netstat command; shows active connections
rtstat
    Route status utility
rtmon
    Route monitoring utility


rtacct
    Displays the contents of /proc/net/rt_acct
rtpr
    Converts the output of ip -o back into a readable form


genl

==================================================================================

The Iana-Etc package provides data for network services and protocols.

/etc/protocols
    Describes the various DARPA Internet protocols that are available from the TCP/IP subsystem
/etc/services
    Provides a mapping between friendly textual names for internet services, and their underlying assigned port numbers and protocol types
