Short Descriptions
bridge Configures network bridges
ctstat Connection status utility
genl Generic netlink utility frontend
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/.]
ifstat Shows the interface statistics, including the amount of transmitted and received packets by interface
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 continuously monitor the state of devices, addresses and routes
lnstat Provides Linux network statistics; it is a generalized and more feature-complete replacement for the old
rtstat program
nstat Shows network statistics
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 rtacct Displays the contents of /proc/net/rt_acct
rtmon Route monitoring utility
rtpr Converts the output of ip -o back into a readable form
rtstat Route status utility
ss Similar to the netstat command; shows active connections
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
