ifconfig network interface (such as eth0 eth1, etc.) up | down
Two routers route modification
Route - [no]
-n: Do not use a communication protocol or a host name, directly ip / port number
-ee display more detailed information
Modify the command
route add / del [-net | -host] [network or host name] netmask [mask] [gw | dev]
add / del: add or remove
parameter:
-net represents a route followed by the network
-Host rear contact portion to be connected to a single host router
netmask subnet mask
gw: access gateway behind value ip
Dev specify which network card is connected back to go out with a network interface
E.g
route add default gw 192.168.1.2 --- increase the default router, after setting up, / etc / init.d / network restart
route add/del -net 192.168.100.0 netmask 255.255.255.0 dev eth0
