Restart Network in Ubuntu Linux

In Ubuntu there was inbuilt command whose job is to network card reconfiguration. Lets see the syntax

jay@server:~$ sudo /etc/init.d/networking restart
****OutPut****
[sudo] password for jay:
 * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces                                                              
 * Reconfiguring network interfaces...                                                                                                                   ssh stop/waiting
ssh start/running, process 1818
                                                                         [ OK ]

This Ubuntu script will start and stop all network interface (NIC) at once.

Alternative

jay@server:~$ sudo ifconfig eth0 down
 (replace eth0 with your ethernet number)
wait for ethernet down.

jay@server:~$ sudo ifconfig eth0 up
[sudo] password for jay:
