How to change ip for ubuntu host in java

Question

There is an ubuntu host with multiple ips. I want to make periodical change its ips in my java application. But I do not know how to do this. Does any one know about this?

Just exec whatever command you would use to do it in a shell. — user207421, Mar 09 '14 at 23:02

You could use your Java application to rewrite /etc/sysconfig/network-scripts/ifcfg-ethX (or wherever your network scripts are) and set the IP address you want. Then you would need to ask your Java application to run a bash script, reloading either the device or the whole network.

I could paste a couple of examples here but you will find loads on internet. :)

Thanks EJP and Desorder, I think it is not necessary to reboot the server after resetting ip by your way. Is it right? – PhilipSong Mar 11 '14 at 00:40
@PhilipSong Nah man, you don't need to reboot the whole server, you only need to reload the network. On Centos/Red Hat, you would run `#service network restart` and that is it. :) – Desorder Mar 12 '14 at 00:25
