Ubuntu: What does these logs means? (DHCPREQUEST)



Question:

I'm using Ubuntu 14.04 LTS as my OS. For safety purposes, I'm always checking the logs to see any strange thing. Today, I have found something that (probably) never happened to me:

Jun 11 23:33:59 nori-hidamari dhclient: DHCPREQUEST of 192.168.0.3 on wlan0 to 192.168.0.1 port 67 (xid=0x21f83c60)  Jun 11 23:33:59 nori-hidamari dhclient: DHCPACK of 192.168.0.3 from 192.168.0.1  Jun 11 23:33:59 nori-hidamari dhclient: bound to 192.168.0.3 -- renewal in 3175 seconds.  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info> (wlan0): DHCPv4 state changed reboot -> renew  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   address 192.168.0.3  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   prefix 24 (255.255.255.0)  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   gateway 192.168.0.1  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   nameserver '189.7.80.15'  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   nameserver '189.7.80.16'  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   nameserver '201.6.4.116'  Jun 11 23:33:59 nori-hidamari NetworkManager[979]: <info>   domain name 'domain.name'  Jun 11 23:33:59 nori-hidamari dbus[541]: [system] Activating service name='org.freedesktop.nm_dispatcher' (using servicehelper)  Jun 11 23:33:59 nori-hidamari dbus[541]: [system] Successfully activated service 'org.freedesktop.nm_dispatcher'  

Can someone tell me what's happened here? Please note that I saw this on syslog

Thank you guys for helping me.


Solution:1

This person asked pretty much the same question on Unix & Linux stack exchange.

Here is the start of the answer, probably more efficient for you to click over to the link.

First 3 lines are messages from dhclient which:

sent a DHCP request to the router  received DHCP lease  set up the interface
