[08:10] <lordievader> Good morning
[08:15] <xue> hi
[08:15] <xue> goodbye
[13:57] <utkarsh2102> that was fast :P
[14:33] <octav1a> Hey, I have some machines I set up on my university network with one hostname, and now I desire to change that hostname. I did the tutorial for hostnamectl, --pretty, and changing the /etc/hosts. However, over the local network I still can not log into these machines using the new hostname. Is it a matter of waiting some time or do I need to do something else?
[14:34] <oerheks> 2 places, edit /etc/hosts and /etc/hostname
[14:34] <oerheks> hostnamectl is just for this session, it does not get stored
[14:36] <patdk-lap> how do you mean login using the new hostname?
[14:36] <patdk-lap> all those things are local machine only, and don't affect other systems
[14:36] <patdk-lap> you likely need to update dns
[14:36] <patdk-lap> unless you are using mdns, in that case I personally dunno what is advertizing mdns
[14:36] <patdk-lap> did you reboot after your changes?
[14:38] <octav1a> I don't know how the university DNS works, but when I installed the OS's to begin with, the name i chose was somehow automatically broadcast, and other computers could see it. 
[14:38] <octav1a> I just want to repeat whatever was triggered during the initial installation process. 
[14:39] <octav1a> Is there a way to send a packet: "hey, my dns changed" ?
[14:39] <oerheks> just edit /etc/hostname too, and you should be fine
[14:39] <oerheks> nothing to do with dns/mdns..
[14:39] <octav1a> oerheks: it is, because I want this name o work when connecting via ssh  from other computers on the network. 
[14:40] <octav1a> Changing hat file /etc/hostname seems to have been done automatically by hostnamectl
[14:41] <patdk-lap> well, there are only two ways dns changes
[14:41] <patdk-lap> mdns, that is done with broadcasts from your own system
[14:41] <patdk-lap> or via dhcp dns updates
[14:42] <patdk-lap> I would think a reboot would *fix* either of those
[14:42] <oerheks> octav1a, if the name matches, there should be no issue..
[14:42] <octav1a> patdk-lap: can these services be restarted / updated without a reboot?
[14:42] <patdk-lap> yes
[14:43] <patdk-lap> how? dunno what does mdns, so I dunno
[14:43] <patdk-lap> dhcp you have to restart networking on that interface
[14:48] <octav1a> sudo dhclient -r && sudo dhclient 
[14:48] <octav1a> seems to be the solution.
