Re: [qubes-users] Anonymizing hostname
Thanks for your code. I will try to use it with /dev/urandom to generate a random hostname... I will post my findings Dominique On Tuesday, February 28, 2017 at 11:24:31 AM UTC-5, steve.coleman wrote: > On 02/27/2017 03:48 PM, Dominique St-Pierre Boucher wrote: > > Hello, > > > > I have setup the mac address change for qubes 3.2 with debian 9 as my > > sys-net. > > > > I am trying to figure out a way to randomize the hostname that is sent to > > the DHCP server.

Since I use an enriched f-24-minimal I opted for macchanger .. it works well for my ethernet, but won't touch the wireless mac address. Bizarre! I first searched a typo, but can't find one. May this be a firmware problem (iwlwifi for Intel 7260)? How to log the problem ??

I'm not quite sure why you need to hide you hostname on your local DHCP network. Is the purpose so that you "feel" more hidden? Anyone running p0f on your local network will guess your OS regardless of your IP/MAC/hostname randomization, and people outside your domain won't have your MAC or DHCP hostname, just your IP unless you/IT publish your name through DNS to the outside.

[qubes-users] Anonymizing hostname
Hello, I have setup the mac address change for qubes 3.2 with debian 9 as my sys-net. I am trying to figure out a way to randomize the hostname that is sent to the DHCP server. This is in an effort to minimize the risk of os identification. Can you help? Can you think of anything else to protect the id of the OS?
