RHEL 7, networkmangler - trying to set hostname via dhcp

[m***@5-cent.us]

I have yet to find a simple way to do this, that was easy without NM. I've
found scripts... but no simple configuration file, nor RH docs, to tell me
how to have this automatically happen in the "correct" way.

Clues for the poor?

Hi Mark,

I think what you’re saying is that you want your system’s name to be set from the DHCP server. Is that correct?

Check if /etc/hostname is present and has some value. If so…
cp /etc/hostname /etc/hostname-`date -I` && rm /etc/hostname

Restart networking/reboot and see if that works for you.

Cheers,
Harry

Yes, the dhcp server should hand it its name. And hostname only has, IIRC (I'm
at home now) localhost.localdomain.

Right, so follow the set of commands I sent along. That should get you set.
