[b]Setting Hostname by DHCP server info[/b]

[roberto dias]

My DHCP server sets a fixed IP number and hostname for each MAC number.
How can I set my hostname getting this info ?

I can´t find anything how

"dhcpinfo -i eth0 hostname"
"dhcpcd -H"

How can i do this with pump

[adamepo]

sudo pump -i eth0

that is all
(look at /etc/resolv.conf)
