option domain-name "z202.example.com"; option domain-name-servers 192.168.202.1; option domain-search "linuxhotel.de";
Ist eine Möglichkeit einen laufenden DHCP-Server ohne Neustart zu steuern ( leases, etc. ).
dhcpd.conf
:
domain-name "main.domain" domain-search "additional.domain"
With 3.1.0, if the domain-search option is set, then the search directive is set to this. If the domain-name option is set, this is prepended to the list of domains in the domain-search option.

z.B. nach Got POOLREQ, answering negatively! Peer may be out of leases or database inconsistent
