Netvrdim, ze som dokonaly, a ze nic neprehliadnem.
Skuste to ale vysvetlit grepu

man dhcpd | grep dev
<nic>

man dhcpd.conf | grep dev
<nic>

man dhcpd | grep eth
   hardware ethernet 08:00:2b:4c:59:23;
   look something like this:
   hardware ethernet 08:00:2b:4c:59:23;

man dhcpd.conf | grep eth
    Parameter statements either say how to do something (e.g.,
    how long a lease to offer), whether to do something (e.g.,
    a department  with  a  single  physical  ethernet  network
    may be necessary to run two 8-bit subnets on the same eth-
    A typical dhcpd.conf file will look something like this:
    two ethernet interfaces), both addresses are  supplied  to
    example, there should be something like:
      host ncd1 { hardware ethernet 0:c0:c3:49:2b:57; }
      host ncd4 { hardware ethernet 0:c0:c3:80:fc:32; }
      host ncd8 { hardware ethernet 0:c0:c3:22:46:81; }
      host ncd2 { hardware ethernet 0:c0:c3:88:2d:81; }
      host ncd3 { hardware ethernet 0:c0:c3:00:14:11; }
      host ncd1 { hardware ethernet 0:c0:c3:11:90:23; }
      host ncd4 { hardware ethernet 0:c0:c3:91:a7:8; }
      host ncd8 { hardware ethernet 0:c0:c3:cc:a:8f; }
    information to tell whether or not an  IP  address  is  on
    described.   The subnet number, together with the netmask,
    are sufficient to determine whether any given  IP  address
    The  uunnkknnoowwnn--cclliieennttss flag is used to
tell dhcpd whether or
    The bboooottpp flag is used to tell dhcpd  whether  or  not  to
    The bboooottiinngg flag is used to tell dhcpd whether or  not  to
    whether or not to look up the domain name corresponding to
      hardware ethernet 08:00:2b:4c:29:32;
      hardware ethernet 08:00:2b:4c:29:32;

Nic proti Vam osobne nemam, ale skor nez niekoho obvinite
z porusovania Meta-FAQ skuste RTFM. Vyzeta to tak, ze na
rozdiel od Vas som ho cital.

Pripadnu dalsiu diskusiu na tema "Porusovanie Meta FAQ"
smerujte do talk na linux.cz

Som zvyknuty pustat tieto sluzby cez
service dhcpd start

Viem kde mam hldat patricny script, aj kde mam spravit
napravu, ale neviem ako. man v tomto pripade nepomohol.

Cakal som, ze bude "iba" na eth0. Chcel vsetko.
man viz vyssie.

Zeby toto: ?
   option nis-domain		"domain.org";
   option domain-name		"domain.org";
   option domain-name-servers	192.168.1.1;

Uz som to nasiel /* a nemusel som ani citat man :-) */
Len som ten dhcpd.conf.sample na prvy raz zle pochopil
/* a v tom vam ziadny FM nepomoze */
Zadal som IP adresu toho routera a nie DNS. Pretoze tam
DNS nebezi, tak poziadavka skoncila v /dev/null
