Dobrý začátek by mohl být třeba takový, že napíšete, co to znamená "NEFACHA"…

[Petr Šobáň]

Přesně tak.

Není spuštěn dhcpd, firewall to blokuje atd.....

Rekapitulace
v dhcd.conf mam nastaveno :

option domain-name "firma.cz";
option routers 192.168.100.254;
option domain-name-servers 195.146.100.5;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.100.255;
default-lease-time 3600;
max-lease-time 7200;

subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.2 192.168.100.200;
}

etc/default/dhcp je pouze radek Interfaces = "eth0"

pokud zapnu dhcpd vypise me
No subnet declaration for eth1 (192.168.1.30).
Please write a subnet declaration in your dhcpd.conf file for the
network segment to which interface eth1 is attached.
exiting.

[Ruža Becelin]

Tohle:

etc/default/dhcp

je doufám jenom překlep?

[Martin]

neni to preklep.... taklhel to tam mam je neco spatne ?

[Ruža Becelin]

Má to být:

/etc/default/dhcp3-server

[Ruža Becelin]

Aha, teď se dívám - vy máte DHCP server verze 2 ?? Jak starou verzi debiana máte?

[Martin]

Mam posledni verzi Debiana - Sarge

[Ruža Becelin]

To já taky:

dhcpd3 --version
isc-dhcpd-V3.0.1

[Ruža Becelin]

Jinak doporučuju

apt-get install dhcp3-server

a zkusit to znovu nastavit...

[Martin]

DHCP3 nainstalovano, stary DHCP je pryc
Nyni se zda byt jiz vse OK i kdyz nevim co znamena ten posledni radek

[Ruža Becelin]

Co je v logu za chybu?
Máš nastavené, na kterém rozhraní má DHCP server poslouchat?
Co to je za distribuci, atd., atd...

Z toho mála toho moc nevyvěštíme...
