Dotaz: DHCP server + DHCRELAY

[Michal]

Zdravim. Uz delsi dobu se snazim rozchodit DHCP server na jednom stroji a DHCRELAY na druhem stroji, ktery bude predavat dotaz prvnimu.

DHCP server
na eth0 net 10.10.10.2
na eth1 lokal 192.168.1.1

v /etc/default/dhcp3-server

INTERFACES="eth1"

v /etc/dhcp3/dhcpd.conf

authoritative;
deny unknown-clients;
default-lease-time 86400;
max-lease-time 86400;          
option domain-name-servers 192.168.10.2;

subnet 192.168.10.0 netmask 255.255.255.0 {
range 192.168.10.2 192.168.10.254;
option routers 192.168.10.1;
option broadcast-address 192.168.10.1;

host TEST {hardware ethernet 00:E0:4C:BD:97:C9; fixed-address 192.168.10.2;}

}

sit 192.168.10.0/24 je routovana na stroj 192.168.1.2, kde potrebuji rozchodit dhcrelay.

DHCRELAY
/etc/default/dhcp-relay

INTERFACES="eth1"
DHCP_SERVERS="192.168.1.1"
OPTIONS=""

Problem nastava uz pri spusteni dhcpserveru

Starting DHCP server: dhcpd3 failed to start - check syslog for diagnostics.

V logu je hlaska

No subnet declaration for eth1 (192.168.1.1).

Da se spustit DHCP server, aby nekontroloval to co ma na sitovkach ??

Mrkni se do /etc/init.d/dhcpd nebo jak se to jmenuje v tve distribuci a nastav si pro ktere sitovky to bude, vim, ze v debianu byla chyba, ze INTERFACES si ten skript nebral, protoze tam byl nekde bug, alespon v te me verzi. Takze pokud mate treba ten 192.168.1.10 na eth1 192.168.1.1 na eth0 tak dhcpd -q eth1, jinak napravit skript.

Pouzivam debian. Nevis nahodou co presne si v tom souboru /etc/init.d/dhcp3-server menil. Zmenil jsem

start-stop-daemon --start --quiet --pidfile $DHCPDPID \
                        --exec /usr/sbin/dhcpd3 -- -q $INTERFACES

na

start-stop-daemon --start --quiet --pidfile $DHCPDPID \
                        --exec /usr/sbin/dhcpd3 -- -q eth1

to nepomohlo. Porad to same. DHCP ma potiz v tom ze ma nastavene rozdelovani IP 192.168.10.X. A na zadne sitovce tento rozsah nema nahozeny.
