Brakuje co najmniej

Code: Select all

option subnet-mask 255.255.255.0;

/etc/conf.d/dhcpd:

Code: Select all

# If you wish to run dhcpd in a chroot, uncomment the following line
# DHCPD_CHROOT="/chroot/dhcp"

# Specify a configuration file - the default is /etc/dhcp/dhcpd.conf
# DHCPD_CONF="/etc/dhcp/dhcpd.conf"

DHCPD_IFACE="eth1"

# Insert any other dhcpd options - see the man page for a full list.
# DHCPD_OPTS=""

Praktycznie niepotrzebne. Demon DHCP zacznie działać na interfejsie, który odpowiada adresom IP z /etc/dhcp/dhcpd.conf.
PS. Opcja przydatna (wymagana) dla IPv6.

uruchom recznie server

Code: Select all

dhcpd -f eth1 

o ile dobrze pamietam
i do tego

Code: Select all

 tcpdump -i eth1

i warto:

Code: Select all

 /etc/init.d/iptables stop

rozumiem ze pomiedzy eth1 a kompami ktorym przydzielasz IP jest tylko zwykly switch

rozumiem ze pomiedzy eth1 a kompami ktorym przydzielasz IP jest tylko zwykly switch

raczej router przerobiony na switch,

Brakuje conajmniej:

Code: Select all

option subnet-mask 255.255.255.0;

teraz działa,
