Hi all.

Sorry of my English.

I have problem after reboot my SL 6.1

Linux server.localdomain 2.6.32-131.12.1.el6.x86_64 #1 SMP Tue Aug 23 11:13:45 CDT 2011 x86_64 x86_64 x86_64 GNU/Linux

dhcpd not run

my configuration is very simple

CODE

cat /etc/dhcp/dhcpd.conf
ddns-update-style interim;
subnet 192.168.254.0 netmask 255.255.255.0 {
range 192.168.254.20 192.168.254.50;
default-lease-time 600;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.254.255;
option routers 192.168.254.254;
option domain-name-servers 8.8.8.8, 217.15.134.65, 217.15.135.68;

This is problem only on vlan interface eth0.2 ( vlan 802.1q)
if you run on a physical interface eth0 that will be all right

After reinstalling dhcpd problem persists

Help me please !
