Не стартует dhcp3-server при нескольких VLAN

[muhlik]

Здравствуйте, уважаемые господа!

И так что имеем:

# uname -a
Linux srv-gw 2.6.31-19-server #56-Ubuntu SMP Thu Jan 28 03:40:48 UTC 2010 x86_64 GNU/Linux

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 9.10
Release:        9.10
Codename:       karmic

# apt-cache showpkg dhcp3-server
Package: dhcp3-server
Versions:
3.1.2-1ubuntu7.1

Данный сервер работает в качестве шлюза, на нем настроены 6 VLAN поверх одной сетевухи

# The primary network interface
auto eth0
iface eth0 inet manual

#INET1
auto vlan0002
iface vlan0002 inet static
        address x.x.x.x
        netmask 255.255.255.252
        vlan_raw_device eth0

#INET2
auto vlan0006
iface vlan0006 inet static
        address y.y.y.y
        netmask 255.255.255.252
        vlan_raw_device eth0

#LAN
auto vlan0003
iface vlan0003 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        vlan_raw_device eth0

#DMZ
auto vlan0004
iface vlan0004 inet static
        address z.z.z.z
        netmask 255.255.255.240
        vlan_raw_device eth0

#WI-FI
auto vlan0005
iface vlan0005 inet static
        address 172.16.0.1
        netmask 255.255.255.0
        vlan_raw_device eth0

#VoIP
auto vlan0007
iface vlan0007 inet static
        address 172.16.4.1
        netmask 255.255.255.0
        vlan_raw_device eth0

от DHCP требуется раздача IP для #WI-FI

# cat /etc/dhcp3/dhcpd.conf
ddns-update-style none;
option domain-name "company.ru";
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 172.16.0.0 netmask 255.255.255.0 {
  range 172.16.0.10 172.16.0.254;
  option routers 172.16.0.1;
  option domain-name-servers 172.16.0.1;
  default-lease-time 7200;
  max-lease-time 86400;
}

Итак перегружаем сервер и видим в логах:

Т.е. dhcp3-server увидел только первый VLAN для которого у него нет конфигурации и сказал: Not configured to listen on any interfaces!

Теперь логинимся (сервак уже загружен и все интерфейсы поднялись) и делаем:

# /etc/init.d/dhcp3-server restart

теперь в логах:

Т.е. теперь уже поругался на все интерфейсы кроме того который сконфигурирован.
Какой вывод? При старте системы dhcp3 не дожидается пока поднимутся все интерфейсы и соотвественно нужного ему не находит и не стартует... Есть ли какие-нибудь мысли как заставить его ждать пока все интерфейсы поднимутся?

[Mam(O)n]

Вот тут щас набросал скрипт, который будет ждать поднятия всех интерфейсов, перечисленных в /etc/network/interfaces как auto:

Код: [Выделить]

#!/bin/bash
for iface in $(/bin/cat /etc/network/interfaces | /bin/grep -e ^auto | /bin/sed s/^auto//); do
while ! /sbin/ifconfig $iface > /dev/null 2>&1; do
[ "$wi" != "$iface" ] && /bin/echo -n "Waiting for $iface..." && wi=$iface
/bin/sleep 1
done
[ "$wi" = "$iface" ] && /bin/echo "done."
done

можешь его попробовать добавить в скрипт, пинающий dhcpd
