[linux] dhcp server s vlan

[Rudolf Kollar]

zdravim.

Mam L3 switch HP PC 3500, ktory nema vlastny dhcp. Chcel by som spravit
jeden externy ktory by vedel robit s vlanami. Len niekde robim chybu.

Na switchi mam okrem ineho:

v kazdej vlane: ip helper-address x.x.x.x
a pre vsetky vlany
dhcp-relay option 82 append ip

teraz dhcp3 server

je virtualizovany /proxmox - openVZ/. Dhcp3 server bezi na ubuntu 8.04
server.

/etc/dhcpd3/dhcpd.conf

class "303" {
  match if binary-to-ascii(10, 8, ".", option agent.remote-id) =
"x.x.x.x /ipcka gw vlany/";
}
subnet x.x.x.x netmask 255.255.255.192 {
  pool{
     range x.x.x.10 x.x.x.60;
     allow members of "303";
  }
  option routers x.x.x.x;
  option broadcast-address x.x.x.x;
  option domain-name x.x.x.x;
  option domain-name-servers x.x.x.x;
  option domain-name-servers x.x.x.x;
}

/etc/default/dhcp-server

INTERFACES="venet0 venet0:0"

Vysledkom je ze klient pripojeny priamo na switchy chce ip-cku, server v
logoch ani nepipne ale cez tcpdump vidim ze nieco od klienta a switcha
prislo.

10:11:05.253165 IP x.x.x.x.bootpc /ip-cka gw vlany/>
dhcp3-server.bootps: BOOTP/DHCP, Request from 00:0a:e4:c4:81:d3 (oui
Unknown), length 318


Nevie ma niekto nakopnut ako dalej resp. kde robim chybu. Dakujem vsetkym.
