Dotaz: LTSP - tftp server na jine IP/subnetu nez router

[Zdeněk Štěpánek]

Zdravim

Mam dotaz ohledne LTSP. Ve vsech ukazkovych konfiguracich jsem ansel ze LTSP a tim i TFTP server je zaroven router subentu a tudiz se jeho IP bere z DHCP optiony routers. Jenze ja chci mit LTSP server na uplne jienm subnetu, nebo pripadne na stejnem subnetu ale ne na routeru. Specifikovat IP adresu v DHCP optionu nejde, vysledek je "192.168.1.1:192.168.5.5://kernel.."

V konfiguraci etherbootu na rom-o-matic je optiona DEFAULT_BOOTFILE. jenze me se nechce po zmene IPcka LTSP serveru obchazet stanice, to je nerealizovatelne.

Nevite nekdo co s tim?

Diky, Zdenek

Ahoj,

mě spolehlivě funguje tahle konfigurace dhcpd:
(dhcp,tftp a root jsou fyzicky různé stroje)

/etc/dhcpd.conf :


subnet 192.168.1.0 netmask 255.255.255.0 {
authoritative;
range 192.168.1.60 192.168.1.199;
default-lease-time 86400;
max-lease-time 172800;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers 192.168.1.10;
option netbios-name-servers 192.168.1.4,192.168.1.3;
option netbios-node-type 0x2;
option domain-name         "praha";         
option root-path             "192.168.1.11:/opt/ltsp/i386";
option log-servers       192.168.1.11;


host diskless1 {
hardware ethernet    00:07:e9:09:82:e7;
fixed-address        192.168.1.53;
next-server       192.168.1.12;
if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
            filename "/ethboot/eb-5.2.4-e1000.zpxe";
            } else if substring (option vendor-class-identifier, 0, 9) = "Etherboot" {
            filename "/ltspboot/vmlinuz-2.4.24-ltsp-1";
            option vendor-encapsulated-options 3c:09:45:74:68:65:72:62:6f:6f:74:ff;}
option host-name "diskless1";
}

host diskless2 {
hardware ethernet    00:07:e9:09:83:32;
fixed-address        192.168.1.54;
next-server       192.168.1.12;
if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
            filename "/ethboot/eb-5.2.4-e1000.zpxe";
            } else if substring (option vendor-class-identifier, 0, 9) = "Etherboot" {
            filename "/ltspboot/vmlinuz-2.4.24-ltsp-1";
            option vendor-encapsulated-options 3c:09:45:74:68:65:72:62:6f:6f:74:ff;}
option host-name "diskless2";
