Zdravim. Popis problemu:

Mam FC1, DHCPD v rozsahu 192.168.0.10 - 192.168.0.100

Kdyz pripojim nove PC s WIN do site a nastavim DHCP, prideli adresu 192.168.1.x. kdyz ale v prikazovem radku na tomto stroji napisu ipconfig /release a ipconfig /renew, prideli se spravna IP z daneho rozsahu. rozhodne na siti neni jiny stroj, kde bezi DHCPD

nevi nekdo?

Ukaž celý konfigurák dhcpd.conf a coby klienta pusť linux, na něm
dhclient -d
a napiš výsledek.

[Kamorek]

Sakra, jako klienta tu nemam zadny linux.

dhcpd.conf:

ddns-update-style none;
    subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.51 192.168.0.99;
    option domain-name "linuxicf";
    default-lease-time 7200;
    max-lease-time 86400;
    option routers 192.168.0.50;
    option domain-name-servers 192.168.0.50;
    option subnet-mask 255.255.255.0;
    option broadcast-address 192.168.0.255;
}


host kama {
    hardware ethernet 00:00:w2:fg:gg:hh;
    fixed-address 192.168.0.36;
    }
host dddd {
    hardware ethernet 00:ju:f5:hy:12:gt;
    fixed-address 192.168.0.132;
}

Windowsy chtějí dostat 192.168.1.175, server jim jí odmítne přidělit, ale oni jí stejně použijí. To na straně serveru nevyřešíš .

Jinak MAC adresa 00:ju:f5:hy:12:gt je fakt zajímavá .

[Kamorek]

) jojo, prece tam nebudu davat ostrou MAC )

Chces tedy rici, ze chovani DHCP je OK ?

[jm]

Nechybi ti tam radka?

authoritative;

[Michal Čihař]

To tam sice chybí, ale to nijak nezabrání Windowsům žádat o tu jinou adresu

[jm]

Ne, to nezabrani, ale mohlo by to zabranit tomu, aby si tu adresu pridelily samy...

[Michal Čihař]

Chování serveru je OK, chování Windows ne . Ale s tím ti neporadím.
