ahoj, nejprve se omlouvam, ze se ptam na neco, co uz se tu resilo zrejme hodnekrat, ale zatim jsem tady, ani nikde jinde nic, co by mi pomohlo, nenasel (a to ze jsem dneska poradne googloval, skoro cely den). bohuzel jsem v koncich... takze k samotnemu problemu:

na routeru (kde se snazim rozjet dhcpd) mam Slackware current, kernel: 2.6.15.3, dhcpd V3.0.3, dve sitova rozhrani eth0 (pro inet), eth1 (pro lan). eth1 je spojeno primo krizenym kabelem s druhym pocitacem (kde bezi bredevsim windows 98) - zadne jine pocitace v siti nejsou, coz vas asi povede k otazce "proc tedy to dhcp?" ... no proste jen doplnuji vedomosti :]

pokus o "graficke" znazorneni topologie:

ISP <-----> eth0 : router (linux) : eth1 <-----> klient (win98)

muj /etc/dhcpd.conf:

# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#
#DHCPD_INTERFACE="eth1";
authoritative;
ddns-update-style none;
use-host-decl-names true;
option subnet-mask 255.255.255.0;

subnet 192.168.1.0 netmask 255.255.255.0 {
        default-lease-time 86400;
        max-lease-time 604800;
        #range dynamic-bootp 192.168.1.11 192.168.1.25;
        #range 192.168.1.11 192.168.1.25; 
        option domain-name "paranormal.org";
        option domain-name-servers 213.46.172.36, 213.46.172.37;
        #option ip-forwarding false;
        option routers 192.168.1.10;
        option broadcast-address 192.168.1.255;
        }
        host Amadeus {
                hardware ethernet 00:C0:26:32:9A:C8;
                fixed-address 192.168.1.20;
                }

... ty zakomentovane veci jsou pozustatky ruznych experimentu... zkousel jsem toho vic :o)

kdyz spustim dhcpd tak je _snad_ vsechno OK:

root@p4t0k:~# dhcpd eth1

nejake info o eth1 na routeru:

root@p4t0k:~# ifconfig eth1       
eth1      Link encap:Ethernet  HWaddr 00:01:02:10:88:B6  
          inet addr:192.168.1.10  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::201:2ff:fe10:88b6/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:15 errors:0 dropped:0 overruns:0 frame:0
          TX packets:18 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:8850 (8.6 Kb)  TX bytes:1188 (1.1 Kb)
          Interrupt:10 Base address:0xf80 

a posledni vec... trosku jsem si zasniffoval na eth1 a tady je hlavicka packetu od klientskyho pocitace (je na nem zrovna linux, ale predpokladam ze s widlema by to bylo asi stejne):

---[ UDP ]-----------------------------------------------------------
0.0.0.0:68(bootpc) -> 255.255.255.255:67(bootps)
Version: 4       Total Lenght: 576      TTL: 64
Packet Number: 3

---[ UDP Data ]------------------------------------------------------

Klient zasila requesty, ale server neodpovida (ano, dhcpd urcite bezi!)

... tak to je asi vsechno, ted uz jen otazka -> Co delam spatne?
