Vsetko islo OK, az kym som sa nezacal hrat s wifi kartou v mojom ibm notebooku u nas vo firme.
Ide o to, ze dhcp demon sice ziska zpravne udaje z dhcp servera, ale nevie ich predat systemu tak, aby ich system vyuzival pre svoje pripojenie k sieti, ale stale vyuziva len to co som nastavil rucne pred tym, ako som zapol dhcp v yaste.
----
napriklad dam if up eth0 a dhcpd zisti udaje z dhcpservera, ale v subore /etc/sysconfig/eth0xxxx.conf (myslim) je vsetko tak, ako som dal rucne.
----
Naviac v yaste je zaskrtavatko, ze ziskat dns z dhcp a to by sa mali txt policka vypnut, aby sa nedala vlozit rucne hodnota. ono to tak ide, dam ok, zavriem okno, otvorim okno a vsetko je tak, aby sa dali hodnoty zapisovat rucne a samozrejme z dhcp to nic neziskava.
Co je v souboru /etc/sysconfig/network_ifcfg-eth-id-xx:xx:xx:xx:xx:xx?
V podstate ak dam v yaste DHCP, musim rucne napisat ipcky DNS a Gateway, lebo inak mi to nepojde!
Ked v yaste nastavim IP napevno je tam toto:
BOOTPROTO='static'
MTU=''
NAME='IBM PRO/1000 MT Mobile Connection'
REMOTE_IPADDR=''
STARTMODE='auto'
UNIQUE='rBUF.tqwo9I3YIvF'
USERCONTROL='no'
_nm_name='bus-pci-0000:02:01.0'
BROADCAST='9.138.217.255'
IPADDR='9.138.217.43'
NETMASK='255.255.255.0'
NETWORK='9.138.217.0'
--------------------------------
Ked v yaste dam DHCP tak toto:
BOOTPROTO='dhcp'
MTU=''
NAME='IBM PRO/1000 MT Mobile Connection'
REMOTE_IPADDR=''
STARTMODE='auto'
UNIQUE='rBUF.tqwo9I3YIvF'
USERCONTROL='no'
_nm_name='bus-pci-0000:02:01.0'
BROADCAST='9.138.217.255'
IPADDR='9.138.217.43'
NETMASK='255.255.255.0'
NETWORK='9.138.217.0'
A co se stane, když zadáte příkaz rcnetwork restart? Jak přesně jste zjistil, že dhcp server zašle údaje, ale klient je nepřijme. Prostě napište, co všechno už jste podnikl, ať tyhle kroky rovnou přeskočíme :-)
Pokud máte aktivní firewall, musíte si do povolených služeb přidat DHCP klient.

Teda je to takto.
1. Dam v yaste ze DHCP a DNS ze ma zistovat z DHCP a Gateway nedam ziadnu hodnotu, nech si zisti z dhcp.
2. OK, zavriem yast
3. skusim internet cez browser a nejde
4. dam ifconfig

5. dam rcnetwork restart:
IBMT41Tomas:/home/tomas # rcnetwork restart

6. dam ifstatus eth0:
IBMT41Tomas:/home/tomas # ifstatus eth0

---------------------------------------------------------------
7. teraz v yaste necham vsetko ako doteraz len dam ipcky DNS 9.64.163.21 a 9.64.162.21 a gateway 9.138.217.1 a teraz uz to ide OK, ale takto dhcp nema fungovat!
a co je rozdiel to je po vypise ifstatus eth0:
ifstatus eth0
eth0 device: Intel Corporation 82540EP Gigabit Ethernet Controller (Mobile) (rev 03)
eth0 configuration: eth-id-00:0d:60:fc:02:7f

Co se stane, když zadáte:
?
1. ifconfig ath0 down
nic nevypise iba vidim ako zhasne LED, ktora indikuje zapnute wifi
2. zadam vsetky 3 prikazy a ono to ide!!!!!!
IBMT41Tomas:/home/tomas # ifconfig ath0 down
IBMT41Tomas:/home/tomas # ifdown-dhcp eth0
IBMT41Tomas:/home/tomas # ifup-dhcp eth0
Starting DHCP Client Daemon on eth0... . IP/Netmask: 9.138.217.43 / 255.255.255.0
3. Problem je vo wifi? Aky subor mam editovat, aby to behalo aj po reboote?
