Fedora 12 networking eth0 and eth1

[varinder]

I am trying to setup linux box as router. What i am trying to do is


1. I am trying to setup NIC via network not NetworkManager
2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1
3. #Ifconfig shows my nic and ip
4. restart the service network .
5. #ifconfig shows nothing. NO NIC card

i dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)

I tried to configure the NIC with Network Manager

when ever i restart the network service i have no out put from ifconfig

i tried to configure the NIC with #setup command as well and select the dhcp option


I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/


Any idea Hint Please


Thanks

Sorry i forget to mention about hardware i just bought yesterday

AMD 3200

Disable the NetworkManager Service. (chkconfig NetworkManager off)
Use the system-config-network command to set up the network to NOT use NetworkManager, to start at system startup, include the hostname, the IP, the mask and the gateway address. Also include the DNS server address(es) on the DNS tab.

varinder , you can try this, what the above poster siad, if you get it working let me know. I have tried many times since Fedora 6, in which such a thing as a static IP was actually possible using only "Network" in system services. Never one time could I make Fedora boot up with my connection automatically configured. I have a cable modem, and have to use a dynamic DNS address. Wish I had a static one again.

If you must use synamically assigned addresses then you will have to setup dhcp to do this.

BTW to see all interfaces try : ifconfig -a or ip link

To see if Linux see your network cards
# lspci |grep Ethernet and # dmesg |grep eth

Could try to make you own ifcfg-ethX

DEVICE=ethX
BOOTPROTO=none
HWADDR=00:141:17:32:B5
IPADDR=192.168.X.XX
NETMASK=255.255.255.0
ONBOOT=yes

If you do not know what your netmask should be you can run # ipcalc -m 192.168.X.XX to get it.
easy way to get HWADDR is to # ifconfig ethX up
and also do
# chkconfig --level 35 network on

Neither of these commands is reliable. lspci lists all the pci connected devices, but not all will have a pci.ids string containing "Ethernet" Some may be "Network" or :Wireless" or others. Also if there is no pci.ids match there will be no string description at all.

Do
lcpci -nnk | less
and look for the devices and their listed drivers. If any have no driver *then* look for the dmesg

dmesg shown the kernel messages but again "eth" is not necessarily in there. you might see "wifi" or others.

I really really appreciate the help i got you from guys

I did it successfully, still one question in mind. Let me explain

I did the following things

#service NetworkManager stop
#chkconfig NetworkManager off

from gui i select System->Administration->Network

and did all things means.. On boot selected yes. Controlled by networkManager --no

and it works fine. and it made changes to /etc/sysconfig/network-scripts/ifcfg-eth0 automatically..


it works fine..

But my question/doubt in mind

I did it through gui.. the alternative is i can manually edit/put all the things in /etc/sysconfig/network-scripts/ifcfg-eth0 file.

But why it is not working when i tried the command #system-config-network

it gives me text based menu(same as with #setup command) to configure the network card. and this menu does not have option to 'activate the NIC at boot' (that was the reason for problem)

thanks
