Just installed Fedora Core 4 to dual boot with WindowsXP on my Dell Inspiron 9300, but I can't get the internet to work.

ifconfig eth0 output=>

eth0 Link encap:Ethernet HWaddr 00:12:3F:D7:56:6B

eth0 is a Broadcom Corporation BCM4401-BO 100Base-TX

I have a router setup that does DHCP. I also have a wireless card I want to get working, but we'll take this one step at a time.

I will check back frequently, so if you nee anymore info, just ask.

I am extremely new to Linux, so please make any instructions as simple and clear as possible. Thanks in advance for any help!

Hi

Go to the command line, type, (make sure you're root)
dhclient

See if you can obtain any IP address.

I entered dhclient, then ran ifconfig eth0 again, and everything looks the same, should anything have changed here?

run netconfig eth0 command
or system-config-network or redhat-config-network or setup command.
try this out

Satoo.

Tried those configureation tools, but I still coul not even ping my router.

Anyone else have any suggestions?

check your netmask,your default gateway or your DNS server entery

set a static ip, under the network domain, then see whether you can ping the router.

if can't you might have to troubleshoot down to the physical level.

I have exactly the same problem. Onboard lan card trying co to connect though a netgear firewall/router/modem. Works all ok within win2k trying to get it to run with fedora 4 cant ping the router eth0 and lo all return pings. Just trying to install correct drivers for the ULi eth0 card. To see if that fixes it

#ifconfig

I have installed fedora 4 and i want it is to be a firewall. For that i installed two ethernet cards and configured. If I ping a pc connected through eth0,it is working , but i ping a pc connected thr eth1,it is not pinging it tells destination host unreachable.I changed with new eth card . Even after i am not able to connect pcs through eth1. if I give ifconfig, it tells everything OK. what may be the prblem. pls reply.

have you implemented Masquarading with you iptables firewall
Is the computer connected to eth1 connected directly or with a switch or hub?
If its directly connected, you need a dedicated "Crossover" cable

I tried with Crossover cable as well as switch.both it doesn't work. I came to know it is not hard ware problem. I studied after everything fine then only we can implement masquarading and etc..But basic should work. Here i am not able to communicate via eth1, what may be other prob

Please reply

Try these steps,
1. Try disabling your eth0, then get a IP from eth1.
2. Ping the Router or any other workstations on the Subnet
3. print your route here if it doesnt work.

Sir,

Thank u for answering .I tried ur 2 steps but I am not able to connect pcs connected thrgh eth1.

I gave the command route , the output is as follows

[root@fedora ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
192.168.0.0 * 255.255.0.0 U 0 0 0 eth0
192.168.0.0 * 255.255.0.0 U 0 0 0 eth1
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0


my configuration is

eth0
ip - 192.168.0.38
mask - 255.255.0.0
gateway -192.168.1.1

eth1
ip - 192.168.0.39
mask - 255.255.0.0

In the Linux machine i can browse . So i want this linux pc as firwall,
thatswhy I installed two eth cards. Basically if i ping the machines connected via eth1 should work, but is not ,so i can not move further,

Please reply

In the same above question what is the use of command " route" Please explain
