also check your DNS entries ...... cat /etc/resolv.conf
make sure you see something similar to this:
nameserver 123.123.123.123
nameserver 223.223.223.223
(your nameservers must match a valid DNS server from your ISP)
If not change them or enter them in the same format like in this example and reboot your machine.
well i have tried the basic connectivety check ...as i am a linux newbie so could not make much of the commands. the results are as follows
ifconfig -a

<b> netstat -rn </b>
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 lo
HOW CAN I change the destination & gateway IP ... its should not be 169.254.0.0 .... in my windows i use manually assigned ip some what like 10.x.x.x
and as the network work perfectly in windows.. so i donot think so there is some problem with the cable or switch ... and i donot know how to logonto switch/router .......
i didnot have any router ...its just a small home network of 4-5 PCs
AND I think i got to change the DNS server entry and make it same as in my windows ... i will try that .....
As I said, above ... that is the reason why you can't access internet.
You must use your favorite editor and put the following entries into /etc/resolv.conf ... and then reboot
nameserver 123.123.123.123
(where 123.123.123.123 is the nameserver given to you by your ISP - call them if you are not sure)
You can have multiple nameservers in the resolv.conf file, one per line
ex:
nameserver 123.123.123.123
nameserver 222.222.222.222
nameserver 111.111.111.111
seems to me the output from ifconfig and netstat show that your only your loopback interface has an IP and you have no default gateway at all. Assuming your subnet is 10.0.0.0 try this:
ifconfig eth0 10.0.0.1
then look at the output from ifconfig, it should be different.
then assign a default gateway. The output from ipconfig /all on one of the windows boxes should give you the default gateway to use,
let assume that this is 10.0.0.254
then just do:
route add default gw 10.0.0.254
then look into adding entries in your /etc/resolv.conf.
Also, you say you don't have a router, but you must be connecting to the internet somehow, please elaborate on your exact setup, like how are the windows boxes connecting to the network and I will try to offer more help.
ifconfig eth0 10.0.0.1 ...command do not give me any ouput
i have configured the network ethernet manually with the manual ip for my pc and gateway and dns ... the ones i used in windows ......using the network device IDE provided in the system tools
now the ifconfig command gives the desired ips .....
but i tried to ping the other computer on the network ...but failed ...the pc could ping itself at the manually assigned address.
There is no problem with the cable ... the newtork work fine in windows .... i think there is some problem with the drivers ... i used the AMD Athlon processor and marvell yukon 88e8053 PCI-E ethernet controller and nvidia built in etherenet card ..
how could i ensure that the drivers are properly loaded...
My network is a simple 4-5 Pc home network .... One act as a gateway and is connected to the internet (through optic fibre) the rest of teh Pc gets the internet from teh gateway
Perhaps in this case it would be easier to advise using the GUI interface provided in Fedora?
Go to the 'System Settings -> Network' (gnome - is probably similar under KDE) dialog. You'll need the root password. You should get something like this:
http://www.l3.net.nz/image
Select 'eth0' (your ethernet adapter), and hit 'Edit'.
Select 'Statically set IP addresses', and enter an address (eg: 10.0.0.3) - make the first 3 numbers the same as the first 3 numbers on your Windows machines, but the last number different to any of the Windows machines (so if the Windows machines have 10.0.0.2 and 10.0.0.3 you could use 10.0.0.4). Use the same subnet mask as you've used on your Windows machines. And set the 'Default gateway address' to the IP address of the Windows machine that's sharing the internet.
Hit 'OK', then go to the 'DNS' tab, and enter your DNS server(s) - the same ones as your Windows PC's use.
Now try pinging other PC's on the network, see if there's any change.

Check basic connectivity first:
1) Do you have an IP configured on the proper interface? (ifconfig -a)
2) Is your default route set (netstat -rn)
3) Is the cable connecting the server to the switch good (look for send/receive errors, ifconfig -a)
4) is the switch port good (logonto switch/router, depends on type)
5) is the switch port turned up (logonto switch/router, depends on type)
Give those a try
