Network Problem Fedora Core 1

[belwaffle]

Hi!

I am new to Linux but I used to run RH9 on my Acer Tavelmate 800 laptop and the network was working fine. My computer has a broadcom 440x integrated network card. The card is detected perfectly and I set up the parameters for my network (IP adrs, netmask, gateway and dns) but for some reason it doesn't work, the laptop doesn't get onto the network. When pinging the gateway I receive the ICMP message Host Unreachable, doing the same from another computer works perfectly... any ideas?

Thanks! :(

For general info and education, you can start with the ifconfig man page. Enter this at the command line.

man ifconfig

As another general piece of advice, do all the research you can on your own. You may be able to answer your own question or you may learn enough to ask a more meaningful question. Try not to drop vague and ignorant questions in forums such as this. People will be less likely to help you. man pages are a great source of info and can lead to other man pages that you need. There are also a wealth of FAQ's online for everything Linux. A google search is your best friend. Now to the answer to your question.

First I would check to make sure that the interface is even active. You can do that by running ifconfig like so.

su -
*enter root password*
ifconfig

You should see an entry for the local loopback device, lo. You should also see an entry for your ethernet device, probably eth0. If you don't then your problem is the simple fact the the device isn't active. Determining why is the next hill to climb. If that is the case, while still logged in as root, run the following.

service network restart

You will either see everything come up as it should, or you will see some error trying to bring up eth0, or you won't see eth0 try to activate at all. Whatever the case, that should help you find which tree to bark up next.

Restrict you debug to the ip address, netmask and gateway parameters. DNS is surely not the case now. Double-check your cable too. 90% your netmask is wrong or your cable is bad. 255.255.255.0 is the firts try.

HTH,

Have patience, Wrayman. No one is born with this knowledge. I think what belwaffle said was pretty complete; he told us his hardware, his problem, and tests he used to determine it. How was he to know ifconfig?

There's an easier way, too. As root, type:

redhat-config-network

and that's a grahical tool that's a bit easier to use at first. Make sure your setting are correct. If you don't see an "eth0" (your first/only Ethernet card), then you know it wasn't detected.

If it's there, make sure it's correctly identified.

If there, and identified, make sure it's "active."

This sounds a lot like my problem too. Your the current computer a laptop too? I have narrowed my problem to a issue with "susmend" when my laptop computer (compaq armada7400) running FC1 is place in the susmend mode the network is dropped and left with a "Network Unreachable" message when pinging even my LAN. The only way I have found to stop it from doing this is to take the battery out, no AC power, and short the computer battery leads as to discharge the computers remaning power. I then get as I reboot the machine a hibernation error at bootup with options (of which only one works). If I do not get this error, the computer does not let me use the network.

When I right click on the suppend battery in the "tray", and try to suppend the computer I get a error message saying suppend was not set up correctly (How to set it up is a question of mine? It might fix it.) But the only option I see with apm that may be useful is:

apm -s

to suspend.

I have just check the version they are:

# apm -v
APM BIOS 1.2 (kernel driver 1.16)
AC off-line, battery status high: 36% (1:06)
# apm -V
apm version 3.0.2

I hope this help both of us.

i had the destination host unreachble problem..with all other linux..i can ping my lan..but with FC4...it has the destination host unreachable..why?
