    hetworking--- DHCP

    I am new to Linux and I was wondering if you could help me out with a problem. I installed 8.0 on a duel boot computer. As the Linux o/s is booting up I am receiving the following error "Determining IP information eth0 failed: no link present-- check cable". I know the cable is OK because it works fine on W2K O/S. I am using DHCP for my IP address settings but when I look under my system settings and click on network it states status as inactive. Any clues on what I have to do? I would like to access the internet and e-mail but I can't because of this problem. I would appreciate any help you can give me.

    Check the firewall - turn it off to start with.

    What is the DHCP server? Your ISP or another Computer?

    What DHCP server program is running on it? (if you know)

    Have you tried a static IP Address to see if that will work first? (if you can)

    Can you ping 127.0.0.1 ? (localhost)

    Does ifconfig show eth0? (Im guessing probably not but worth checking)

    what does /etc/sysconfig/network-scripts/ifcfg-eth0 look like? (could be a configuration problem?)

    These might help to resolve all this a bit more

    Its better to regret something you have done than to regret something you havent done :P

    frisky,

    What I did to solve my problem is I went into network config menu and editted the profile to statically set IP addresses and manually setup the ip address, subnet mask and default gateway address, instead of using dhcp. I then rebooted my machine and as it booted up i didn't get any errors. I went back and used ifconfig -a and lsmod. All of the output looked like it suppose to:

    inet addr:192.168.0.# bcast:192.168.0.# mask:255.255.255.0
    rx bytes;11506 (11.2 kb) tx bytes:1200 (1 kb)

    lsmod output: 3c59x size=30640 used=1

    and I can ping local hostlocal host 127.0.0.1 but i still couldn't use internet or e-mail. I am not really familiar with using Mozilla. Do I have to do something in order to se the internet? Any suggestions? Thanks for all your help.

    Ok what does your network look like first?

    Internet----Another Box or router ??-------Your linux Box ???

    If so make sure the ip address and gateway is goin to work with the "Another Box or router"

    I am not really familiar with using Mozilla. Do I have to do something in order to se the internet?
    Nope, just make sure the default gateway is correct.

    Also DNS - check your DNS settings (my guess is - it is this)
    you have to put your ISP's DNS address in /etc/resolve.conf

    like :
    nameserver xxx.xxx.xxx.xxx <---- whatever the ip address is
    nameserver xxx.xxx.xxx.xxx

    Lastly - u didnt mention the state of your firewall.

    Good luck
