Thread: Setting up Internet Connection (Redhat)

  1. #1
    i just installed Redhat 9 on my new computer, i always wanted to try the linux and now i have the chance but i cannot go any furture until my internet connection problem is sorted!!!!!

    i have two computers connected through belkin adsl modem router built-in. linux machine is connected through the ethernet! NIC on linux machine is known as 3Com 3c51 (i dont know if thats right),nickname is eth0 and also device is eth0 i have the option to change that any number i want, well up to 7... IRQ: is unkown (i dont know if thats right ethier). its not activiting, everytime i try to activate, it gives me msg that "cannot activate network 3th0" "3c501 device eth0 does not seem to be present, delaying initialization"


    please let me know what the problem is or if i need to amend somethin!

    well it's sort of a guess but i think you need to find and install a driver for it.
    use windows to search the net for linux drivers for that network card.

    how do i find out what driver i need in linux i.e. commands or setting, i mean there has to be something which tells me about the NIC!!!! although i have motherboard disk which contains the NIC drivers!!!

    oh yeah! thanks for replying

    I also have a 3Com nic and it works. You may not have support for your nic in your kernel, or there may be a module for it and its not being loaded.

    Put in this command:
    Code:
    dmesg | less
    That will bring up all the messages you saw at boot, just a little easier to read this way.

    i mean there has to be something which tells me about the NIC!!!!
    Enter this into a terminal:

    lspci

    it should output something like this:

    Code:

    I know this probably doesn't help you that much, sorry.

    thx for replying!

    i tried that command lspci but it didnt work for me and i also tried these methods still no luck

    The list that follows provides an overview of the most important commands. Of course, a lot more commands are available for examining the innards of a Linux system.

    lspci
    lspci lists all the components on the PCI bus. The option -vv returns a detailed list, while -vn returns only the device IDs. Please mind to execute lspci as root.

    grep
    grep is the most commonly used command for searching the contents of files on Unix/Linux. Important: grep is case-sensitive. You can disable case-sensitivity with -i.

    For example:

    Without -i:

    linux:~ # lspci | grep controller
    00:06.0 SCSI storage controller: Adaptec AHA-2940U2/W / 7890
    00:09.0 Ethernet controller: Digital Equipment Corporation DECchip 21140 [FasterNet] (rev 22)
    00:0a.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 06)
    01:00.0 VGA compatible controller: nVidia Corporation Riva TnT 128 [NV04] (rev 04)
    and with -i. The USB controller is also included in the list.

    linux:~ # lspci | grep -i controller
    00:04.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01)
    00:06.0 SCSI storage controller: Adaptec AHA-2940U2/W / 7890
    00:09.0 Ethernet controller: Digital Equipment Corporation DECchip 21140 [FasterNet] (rev 22)
    00:0a.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 06)
    01:00.0 VGA compatible controller: nVidia Corporation Riva TnT 128 [NV04] (rev 04)
    The pipe character | passes the output of the first command to the second, thus saving you a step. Otherwise, the output from lspci would have to be routed to a file (with >), which would then have to be retrieved by grep:

    linux:~ # lspci > file
    linux:~ # grep controller file
    i think if the lspci command works then i might be able to find if linux is detecting NIC, i know its not gona be much help, but i need to know this at this stage!

    LSA, a noob question

    when u said

    Put in this command:
    u meant Terminal by that?

    mEtho, try this

    /sbin/lspci

    or this

    /usr/sbin/lspci

    (In a terminal)

    The directories /sbin and /usr/sbin may not be in your $PATH.

    u meant Terminal by that?
    Yes

    Good luck

    had a bit of a look around the red hat hardware compatibility list and its not on it.
    so i looked for some drivers and the first google hit was this

    http://gul.ime.usp.br/Docs/docs/HOWT...-HOWTO-11.html

    the thing that caught my attention was this.

    3Com 3C501 - ``avoid like the plague''
    might be worth paying out 10 for a new nic that is defiently supported.

    /sbin/lspci
    above command worked, thx very much! now i see the ethernet controller in it, what does it mean, do i need drivers for it or do i need to configure it and if yes, how?

    00:04:0 ethernet controller: nVidia corporation nForce2 ethernet controller
    that is the ethernet controller of my comp! so if it shows in linux, does that mean that its ok!!!

    @4play

    thx for help!!!

    i will buy a new nic card but the strange problem is that linux sees my nic card atm, so i am hoping it might work,, if it doesnt work then i am gona have to work!!! i would be more then happy if u guys could help me in any way is u can!!!

    looks to me like it thinks your 3com ethernet controller is made by nvidia a graphics card maker.

    the linux drivers for the card are now incorparated into the kernel. might be worth either grabbing a more up to date linux distro with the 2.6 kernel or compiling your own kernel.

    I would check which kernel you have by using

    $ uname -r

    then grab the latest version in that branch. from www.kernel.org my guess would be

    http://www.kernel.org/pub/linux/kern...tch-2.4.29.bz2

    then follow the guide at http://www.osnews.com/story.php?news_id=443

    edit: sorry the above link is just the patch the full kernel is

    http://www.kernel.org/pub/linux/kern...2.4.29.tar.bz2

    the kernel i am using atm is 2.4.20-8 (redhat 9)

    do u think, redhat is worth using it cos lots of the user are menting mandroke or whatever its call for a new user and alos its easy to use, i dont know how anybody can define, all linux looks same to me... same commands etc!!! how about if i give it a go anyway, mandroke is on three which will take me about one night to download but that is not the main concern, i am really pissed off now, reading about linux etc, i just want this internet to work now!!!!

    let me know what u think... i can either update the kernel by following the guide u provided (i hope its easy for a newbie) or i can download Mandrake 10 or 10.1, i dont know if 10.1 is a beta version or full!!!!
