eithernet device inactive at startup

[number3]

Whenever I boot up my machine and log in as any user (root included) my ethernet device starts off as being inactive. And I'm forced to manually activate in order to have access to the internet (System - Administration - network -> highlight the defice, click Activate).

I'm trying to get my ethernet device to be activated from startup.

When I try to edit the profile for the device the 'Activate device when computer starts' is already checked and 'Controlled by NetworkManager' is unchacked. Also 'Automatically obtain IP address settings with : dhcp' is checked. In any case if I wanted to change the options I couldn't because the 'ok' button is disabled so I cn't modify any profile settings for my ethernet device.

Can any on offer any assistance? As it's a major pain to manually activate my ethernet device every time I start up my machine.

I am guessing it is eth0. post contents of /etc/sysconfig/network-scripts/ifcfg-eth0
Is there any other network interfaces on this machine?
Might run the dmesg command to see if there is any errors listed during boot.

Also contents of the file /etc/modprobe.conf
And post only the protion of the following command related to the network card. /sbin/lspci -v

I actually have 2 ethernet devices. One has an ethernet cable connected (eth0) and the other does not (eth1).

I have ifcfg-eth0.bak and ifcfg-eth1.bak.

ifcfg-eth0.bak:
# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
HWADDR=00:40:f4:2e:ae:f0
TYPE=Ethernet

ifcfg-eth1.bak:
# nVidia Corporation MCP55 Ethernet
DEVICE=eth1
BOOTPROTO=dhcp
ONBOOT=yes
HWADDR=00:17:31:8f:a3:c3
TYPE=Ethernet

modprobe.conf:
alias scsi_hostadapter libata
alias scsi_hostadapter1 sata_nv
alias scsi_hostadapter2 pata_amd
alias snd-card-0 snd-emu10k1
options snd-card-0 index=0
options snd-emu10k1 index=0
alias snd-card-1 snd-hda-intel
options snd-card-1 index=1
options snd-hda-intel index=1
alias eth0 8139too
alias eth1 forcedeth


I should also note, that this problem came up recently. When I initially installed Fedora 8 I didn't have this problem. But I installed updates (software updater, just about everything that was listed as an updated) and since then I've been getting this issue..

[Brian1]

Both interfaces are set to start onboot and both are set as dhcp and when that happens they get an ip and also a gateway. I would change the line in eth1 to ONBOOT=no and reboot.

I made the changes suggested, however I got the same results I was getting previously.

I read this somewhere on these forums and it worked for me with the same issue.

Go to system/services. After typing in your root password, highlight "NetworkManager" and click stop, then uncheck the box. Next scroll down to "network", check the box and start the service. You ethernet device should start on boot now.

I tried those settings and I'm still having the same issue.

I'm not sure if this helps anyone but in System - Administration - Services - network it says

Configured devices:
lo
Currently active devices:
lo virbr0

What do you see under network configuration? I have 2 network cards installed but only using one at this time.

This is what I see except that upon a fresh start up device eth0 is set to Inactive.

I have this same problem. Worked well when first installed Fedora 8, then started up inactive on both NIC's after updates.
I am going to try a few of these ideas tomorrow then try removing the PCI NIC card. I had to add the second card to my HP a1230 when Fedora 6 would not recognize the onboard NIC. Is this a problem with 2 NIC's?

[The_Geek]

Go back to network configuration and double click on the interface you want to use. Once you configure it, make sure the box is checked to "activate device when computer starts".

[number3]

Did that and this is what comes up by default. What messes me up is the fact that after I enter in my root password I still don't have the 'OK' button enabled. It's disabled so no changes I make are committed.

[The_Geek]

May want to take a look at this thread. I also had an issue with "admin mode not working".

[number3]

I have tried logging in as root and editing my ethernet profiles and I'm still getting the disabled 'OK' button in addition to the ethernet device not being activated upon start up.

One thing that is similar is that like the user in that other thread I had a bunch of updates and after installing them all something seems to have one wrong.

Is there any other diagnostic I can check (maybe during startup) that may shed some light?

You're not alone I'm posting a new topic 'Upgrade Broke Network IF' which is related to this except I've got an RTL8169
