 |
|
Once, again, hello to all!
After recompiling my 2.4 kernel, I have lost net access. All was in good shape before recompiling, so I believe the hardware to be in good shape.
The dmesg output is unchanged from when the network was running, but I now see the following when I run lshw : | Code: | *-network DISABLED

I'm very much a noob with this, and I'm lost without the network working. 
Any help would be very much appreciated!
Thanks, in advance...

cgmd,
The module for your network card is probably not being loaded.
Post your lspci output so we can tell you what it is.
If you know, modprobe it.

For what it's worth I get the same thing for my ethernet card (eth0). I'm connected to my home wireless through a Prism2-based card (eth1). I get this from lshw: | Code: | *-network DISABLED

cgmd,
try to emeger the intel gigabit card
if that dont work, you can set it from the kernel
Devices => network device => Ethernet gigabit => intel gigabit
Hope that help
-------------
edit:
Just reread your post, if you dont have the network then dont do the "emerge". Just compile it into the kernel. The default kernel doesnt incl the giggabit driver. Or u should try genkernel instead. |

cgmd,
Does running | Code: | | /etc/init.d/net.eth0 restart |
produce errors or does it work now ?

NeddySeagoon, thanks , again, for your interest...
As you inquired: | Code: | bash-2.05b# /etc/init.d/net.eth0 restart
* Unmounting network filesystems... [ ok ]
* Stopping ntpd... [ ok ]
* Stopping sshd... [ ok ]
* Bringing eth0 down... [ ok ]
* Bringing eth0 up via DHCP... [ !! ]
|
It appears to fail with DHCP...
I hope this sheds some light on things!
Thanks...

Also, by way of information, I had a functioning network before recompiling the kernel. I had tried to get information as to the cause of the problem | Quote: | | changing the 'User address space size' from 2GB to 3GB |

I am very hopeful to get this working, so I can further my learning experience and complete my gentoo transition. 
Thanks, again, for your help!

cgmd,
Your post shows that eth0 exists but has not been assiged an IP address. This shows that the kernel module is present, so it follows that your /etc/init.d/net file is not correct or the network startup script is not being run.
Lets assume that your /etc/init.d/net is correct. Running | Code: | | /etc/init.d/net.eth0 restsrt |
will start eth0.
If not, it points you an error in net.eth0.
To fix that we need to know if you use dhcp or static addressing.
If you have doen a careless etc-update, its very easy to put net.eth0 back to its defualt, which suits dhcp.

Thank you, NeddySeagoon and dellaxim
I ran your request, NeddySeagoon, with the following results: | Code: | bash-2.05b# /etc/init.d/net.eth0 restart
* Unmounting network filesystems... [ ok ]
* Stopping ntpd... [ ok ]
* Stopping sshd... [ ok ]
* Bringing eth0 down... [ ok ]
* Bringing eth0 up via DHCP... [ !! ] |
I reconfigured the kernel with my old settings (User address space size - 2GB), and I got a functioning network and the following: | Code: | bash-2.05b# /etc/init.d/net.eth0 restart
* Unmounting network filesystems... [ ok ]
* Stopping ntpd... [ ok ]
* Stopping sshd... [ ok ]
* Bringing eth0 down
* Removing inet6 addresses
* eth0 inet6 del fe80::208:74ff:fedf:2234/64... [ ok ]
* Releasing DHCP lease for eth0... [ ok ]
* Stopping eth0... [ ok ]
* Bringing eth0 up via DHCP... [ ok ]
* eth0 received address 192.168.1.105
* Mounting network filesystems... [ ok ]
* Setting clock via the NTP client 'ntpdate'...
host found : triangle.kansas.net
host found : cisco1-mhk.kansas.net
host found : dr-zaius.cs.wisc.edu [ ok ]
* Starting ntpd... [ ok ]
* Starting sshd... [ ok ] |
The only change I made in the kernel configuration was to increase the 'user address space size'from 2GB to 3GB! Is there something additional I must do to if I wish to make such a change and avoid eth0 problems? I'm perplexed by this.
dellaxim... I believe the above shows the dhcp server to be healthy.
Thanks, again, for your help.

cgmd,
It looks like your dhcp is not compatible with your new kernel. I wonder if you need to rebuild glibc or if its more subtle.

glibc is emerging at the moment. I'll post the outcome...

glibc emerged, but no change in network behavior. After restart, still no network.
Where next with this? Any thoughts?
Thanks, again...

cgmd,
It looks like your kernel change has broken dhcp. Your module is loaded becasue eth0 exits.
Its not glibc, which is used by almost everything on the system - you recomplied that.
The last thing I can think of to try is to rebuild the package that provides the dhcp client.
After that all thats left its static IP assignement if you can live with that.
It probably not worth trying another Network Card, since its not the driver that seems to be the problem.

NeddySeagoon...
Thank you for your patience and sharing your insight... I'm very appreciative!
Last evening I experienced a  moment, while modifying my grub.conf file. It occurred to me that the kernel line was pointing to a kernel (configured for me by someone else), from which I had migrated with recent bzImage changes. Simply changing the grub.conf line to, now, point to the new (modified) kernel has done the trick! My network works!
It is beyond me, why previous kernel changes always seemed to work, inspite of booting to a kernel which I assumed to be inactive for the past 6 weeks, and then to have this most recent kernel modification wipe out dhcp function? But, then, again, there's much I don't know about gentoo! 
Anyway, everything works (for the moment), and I'm happy about that.
Thank you, again, NeddySeagoon, for your guidance through this troubleshooting effort!
