 Posted: Fri May 29, 2009 1:10 am Post subject: Cannot connect to internet during installation! |
 |
|
Hi all!
I am a long time Windows user making a leap from Ubuntu to Gentoo  
I cannot for the life of me get an internet connection working while installing off of my Gentoo Minimal AMD64 CD!
I will provide all of the information I can, and appreciate any help..
I am using an HP laptop.
My ethernet cords, router, and DSL modem are fine. I have the DHCP server enabled on my router, and it does not start until 192.168.2.10
The result of any 'ping' is always "ping: unknown host www.(anything).com"
'ifconfig' shows 'lo' and 'eth0', which I have verified as my integrated network card.
forcedeth is automatically in use.
'/etc/init.d/net.eth0 start' outputs "* Caching service dependencies ... * WARNING: net.eth0 has already been started. [ ok ]"
'net-setup eth0' -> 'Use DHCP to auto-detect my network settings' does not seem to alter anything. At this point I entered my router's setup menu from another computer. My laptop has been assigned a lease at 192.168.2.10.
'net-setup eth0' -> 'Specify an IP address manually' changes the numbers that appear at 'ifconfig eth0', but I still cannot ping anything. The values I am entering are correct and work in Windows.
'lspci | grep Ethernet' shows "00:14.0 Bridge: nVidia Corporation MCP51 Ethernet Controller (rev a3)"
'route' shows
| Code: | Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 192.168.2.1 0.0.0.0 UG 0 0 0 eth0 |
Also these are my network settings in Windows, and what I entered during net-setup;
My IP = 192.168.2.5
Broadcast = 192.168.2.255
Subnet = 255.255.255.0
Gateway = 192.168.2.1
DNS Server = 192.168.2.1
Finally neither of the status lights on my network card ever turn on in the Gentoo CD. These two lights are always on in Windows, Arch, Ubuntu etc. To me this would indicate that Gentoo/Linux Kernel is not seeing my card properly, but when I interrogate it with the stuff above there doesn't seem to be a problem! If it is relevant, I did not have to do anything fancy (or, at all really) to get this network card working in the Arch Linux installer or Ubuntu.
Not sure what else I can try!
Thanks again for any suggestions. |

| use an ubuntu livecd of the same bitness as your intended install. then follow the gentoo handbook. The minimal cd is just a platform, any same bitness livecd or installed system will work as well. Get the stage3 tarball from the gentoo mirrors' releases/<arch>/current directory. |

Sounds very familiar. I had a very similar problem on my Asus P5N-E SLI with the integrated NIC. lspci reports the same Ethernet controller on my box.
Oddly, I never really truly resolved the issue. The weird thing was that networking worked great on my existing HD install (Arch Linux 64) and did not work on any live CD I tried. It "resolved" itself when I threw in an extra 10/100MB NIC I had laying around - after which both NICs worked on all my LiveCDs.

oh I'm well aware 
I did about 500 searches before I made my thread 
Too bad I have a laptop, destroying any flexibility like this that I may have had..

I have an Ubuntu AMD64 Live CD and the AMD64 stage3 tarball file saved in Windows (currently the only OS I have installed).. Now the dumb question, how do I use the two to install Gentoo? |

assuming your laptop has a 64 bit processor
boot the ubuntu live cd
open a terminal window
run | Code: | | su mkdir /mnt/gentoo |
open browser, browse to http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?style=printable&full=1#book_part1_chap4 , the gentoo handbook. Follow the handbook. You will have to be in ubuntu as root or use lots of su's.
If you have not already done so, reading through the handbook before starting is a good idea.
If Ubuntu CD will read your ntfs partition you can use the stage3 tarball you stored there, | Code: | su mkdir /mnt/ntfs
mount /dev/sda1 /mnt/ntfs |
when the tarball is called for find it under /mnt/ntfs/ and cp it to /mnt/gentoo. Probably as easy to download a fresh copy to /mnt/gentoo.
BTW your base problem may be a bios setting for your nic that does power saving or green. |

Well I got everything installed and setup ok in the Ubuntu Live CD (or so I thought), but when I went to reboot I ran into a problem.
"The superblock could not be read or does not describe a correct ext2 filesystem"
What does this mean? It occurs after the GRUB menu, while Gentoo loading stuff (so I'm assuming it's not a problem with grub.conf or fstab?). And of course, pressing "Ctrl-D to continue" just restarts the system.
Thanks for any ideas! |

boot the ubuntu cd or ubuntu, whichever is easy, mount the / and /boot partitions, run:
| Code: | cat /etc/fstab
cat /boot/grub/grub.conf
fdisk -l
mount |
and post the results here.
My guess pending data is fstab. |

Fstab it is:
Replace with:
| Quote: | /dev/sda2 /boot ext2 defaults,noatime 1 2
/dev/sda4 / ext4 noatime 0 1
/dev/sda3 none swap sw 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 |
and give it a reboot.
This one happens all the time. |

poop i still do not have internet access.. The lights on my NIC are working now, and I can ping my router and other computers on the network successfully, but things are still
Did I configure my kernel wrong? Or are there other possibilities here? |

you are describing a domain name service problem.
run:
| Code: | ifconfig -a
cat /etc/resolv.conf
cat /etc/conf.d/net |
and post the results. |

Every time I restart the computer resolv.conf resets itself, but DHCP is off 
Why might this be happening? |

do away with | Code: | | dns_domain_lo="homenetwork" |
check/fix resolv.conf and try | Code: | | /etc/init.d/net.eth0 restart |
dns_domain_lo="homenetwork" also wipes out resolv.conf with every net. start |

ok the internet is now working splendidly thanks to you two, but of course another problem.
I have tried to 'emerge --sync' four times now, and every time without fail [but each time at a different point in the process] I am met with kernel panic
Worse, nothing appears on the screen. The only indication I get is the caps lock light blinking.
Is there any way to troubleshoot this? A dump file somewhere when this happens? |

run
| Code: | df -iah /dev/sdb1
df -ah /dev/sdb1
tune2fs -l /dev/sda4 #change sda4 to be the device(partition) your /usr/portage directory is on (if necessary). |
and post the results.
there is a chance you are out of room or inodes or the ext4 fs is misfiring. |

not either of those, boot cd, run
| Code: |
umount /dev/sda4
fsck /dev/sda4 |
hoping the fsck program is present and current |

out of ideas
you might start a new thread titled to reflect exactly this problem like 'computer locks up during emerge --sync' maybe replacing 'computer' with model or cpu/motherboard
could be hardware, NIC or cpu heating? |

Post your kernel .config, the results of lspci -n and cat /proc/cpuinfo as well as your /etc/fstab. I'll check for kernel issues.
Blessed be!
