 Posted: Wed Feb 20, 2008 4:53 am Post subject: No network after install |
 |
|
Hi All, total noob to Gentoo... did the genkernel install from the min install disk. Had networking all during the installation (did it over ssh for heaven's sake) once I had a successful reboot, I have no network. Eth0 has an ip address, but I can't see the router it's getting the address from.
LiveCD works great, by the way...
Thanks! |

Could you please post a little more information regarding your setup? What is your NIC? What is the output of ifconfig after your reboot? Can you also post the contents of /etc/conf.d/net ?
Admittedly, I have absolutely no experience with genkernel as I've always configured my kernels by hand. I would be happy to help you learn how to configure your kernel manually if you'd like, but let's see if we can get this eth0 problem taken care of firstly.

I would also check you /etc/resolv.conf and make sure you have a valid nameserver in there. Can you ping/surf to an IP address?. Gentoo.org is 204.74.99.100

Working on getting this info... but I can't ping anything, even my router... but live CD works fine... and I did copy nameservers to resolv.conf... |

I appreciate it... I tried manual, and got a strange error halfway through... I think my boot partition was too small, so I rebuilt with genkernel just to see if i could get it running... |

/etc/conf.d/net is:
config_eth0=(dhcp")
dhcp_eth0="nodns nontp nonis"

Most probably genkernel didn't build the drivers for your NIC.
Whats the result of
| Code: | | lspci | grep -i net |
Can you find your drivers built in your kernel?
| Code: | cd /usr/src/linux
make menuconfig
Device Drivers -->
Network Device Support -->
appropriate section for your NIC
|
Also what's your kernel?
The result of an ifconfig would be most helpfull as well.

Look like this is the case.... lspci came back as an unknown command...
Live CD gave me: | Code: | | 02:09.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip compatible 10/100 Ethernet (rev 31) |

Hard for me to tell... lots of stuff loaded in there, and this is an old Dell, not 100% sure what the Ethernet card is...
| Bio wrote: | Also what's your kernel?

Here's the kernel, which is different than the liveCD: | Code: | | Linux olddell 2.6.23-gentoo-r8 #1 SMP Tue Feb 19 20:54:37 CST 2008 i686 Intel(R) Pentium(R) 4 CPU 1600MHz GenuineIntel GNU/Linux |

That's because you need to emerge pciutils.

According to your ifconfig output your NIC card's drivers are loaded. But you can make sure by checking your kernel config :
| Code: | cd /usr/src/linux
make menuconfig
Device Drivers -->
Network Device Support -->
Ethernet (10 or 100Mbit) --->
Tulip family network device driver support -->
[*] Early DECchip Tulip (dc2104x) PCI Support
[*] DECchip Tulip (dc2114x) PCI Support

I don't see anything wrong, are you sure you're on the same subnet as your router? What's your router's IP?
Also what's the result of
Indeed 5MB is a bit small

These were set to module... recompiling now.

Everything is DHCP, and yes, the subnet is fine... will post route after recompile...
Thanks! |

After recompile, I could ping the router... then I started sshd, and the network seems to go away...
I'm wondering if my NIC isn't going south. |

There is a problem with a line in your /etc/conf.d/net. It should read:
| Code: |
config_eth0=( "dhcp" )
|
Check to make sure that is exactly how the first line is written.

Just a typo... no internet means I have to type all the info manually...
Starting over right now... will choose a manual kernel install next... |

Oh, okay, I just wanted to make sure.  Welcome to the fold; we've all reinstalled Gentoo many times during the learning process. As I said earlier, if you want or need any help with the manual kernel configuration, please just ask.

try the following :
| Code: | ifconfig eth0 192.168.1.XXX netmask 255.255.255.0 broadcast 192.168.1.255 (where XXX is the final IP address byte of your NIC)
route add default gw 192.168.1.YYY (where YYY is the final IP address byte of your router)
|
Then try surfing, sshing, ftping etc(ing)....

Thanks! Manual doesn't look too difficult, although I just got done, and I have exactly the same problem...Some damn thing isn't getting loaded...I ran the whole install over ssh... so my network is fine... |

Tried that, I'm assuming those are two different commands, right? Didn't seem to affect anything. The route command came back with file already exists.
I used 192.168.1.26 for the first line, and 192.168.1.1 for the 2nd. |

Your route is good. Your kernel looks good also. As for ifconfig.
That's it I'm officially clueless

Well, it's good to know I didn't bonehead something!
So does anyone know the difference between the live CD networking and a standard install? Obviously, there's something loaded that I'm not installing...
I get the net up for about a minute before it goes away...very odd... |

On your /etc/conf.d/net, try leaving just the one line:
| Code: |
config_eth0=( "dhcp" )
|
and commenting out the others using the #. Also, is there an onboard NIC on this computer?

Nope, it's a PCI card. |

Did that, same damn thing... strange stuff is, it works until I start SSHd... wonder if I'm looking in the wrong spot? Could the sshd_config file have something in it that wacking the networking? |
