Re: Howto: Ethernet connection without a GUI

When I wrote the howto I did not consider that someone would be using it remotely. Glad you got it worked out.

Re: Howto: Ethernet connection without a GUI

I seem to be having similar problems with getting (K)Ubuntu net-working on a circa 2003 IBM/Lenovo Netvista machine where I would like to be running Linux.

Except for deleting the KDE networking manager programs, I think I have followed most of the directions in this thread. The built-in network card works with (UGH!) Microsloth (on a separate HD) but not with Kubuntu 9.10 on another HD.

I get the temporary IP address in ifconfig with settings for DHCP. My router is set for DHCP and I get a listing for the Linux box (an IP address x.x.x.103) with a MAC address matching the built-in NIC (and another test with an _OLD_ additional NIC card).

Trying the static configurations still doesn't allow me to connect with my LAN/the internet.

I cannot ping my router as the false IP address I have cannot reach the router at 192.x.x.x.

I've been struggling with this for a couple of days now. I can't get anything out of this machine. If I were to try to get output, it would be transcribed from one machine's screen to another on my LAN. USB sticks don't seem to be recognized either (That's a different thread somewhere.)

I've enjoyed the versatility of (K)Ubuntu for a Linux environment, I just have had problems with machines that didn't like Linux. I hope that this scant outline might provide some point of departure for a solution to my problem.

If you don't do that, then the rest of the howto is not going to help. The whole premise of this is to get your network running without a network manager screwing things up.

Re: Howto: Ethernet connection without a GUI

Thank you for the reply Detonate.

I've gone back and deleted the kde-network programs, rebooted, checked all the settings and I'm still not able to connect with my Kubuntu (8.04) Linux box through my router with DHCP. Other machines on my LAN are connected.

Perhaps my transcription of what I see will help solve my problem.

ifconfig shows two NICs connected with eth0 with a false IP address.

bucky@localhost:~$ ifconfig -a
eth0   Link encap:Ethernet HWaddr 00:09:6b:d5:aa:f6

Looking at the modified interfaces file, eth0 is set for DHCP as prescribed.

bucky@localhost:~$ cat /etc/network/interfaces
# network interfaces

# the loopback network interface
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

# the primary network interface
auto eth0
iface eth0 inet dhcp

# the secondary network interface
# auto eth1
# iface eth1 inet dhcp

The resolv.conf file is set to external DHCP servers as well as the IP for my router--which is the same as in your example.

bucky@localhost:~$ cat /etc/resolv.conf
nameserver 192.168.0.1
nameserver 208.67.222.222
nameserver 208.67.220.220

My router is set to serve DHCP addresses and it seems to have located the Linux box's NICs and their MAC addresses.

Restarting the network doesn't seem to be able to locate the router's DHCP server. Bummer.

bucky@localhost:~$ sudo /etc/init.d/networking restart
sudo: unable to resolve host localhost

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 11
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

And then obviously, my Linux box cannot ping the router or other machines on the LAN.

bucky@localhost:~$ ping -c3 192.168.0.1
PING 192.168.01. (192.168.0.1) 56(85( bytes of data.

--- 192.168.0.1 ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 20076ms, pipe 3

As expected, other machines on the LAN and the router get 100% packet loss trying to find the Linux box.

Obviously, I've done something wrong or am missing some detail here.

Perhaps it's my karma. High overcast, mid 50s. I should be out planting my garden or up the Poudre fishing.

Thanks for helping to solve my network problem.

Re: Howto: Ethernet connection without a GUI

What do you have in /etc/hosts

[buckyjunior]

Re: Howto: Ethernet connection without a GUI

Detonate.

the /etc/hosts file.

127.0.0.1  ibm/a0a5d118e94

# the following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
fe00::0 ip6-mcastprefix
fe02::1 ip6-allnodes
fe02::2 ip6-all-routers
fe02::3 ip6-allhosts
192.168.0.1 DI-524

Hmmm. I would speculate but I'm really in a foreign land here.

Re: Howto: Ethernet connection without a GUI

First, I would recommend disabling ipv6.

A search on this, or on the Ubuntu forum will tell you how to do this. I think that may be your problem.

[skunk]

Re: Howto: Ethernet connection without a GUI

bucky@localhost:~$ sudo /etc/init.d/networking restart
sudo: unable to resolve host localhost
...

Surely you need to have (at least) localhost defined in your /etc/hosts file

[buckyjunior]

Re: Howto: Ethernet connection without a GUI

Adding localhost to the /etc/hosts file, 127.0.0.1 seems to be now recognized as localhost.

As per http://kubuntuforums.net/forums/inde...opic=3108234.0 followed by the link to disable ipv6 at http://www.webupd8.org/2009/05/how-t...tu-jaunty.html, I set about to disable ipv6.

I get a response that the file

/proc/sys/net/ipv6/conf/all/disable_ipv6

does not exist.

Editing

/boot/grub/menu.lst

and rebooting does not change anything. The file still doesn't exiist and I'm still not able to connect. I still get a self-generated IP address instead of the router suggested address.

I'm certainly at a loss.

Re: Howto: Ethernet connection without a GUI

Try rebooting your router. Turn it off. Leave it off for a few minutes. Turn it back on. Then see if you get a dhcp offer from the router.

[buckyjunior]

Re: Howto: Ethernet connection without a GUI

Detonate,

Don't you ever sleep, or eat? You always seem to be here.

I rebooted the router which wiped out the references to the MAC addresses associated with the hardware on the Linux box.

A quick ping from the Linux box turned up nothing.
Restarting the network--again didn't receive any DHCPOFFERS from my router.

Is there something about
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval (number varies)
?

Isn't it supposed to be looking to my defined DHCP server/gateway? 192.168.0.1.
The $ff.ff.ff.ff seems like a mask to either nowhere or anywhere. This is getting deeper into unknown territory for me.

Do you think another distribution (not Debian based) might have some antique network routines that would better recognize my ~2002 vintage NIC card and router from probably the same era?

Or in your experience, are the possibilities narrowing toward a solution?

Re: Howto: Ethernet connection without a GUI

For information only.

I've given up trying to get Linux to play nice with the NIC on the old IBM/Linovo desktop. My guess is that it may need proprietary drivers. Drivers that work are apparently included in the Windoze installation.

My (less than optimal) solution to meet my current needs is to run Virtual Box on the original XP disk and install Kubuntu on that. The NIC does all the things is it supposed to do through Virtual Box.

Thanks for trying folks.

Re: Howto: Ethernet connection without a GUI

Also for information and to say a big THANKS to you, Detonate!

I didn't see any eth0 when I ran ifconfig but I did see lo.

I went ahead and followed your guide.

Happily I have a working wired connection again! I'm using 10.04, Lucid Lynx also.

I'm still puzzled as to how the connection got lost but I have your excellent fix to refer to now.

Many thanks from a UK Linux noob.

Happy to be of help. Great you got it working!!
