Can't Connect To Internet In Linux Driver problem?

[foolakadugie 0]

I am new to linux and just installed Kubuntu. I have windows XP on my master primary hard drive

and Kubuntu is installed on my slave drive. Everything seems to work great except that I cannot

connect to the internet when I boot into Kubuntu (I also tried Ubuntu). I am thinking maybe it has

something to do with ethernet adapter driver. I can connect just fine in windows, so I know that

the actual hardware isn't messed up. Windows uses the driver for Realtek RTL8139/810x Family

Ethernet NIC. I looked through google and help forum threads and it seems others have had this

problem with similar adapters and many of them never came to a resolution and others got it

working and were not quite sure what got it working. Kubuntu is supposed to install the hardware

automatically and I really don't know how to install linux drivers. Does this sound like a driver issue?

I would really like to get this resolved, because I really can't enjoy an OS without an internet connection.

 

When I open the web browser and attempt a google search I get something like this:

"An error occurred while loading https://www.google.com/search?q=linux&i8&oe=UTF-8:

Unknown host https://www.google.de/?gfe_rd=cr&ei=BwkjVKfAD8uH8QfckIGgCQ&gws_rd=ssl;

 

 

I tried reinstalling kubuntu to see if that helped and then after booting back into linux

I checked the system log and these were the only entries:

02/07/2007 02:32:33 PM computername anacron[4478] Job `cron.daily' terminated

 

02/07/2007 02:32:33 PM computername syslogd 1.4.1#18ubuntu6 restart.

 

 

I tried opening network places and get this alert:

error - konqueror

The Zeroconf daemon (mdnsd) is not running

 

 

I followed some steps from different posts in other forums and I don't really know if they

apply to me or not but I will post the results I got to maybe assist in diagnosing the problem:

This means the eth0 couldnt get any ip address.

Do you have a DHCP server on the LAN ?

 

or you can do one thing.. have a static IP for the eth0 (assuming eth0 is the network card hooked on to your LAN). Open '/etc/network/interfaces'

 

and have something like this...

 

======

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

 

# The loopback interface

auto lo

iface lo inet loopback

 

# The first network card - this entry was created during the Debian installation

# (network, broadcast and gateway are optional)

 

auto eth0

iface eth0 inet static

address 192.168.0.50

netmask 255.255.255.0

network 192.168.0.0

broadcast 192.168.0.255

gateway 192.168.0.10

======

 

Remove all the other interfaces ie. eth1, eth2... till wlan0..

Now check...

 

Cheers

Well in windows under LAN properties it gives me an IP for the DHCP Server.
Does this carry over to Linux? Oh and if it matters, I am not behind a router.

I will boot into linux and if I can do what you suggested.

My Windows installation on my desktop uses Realtek RTL8139/810x NIC and the drivers get installed smoothly. On My laptop i use Intel Integrated 10/100 NIC.

 

Normally I assign an IP address to the Desktop and when i connect my laptop that has OpenSuSE 10.2, it gets detected automatically and all i have to do is fire up the browser and start working.

 

Instead of connecting via LAN, u could also try connecting your linux machine individually to the internet.Try this link >>LINK<<. Being a newbie myself this is all i could help you out with. But personally i would suggest anyone new to start with opensuse, cause it was easy and user friendly for me when i started.

Dhanesh.

I am now connected to the internet in kubuntu. I would like to thank both of you for your help. It seems kubuntu has a weird bug in recognizing an internet connection. It will tell you that it is enabled when it is not. I unplugged the ethernet cable, rebooted, disabled the eth0, plugged the ethernet cable back in, then re-enabled eth0,

Your eth0 couldn't connect.Srry I didn't read all of it.

hi,

that was not a bug. in reality, all system that are linux based requires you to setup the eth0 IP since it was the primary network connection. that autodetection was just an added feature.. =)

What saneax has said is the exact problem here. In case you find his instructions a little tough to follow, then try exploring the System menu in Kubuntu and goto Network Settings. You will find a tool that lists all the network interfaces including eth0. Select eth0 and then select properties and then make the configurations of IP, Subnet mask etc just same as in Windows. That will help.

internet connect when i work in lanCan't Connect To Internet In Linux

I have connectet my server system to  client system with eth0 by using the ip address,after I connect my lan I connect internet at this time the lan ip changed and I got problem with my lan how can I solve this problem

I am having the exact same problem with my Linux OS, I can't not connect to the internet as well. Have you found any solutions or have you connected to the internet?

I use "pppoe-discovery" to check if my dsl-modem is bound on eth0 or eth1, because my pc comes with two NICs and the bounding switch in a random wise booting a Linux LIVE-CD like Knoppix.

 

#!/bin/sh

sudo ifconfig eth0 up

if sudo /usr/sbin/pppoe-discovery -I eth0 | grep -q "AC" then

sudo ifconfig eth1 192.168.0.2 netmask 255.255.255.0 broadcast 255.255.255.255 up

else

sudo ifconfig eth1 up

sudo ifconfig eth0 192.168.0.2 netmask 255.255.255.0 broadcast 255.255.255.255 up

fi

 

sudo pppd call dsl-provider
