internet is not working in linux but does in windows, altough i am new to linux i hav had help from a fairly knowlagable friend who can not help. i use an adsl router so i have tried lan and adsl connections without result. i have used the exact settins that windows use (and windows works) yet nothing. plz help

Hello,

First things first, I think that with a router, you'll need to configure a LAN connection to access the internet (I'm assuming that the router plugs into the ethernet port on your machine?). Go into Mandrake Control Centre and a dd a LAN connection, delete any other spurious connections (ADSL, etc.)

The problem could then be either DNS or actual routing. If you can get a LAN connection configured, post back and I'll try and diagnose it with you.

lan done (i think)
 

ok, i have done the lan settings i think. I think they are done because when i click 'connect lan' it comes up 'connecting to internet', after a while it says connection complete, then promtly turns to 'not connected' i tried ping 10.0.0.2 afterwards (as advised by a friend) and it came up 'network : Not reachable' , which confuses matters. i have an onboard ethernet adapter if that complicates issues

Type netconfig in a terminal window and set an IP address for your linux machine. This is assuming your router uses a set of allowed ip's. You will need to set one within this range.

In XP open a cmd shell and type 'ipconfig /all' and copy down the IP address, subnet mask, default gateway and DNS servers. Put that information into [whatever graphical utility it is you are using to set it in Linux.]

If that's what you already did, or you do it and it still isn't working open a shell and post the result of trying to ping:
the IP address you gave linux,
the default gateway,
one of the DNS servers,
an Internet IP address like 64.179.4.149
an Internet site by name like linuxquestions.org

.
 

ok first of all i tried 'ipconfig' and apparently yhat isnt even a command, i looked down the 'net' usage menu and config isnt there (i tried 'netconfig' and 'net config')
secondly, when i tried pinging 10.0.0.2 (my ip address as set by windows) it says
'network: not reachable'
when i tried pinging google 'ping www.google.com'
it says the domain isnt reachable

I think we need to clarify, when you say you have Windows and Linux, do you mean that one computer dual boots into either, or that you have 2 computers and one has XP while the other has Mandrake and they are both plugged into the same network?

ipconfig is the command you run, not in Linux but in Windows 2000/XP to see what IP address is set. If you run that command in Windows you can see what IP address is set there, to help you (and us) know what address to use in Linux.

When you tried to ping 10.0.0.2 and received the network: not reachable error was that in Linux? In Linux run the command ifconfig to see what IP address is set there, make sure it's set like you wanted it to be.

When you tried to ping google, that was in Linux I'm hoping, was the message 'unknow host' or was it 'destination [host or net] unreachable'?

If you have two computers running at the same time then you need to use different IP addresses for each computer, but they have to be close (on the same subnet.) If you have one computer with both Windows and Linux, set the IP address in Linux to the exact same one that is in Windows, but if you have two computers and the Windows one has an IP address like 10.0.0.2 then set the other computer to be all the same numbers except the last one, which can be any other number but 0, 1 or 255 so 10.0.0.3 or 10.0.0.54 or whatever you want.

clarity
 

i have two computers, a dual boot pc (myn) and an xp machine. Which is why i use a router....
when i set the ip configuration from windows in linux, linux still wont connect (well it comes up 'connected' then quickly changes to 'not connected' (which is confusing))
the ping problem said 'unkmown host' (sorry)
my computer has a different ip address to the other computer, but im trying to use the ip address of my box from windows in linux and keeping the other machine completly the same.

Please post "ifconfig -a" from you linux box

also post the output of cat /etc/resolve.conf

ifconfig -a is not a command (nor is ifconfig) and
cat /etc/resolve.conf doesnt exist....

any thing else?
 

i realise that this hasnt exactly been a walk in the park, so if there is any more advice the plz tell me, if there is nothing else tell me and i can take a hammer to my computer (or just try a new etho card. Thank you for all the help so far.

in xp as darin says u can use the ipconfig command
start>run>cmd this will bring up a terminal window or u can go to start>programs>accessories>command prompt either way u will get to the same terminal window
then type ipconfig>enter this will give u the ip addy u r using for windows + gateway + subnet OR u can ipconfig/all which will provide ur ISP dns server addy and the type of lan card u r using + mac addy + whether u have dhcp enabled.

In linux to use the command ifconfig u must again use a terminal window and change to root user.
su>enter password>ifconfig -a

try both these commands using each OS and post the output :-)

i hope this makes sense,
muffinman

it would seem that ur lan card does not have an ip addy assigned to it. Have u used mandrake control centre to set up your lan connection?

yup
 

i hav used it to create a lan connection using DHCP and static, because im not sure what does what. when im using static i use the settings windows uses, and dhcp is automatic. when i connect 'lan' it comes up as connecting to internet at the bottem of the dialouge, so i assume it means that my router has been recognised, it comes up as 'connected' then 'not connected' which i can only guess means that it can connect to the router, but not the internet itself, muffin

oops
 

i was using static when that happens by the way... sorry

Ok, I have been watching and waiting. I am not sure that your sure what your doing. If you followed darins post then there is no way that it couldn't work with most linux distros.

Now with that being said. Setup for DHCP. After you do that run ifconfig -a and post the output. We need to make sure that you are even getting an ip address from your Router. Also if you could give the make and model of your router it would be nice. If this is just an DSL modem then its only going to alow once connection and it will bind it self to that mac address from your windows box. Most of the time you can just turn off the modem and turn it back on with the linux box set for dhcp. Then open a browser and go your your modem setup page. I am not familler with mandrake but you have to have a reslove.conf file somewhere to have the dns settings.

You can manually setup a DNS recoerd or you could send your self through a proxy server to by pass this for the time being.

Have you tried to ping 10.0.2.1 from your windows box? See if you can get a reply. Ifso do the same with the linux box soon as you get an IP address.

Also can you make sure that your eth0 is even setup?

This all may sound stupid, but your computer should be working. Alot of people have problems with getting on the internet when new to linux, but thats what the internet runs on so don't give up on linux.

Here is my ifconfig -a from my fedora box
