Set up internet connection

trackrat · 03-14-2004, 09:33 AM

I have 2 computers my main one is XP the other one is a duel boot XP & mandrake 9.2.
I have both computers sharing the BB through a router, however being new to linux I have no idea how to access the internet on linux.
I have tried, but cannot find a way to set it up.
Can anyone supply me with a set of simple instructions.
Regards Alan.

If I've correctly understood your network architecture, the setup is very simple:
ifconfig eth0 inet your_linux_private_IP up
route add default gw your_router_IP dev eth0
And everything should go fine

I take it this is a command that has to be run.
Is it one continuous command and how do I open the command prompt box.

OK, you have two solutions: either you browse startup menu and try to find a program named Konsole, xterm, kterm, gterm or something lik that

or you switch from graphical mode to text mode by typing: <Ctrl>+<Alt>+<F1> and log as root

(return to graphical mode with: <Ctrl>+<Alt>+<F7>)
if you've choosed first solution, type

Code:

counter@CS-Debian:~$ whoami
counter
counter@CS-Debian:~$ su
Password:
CS-Debian:/home/counter# whoami
root

I explain: whoami is to know who you are... the ifconfig and route command requires root (super user) privileges. So if you are not root, type su to log as root and enter root password. Then retry whoami to see if you are root

then you can type:

Code:

ifconfig eth0 inet 192.168.0.25 netmask 255.255.255.0 up

to setup your IP address to 192.168.0.25 with a netmask of 255.255.255.0
and then:

Code:

route add default gw 192.168.0.1  dev eth0

to tell your system that the gateway is 192.168.0.1 and eth0 is the NIC to access it

I tried this after logging in as root from the Konsole and text and all I keep getting is bash unknown or bad command, so now I am more confused than ever

Ok, the problem is that your PATH variable is not correctly set up for root user. type this (always as root):

Code:

root@Olinux-lfs:~# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin

the PATH variable contains the path where to find your executables. ifconfig and route program are in /sbin directory. So if /sbin is not in the output of "echo $PATH" either you add it (temporaly):

Code:

export PATH=$PATH:/sbin

Then you can retry ifconfig and route commands
or you type the command with his full path:

Code:

/sbin/ifconfig eth0 inet 192.168.0.25 netmask 255.255.255.0 up
/sbin/route add default gw 192.168.0.1  dev eth0

I hope this time that'll work

I have tried your latest suggestion but when I type in root@olinux-lfs:~# echo $PATH it is comong up as a bad command root@olinux-lfs:~#
Would it be better to reinstall Mandrake 9.2 and configure the internet in the setup?

Sorry I made you make a mistake

In fact you just have to type echo $PATH ... You made a mistake cause I did a copy/paste from my shell, and I've included my bash prompt.
But the most important part is:

Code:

/sbin/ifconfig eth0 inet 192.168.0.25 netmask 255.255.255.0 up
/sbin/route add default gw 192.168.0.1  dev eth0

Tried the echo $PATH and this is the reply.
- bash: echo/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/games:/home/alan/bin: no such file or directory.
Does this help
A friend told me I was not using root and to type in the console su and then my password but this did not work either

you may find it easier to set up the appropriate scripts. I use redhat so this may not apply to you.

Check if there are files in:
/etc/sysconfig/network-scripts/

type this to check:
ls /etc/sysconfig/network-scripts

if you see something along the lines of 'No such file or directory' then this does not apply to you, otherwise continue

create/edit the file:
/etc/sysconfig/network-scripts/ifcfg-eth0

to look like:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

then restart your computer

trackrat · 03-17-2004, 04:55 PM

I got no such file or directory, thanks for your help and time .
How can I check I am in root as at the command I get [alan@local host alan] $. Is this root?

Oliv' · 03-18-2004, 07:27 AM

To check if you are root, type whoami. Another quick way to check if you are root or not is to see wether your prompt line ends with a # or not.
