Can't get internet to work in SuSE 9.1! Please assist! (DSL)

[Matttan8989]

I'm on a DSL connection, and Bellsouth is my ISP. I'm currently running in Knoppix, and it was able to detect my network settings just fine, it seems. I cannot get SuSE to allow me to get online. Help would be appreciated.

More info if you please, how are you connected to the internet? What have you tried? If connected through LAN can you ping your router from the command line? Have you gone to Yast and configured the connection?

help us help you.

Hi,

It sounds like your not being assigned an IP# from your ISP's DHCP server.
Open a terminal while using knoppix and type "ifconfig etho0" without quotes, this will display your IP#, MAC address, and your ISP's DNS server - Then run the same command under SUSE and see what's missing.

Also ... check your "/etc/resolv.conf" file in Knoppix and take note of the settings ... and then check it in SUSE and edit in your DNS servers IP# if it's missing or different from the Knoppix configuration.

Good Luck.

I connect to the internet through ethernet to a Westell modem. It's a DSL connection and this is the only computer on this network. I tried configuring the connection and network card in YaST using the documentation that came with SuSE. Later, I will try running the commands that you suggested and trying to configure it once again. (I was frustrated with SuSE, so I tried installing another build of Linux. This computer seems to reject Linux somehow. I tried Ubuntu, and the X server wouldn't start. I tried SuSE, and I'm having this problem. I tried Slackware, and couldn't get it to install. It's quite frustrating, thank you for the help.)

If you like SUSE but Knoppix configures your hardware better ... i can show you how to copy the settings from Knoppix into SUSE.

If your in a downloading mood ... grab SUSE 10.0.
The hardware detection is alot better and it's a much nicer version all around.

That would be most appreciated! But I don't really have the time for downloading and burning 5 blanks, so I'll go with the idea of copying the information from Knoppix to SuSE. Thank you very much.

It may be a case where the NIC has a conflict or is unsupported ... copying config files won't fix that. Plus the copying between machines is mainly for X settings, Kernel's, & modules.

Most of the Network support or lack of (as well as config's) differ from distro to distro. Even between Debian and Knoppix (with Knoppix being a Debian spin-off).

I didn't mean to raise false hope with the copying, but it would mean a kernel & Module replacement if it's an unsupported NIC in SUSE. It actually goes exceptionally smooth though.

Let's copy some basic settings and see if we can't wake this NIC up.

All commands surrounded by quote marks " " do not need the quotes when typed into your terminal.

-----------------------------------------------------

Run ifconfig in Knoppix (while online) and write all of the info down that you will need ... netmask, IP#, Bcast.

ifconfig

On very rare occasions you might find that your NIC card doesn't work because it shares both an interrupt and memory access address with some other device (IRQ).


cat /proc/interrupts

tim@linux:~> cat /proc/interrupts

You can see in the example from my machine above that etho0 is on a line by itself and using 185 ... No conflicts.
If your etho device is sharing the same number as another device then you have an IRQ (interrupt request) conflict.

---------------------------------------------------------

Your DHCP server not only supplies the IP address your Linux box should use, but also the desired DNS servers. Make sure your /etc/resolv.conf file is pointing to your ISP's DNS server.

Copy the namserver & Search (if applicable) address out of the Knoppix /etc/resolv.conf file.

Add or replace that Info in the SUSE /etc/resolv.conf file with the Knoppix info.

### BEGIN INFO
#
# Modified_by: dhcpcd
# Backup: /etc/resolv.conf.saved.by.dhcpcd.eth0
# Process: dhcpcd
# Process_id: 4691
# Script: /sbin/modify_resolvconf
# Saveto:
# Info: This is a temporary resolv.conf created by service dhcpcd.
# The previous file has been saved and will be restored later.
#
# If you don't like your resolv.conf to be changed, you
# can set MODIFY_{RESOLV,NAMED}_CONF_DYNAMICALLY=no. This
# variables are placed in /etc/sysconfig/network/config.
#
# You can also configure service dhcpcd not to modify it.
#
# If you don't like dhcpcd to change your nameserver
# settings
# then either set DHCLIENT_MODIFY_RESOLV_CONF=no
# in /etc/sysconfig/network/dhcp, or
# set MODIFY_RESOLV_CONF_DYNAMICALLY=no in
# /etc/sysconfig/network/config or (manually) use dhcpcd
# with -R. If you only want to keep your searchlist, set
# DHCLIENT_KEEP_SEARCHLIST=yes in /etc/sysconfig/network/dhcp or
# (manually) use the -K option.
#
### END INFO
search cityname.rr.com
nameserver 66.23.9.2

-------------------------------------------

Now with the Knoppix info in hand... Give eth0 interface an IP address using the ifconfig command:

linux:/home/tim # ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up

The "up" at the end of the command activates the interface. To make this permanent each time you boot up you'll have to add this command in your /etc/rc.local file which is run at the end of every reboot:

ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up

------------------------------------------------

Im on cable ... so the settings and info may look different than your DSL.

Summary:

1.) Run "ifconfig" in Knoppix + write down your information.
2.) Copy the very last 2 lines in the Knoppix /etc/resolv.conf file. All lines beginning with # are just comments and not info you need.

--------------------------
Back in SUSE

3.) Run "ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up" replace the info with that from Knoppix.
4.) Open the /etc/resolv.conf file in SUSE and replace the last 2 lines with the info from Knoppix.

See if you can blast off into cyberspace.
