Problem about accessing Internet.

snowball0916 · 02-18-2007, 03:35 AM

Hi,
I installed slackware 11.After setup the pppoe,I found it can obtained ip address.But it can't work.
Before pinging google ,i shut down the iptables and it return me a sentence:Unkown host.So what should I do?

blackhole54 · 02-18-2007, 06:14 AM

I was not clear from your post whether or not you tried pinging google, and if so what the result was. But I am wondering if you are having DNS problems. To check that out, in sequence, see if the following commands work, or if they return errors.

Code:

ping localhost
ping 64.179.4.146
ping www.linuxquestions.org

If the first two work but the third does not, then you have a DNS problem. Otherwise, we need to look elsewhere.

hello snowball0916,

Just a quick questions. Have you tried opening a terminal command propmt, logging in as the root user and typing "netconfig"?

The first thing netconfig does is let you enter a hostname.

hi,this is some information of my internet problem:

Code:

#ping www.google.cn
ping: Unknown host www.google.cn
#more /etc/resolv.conf
nameserver 202.103.225.68
nameserver 202.103.224.68

#pppoe-status

And this is some information of my Windows XP:

Code:

PPP adapter 宽带连接:

        NetBIOS over Tcpip. . . . . . . . : Disabled

If you don't know that chinese words,ignored them.

And you know loging between Linux and Windows is rather troubling me.Thanks.

hi,I didn't use netconfig command.And when at the end of the slackware 11's installation ,i just enter as default.but in pppoe-setup ,i enter the dns.Is that matter?

snowball0916 · 02-18-2007, 07:42 PM

And I tried to ping 64.179.4.146 ,it didn't work.I pinged www.linuxquestions.org ,it showed "Unknown host: www.linuxquestions.org"

But I can ping localhost.

I think you didn't set up the network properly, read the slackbook section on that:

http://www.slackbook.org/html/book.h...-CONFIGURATION

blackhole54 · 02-18-2007, 10:43 PM

Even though your interface appears to be up, it looks like you aren't getting out to the internet at all. If H_Tex_Mex_H's suggestion doesn't solve things, could post the output of

route -n

snowball0916 · 02-19-2007, 08:08 AM

This is the detail:

Code:

root@localhost:~#route -n
Destination       Gateway      Genmask         Flags    Metric    Ref Use  Inface

I don't know why my gateway is : 0.0.0.0

Hi,

You really don't have the ppp device setup completely. Without doing all the work for you, look at the howto; DSL-HOWTO Look at section 3.2.1 since you seem to be using a static IP. You should read the whole howto to get some solid background. My sig has some good online refernce to assist, this will help you a lot.

Since you didn't provide all the information needed to help diagnose the problem. I assummed that you were using a dsl modem. Your windows xp information leaned me toward that assumption.

You should look at the link 'How to ask questions the smart way'

You need to provide the necessary information to allow us to help you.

The last line of the routing table shows your default gateway to be 192.168.1.1. The zeroes in the destination and genmask columns (this combination of IP address and mask is generally written 0.0.0.0/0 or 0.0.0.0/0.0.0.0), will match any IP address. This is how packets not matching any more detailed address/mask will be routed.

EDIT: I told you to use the -n option with the route command because that is how I do usually do it. If you give the command w/o any options, things might be clearer to you, but the command might take a long time since it will try to do reverse DNS lookups.

snowball0916 · 02-21-2007, 02:54 AM

I am very sorry.
I tried to read that book these days, but I didn't find my error.
I am afraid it's some difficulties for me to read that books,since my english is not good and my understanding about slackware is little.
I think my choice is wrong this time.
Maybe I should continue my study on FC.
But thanks all of you ,anyway.
And I will still keep watching at slackware and I will turn back to slackware one day.

Regards,
snowball

The Slackbook has been translated into many languages ... hopefully you speak one of these better:

http://www.slackbook.org/translations.html

And, you're not supposed to be looking for your error ... look for how to set up your network properly.

I suppose you might not care anymore, but the best things come to those who don't give up ...

snowball0916 · 02-21-2007, 07:30 PM

Thanks again,H_TeXMeX_H
I found none of the translation of my mother language.
I once heard a friend told me:"Learning Linux should learn well in a version,but don't try every version for beginners.When you learn well in the version or go though the version,you can try another or not,otherwise you will learn noting on linux."
I think it's correct.
I know little.I need more.

H_TeXMeX_H · 02-21-2007, 07:37 PM

Ok, then ... I started out on FC4 ... it was relatively easy to learn, but it had problems, and they have only grown. FC6 for example is completely messed up (IMO).

Unfortunately, although I've tried many many many distros, the only one I can recommend is Slackware. I also liked Zenwalk (Slackware-based) to some extent.

Good luck ...
