Wierd internet problem

scompa · 05-17-2006, 03:07 AM

I have really strange problem. I type: # pppoe-start and it echoes: # .Connected!, so it means I am connected to internet, but when I try to ping google it wont work, or open page in firefox, dont work. It don't says unknown host, but nothing. I can't find the problem...

Look at "ifconfig -a" and check the output of ppp0 (or whichever ppp you use).

Try pinging the nameserver address for your ISP, eg for me I use Wanadoo, onr of their nameservers is 192.95.192.94, it's the computer one connects to to transform names, eg "yahoo.com", into numbers ("216.109.112.135" for yahoo.com for me) so you can transfer data between your computer and one on the net.

If you can ping name server IP, make sure the DNS server IP is in your '/etc/resolv.conf'.

I can't ping it, it says Destination host unreachable. What next?

drkstr · 05-19-2006, 09:53 PM

Are you getting an ip address? Please post the output of 'ifconfig'.

I am getting IP and only what I can ping is 172.29.252.6. I can't ping google.com or google's IP address. I don't know ISP's DNS address. Acctualy, I know, but I am not sure is that correct address. I can't ping it. Home network is working properly.

Enter your nameserver into your config, you can do this by typing:

echo nameserver x.x.x.x >> /etc/resolv.conf

or you can manually edit /etc/resolv.conf using VI, Emacs or Gedit.

Then try pinging this:

72.14.203.104 (Google)

Basically if your config is correct you should be able to ping that by IP, if your nameserver is correct you should be able to ping www.google.com. Since you say you can't ping the IP I'm curious to what else is wrong. Can you ping your eth0 int, the 192.168.0.10? You're using PPPoE, DSL? What ISP are you going through?

drkstr · 06-02-2006, 03:16 PM

Well you are connecting OK to your ISP, and you can not ping the DNS server's IP, so it is most likely a routing problem. Run the command 'route -n' and see if you get an output something like this:

Quote:

Kernel routing table
Destination Gateway Genmask Flags MSS Window Use Iface
172.29.252.6 * 255.255.255.255 UH 1500 0 1 ppp0
...
default 172.29.252.6 * UG 1500 0 5 ppp0

If you didn't get something like this, then your system is probably assigning the default route incorrectly.

If this is the case, open the /etc/rc.d/rc.inet1.conf, find the line GATEWAY="" and change it to this:

Code:

GATEWAY="172.29.252.6"

You can then restart the service by:

Code:

sh /etc/rc.d/rc.inet1 restart

Once your gateway is configured correctly your /etc/resolv.conf file should be poulated by your ISP's DNS server automaticly. If it did not, you will need to add the line

Code:

nameserver <DNS server IP>

If it still does not work, please post what you got for 'route -n'

Even if it does work ... don't forget to post how you resolved it to help those searching in the future.

scompa · 06-03-2006, 12:16 PM

Drkstr, thank you very much, route was problem. T1ckT0ck, than you too for nameserver. I am trying to reslve this problem for few days but nothing helped. I just added gateway, restarted rc.inet1 and it worked!

I still have one more problem. On computer I have installed Windows XP too. When my network card is working, the small (LED) light is on, and when it's not working it's off. When my computer is shutted down light is sometimes on, and when I turn on my computer and boot Slackware, network in Slack work only if light was on before booting it (Slack).
Problem is that Slack won't recongise my card if light is turn off while booting. Stupid XP turns that light off on shutdown so my card won't work on Slack. I have to manualy shutdown XP (press 'turn on' button on comp) so my card continue on to work and light glow. So, why Slack won't turn on my card as XP would. I don't wan't to shut down XP by force. Light turns off too if I disconnect my laptop from AC power while it's shutted down.

drkstr · 06-03-2006, 01:53 PM

HMM, maybe there are some bios settings that relate to it? I'm not sure what exactly to look for, but go though all the options and see if you have anything about "wake up LAN" or something like that. Maybe someone else can provide some better feedback on how to get SLackware to wake up your ethernet card so you don't have to change the BIOS settings.

regards,
...drkstr

scompa · 06-03-2006, 03:25 PM

Nothing... There is nothing in BIOS about LAN. BIOS on my laptop is very limited. But I think there is an optin "wake up LAN" in Windows. I try that in few minutes.

osor · 06-03-2006, 03:55 PM

It also might have do with sleep states of the device. Try to put power management in your kernel.

scompa · 06-03-2006, 08:42 PM

And how do I do that? I am a newbie in Linux...

hunterfighter · 09-02-2006, 03:54 AM

Haha I face the same problem with you. After i alter the rc.inet1.conf and route add default ge <ISP GATEWAY> it still the same problem to me.
