Unable to load any home page

gellb · 01-01-2009, 03:16 PM

Hi Slackers,
I am unable to load any home page in my browser, nor ping any site. Althoug apparently I managed to setup the pppoe service properly because after pppoe-start, it connects.
What should be the problem?
(I have ADSL modem and an active Realtek ethernet PCI card. I also have a built-in ethernet card on the motherboad but I don't use it.)
Now I am writing from PuppyLinux because net works in Puppy.

Any help is welcome!

Please send the output of following commands, typed as root, when you suppose the connected is active:

Code:

ifconfig -a

then:

Code:

route

I am suspicious with this last line about IPv6 routers.

Any help is appricated!

Try pinging your gateway first:

Code:

213.181.206.9

If it works, resolving DNS addresses is broken.

There is a problem with your eth0 interface. It has only IPv6 address (inet6 addr) and therefore is missing traditional IPv4 one (inet addr). As well, no routing for this interface was specified in kernel routing table. I am not sure which card eth0 was bound to. It might be bound to the card you're not using.

However, ppp0 should work as it is labeled as default. So I suggest to solve this problem first and later concentrate on fixing ethernet.

gellb · 01-02-2009, 03:14 PM

Thanks, Alien for your help!

Meanwhile I managed to fix the DNS resolving problem. The solution was to edit /etc/resolv.conf and /etc/ppp/resolv.conf with the proper IP values. Therefore right now I am writing this reply from Slackware!

Although the IPv6 issue has remained.

Code:

bash-3.1# dmesg | grep eth
Driver 'st' needs updating - please use bus_type methods
Driver 'sd' needs updating - please use bus_type methods
Driver 'sr' needs updating - please use bus_type methods
eth0: RealTek RTL8139 at 0xc800, 00:0e:2e:f0:d1:8f, IRQ 17

eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
eth0: no IPv6 routers present

Remark: RealTek is my active ethernet card. I put the driver of the other eth card to the blacklist.

Any help is welcome concerning

The easy way to disable IPV6, edit /etc/modprobe.d/modprobe.conf and add the lines...

Code:

#Disable ipv6 the old way...
alias net-pf-10 off

...and edit /etc/modprobe.d/blacklist and add...

Code:

blacklist ipv6

You also need to modprobe -r ipv6 and restart your network daemons. Easy way is of course reboot (cringe).

gellb · 01-05-2009, 03:44 PM

Thanks, Astrogeek! With your codes I managed to disable ipv6 however I don't have ipv4 address for my eth0 yet. Anyhow my net connection is OK.

Code:

bash-3.1# ifconfig eth0

Alien_Hominid · 01-05-2009, 04:25 PM

Do you mean that you can connect with your eth0 card only (not using ppp)?

gellb · 01-06-2009, 01:41 AM

No, Alien. I need ppp, unfortunately. Any suggestion?

Alien_Hominid · 01-06-2009, 10:39 AM

Code:

ifconfig eth0 your_ip_address netmask 255.255.255.0
