Network Problem with Mandrake 10.1 Official

[Guest Diodo]

Hi everybody.

I'm a newbie user of linux, and i have installed few days ago Mandrake 10.1

All was perfect, but the internet configuration. I couldn't set up it in the installation. Afterwards, with the installation complete, i still having problems, and finally I could set-up a working internet conection, by the option "Ethernet Connection"

Excuse me, i forgot it: my connection is ADSL, and i use a D-Link DSL-504T Router, on it, hi have connected 2 computers.

 

The problem: when mandrake say's me that it have been stablished connection with the ethernet card, i tried to navigate with Konkeror, but i couldn´t, he cannot find the servers.The same problem with mozilla/firefox.

Navigating in windows partition, i read something about deactivating in mozilla the IPv6 option. I tried in firefox and, it run!!!.

Later i check, that Opera also run, and I could run aMSN (linux messenger).

But the Azureus, Konkeror, FTP clients, IRC.. nothing works.

 

I think it could be something of DNS, because i tried this: I opened a IRC client, and i tried to connect to a server, it said NETWORK UNREACHABLE (Like the Azureus). Then I opened a Terminal and i did a ping to that server, it returned me the packets. Well. Then i tried to connect another time to the server and... it run!!

 

What could it be? (oh, my ISP sets automatically the DNS)

 

and excuse my poor english!

hello, diodo and welcome aboard.

 

i do know of your problem (had the same sh** on my 3 boxes). you are right about the ipv6 stuff. d-link (and most routers) use ipv4 by default, so they are sent into hell due to ipv6. i do not know yet how to deactivate ipv6 especially for konqueror but you could try one of the following things:

 

1.) open a terminal and log in as root (type "su" then enter root-password). now type:

echo "net.ipv4.tcp_window_scaling=0">> /etcsysctl.conf

 

2.) the other approach is (worked on most systems i used so far) installing the following packages: "resolvconf", "pump" and "dnsmasq".

 

after that, disable your network, edit your "/etc/resolv.conf" file as root and replace the router-entry (e.g. nameserver=192.168.1.1) with other dns-servers (like e.g. 217.237.150.141) you can find the name-servers of your area e.g. using google.

 

good luck. :)

I'm so happy now :lol: , yes, it was the IPv6, i added that string and 2 more in /etc/modprobe.conf :

alias net-pf-10 off

alias ipv6 off

 

And now all runs :D

 

I was . But i think that's something that i like of linux, when you solve something, it makes you feel .

 

These kind of problems are always following me, when I had 56k, with a Zoltrix, i cannot dial-up, it was because it needed a different dialing string (ATP*T)... well, i stop :lol:

 

Thanks other time, artic, i'm glad of discovering this forum, it goes directly to Favorites B)

These packages should all be available via urpmi, use Easy urpmi to help with setup if you need it.
