not able to configure internet connection in kubuntu
You can save the connections if edited at root.
There's two ways to set up your DNS.
1. Set your nameservers up in your router and use the router as the
nameserver (Best, as this will work across the entire LAN)
2. Set up just your computer to just use 'specified' nameserver.
These instructions don't use and GUI so they work for Ubuntu or
Kubuntu. I've found Kubuntu's network manager broken anyway (Especially
with wireless...) So my advice is to use gnomes network manager with
nm-applet or better yet, use Wicd. This will conflict with network
manager so it will be removed when wicd is installed. Wicd is much
cleaner and handles wireless autoconnects as well as wired connections.
I love it and believe it should be the default for both Gnome and KDE,
but some disagree with me.... All I know is KDE's front end is severly
broken and buggy in intrepid and later. I'm getting off topic but check
out Wicd, you won't regret it!
Add this to your /etc/sources list to try Wicd:|
deb http://apt.wicd.net hardy extras|
Substitute hardy with intrepid or jaunty if you're running 8.10 or 9.04
Then a simple sudo apt-get install wicd will install it. You can setup
your DNS nameservers in Wicd's front end...
If you prefer to set up the nameservers in your router, open up the
router config page in a browser (ie. Firefox) It's usually 192.168.1.1
for most routers, or may be 192.168.0.1 for some models... See the
router config docs for more info.
To open it up, just type:
in the address bar. In the Setup page (Usually the first tab on the
config page, look for your DNS nameservers. There will be two or
possibly three places to type in your DNS ip addresses. If you don't
know your ISP's DNS ip addresses, you can use OpenDNS's. They are free
and work great and are very resistant to any DNS poisoning attacks. For
more info on OpenDNS see http://www.opendns.com/homenetwork/solutions
So on these tabs add:
And save the config. If there's three places, just leave the third blank.
Now, open a terminal and edit your /etc/resolv.conf file:
sudo nano /etc/resolv.conf
and in the file it should look like:
Press CTRL-X and save it.
Remember, if your router uses a different address than 192.168.1.1
change this in your resolv.conf to point at the router.
If you don't want to use the router as your LAN DNS server, add:
to your /etc/resolv.conf file.
Hope this helps.
